Abstract:
Calf diarrhea is one of the major health challenges in cattle herds. Escherichia coli is the most common cause of calf diarrhea. In the current study, we isolated a total of 27 isolates from diarrheic calves. The preliminary identification was carried out by the development of a green metallic sheen on the Eosin Methylene Blue agar plate. After that molecular level confirmation by amplification of 16S rRNA gene. The positive isolates were subjected to phylogroups. The B1 and A were most prevalent while phylogroup C, D, and E were less likely to be associated with calf diarrhea.
