Özet
Bu çalışmada, Kırıkkale merkez ve ilçelerinde bulunan ineklerde, subklinik mastitis olgularının prevalansının belirlenmesi, mastitise neden olan etkenlerin izolasyonu, identifikasyonu ve bunların antibiyotik direnç durumlarının saptanması amaçlandı. Çalışma kapsamında, 629 sağmal inekten alınan sütler California Mastitis Testi (CMT) ile muayene edildi. CMT pozitif bulunan 342 (%54.37) inekten alınan 836 adet süt örneğinin mikrobiyolojik olarak incelenmesi sonucunda 213’ünde (%25.47) etken izole edildi. İzole edilen etkenler Staphylococcus aureus (%28.17), Staphylococcus haemolyticus (%12.21), Staphylococcus simulans (%8.92), Streptococcus uberis (%8.45), Staphylococcus hominis (%4.22), Staphylococcus capitis (%3.75), Bacillus subtilis (%2.82) ve Mycoplasma spp. (%2.82) şeklinde sıralandı. İzole edilen tüm mikroorganizmalarda, en fazla direnç gözlenen antibiyotik kloksasilin oldu. Staphylococcus aureus ve koagulaz negatif stafilokoklarda (KNS) penisiline, streptokoklarda ise eritromisine karşı direnç ikinci sırada yer aldı. Vankomisine karşı herhangi bir direnç tespit edilmedi. Sonuç olarak; Kırıkkale’de Staphylococcus aureus’a bağlı subklinik mastitis oranının yüksek olduğu ve ekonomik kayıpların önüne geçilmesi için bu konuda daha fazla çalışmaya ihtiyaç olduğu ve yetiştiricilerin bilgilendirilmesi gerektiği tespit edildi.
The aim of this study was to determine the prevalence of subclinical mastitis, to isolate and identify the agent causing mastitis, and to determine their antibiotic resistance in centrum and townships of the Kırıkkale. California Mastitis Test (CMT) was performed on 629 cows. A total of 836 milk samples from 342 CMT-positive cows (54.37%) were examined microbiologically. Pathogens isolated in 213 (25.47%) dairy cows samples. The isolated agents were Staphylococcus aureus (28.17%), Staphylococcus haemolyticus (12.21%), Staphylococcus simulans (8.92%), Streptococcus uberis (8.45%), Staphylococcus hominis (4.22%), Staphylococcus capitis (3.75%), Bacillus subtilis (2.82%) and Mycoplasma spp. (2.82%). Amongst all microorganisms that caused mastitis, the higest resistance was observed to be against cloxacilline. Resistance, at the second level, was observed against penicillin in Staphlococcus aureus and coagulase negative staphylococci (CNS), and against erythromycin in streptococci. There was no resistance against vancomycin. Consequently, it was concluded that the prevalance of the subclinical mastitis with Staphlococcus aureus is high in Kırıkkale and in order to avoid economic losses, more studies are needed on subclinical mastitis and more information should be given to farmers.
