Abstract
This investigation was undertaken on Simental cows that imported from Germany to the central country of Kars province. Examined animals were in first lactation period and their age was two. A total of 304 milk samples were examined for mastitis by CMT. A total of 71 mastitis milk samples collected from 51 mastitis cows (16.77%) were investigated for pathogenic bacteria, fungi and mycoplasma. Isolated and identified bacteria were also tested for drug sensitivity characters against to linkomycin, ampicillin+sulbactam, erythromycin, cephaperazon, enroflaxacin, danoflaxacin, sulphamethaxazole+trimethoprim and penicillin. Identification and antibiotic sensitivity tests of bacteria isolated were performed by routine microbiological methods. Of the cows examined 48 (15.78%) was sub-clinic and 3 (0.98%) was clinic mastitis. Totally 57 strains were isolated and identified from 52 CMT positive milk samples. From CMT positive milk samples 17 Staph. aureus (29.82%), 10 Staph. epidermidis (17.54%), 8 Str. agalactiae (14.03%), 5 Str. dysgalactiae (8.77%), 5 Candida spp. (8.77%), 4 Str. uberis (7.02%), 2 Micrococcus spp. (3.50%), 2 E. coli (3.50%), 2 Enterobacter spp. (3.50%), 1 Diplococcus spp. (1.75%), 1 'Bacillus spp. (1.75%) were isolated. No mycoplasmal agent was isolated. The most effective antibiotics were ampicillin+sulbactam, enrofloxacin, danofloxacin and cephaperazon.
Özet
Bu araştırma Kars ili merkez köylerine, ithal olarak getirilen Simental ırkı, 2 yaşında ve ilk laktasyon döneminde olan inekler üzerinde yürütüldü. Bu sığırlardan 304'ü California Mastitis Testi (CMT) ile muayene edildi. CMT pozitif 51 (%16.77) mastitisli inekten 71 süt örneği alınarak mikrobiyolojik muayene yapıldı, izole ve identifiye edilen bakterilerin Linkomisin, Ampisilin+Sulbaktam, Eritromisin, Enrofloksasin, Danofloksasin, Sulfametaksasol+ Trimetroprim ve Penisiline karşı olan duyarlılıkları Diagnostic Sensitivity Test (DST) Ağarda Kirby-Bauer disk diffuzyon yöntemiyle belirlendi. Araştırmada ineklerin 48'nin (%15.78) subklinik, 3'nün (%0.98) klinik mastitis olduğu saptandı. Mikrobiyolojik yoklamaya tabi tutulan 71 süt örneğinin 52'sinde (%73.24) toplam 57 aerobik etken izole ve identifiye edildi. Bu etkenlerin 17'si (%29.82) Staph. aureus, 10'u (%17.54) Staph. epidermidis, 8'i (%14.03) Str. agalactiae, 5'i (%8.77) Str. dysgalactiae, 5'i (%8.77) Candida spp., 4'ü (%7.02) Str. uberis, 2'si (%3.50) Micro-coccus spp., 2'si (%3.50) E. coli, 2'si (%3.50) Enterobacter spp., 1'i (%1.75) Diplococcus spp., 1'i (%1.75) Bacillus spp. olduğu saptandı. Mastitislt süt örneklerinin PPLO ağara yapılan ekimlerinden herhangi bir mikoplazma türü izole edilemedi. İzole ve identifiye edilen bakterilere karşı yapılan antibiyogram testinde en etkili antibiyotiklerin; Ampisilin+Sulbaktam, Enrofloksasin, Danofloksasin ve Sefaparazon olduğu belirlendi.
