Isolation of Some Aerobic Bacteria and Mycoplasma spp. from Goat Milk with Clinical and Subclinical Mastitis

Year 2016, Volume: 27 Issue: 2, 74 - 78, 20.08.2016

Abstract

In this study, it was aimed to isolate some aerobic bacteria and Mycoplasma species from the milk samples collected from the goats with clinical and subclinical mastitis. A total of 188 milk samples were collected from the 5 different goat farms. Of the 188 samples, 13 (6.9%) were clinical mastitis and 175 (93.1%) were subclinical mastitis that was evaluated by California mastitis test (CMT).  Of the 188 samples, 135 (71.8%) were positive and 53 (28.2%) were negative by bacteriological culture. When CMT and culture results were compared, of the 184 CMT positive milk samples, 135 (73.3%) were positive and 49 (26.7%) were negative by culture. As pure culture, 34 (25.1%) milk samples were positive for Staphylococcus aureus, 21 (15.5%) for coagulase negative staphylococci(CNS), 18 (13.3%) for Micrococcus spp., 9 (%6.6%) for Streptococcusspp., 5 (3.7%) for Staphylococcus epidermidis, 4 (2.9%) for Escherichia coli, 1 (0.7%) for Enterococcus columbae, 1 (0.7%) for Pasteurella multocida, 1 (0.7%) for Enterococcus spp., 1 (0.7%) for Listeria spp., 1 (0.7%) for Klebsiella spp., 1 (0.7%) for Enterobacter spp., 1 (0.7%) for fungus. Mycoplasma spp. were not isolated from any of the tested samples. The results of this study can be summarized as follows: i) when CMT and culture results (49 samples tested positive by CMT, but negative by culture) were compared by two proportion method, statistical relationship between CMT and culture was statistically significant (< 0.001). So, the CMT was not enough to give reliable results for the pre-detection of subclinical mastitis in goats; ii) the ideal planting method applied to goat's milk was seen as after 10 min centrifugation at 4000 rpm was streaked from the pellet by cotton swab; iii) the isolation rate from the milk samples with clinical mastitis is higher than the milk samples with subclinical mastitis; iv) the majority of the streptococci belong to serogroup D; v) the most prevalent isolated bacteria from both the milk samples with clinical mastitis and the milk samples with subclinical mastitis were S. aureus and CNS.

Klinik ve Subklinik Mastitisli Keçi Sütlerinden Bazı Aerobik Bakteri ve Mycoplasma spp. İzolasyonu

Year 2016, Volume: 27 Issue: 2, 74 - 78, 20.08.2016

Abstract

Bu çalışmada, Van ve Hakkâri yöresinde yetiştirilen klinik ve subklinik mastitisli keçi sütlerinden bazı aerobik bakterilerle, mikoplazmaların izolasyonu amaçlandı. Çalışma kapsamında, 5 farklı işletmede barınan 13 (%6.9) adeti klinik, California mastitis testi (CMT) ile yapılan değerlendirmeye göre ise 175 (%93.1) adeti subklinik mastitisli olan toplam 188 adet keçiden alınan aynı sayıdaki süt örneği incelendi. İzolasyon sonuçları toplam olarak değerlendirildiğinde, 188 adet süt örneğinin 135’inden (%71.8) kültür pozitif sonuç alınırken, 53 (%28.2) örnekten ise her hangi bir bakteri üremesi olmadı. CMT ve kültür sonuçları karşılaştırıldığında, CMT pozitif 184 süt örneğinden 135’i (%73.3) kültür ile de pozitif sonuç verirken, 49’u (%26.7) ise negatif sonuç verdi.  Saf kültür olarak gerek klinik mastitisli gerekse subklinik mastitisli keçi sütlerinden en yüksek oranda 34 (%25.1) Staphylococcus aureus üredi. Bunu takiben saf kültür olarak örneklerin 21’inden (%15.5) koagulaz negatif stafilokoklar (KNS), 18’inden (%13.3) Micrococcus spp., 9’undan (%6.6) Streptococcus spp., 5’inden (%3.7) Staphylococcus epidermidis, 4’ünden (%2.9) Escherichia coli, 1’inden (%0.7) Enterococcus columbae, 1’inden (%0.7) Pasteurella multocida, 1’inden (%0.7) Enterococcus spp., 1’inden (%0.7) Listeriaspp., 1’inden (%0.7) Klebsiella spp., 1’inden (%0.7) Enterobacterspp. ve 1’inden (%0.7) ise maya izole edildi. İncelenen örneklerin hiç birinden Mycoplasma spp. izole edilmedi. Sonuç olarak; i) CMT ve bakteriyolojik kültür sonuçları Z oran testine göre karşılaştırıldığında; CMT pozitif, kültür negatif (49 örnek) sonuçlar arasındaki farkın istatistiksel olarak önemli olduğu (< 0.001) belirlendi ve bu nedenle, CMT’nin keçilerdeki subklinik mastitislerin ön teşhisinde yeteri düzeyde güvenilir sonuç vermediği, ii) keçi sütlerine uygulanan ideal ekim yönteminin, 4000 rpm’de 10 dk santrifüj işleminden sonra “tortudan svabla yapılan yayma yöntemiyle ekim” olduğu, iii) klinik mastitisli süt örneklerinden, subklinik mastitisli örneklere göre daha yüksek oranda bakteri izole edildiği, iv) izole edilen streptokokların büyük çoğunluğunun D serogrubuna ait oldukları, v) mastitisli keçi sütlerinden en yüksek oranlarda S. aureus ile KNS’ın izole edildiği belirlendi.
