Studies of resistance to anticoccidials in Eimeria field isolates and pure Eimeria strains.
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.

Control of a line of E. tenella, partly resistant to monensin, by including toltrazuril discontinuously in the drinking water of chickens.
Discontinuous medication with toltrazuril, given in the drinking water at a concentration of 50 ppm, was effective in controlling infection resulting from repeated inoculation of oocysts of a line of E. tenella partly resistant to monensin. Treatment was very effective when the drug was given for periods of 3 days, on two or three occasions at weekly intervals. Monensin, at a concentration of 120 ppm, given continuously in the feed was only partially effective. Following treatment with toltrazuril, birds inoculated with high doses of oocysts were immune to subsequent challenge. It is suggested that discontinuous medication with toltrazuril in the drinking water might provide an alternative to the current practice of incorporating drugs continuously in the feed.
