Spoligotyping of M. tuberculosis strains from cattle in Turkey [Türkiye’de sığırlardan İzole edilen M. tuberculosis suşlarının spoligotiplendirmesi]

Although it is generally accepted that M. Bovis leads to tuberculosis in cattle, there are statements given from the different regions of the world, referring to the fact that M. tuberculosis, which is known as the human tuberculosis agent, causes tuberculosis in cattle as well. The material of the study consisted of 13 M. tuberculosis isolates which were isolated and identified from the organ pieces of 95 cattle with the culture methods; these organ pieces had been taken from the cattle with granulomatous lesion detection after the slaughtering in slaughterhouses located in Çukurova region and brought to the laboratory under sterile conditions. It was determined in the genotyping conducted by using the Spoligotyping method that 13 of the 55 isolates were M. tuberculosis and they belonged to the T1 family (SIT53) by becoming dense in one cluster (100%). Consequently, it was shown with this study that M. tuberculosis, which leads to tuberculosis in humans, could be transmitted from humans to animals and from animals to humans again, and researching the human and epidemiological tuberculosis cases by using molecular epidemiology-based methods such as spoligotyping might provide useful information about explaining the ways of transmission of tuberculosis. © 2015, Veteriner Fakultesi Dergisi.
