One hundred and seventy four (39.2%) from 82 cattle (73.9%) were found to infected with mastitis. It was found that 8(1.8%) of the infected quarters were clinical mastitis and all of the rest were subclinical mastitis. 3. The main causative agents were found to Staphylococcus aureus (63 quarters), Streptococcus agalactiae (56 quarters), non-Str. agalactiae streptococci (54 querters), Escherichia coli (19 quaters), the actual total number of quarters detected as mastitis would be 174, as 18 of these quarters showed multiple infection with two different organisms. 4.
