Subklinik mastitisli keçi sütlerinden aerobik bakterilerin izolasyonu

Abstract

Bu çalışmada, 148 adet subklinik mastitisli keçi sütü örneğinden aerobik bakteri izolasyonu amaçlandı. Konvansiyonel yöntemlere göre yapılan değerlendirmede, örneklerin 69’undan (%46.6) aerobik bir bakteri izole edilirken, 79’undan (%53.4) ise her hangi bir bakteri üremesi olmadı. Kültür pozitif örneklerin 42’sinden (%60.8) koagulaz negatif stafilokoklar (KNS), 11’inden (%15.9) Staphylococcus aureus, 11’inden (%15.9) Escherichia coli, 2’sinden (%2.9) Corynebacterium spp., 1’inden (%1.4) Streptococcus spp., 1’inden (%1.4) C. pseudotuberculosis ve 1’inden (%1.4) ise Aeromonas spp. izole edildi. Sonuç olarak, subklinik mastitisli keçi sütlerinden en yüksek oranda KNS izole edildi.

In this study, it was aimed to detect the aerobic bacteria from the goat milk with subclinical mastitis. Milk samples were obtained from the 148 goats and the samples were investigated by classical bacteriological culture methods. Bacteriological cultures were positive in 69 (46.6%) of 148 samples. Bacterial strains isolated from the milk samples were 42 (60.8%) coagulase negative staphylococci (CNS), 11 (15.9%) Staphylococcus aureus, 11 (15.9%) Escherichia coli, 2 (2.9%) Corynebacterium spp., 1 (1.4%) Streptococcus spp., 1 (1.4%) C. pseudotuberculosis and 1 (1.4%) Aeromonas spp. In conclusion, CNS is the most frequently isolated bacterium from the goat milk with subclinical mastitis.
