some serum acute phase proteins and immunoglobulins concentrations in calves with rotavirus, coronavirus, e. coli f5 and eimeria species

the purpose of this study was to evaluate the changes in the serum concentrations of haptoglobin (hp), serum amyloid a (saa) and igg, iga in calves with diarrhea caused by rotavirus, coronavirus, escherichia coli f5 and eimeria species. the experiment was carried out on 40 diarrhoeic and 10 non-diarrhoeic calves (group c). a total of 13 calves were infected with rotavirus or coronavirus (group v), 12 calves with e. coli f5 (group b) and 15 calves with eimeria species (group p). saa and hp levels of calves in groups v, b and p were statistically higher than group c (p
