Biotic transformation of anticoccidials in soil using a lab-scale bio-reactor as a precursor-tool.
    Chemosphere, 2012, Volume: 86, Issue:2

    Two anticoccidial agents, salinomycin and robenidine, heavily used in the worldwide veterinary meat production, were investigated for their potential biotic degradation by cultured soil bacteria. The degradation-study was performed in lab-scale bio-reactors under aerobic and anaerobic conditions incubated for 200 h with a mixed culture of soil bacteria. Samples were analyzed by LC-MS/MS and potential transformation products were tentatively identified. Salinomycin was degraded under aerobic conditions and traces could be found after 200 h, however, seems more persistent under anaerobic conditions. Four transformation products of salinomycin were discovered. Robenidine was degraded under aerobic and anaerobic conditions, however, traces of robenidine were observed after 200 h. Five biotic transformation products of robenidine were discovered.

In vitro destruction of Eimeria oocysts by essential oils.
    Veterinary parasitology, 2011, Dec-15, Volume: 182, Issue:2-4

    This study aims to assess the ability of essential oils (EOs) to destroy Eimeria oocyst in vitro using microscopic counting and 273 nm absorbing material release. A screening for the ability of ten EOs to destroy Eimeria oocyst was carried out in liquid medium. Out of these ten, artemisia, tea tree, thyme and clove EOs were identified as being the most effective. The treatment of Eimeria oocyst with these EOs leads to their lysis as shown by the release of substances absorbing at 273 nm. These results were obtained after approximately three hours contact. Four EOs were proven to destroy Eimeria oocysts in a few hours at low concentration. This destructive effect is a consequence of their lysis. This work is a preliminary contribution aiming to develop a new generation of natural efficient agents for destroying Eimeria oocyst to fight coccidiosis in broiler chicken.

Fate and antibacterial potency of anticoccidial drugs and their main abiotic degradation products.
    Environmental pollution (Barking, Essex : 1987), 2009, Volume: 157, Issue:2

    The antibacterial potency of eight anticoccidial drugs was tested in a soil bacteria bioassay (pour plate method), EC(50)-values between 2.4 and 19.6 microM were obtained; however, one compound, nicarbazin exhibited an EC(50)-value above the maximum tested concentration (21 microM, 9.1 mg L(-1)). The potency of mixtures of two of the compounds, narasin and nicarbazin, was synergistic (more than additive) with 10-fold greater antibacterial potency of the mixture than can be explained by their individual EC(50)-values. The influence of pH, temperature, oxygen concentration and light on the transformation of robenidine and salinomycin was investigated. Robenidine was transformed by photolysis (DT(50) of 4.1 days) and was unstable at low pH (DT(50) of approximately 4 days); salinomycin was merely transformed at low pH, the latter into an unknown number of products. The antibacterial potency of the mixtures of transformation products of robenidine after photolysis and at low pH was comparable with that of the parent compound. Finally five photo-transformation products of robenidine were structural elucidated by accurate mass measurements, i-FIT values (isotopic pattern fit) and MS/MS fragmentation patterns.

Studies of resistance to anticoccidials in Eimeria field isolates and pure Eimeria strains.
    Veterinary parasitology, 1997, Volume: 69, Issue:1-2

    Ten Eimeria field isolates from North Germany were studied in battery tests for sensitivity to selected anticoccidials. A high percentage of the Eimeria field isolates (9 out of 10) showed resistance to anticoccidials, mostly multiple resistance. Partial or complete resistance to maduramicin was found in 7 field isolates, to monensin in 6, to salinomycin in 5, to nicarbazin in 8, to halofuginone in 7, to robenidine and toltrazuril in 1, and to diclazuril in 2 field isolates. Multiple resistance had developed in 7 of the 10 isolates. Cross-resistance between maduramicin, monensin, and salinomycin occurred in 5 Eimeria isolates. One isolate showed cross-resistance between diclazuril and toltrazuril. From the resistant isolates 15 pure E. acerculina and 5 pure E. brunetti strains were obtained by single oocyst infections. Seven of the E. acerculina and 4 of the E. brunetti strains showed resistance or partial resistance that was also present in the original isolate. Ten of 11 resistant strains were multiply resistant.

Fetotoxicity of some anticoccidial drugs in chickens.
    DTW. Deutsche tierarztliche Wochenschrift, 1989, Volume: 96, Issue:6

    Fetotoxic effects induced by three anticoccidial drugs: robenidine, salinomycin and arprinocid were elucidated in the chicken. Different doses of these drugs were inoculated in groups of embryonated chicken eggs by the yolk sac route. After inoculation, candling of the eggs was performed daily and embryonic or fetal mortalities were recorded. At 19 days old, alive fetuses were collected, weighed, measured and examined morphologically for abnormalities. A group of eggs was kept non-inoculated as a control and another was inoculated with the solvent of the tested drugs. Inoculation of 0.09-9.75 mg robenidine/egg, 0.06-6.75 mg salinomycin/egg or 0.08-8.25 mg arprinocid/egg into the yolk sac of 7 days old embryos caused a dose-dependent fetal death. Arprinocid was the most lethal to chicken fetuses, followed by salinomycin while robenidine was the least. Dead fetuses were usually haemorrhagic, dwarfish and friable. Surviving fetuses showed a dose-dependent reduction in body weight and length, insignificant decrease in leg and wing lengths as well as some developmental abnormalities.
