Bacterial analyses of 235 milk samples of dairy cattle distributed over 10 farms in Northeastern Algeria, affected by subclinical mastitis diagnosed by the California mastitis test, were carried out over a two-year period (2008-10). Bacterial isolation concerned 80% of the samples. Among the pathogenic agents detected, Gram-positive cocci were the most frequently found, particularly coagulase-negative staphylococci (43%) and Staphylococcus aureus (30%). Escherichia coli was isolated in 14% of the samples. The other bacteria isolated were Streptococcus uberis (4%), Streptococcus agalactiae (3%), Streptococcus dysgalactiae (3%), and more rarely Klebsiella sp. (2%).Downloads
