Microbiological studies were carried out on 634 milk specimens collected aseptically from mammary gland quarters that had reacted positively to quick diagnostic tests for mastitis (Bernburg or Manu-Test, Alpha-Laval Agri). Causative microorganisms were isolated from 69.72% of the samples. Most of the microorganisms are Gram-positive staphylococci, mainly S. aureus (58,37%) and streptococci (11,54%) and also corynobacteriae (3,85%), Ps. aeroginosa (2,71%) and others (4,75%). In 18,78% of the cases the subclinical mastitis was caused by mixed infections in which two microorganisms participate, mostly staphylococci and streptococci. Str. agalactiae has not been isolated so far in the country as a causative agent of mastitis in buffaloes.
