abstract
A one month old cattle calf was presented at Veterinary Clinical Complex, Apollo College of Veterinary Medicine, Jaipur with the history of watery feces, depression and inappatance since two days. Detailed physical examination revealed dehydrated skin, sunken eye, tachycardia, tachypnea and slight hypothermia. Fecal sample was collected and sent to department of microbiology for bacteriological culture which showed the presence of E. coli. Whole blood and serum sample were also collected for hematological, biochemical and electrolyte evaluation of calf suffering with diarrhea. On the basis of history, clinical symptoms and microbiological examination the case was diagnosed as E. coli induced diarrhea and treated with parental administration of gentamicin (3mg/kg body weight) and intravenous fluid therapy (Ringer’s Lactate solution). Unevenfull recovery was observed after four days of continuous treatment.
