Eurasian Journal of Veterinary Sciences, 6(1), 3-6.1309-69582146-1953https://hdl.handle.net/20.500.12395/48014This investigation was performed on 800 milch sheep belonged two state farm in Konya region. Sheep were examined by clinical procedures and tested with California Mastitis test (CMT). Milk samples taken from sheep with mastitis (CMT scores, +++++) were cultured in aerobic, microaerophlic and anaerobic conditions for bacteriological and mycological examination bacteria isolated and identified were tested against Ampicillin, Streptomycin, Tetracyclin, Penicillin, Kanamycin, Erytromycin, Gentamycin and Chloramphenicol discs (Difco). In this area, in the mammary glands of 13.5 % of the tested sheep, mastitis was detected. Although the rates of clini cal mastitis was 0.75 percent, subclinical mastitis in sheep was 12.75 percent. Microbiologic isolation were succeded from (75.0 %) 81 samples of 108 mastitic milk. But, there was mix infection in 8 samples. The percent values of isolated microorganisms were found as below 57.3 % Staph. aureus, 9.0 % for E. coli, 7.9 % for Bacillus ssp. 5.0 % for B. cereus, 5.0 % for C. pyogenes (Actinomyces pyogenes), 3.4 % for Str. agalactiae, 3.4 % for C. pyogenes (Actinomyces pyogenes), 3.4 % for Str. agalacti- ac, 3.4 % for K. pneumoniae, 3.4 % for Candida albicans, 2.2 % for B. subtilis, 1.1 % for Str. dysgalactiae and 1.1 for Ente- robacter ssp. In antibiotic susceptibility tests, Staph. aureus isolates were found to be sensitive to Tetracyclin, Chloramphenicol and Erytromycin, at the rates of 76.0 %, 58.0 % and 38.0 %, respectively, E. coli strains were sensitive to Streptomycin (100%) and Tetracyclin (100 %), C. pyogenes strains were sensitive at the rates of 100 %, 80.0 % and 80.0 %, for Penicil- lin, Streptomycin and Chloramphenicol, respectively.Bu çalışma, Konya yöresindeki iki devlet kurumuna ait 800 sağmal koyun üzerinde yapıldı. Hayvanlar, California Mastitis Test (CMT) ile ve klinik olarak muayene edilerek, klinik ve subklinik mastitisli memeler tespit edildi. CMT bulgulan ++ ve +++ olan memelerden alınan süt örnekleri aerobik, mikroaerofilik ve anaerobik olarak bakteriyolojik ve mikolojik yönden incelendi. Ayrıca izole ve identifiye edilen bakterilerin antibiyotiklere duyarlılıkları saptandı. Antibiyotiklere duyarlılık testlerinde; Ampisilin, Streptomisin, Penisilin, Kanarisin, Eritromisin, Gentamisin, Tetrasiklin ve Kloramfenikol diskleri (Difco) kullanıldı. Bölgede CMT ile taranan 800 koyunun 108% (% 13.5) mastitisli olarak saptandı. Bu 108 koyunun 102'si (% 12.75) subklinik, 6'sı (% 0.75) klinik mastitisli bulundu. Mastitisli süt örneklerinin 81'inden (% 75.0) patojen mikroorganizmalar üretildi. Süt örneklerinin 8'inde miks infeksiyon tespit edildi. İzole edilen mikroorganizmaların yüzde oranlar arasıyla; Staph. aureus 57.3, E. coli 9.0, Bacillus sap 7,9, B. cereus 5.0, C. pyogenes (Actinomycespyogenes) 5.0, Str. agalactiae 3.4, K. pneumoniae 3.4, Candida albicans 3.4, B. subtilis 2.2. Str. dysgalactiae 1.1 ve Entero bacter ssp. 1.1 olarak saptandı. Antibiyogram testlerinde Staph. aureus; Tetrasiklin'e % 76.0, Kloramfenikol'e % 58.0 ve Eritromisin'e % 38.0, E coli; Streptomisin ve Tetrasiklin'e % 100, C. pyogenes; Penisilin'e % 100, Streptomisin ve Kloramfenikol'e % 80.0 oranında duyarlı bulundu.trinfo:eu-repo/semantics/openAccessArticle6136
