Identification and Antimicrobial Susceptibility of Subclinical Mastitis Pathogens Isolated from Hair Goats’ Milk

Authors : Ibrahim Aydin , Kursat Kav and Haci Ahmet Celik

Abstract: Aim of this study, was to identify the pathogens responsible for subclinical mastitis in hair goats and to determine their susceptibility to antimicrobial drugs. Total 700 milk samples from clinically healthy half udders of 350 lactating hair goats were collected and examined. The isolates were identified by conventional methods. Antibiotic susceptibility test was performed using disk diffusion method. Of the 700 milk samples examined, 60 (8.6%) were subclinically infected. Coagulase Negative Staphylococci (CNS), Streptococcus sp. and Staphylococcus aureus were the main species of microorganisms isolated. The CNS were the most common pathogen in this study with an prevalence of 50%. CNS were generally resistant to lactam antibiotics, while S. aureus and Streptococcus sp. were susceptible to lactams. Although, CNS and S. aureus were susceptible to aminoglycosides, fluoroquinolones, erythromycin, sulphamethoxazole/trimethoprim, lincomycin, oxytetracycline and florfenicol, Streptococcus sp. were susceptible to lactams, aminoglycosides, sulphamethoxazole/trimethoprim, erythromycin, oxytetracycline and florfenicol. As results, it may be stated that antimicrobial drug susceptibility tests in subclinical mastitis of the hair goats should be done before the treatments.
