Treatment of imported fire ant stings with mitigator sting and bite treatment--a randomized control study.
To evaluate the efficacy of the commercially available product Mitigator Sting and Bite Treatment in reducing the pain after imported fire ant stings.. Twenty-four volunteer subjects were exposed to imported fire ant stings on both fore-arms. The subjects received Mitigator paste on 1 arm and calamine lotion on the opposite arm, in a blinded manner, from 90 seconds to 10 minutes after exposure. Subjects recorded pain on a 100-mm visual analog scale 60 seconds, 20 minutes, and 3 days after exposure. A 2-tailed paired t test was used to compare the difference in reduction of pain over time between the Mitigator-treated arms and the calamine-treated arms.. At 60 seconds, the mean visual analog scale pain score was 23.9 mm for the Mitigator group and 24.5 mm for the calamine group. At 20 minutes, the mean score was 7.6 mm (delta = 16.3) for the Mitigator group and 12.7 mm (delta = 11.8) for the calamine group. At 3 days, the mean score was 2.4 mm (delta = 21.5) for the Mitigator group and 2.9 mm (delta = 21.6) for the calamine group. There was no significant difference between groups for change in visual analog scale pain score at 60 seconds, 20 minutes (P = .256), or 3 days (P = .64).. There was no significant difference in pain relief between calamine and Mitigator for imported fire ant stings.

Ant venoms contain vertebrate-selective pain-causing sodium channel toxins.
Stings of certain ant species (Hymenoptera: Formicidae) can cause intense, long-lasting nociception. Here we show that the major contributors to these symptoms are venom peptides that modulate the activity of voltage-gated sodium (Na Topics: Animals; Ant Venoms; Ants; Pain; Sodium Channels; Toxins, Biological; Vertebrates | 2023 |
The development of Jack Jumper ant venom immunotherapy: our 25 years' experience.
Jack Jumper ant venom allergy is a uniquely Australian medical issue. The stinging ant is a leading cause of insect venom allergy in south-eastern Australia. An effective venom immunotherapy-based treatment was successfully developed by the Tasmanian Jack Jumper Allergy Research group. This paper provides a synopsis of our 25 years' research journey in developing this evidence-based treatment modality.

[A CASE OF ANAPHYLAXIS DUE TO STINGING OF A Brachyponera chinensis].
The case involved a man in his forties. While working at the restaurant that the patient runs, the patient experienced a stab-like pain on the left shoulder and developed systemic pruritic eruptions. He was diagnosed with anaphylaxis upon visiting our emergency department. Conjunctival hyperemia, lip swelling, cold sweats, and nausea presented later. A cap fluorescence enzyme immunoassay using the serum of the patient showed specific immunoglobulin E (IgE) positivity for wasps; therefore, we hypothesized that he had anaphylaxis caused by the insect's sting. Insects of the same species as that by which the patient had been stung were collected and finally identified as the Asian needle ant (Brachyponera chinensis). The freeze-dried insects' bodies were sonicated into powders and stored for following examinations. Next, a basophil activation test was performed using the patient's whole blood treated with the reagent above, which showed positivity. Furthermore, a skin prick test using the same reagent showed a positive result, and the reaction increased in a concentrationdependent manner. Based on these results, the patient was diagnosed with anaphylaxis after a sting by the ant. Based on the results of the allergen component specific IgE test, we speculated that the pathogens in this case was group5 allergen of the Asian needle ant. Anaphylaxis following insect stings by this ant has been reported frequently in South Korea. However, it is quite rare in Japan, although the ant is native to Japan. Clinicians should consider that this allergy can occur indoors, unlike allergies to other types of venom.

Pain and Lethality Induced by Insect Stings: An Exploratory and Correlational Study.
Pain is a natural bioassay for detecting and quantifying biological activities of venoms. The painfulness of stings delivered by ants, wasps, and bees can be easily measured in the field or lab using the stinging insect pain scale that rates the pain intensity from 1 to 4, with 1 being minor pain, and 4 being extreme, debilitating, excruciating pain. The painfulness of stings of 96 species of stinging insects and the lethalities of the venoms of 90 species was determined and utilized for pinpointing future directions for investigating venoms having pharmaceutically active principles that could benefit humanity. The findings suggest several under- or unexplored insect venoms worthy of future investigations, including: those that have exceedingly painful venoms, yet with extremely low lethality-tarantula hawk wasps ( Topics: Animals; Ants; Arthropod Venoms; Bees; Female; Humans; Insect Bites and Stings; Lethal Dose 50; Male; Mice, Inbred ICR; Pain; Social Behavior; Wasps | 2019 |
Δ-Myrtoxin-Mp1a is a Helical Heterodimer from the Venom of the Jack Jumper Ant that has Antimicrobial, Membrane-Disrupting, and Nociceptive Activities.
Δ-Myrtoxin-Mp1a (Mp1a), a 49-residue heterodimeric peptide from the venom of Myrmecia pilosula, comprises a 26-mer A chain and a 23-mer B chain connected by two disulfide bonds in an antiparallel arrangement. Combination of the individual synthetic chains through aerial oxidation remarkably resulted in the self-assembly of Mp1a as a homogenous product without the need for directed disulfide-bond formation. NMR analysis revealed a well-defined, unique structure containing an antiparallel α-helix pair. Dual polarization interferometry (DPI) analysis showed strong interaction with supported lipid bilayers and insertion within the bilayers. Mp1a caused non-specific Ca Topics: Acinetobacter baumannii; Animals; Anti-Bacterial Agents; Ants; Calcium; Cell Line, Tumor; Dose-Response Relationship, Drug; Humans; Hyperalgesia; Mice; Microbial Sensitivity Tests; Models, Molecular; Pain; Peptides; Venoms | 2017 |
Venom's antinociceptive property in the primitive ant Dinoponera quadriceps.
In northeastern Brazil, Dinoponera (Ponerinae) ants macerate are used to treat ear ache and its sting, rheumatism, and back pain. Such a popular use is a relevant fact that called for experimental evaluation of the antinociceptive activity of Dinoponera venom.. Dinoponera quadriceps venom (DqV; 5-500 μg/kg; i.v.) or morphine (3.4 mg/kg; s.c.) were evaluated in mice models of nociception (n=8 animals/group). Negative controls received sterile saline (0.9% NaCl; i.v.).. DqV showed 64% protein content and exhibited antinociceptive activity, without affecting motor function, in the tests: formalin (72%), writhing (52%), von Frey (71%) and hot plate (45%). The antinociceptive activity was abolished under protein denaturant conditions.. This study provided the first demonstration of the antinociceptive property of Dinoponera quadriceps venom in mice models of chemical, mechanical and thermal nociception, corroborating the popular use and suggesting its potential therapeutic utilization in painful conditions.
