Methicillin resistant Staphylococcus aureus (MRSA) is one of the most important pathogenic microorganisms that display multiple drug resistance, causing severe infections in animals and humans. Contaminated or raw milk products, such as yoghurt, are one of the root causes of such MRSA infections for the consumers. Recent studies on clonal investigation revealed the same clonal isolates of animals in human infections. Thus, the epidemiology of these bacteria in food products and animals has gained importance. Therefore, the aim of this study was to epidemiologically detect MRSA in yoghurt samples from Urfa via real-time PCR. To detect MRSA via real-time PCR, the mecA gene was investigated on the DNA obtained from the yoghurt samples. Among 64 yoghurt samples, of which 55 were unpackaged and 9 were packaged, the MRSA mecA gene was only detected in 2 (3.13 %) unpackaged samples via real-time PCR. These results showed that it was possible to detect and epidemiologically investigate MRSA, an important pathogen for human and animal health, via real-time PCR from yoghurt samples with direct DNA isolation. In addition, this pathogen can be found in the products sold in Sanliurfa, which indicates that it may lead to severe diseases in case of consumption, if not conformed to hygienic conditions.
