Viral Infections of Domestic Animals.

Mastitis is the most economically significant disease of dairy animals

s: In the present study, 20 samples of milk of cow, pasteurized milk were collected from the local market and were analyzed for microbial count and IMViC tests to determine the coliform load in the sample. Further, the presence of E. coli (KC795687) was confirmed by using PCR and 16srna sequencing. Majority of the milk samples of different origin were found to be contaminated by the coliform gr...

Enteric Infections in Man and Animals: Standardization of Immunological Procedures

The protective effect of a combined rotavirus/enterotoxigenic E. coli K99 vac­ cine against naturally occurring neonatal diarrhoea was evaluated in two dairy and two beef herds. Before vaccination, frequency of diarrhoea in these herds was 46% up to 60% with losses of 7% to 20%. After vaccination of pregnant cows and heifers mild diarrhoea occurred in 14% to 20% of their calves, one out of 144 ...
