[Case of Streptococcus salivarius bacteremia/meningoencephalitis leading to discovery of early gastric cancer].
    Rinsho shinkeigaku = Clinical neurology, 2012, Volume: 52, Issue:5

    A 73-year old man was brought to our hospital because of acute onset of fever and consciousness disturbance. He had been hemodialyzed three times a week because of chronic renal failure since 13 years ago. Neurological examination revealed deteriorated consciousness and neck stiffness. A lumbar puncture yielded clouded fluid with a WBC 7,912/mm³ (polymorphonuclear cells 88%, mononuclear cells 12%), 786 mg/dl of protein and 4 mg/dl of glucose (blood glucose 118 mg/dl). Brain CT and MRI were unremarkable. He was treated with ceftriaxone and ampicillin. Streptococcus salivarius was isolated from the blood sample, but not from cerebrospinal fluid. The patient responded promptly to antibiotics therapy (ampicillin 3g/day, ceftriaxone 1g/day), and within several days he became lucid and afebrile. Isolated S. salivarius was sensitive for ampicillin and ceftriaxone. We diagnosed this case as S. salivarius bacteremia/meningoencephalitis. A gastrointestinal diagnostic workup revealed an asymptomatic gastric adenocarcinoma. S. salivarius is a common inhabitant of the oral mucosa that has been associated with infection in different sites. Meningeal infection by S. salivarius generally related to neoplasia of colon or iatrogenia, has been described on few occasions. This is the first report of S. salivarius bacteremia/meningoencephalitis associated with gastric neoplasm. Neurologist should be aware of the association of S. salivarius bacteremia/meningoencephalitis and gastrointestinal disease.

Early treatment response to piperacillin/tazobactam in patients with bloodstream infections caused by non-ESBL ampicillin/sulbactam-resistant Escherichia coli: a binational cohort study.
    Infection, 2023, Volume: 51, Issue:6

    This study aimed to compare treatment outcomes for bloodstream infections (BSI) caused by a piperacillin/tazobactam (PIP/TAZ)-susceptible E. coli among three patient groups: BSI caused by ampicillin/sulbactam (AMP/SLB)-resistant isolates treated with PIP/TAZ, BSI caused by AMP/SLB-sensitive isolates treated with PIP/TAZ, and BSI caused by AMP/SLB-resistant isolates treated with another monotherapy.. This retrospective study was conducted in two academic centres in Europe. Adult patients with E. coli BSI were screened from 2014 to 2020. Inclusion criteria were non-ESBL BSI and initial monotherapy for ≥ 72 h. To reduce the expected bias between the patient groups, propensity score matching was performed. The primary outcome was early treatment response after 72 h and required absence of SOFA score increase in ICU/IMC patients, as well as resolution of fever, leukocytosis, and bacteraemia.. Of the 1707 patients screened, 315 (18.5%) were included in the final analysis. Urinary tract infection was the most common source of BSI (54.9%). Monotherapies other than PIP/TAZ were cephalosporins (48.6%), carbapenems (34.3%), and quinolones (17.1%). Enhanced early treatment response rate was detected (p = 0.04) in patients with BSI caused by AMP/SLB-resistant isolates treated with another monotherapy (74.3%) compared to those treated with PIP/TAZ (57.1%), and was mainly driven by the use of cephalosporins and quinolones (p ≤ 0.03). Clinical success, 28-day mortality, and rate of relapsing BSI did not significantly differ between the groups.. Our study suggests that initial use of PIP/TAZ may be associated with reduced early treatment response in E. coli BSI caused by AMP/SLB-resistant isolates compared to alternative monotherapies.

[Multiple well demarcated skin erosions and ulcers following exanthematous drug eruption after sultamicillin therapy].
    Der Hautarzt; Zeitschrift fur Dermatologie, Venerologie, und verwandte Gebiete, 2018, Volume: 69, Issue:6

    This article presents the case of a patient with newly developed skin erosions and ulcerations following an exanthematous drug eruption due to sultamicillin therapy. The skin lesions were treated topically with clobetasol and prednicarbate and orally with methylprednisolone. A skin smear revealed massive growth of Escherichia coli bacteria. Blood cultures were negative. The cause for developing ecthyma gangrenosum in our patient were iatrogenic immunosuppression and transient bacteremia.

Clostridium paraputrificum Bacteremia in an Older Patient with No Predisposing Medical Condition.
    Internal medicine (Tokyo, Japan), 2017, Dec-15, Volume: 56, Issue:24

    We herein report a rare case of Clostridium paraputrificum bacteremia in an elderly (88-year-old) man without a predisposing medical condition. Although he had a history of anaerobic bacteremia approximately eight months prior to admission, no gastrointestinal disease was discovered. He was treated with intravenous ampicillin/sulbactam. This case suggests that C. paraputrificum bacteremia can result from only minor abnormalities in macroscopically normal mucosal barriers. To our knowledge, this is the first report of C. paraputrificum bacteremia in Japan.

Bacteremia Due to Arthrobacter creatinolyticus in an Elderly Diabetic Man with Acute Cholangitis.
    Japanese journal of infectious diseases, 2017, Mar-24, Volume: 70, Issue:2

    An 87-year-old man with poorly controlled diabetic mellitus presented with fever, bedsores, and elevated hepatobiliary enzyme levels. He was diagnosed with bacteremia with acute cholangitis due to Arthrobacter species, which are Gram-positive, aerobic, catalase-positive, coryneform bacteria belonging to the family Microbacteriaceae. Doripenem and subsequencial sulbactam/ampicillin treatment were used for the acute cholangitis, and the bacteremia was treated with a 2-week course of vancomycin. The bacteremia was misidentified by the phenotyping assay (API Coryne test), but was identified as Arthrobacter creatinolyticus by 16S rRNA and matrix-assisted laser-desorption/ionization time-of-flight mass spectrometry. To our knowledge, this is the first report of a human case of A. creatinolyticus bacteremia.

Pantoea calida bacteremia in an adult with end-stage stomach cancer under inpatient care.
    Journal of infection and chemotherapy : official journal of the Japan Society of Chemotherapy, 2017, Volume: 23, Issue:6

    Pantoea calida is a gram-negative bacillus that was first identified in 2010. Here, we describe the first known case of P. calida bacteremia in a 77-year-old woman with end-stage stomach cancer under inpatient care. The patient was admitted to our hospital for pain after receiving anti-cancer therapy at outpatient facility. Thirteen days after admission, her temperature rose to 39.6 °C. A blood culture was ordered for suspected bacterial infection, and the patient was treated empirically with ampicillin/sulbactam. Cultures showed white pitting colonies later identified as a Pantoea sp. by biochemical analysis. The isolate's 16S rRNA sequence was identical to that of P. calida (100%), and showed 99.1% similarity with that of Pantoea gaviniae. Matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF MS) confirmed the species as P. calida with an average spectral score >2.0. The primary isolate was ampicillin-resistant, but susceptible to other antibiotics and the bacteremia was cleared after three days of antibiotic therapy. Since P. calida infection is relatively rare, limited information exists on the pathogen's portal of entry and bacterial characteristics; thus, further studies are necessary to establish the pathophysiological mechanisms P. calida infection.

Secular trends in Acinetobacter baumannii resistance in respiratory and blood stream specimens in the United States, 2003 to 2012: A survey study.
    Journal of hospital medicine, 2016, Volume: 11, Issue:1

    Acinetobacter baumannii (AB) has evolved a variety of resistance mechanisms and exhibits unpredictable susceptibility patterns, making it difficult to select empiric therapy.. To examine US secular trends in the resistance of AB in respiratory infections and blood stream infections (BSI) to antimicrobial agents whose effectiveness is supported in the literature. Survey.. We analyzed 3 time periods (2003-2005, 2006-2008, 2009-2012) in Eurofins' The Surveillance Network for resistance of AB to the following antimicrobials: carbapenems (imipenem, meropenem, doripenem), aminoglycosides (tobramycin, amikacin), tetracyclines (minocycline, doxycycline), polymyxins (colistin, polymyxin B), ampicillin-sulbactam, and trimethoprim-sulfamethoxazole. Resistance to ≥3 drug classes defined multidrug resistance (MDR).. We identified 39,320 AB specimens (81.1% respiratory, 18.9% BSI). The highest prevalence of resistance was to doripenem (90.3%) followed by trimethoprim-sulfamethoxazole (55.3%), and the lowest to colistin (5.3%). Resistance to carbapenems (21.0% in 2003-2005 and 47.9% in 2009-2012) and colistin (2.8% in 2006-2008 to 6.9% in 2009-2012) more than doubled. Prevalence of MDR AB rose from 21.4% in 2003 to 2005 to 33.7% in 2006 to 2008, and remained stable at 35.2% in 2009 to 2012. In contrast, resistance to minocycline diminished from 56.5% (2003-2005) to 30.5% (2009-2012). MDR organisms were most frequent in nursing homes (46.5%), followed by general ward (29.2%), intensive care unit (28.7%), and outpatient setting (26.2%).. Resistance rates among AB to such last-resort antimicrobials as carbapenems and colistin are on the rise, whereas that to minocycline has declined. Nursing homes are a reservoir of resistant AB. These trends should inform not only empiric treatment of serious infections, but also approaches to infection control.

Late, Late-Onset Group B Streptococcus Cellulitis With Bacteremia.
    Pediatric emergency care, 2016, Volume: 32, Issue:1

    Group B streptococcus (GBS) infection remains a leading cause of serious neonatal and early infantile infection. As the infection often presents with nonspecific symptoms, and is associated with underlying bacteremia, prompt investigation and treatment is required. We report a case of late, late-onset GBS infection with bacteremia in a 94-day-old boy experiencing cellulitis of the left hand. Although late-onset disease or late, late-onset disease has been reported to be common among infants with underlying conditions such as premature birth, immunocompromised status, trauma, or among those using medical devices, no such underlying medical condition predisposed this infant to invasive GBS infection. Recent reports including the present case underscore the risk of GBS infection among previously healthy infants beyond the neonatal period. Thus, clinicians should especially be aware of unusual presentations of GBS invasive disease with bacteremia.

Bacteremia due to Acinetobacter ursingii in infants: Reports of two cases.
    The Pan African medical journal, 2016, Volume: 23

    Acinetobacter ursingii is an aerobic, gram-negative, opportunistic microorganism which is rarely isolated among Acinetobacter species. We present two immunocompetent infants who developed bacteremia due to A. ursingii. The first patient is a two -month- old boy who had been hospitalized in pediatric surgery unit for suspected tracheo-esophageal fistula because of recurrent aspiration pneumonia unresponsive to antibiotic therapy. The second patient is a fourteen -month- old boy with prolonged vomiting and diarrhea. A. ursingii was isolated from their blood cultures. They were successfully treated with ampicillin-sulbactam. Although A. ursingii has recently been isolated from a clinical specimen; reports of infection with A. ursingii in children are rare. A. ursingii should be kept in mind as an opportunistic microorganism in children.

Trends in Susceptibility Rates and Extended-Spectrum β-Lactamase Production of Klebsiella pneumoniae in Bloodstream Infections Across the United States Veterans Affairs Healthcare System.
    Microbial drug resistance (Larchmont, N.Y.), 2015, Volume: 21, Issue:6

    Klebsiella pneumoniae is an important pathogen, increasingly notorious for its ability to become resistant to antimicrobial agents. This study sought to characterize trends in antimicrobial susceptibility rates for K. pneumoniae causing bacteremias across the United States (U.S.) Veterans Healthcare Administration (VHA) from 2007 through 2013 utilizing a national clinical database. K. pneumoniae grew in 9,235 blood cultures from 8,414 patients. Nationally, ampicillin-sulbactam, ceftazidime, cefepime, ertapenem, fluoroquinolones, and amikacin demonstrated statistically significant susceptibility rate increases against K. pneumoniae in the 2010-2013 period versus the 2007-2009 period. No antimicrobial agent had a statistically significant nationwide susceptibility rate decrease. Of the 126 antibiotic-organism pairs tested among 9 U.S. regions, 18 demonstrated statistically significant susceptibility rate increases while 6 demonstrated statistically significant susceptibility rate decreases. The East North Central (eight agents), Mid-Atlantic (five agents), and South Atlantic (four agents) regions demonstrated statistically significant susceptibility rate increases for multiple antimicrobial agents. Of the 70 antibiotic-organism pairs tested among 5 different medical center complexity levels, 11 antibiotics demonstrated statistically significant susceptibility rate increases and 1 demonstrated a statistically significant rate decrease. Extended-spectrum β-lactamase production did not significantly change over the study period across an available nationwide representation of 31 facilities (10.6% in 2007-2009 vs. 9.21% in 2010-2013, p=0.17). The South Atlantic and Mid-Atlantic regions had the highest prevalence of extended-spectrum ß-lactamase production in the two periods, respectively. The recent trend of generally increasing susceptibility rates for K. pneumoniae bloodstream isolates in this nationwide U.S. VHA study contrasts from other U.S. health system reports demonstrating increasing trends of antimicrobial resistance.

Anaerobiospirillum succiniciproducens-induced bacteremia in a healthy man.
    The American journal of emergency medicine, 2014, Volume: 32, Issue:7

    Anaerobiospirillum succiniciproducens is rarely associated with bacteremia but results in significant mortality. Almost all reported bacteremia cases have occurred in immunocompromised hosts, such as those with alcoholic liver disease, atherosclerosis, recent surgery, malignancies, or acquired immunodeficiency syndrome. We describe here, to our knowledge, the first clinical evidence for A succiniciproducens bacteremia in a healthy man. A 61-year-old man had fallen from a roof and was admitted to our emergency department with severe left flank pain without an external wound. He was given transcatheter arterial embolization for the left kidney injury on the same day, and his condition stabilized. Four days after admission, he had fever without gastrointestinal signs and symptoms. Spiral-shaped, gram-negative anaerobic bacteria were isolated from 2 sets of blood cultures, and the oxidase and catalase test results were negative. The isolated bacteria were different from the Campylobacter spp. On the next day, the bacteria were confirmed as A succiniciproducens by 16S rRNA sequencing. The patient responded to sulbactam/ampicillin. On day 13, the patient was discharged with a 7-day prescription for oral amoxicillin/clavulanate. Six months after admission, the patient was free of recurrent infection. A succiniciproducens bacteremia can occur in healthy adults. When large gram-negative spiral-shaped bacteria are detected, this bacterial species should be considered and differentiated from the Campylobacter spp because A succiniciproducens is often resistant to macrolide antibiotics.

[Necrotising endocarditis of mitral valve due to Staphylococcus lugdunensis].
    Mikrobiyoloji bulteni, 2009, Volume: 43, Issue:2

    Staphylococcus lugdunensis is an infrequent cause of infective endocarditis (IE) and usually involves native valves of the heart. It causes life-threatening events such as rupture of cardiac valve or cerebral or pulmonary embolism due to necrosis on the endocardial tissue involved by the bacteria. Antibiotic therapy without cardiac surgery or delayed cardiac surgery usually follows a fatal course in S. lugdunensis endocarditis. In this report the first case of S. lugdunensis endocarditis from Turkey was presented. A 37-year-old man was admitted to the emergency department with a 2-weeks history of fever chills and accompanying intermittent pain on the left side of the thorax. Other than recurrent folliculitis continuing for 20 years, his history was unremarkable. Echocardiography revealed vegetation on the mitral valve of the patient and vancomycin plus gentamicin were initiated with the diagnosis of IE. All blood cultures (5 sets) taken on admission and within the initial 48 hours of the antibiotic therapy yielded S. lugdunensis. According to the susceptibility test results, the antibiotic therapy was switched to ampicillin-sulbactam plus rifampin. Blood cultures became negative after the third day of therapy, however, cardiac failure was emerged due to rupture of mitral valve and chorda tendiniea on the 12th day of the therapy. Cardiac surgery revealed that mitral valve and surrounding tissue of the valve were evidently necrotic and fragile, anterior leaflet of the mitral valve was covered with vegetation, posterior leaflet and chorda tendiniea were ruptured. Vegetation was removed and the destructed mitral valve was replaced with a mechanical valve. Vegetation culture remained sterile, however, antibiotics were switched to vancomycin plus rifampin due to persistent fever on the 21st day of the therapy (9th day of operation). Fever resolved four days after the antibiotic switch. Antibiotics were stopped on the 9th weeks of admission and the patient was discharged. He had no problem in follow-up controls for one year. In conclusion, proper antibiotic therapy combined with early cardiac surgery seems to be the optimal therapeutic approach in IE caused by S. lugdunensis.

    Medizinische Klinik (Munich, Germany : 1983), 2007, Jun-15, Volume: 102, Issue:6

    A case of listeriosis in a patient undergoing long-term hemodialysis is reported. The 69-year-old man with chronic renal failure due to polycystic renal dysplasia had received hemodialysis treatment for 10 years. Renal anemia and iron overload developed within this time. In the course of a hemodialysis the patient presented with malaise, chills and fever to 38.7 degrees C. Blood culture specimens were obtained and the patient received ampicillin-sulbactam. Blood culture specimens subsequently showed growth of Listeria monocytogenes. During therapy the patient improved rapidly and was free from fever on day 5. The relation of iron overload and Listeria infection is discussed.

    Nihon Kokyuki Gakkai zasshi = the journal of the Japanese Respiratory Society, 2004, Volume: 42, Issue:2

    A 56-year-old woman was admitted to our hospital with fever, cough, and sputum production. Her chest radiograph and chest computed tomography showed multiple nodules. Laboratory findings revealed leukocytosis and an increased C-reactive protein concentration. Physical examination revealed a systolic murmur. Transesophageal echocardiography demonstrated a 1.5-cm area of vegetation on the tricuspid valve. Blood cultures grew Staphylococcus aureus. Tricuspid valve endocarditis and septic pulmonary embolism were diagnosed. She was treated successfully with intravenous ampicillin/sulbactam. This was a rare case of tricuspid valve infective endocarditis in an adult patient without known predisposing factors.

Epidemiology, resistance, and outcomes of Acinetobacter baumannii bacteremia treated with imipenem-cilastatin or ampicillin-sulbactam.
    Pharmacotherapy, 2001, Volume: 21, Issue:2

    To evaluate epidemiology, resistance, and treatment outcomes of Acinetobacter baumannii bacteremia treated with imipenem-cilastatin or ampicillin-sulbactam for 72 hours or longer.. Retrospective analysis.. University teaching hospital.. Forty-eight patients with A. baumannii bacteremia.. Evaluation of susceptibility and clinical data from 48 patients treated with either ampicillin-sulbactam or imipenem-cilastatin from 1987-1999.. Comparing ampicillin-sulbactam and imipenem-cilastatin, there were no differences between days of bacteremia (4 vs 2 days, p=0.05), days to resolution of temperature or white blood cell count, success or failure during or at end of treatment, or intensive care unit total or antibiotic-related length of stay (13 vs 10 days, p=0.05). Patients treated with ampicillin-sulbactam had significantly decreased antibiotic treatment costs (1500 dollars vs 500 dollars, p=0.004).. Ampicillin-sulbactam is at least as effective as imipenem-cilastatin based on clinical response at days 2, 7, and end of treatment and is a cost-effective alternative for treatment of A. baumannii infections.

Group F streptococcal bacteremia complicating a Bartholin's abscess.
    Infectious diseases in obstetrics and gynecology, 2001, Volume: 9, Issue:1

    Group F streptococci are gram-positive cocci typically isolated from wound infections and abscesses. Bacteremia with group F streptococcus is uncommon, and the lower gynecologic tract has not been reported as a source. We report a case of a Bartholin's abscess leading to group F streptococcal bacteremia.. A 31-year-old female noted fever and rigors 30 min after manipulation of a 3-day-old vulvar abscess. An empty Bartholin's gland abscess was found on examination, and blood cultures grew beta-hemolytic group F streptococci. The patient was treated with ampicillin/sulbactam, symptoms improved, and follow-up blood cultures revealed no growth.. Group F streptococci are known to inhabit various body sites and have a predilection for forming abscesses; however, bacteremia is infrequent. They have occasionally been identified in true infections of the genitourinary tract but only very rarely in Bartholin's abscesses. This case of group F streptococcal bacteremia following self-drainage of a Bartholin's abscess constitutes the first such description in the medical literature.

Efficacy of ampicillin-sulbactam is not dependent upon maintenance of a critical ratio between components: sulbactam pharmacokinetics in pharmacodynamic interactions.
    Antimicrobial agents and chemotherapy, 1996, Volume: 40, Issue:11

    An in vitro pharmacokinetic model (IVPM) and a mouse model of lethal bacteremia were used to compare the pharmacodynamics of ampicillin-sulbactam when the two components were dosed simultaneously and in sequence against TEM-1-producing Escherichia coli. The challenge isolates included three strains of E. coli producing various levels of beta-lactamase. Human pharmacokinetics of ampicillin-sulbactam (1.5- and 3.0-g intravenous doses) were simulated in each model, and pharmacodynamic interactions were evaluated over one 6-h dosing interval. Against all three strains, the sequential dosing of sulbactam prior to ampicillin did not alter the pharmacodynamics of these combinations from comparison with results obtained with the simultaneous administration of the two components. Similar pharmacodynamics were observed for the two dosing regimens regardless of the ampicillin-sulbactam dose used or whether the bacteria were treated in an immunocompetent mouse or in the absence of immune defenses in the IVPM. When antibacterial activity was lost and regrowth of the inoculum was observed, viable bacterial counts increased in both the simultaneous and sequential regimens at a point when sulbactam levels fell below a critical concentration. These data suggest that the efficacy of ampicillin-sulbactam is not dependent upon the maintenance of a constant 2:1 ratio for the two components. Rather, the efficacy of ampicillin-sulbactam appears to be dependent upon the maintenance of one or both components above a critical concentration. Furthermore, the pharmacokinetics of sulbactam, specifically, how long sulbactam levels remain above a minimum critical concentration, appears to dictate how long antibacterial activity is maintained with the combination.

Comparison of ampicillin-sulbactam regimens simulating 1.5- and 3.0-gram doses to humans in treatment of Escherichia coli bacteremia in mice.
    Antimicrobial agents and chemotherapy, 1995, Volume: 39, Issue:4

    A mouse model of bacteremia was used to compare the efficacies of 1.5- and 3.0-g intravenous doses of ampicillin-sulbactam. Seven strains of Escherichia coli producing various levels of TEM-1 beta-lactamase were used as the challenge isolates. These strains included six clinical isolates (MICs from 2/1 micrograms/ml [with 2 and 1 microgram/ml being the respective concentrations of ampicillin and sulbactam] to 32/16 micrograms/ml) with similar degrees of virulence in mice and a laboratory genetic transformant (E. coli AFE) which hyperproduces TEM-1 (MIC = 128/64 micrograms/ml). Human pharmacokinetics were simulated by injecting mice subcutaneously twice (1 h apart) with ampicillin-sulbactam at concentrations of 40 mg/kg of body weight (1.5 g) and 80 mg/kg (3.0 g). Against two clinical isolates for which ampicillin-sulbactam MICs were < or = 8/4 micrograms/ml, no difference was observed in either the rate or level of killing between the two doses, and both doses were 100% protective against lethal infection. Against the four clinical isolates for which ampicillin-sulbactam MICs were between 16/8 and 32/16 micrograms/ml, a slight delay in killing was noted with three of the strains. This delay was followed by a rapid 2- to 3-log drop in the level of bacteremia, and both doses of ampicillin-sulbactam were 100% protective against lethal septicemia. With strain AFE, no killing was observed with the 40-mg/kg dose compared with a 2-log killing with the 80-mg/kg dose. This difference in killing correlated with a decreased protective efficacy of the 40-mg/kg dose. These data suggest that the 1.5-g preparation of ampicillin-sulbactam is as effective as the 3.0-g dose in the treatment of experimentally induced E. coli bacteremia, as long as ampicillin-sulbactam MICs are 32/16 micrograms/ml or less.

Improved survival in simulated surgical infection with combined cytokine, antibiotic and immunostimulant therapy.
    The British journal of surgery, 1994, Volume: 81, Issue:9

    A study was performed to find an ideal combination and sequence of cytokines, antibiotics and immunorestorative agents to enhance survival from serious infection. The effects of combinations of granulocyte-macrophage colony-stimulating factor (GM-CSF), tumour necrosis factor (TNF) alpha, the immune adjuvant muramyl dipeptide (MDP) and two systemic antibiotics were studied in a validated murine model of surgical infection. A single cotton suture containing absorbed Klebsiella pneumoniae was placed into the thighs of mice to produce local and systemic infection. Control mice received a volume of subcutaneous saline equal to that of the therapeutic agent; only 18 per cent survived 9 days after infection. The survival time of mice treated with any single agent was similar to that of controls. The group given maximal combined therapy (65 mice) received GM-CSF, TNF-alpha, MDP, and ampicillin-sulbactam or cefoxitin for 6 days. The survival rate in this group 9 days after the introduction of infection was 84-90 per cent (P < 0.0001), suggesting that specific combinations of cytokines, immunostimulants and antibiotics may be useful in combating lethal infection.

Antibacterial effects of ofloxacin, clindamycin and sultamicillin on surgical removal of impacted third molars.
    Journal of Marmara University Dental Faculty, 1992, Volume: 1, Issue:3

    This study examined the bacteraemia following surgical removal of impacted mandibular third molars and evaluated the antibacterial effects of Ofloxacin, Clindamycin, Sultamicillin, used as prophylactic medications. The study involved a hundred healthy patients whose mandibular third molars were impacted horizontally. These patients were divided into four groups each including 25 individuals. One of the four groups was the control group. The other groups were those to which Ofloxacin, Clindamycin, and Sultamicillin were administered one hour before the operation and in the following 4 days postoperatively. Blood samples were taken before and immediately after the operation, and then, 1 and 24 hours postoperatively. Following the incubation of the samples under aerobic and anaerobic conditions, the samples were examined microbiologically. Preoperative samples were found to be negative. In the immediate postoperative samples, bacteraemia was found in 44% of the control group, 40% of Ofloxacin and Clindamycin groups and 36% of the Sultamicillin group. In the samples taken 1 hour after the operation, bacteraemia was found in 28% of the control group, 20% of the Ofloxacin group and 24% of the Clindamycin and Sultamicillin groups. In the control group, only 2 cases showed positive culture in the blood samples taken 24 hours after the operation. In conclusion, the antibiotics, Ofloxacin, Clindamycin, Sultamicillin have a significant effect in decreasing the risk of postoperative infection and bacteraemia.
