Özet
Bu çalışma, Konya'daki kil keçilerinde subklinik mastitis teşhisinde CMT'nin kullanılabilirliğini ortaya koymak ve subklinik mastitise neden olan bakterileri izole etmek amacıyla yapılmıştır. Çalışmada 5 adet keçi süründe bulunan toplam 508 kil keçisi incelendi. Keçilerin 985 adet memesinden süt örneği alınarak CMT testi uygulands, CMT pozitif sonuç veren süt örneklerinde ve kontrol amaciyla CMT negatil sonuç veren 50 süt örneğinde mikrobiyolojik inceleme yapıldı. CMT sonuçlarına göre keçilerin %11.7'sinde ve memelerin %7.9'unda subklinik mastitis tespit edildi. EnTeksiyon *32.2 oranında bilateralken, %67.8 oranında unilateraldi Enfeksiyonun 43.6's: sağ lopta, %56.4'0 sol lopta tespit edildi. Sağ ve sol lopta tespit edilen vakaların sayısı bakımından istatistiksel fark görülmedi (P >0.05) CMT pozitif sonuç veren örneklerin %79 5'inde bakteriyel üreme olurken, 20.5 inde herhangi bir etken izole edilmedi. CMT negatif sonuç veren örneklerin %14'ünde bakteriyol üreme olurken, %86'sında herhangi bir otkon izole edilmedi. CMT sonucunda subklinik mastitis yönünden pozitif ve negatif olarak tespit edilen örneklerin bakteriyolojik doğrulanımında statistiksel fark gözlenmedi (P >0.05) CMI pozitif sonuç veren süt üreklerinde Koagulaz negatif Staphylococcus (KNS) 69.3 pravalansla en yaygın patojen olarak belirlendi. Staphylococcus aureus ($17.7), Corynebacterium spp. (548), Streptococcus spp. (3.2). Escherichia coli (3.2) ve Maya (1.6) izole edilen diğer patojenjorai. Sonuç otarak keşilerde 0 ve +1 skorlarının negatif, +2 ve +3 skorlarının pozitif olarak kabul edildiğinde, CMT'nin subklinik olarak enfekte ve enfekte olmayan memeleri yüksek oranda tespit ettiği belirlenmiştir. Bu nedenle keçilerde subkänk mastills tephesinde kullanım kolaylığı, hızlı sonuç vermesi ve düşük maliyeti nedeniyle CMT tercih edilebilir.
The objective of this study is to evaluate of CMT for diagnosis of subclinical mastitis in Hair goat, Konya and to isolate bacteria causing subclinical mastitis. For this purpose, 508 goats were examined from five herds. Milk samples were collected from 985 mammary glands and checked by CMT. All CMT positive milk samples and a number of 50 negative milk samples (as a control) were used for microbiological analyses. According to CMT results, 11.7% of goats and 7.9% of mammary glands were classified to have subclinical mastitis. While 32.2% of the infections were bilateral, 67.8% were unilateral. Infections were detected in a ratio of 43.6% in the right glands and 56.4% in the left glands, and there was no statistical difference (P >0.05). Among the CMT positive milk samples, 79.5% had bacterial growth, whereas no bacteria were detected in 20.5%. Of the CMT negative milk samples, only 14% showed bacterial growth while 86% were free of growth. By comparision cultural results with CMT from samples obtained from subclinical cases, CMT were verified by bacterial growth (P>0.05). The mostly detected pathogen in CMT positive milk samples was Coagulaz negative Staphylococci (CNS) with a 69.3% prevalence. The other pathogens those were isolated Staphylococcus aureus (%17.7). Corynebacterium spp. (%4.8), Streptococcus spp. (%3.2), Escherichia coli (%3.2) and Yeasts (%1.6). As a result, CMT can detect subclinically infected and uninfected mammary glands with a good accuracy when 0 and +1 were considered negative and +2 and +3 were positive in hair goats. Therefore, CMT can be recommended for detection of subclinical mastitis since it is fast, easy and costeffective.
