İnek sütlerinde Listeria türlerinin varlığı ve antibiyotik direnci ile aerobik mezofilik bakteri sayısının belirlenmesi

Listeria species lead to mastitis infection in cows. The aerobic mesophilic bacteria count (total count) is one of the most important factors affecting udder health and determining milk quality. aim this study was determine count, cow's quality, presence antibiotic resistance profiles spp., causing As a result isolation identification for totally 3 L. monocytogenes (n: 68, 4.41%), 7 innocua 10.29%) ivanovii 4.41%) were isolated from cow samples. According results disc diffusion method performed susceptibility, it found that monocytogenes, innocua, isolates susceptive against sulfamethoxazole/ trimethoprim, meropenem, vancomycin, streptomycin, oxacillin erythromycin. samples detected 1.1x107 cfu/ml as highest 2.3x102 lowest. average calculated 256623.971 cfu/ml. total (aerobic bacteria) (cfu/ml) be high based on criteria stated national international standards. Also, these Since intermediate resistant determined antibiotics used treatment option isolates, thought should also considered infections terms etiology treatment. It control program needed preventing development economic losses dairy cattle enterprises order provide milking hygiene completely.
