Abstract
Escherichia coli isolated from udder with acute mastitis were identified biochemically and serologically. The bacteria were then tested for mannose haemagglutination, enterotoxin production, serum resistance and invasivness, characteristics normally associated with Escherichia coli isolated from calves with enteric syndromes. Escherichia coli from the udder were serologically heterogeneous group without the characteristics that are usually correlated with Escherichia coli of intestinal origin.File in questo prodotto:
