Antimicrobial susceptibility of Streptococcus species isolated from clinical mastitis in dairy cows

International Journal of Antimicrobial Agents
V Guérin-FaubléeG Carret

Abstract

The antimicrobial susceptibility was determined for 50 Streptococcus uberis, 42 S. dysgalactiae subsp. dysgalactiae and eight S. agalactiae strains isolated from cow mastitis. Only 27% of the strains were susceptible to all antimicrobial compounds tested. Resistance to tetracycline was most frequent (particularly for S. dysgalactiae strains), then macrolide and/or lincomycin resistance. High level resistance to streptomycin and kanamycin was detected. All S. dysgalactiae and S. agalactiae strains were susceptible to beta-lactams but 44% of the S. uberis strains showed an elevated penicillin G MIC. All strains were susceptible to chloramphenicol and rifampicin.

Antimicrobial Resistance

Antimicrobial resistance poses a significant threat to the continued successful use of antimicrobial agents for the treatment of bacterial infections.

Antifungals (ASM)

An antifungal, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis, cryptococcal meningitis, and others. Discover the latest research on antifungals here.

Aminoglycosides

Aminoglycoside is a medicinal and bacteriologic category of traditional Gram-negative antibacterial medications that inhibit protein synthesis and contain as a portion of the molecule an amino-modified glycoside. Discover the latest research on aminoglycoside here.
