Yıl 2014, Cilt: 25 Sayı: 2, 33 - 38, 15.12.2014

Öz

Bu çalışmada, klinik olarak sağlıklı sığırların nazal florasını oluşturan aerobik bakterilerin belirlenebilmesi için,
alınan nazal sıvap örneklerinden izole edilen etkenlerin, 16S rRNA dizi analizi ile moleküler identifikasyonlarının yapılması
amaçlandı. Çalışmada 15 çiftlikteki 56 sığırdan alınan nazal sıvap örnekleri kullanıldı. Nazal sıvaplardan konvansiyonel
yöntemler kullanılarak bakteri izolasyonu gerçekleştirilip, etkenlerin makroskobik ve mikroskobik morfolojileri
incelendikten sonra, identifikasyonları üniversal primerler kullanarak 16S rRNA geni polimeraz zincir reaksiyonu
ile çoğaltıldı. İzolasyonları yapılan 192 mikroorganizmanın sekans analizi ile 143 (%74,5)’ünün Gram pozitif ve 49
(%25,5)’unun Gram negatif mikroorganizma olduğu tespit edildi. Koagulaz negatif stafilokoklar (%36,5), Bacillus sp.
(%15,6), S. aureus (%11,0), M. haemolytica (%6,3), Enterobacteriaceae sp. (%6,8), P. multocida (%5,2), M. luteus
(%4,2), Streptococcus sp. (%2,6), Acinetobacter sp. (%2,6), Pseudomonas sp. (%2,1) ve Corynebacterium sp. (%1,0)
en çok identifiye edilen türler olarak belirlendi. Bu çalışmada konvansiyonel mikrobiyolojik yöntemler ve moleküler
identifikasyon yöntemlerinin büyük oranda birbirleri ile uyumlu oldukları görüldü. Bundan sonra yapılacak olan çalışmalarda,
floradan izole edilen mikroorganizmaların virulens ve antibiyotik direnç genlerinin incelemesi yapılabilir.

Molecular identification of bacteria of flora nasal cavity of healthy calves

Öz

This study aimed to carry out the molecular identification of aerobic bacterial nasal flora of clinically healthy
calves, collected by nasal swabs, by using 16S rRNA sequence analysis. Nasal swab samples from 56 calves on 15
farms were used in the study, isolation of bacteria was carried out by using conventional methods, after examining
the macroscopic and microscopic morphology of the factors, their identifications were carried out by using universal
primers duplicating polymerase chain reaction of 16S rRNA gene. With the sequence analysis of the isolated 192
micro-organisms, it was determined that 143 (74.5%) were Gram-positive and 49 (25.5%) were Gram-negative microorganisms.
Coagulase-negative staphylococci (36.5%), Bacillus sp. (15.6%), S. aureus (11.0%), M. haemolytica (6.3%),
Enterobacteriaceae sp. (6.8%), P. multocida (5.2%), M. luteus (4.2%), Streptococcus sp. (2.6%), Acinetobacter sp.
(2.6%), Pseudomonas sp. (2.1%) and Corynebacterium sp. (1.0%) were the most commonly identified species. In our
study, results of conventional methods microbial and molecular identification techniques were found to be similar. It
was suggested that virulence and antibiotic resistance genes of the most common agents isolated from flora should be
determined at the future studies.
