Cyathostome ova develop to infective third-stage larvae (L3) at a rate that is directly proportional
Serum proteins were evaluated by agarose electrophoresis at periodic intervals between postinoculation days (PID) 2 and 35 in 4 litters of pigs inoculated orally at 36 to 38 hours of age with 70,000 sporulated Isospora suis oocysts and in 4 litters of age-matched noninoculated control pigs. In
