Abstract: The objective of this study was to recognize the bacteria
involved in bovine subclinical mastitis and their resistance to selected antimicrobial
agents. For this, 100 cows from 15 herds of Algerian center were randomly allocated
and screened by the CMT (California Mastitis Test). The positive samples were
analyzed by conventional bacteriological and Speed Mam®
Color and tested for antimicrobial resistance of bacteria isolated. Bacteriological
analysis shows that there is a wide range of germs that cause mastitis with
40% of Staphylococci aurus, 12% of Streptococci sp., 4% of Enterobacteriaceae,
4% of Pseudomonas sp., 12% for the association Staphylococci aureus+Streptococci
sp., 8% for the association Streptococci sp.+E. coli, 8% for the
association Staphylococci aureus+E. coli, 4% for the association Staphylococci
aureus+Mycoplasma sp. and 4% for the association Staphylococci aureus+Streptococci
sp.+E. coli (or contamination). Sensitivity tests were applied to different
isolated strains and reveals the existence of resistance to antibiotics tested
with varying proportions goal. However, no resistance of these organisms is
noted for the danofloxacin and the association Amoxicillin+Clavulanic acid.
This association of antibiotics would be the treatment of choice of the mastitis.
