Efficacy of some drugs on calves diarrhoea cased by e coli

Bacteriological examination of faecal swabs obtained from newlyborn buffaloe calves [7 days to one month of age] suffering from diarrhea, E.coli was isolated from all samples. Serological identification revealed that the isolated strains were grouped into serotypes O[26], O[55], O[78], O[86], O[101], O[111] O[114], O[119], O[124], O[125], O[126], O[127], and O[142]. Calves with higher serum immune globulins concentration survived, while thoset of known low serum immune globulins concentration showed no beneficial effects from using chloramphenicol or furazolidon in the prevention of deaths from E.coli diarrhea
