Abstract:

Mastitis is a disease of production which is caused by a wide range of pathogens that can induce inflammation of the mammary tissues. A cross sectional study was conducted to detect and profile antimicrobial resistance pattern of Staphylococcus aurous in cases of subclinical mastitis. A total of 94 lactating cows were examined using California mastitis test (CMT) and 58.5% were positive for mastitis infection, 25.45% of cultured milk samples contained S. aurous. The antibiotic sensitivity test showed that the highest susceptibility profile was recorded for Tetracycline (92.86%) and gentamycin (92.85%) whereas the highest resistance profile was recorded against sulfamethoxazole trimethoprim (71.42%) and penicillin G (57.15%). On the other hand, 35.72.0% and 28.57% of the isolates, respectively, carried multiple antibiotic resistance phenotypes against TE*PG*ER*SMT and TE*PG* ER*SMT*GE. The findings of this study indicated that antibiotics were imprudently used in the dairy farm which resulted in the emergence of antimicrobial resistant strains. In conclusion, further studies are required to elucidate search of alternative antimicrobials and their effect on the induction and spread of resistant genes as well as standardization of therapeutic uses of antimicrobials, which ensures the right choice and use of drugs locally in the dairy farms.
