Protection of day-old poults against Arizona hinshawii challenge by preincubation streptomycin egg treatment.
Poults were protected against challenge with Arizona hinshawii 7:1,7,8 inoculated into the yolk sac 30 hours post-hatching by preincubation streptomycin treatment of turkey eggs, administered by temperature-differential egg dipping in a solution composed of 250 ppm of a quaternary ammonium compound, 10 ppm of ethylenediaminetraacetate and streptomycin at 9 mg per ml. Mortalities at 17 hours and 22 days postchallenge were respectively 8% and 44% in poults from treated eggs vs 47% and 93% from untreated eggs. Liver isolation rates at 17 hours and 22 days postchallenge were respectively 0% and 16% in poults from treated eggs, vs 71% and 80% from untreated eggs.
