Mycobacterium bovis is a major cause of zoonotic diseases. The present study was aimed to evaluate the potential role of cats and mice in the transmission of Mycobacterium in cow dairy herds.A total of 7 cats and 5 mice were screened from an animal husbandry. Gastric acids of captured cats were cultured on LJ (Löwenstein–Jensen). The liver, spleen, and lung of mice were cultured on LJ medium followed by sterilization. The acid-fast staining and also PCR were used for detection of Mycobacterium spp. Five from 7 cats were positive by acid-fast staining and PCR 16SrRNA were confirmed the environmental Mycobacterium additional one from 7 cats was positive by acid-fast staining, PCR and 16SrRNA sequencing methods was confirmed the Mycobacterium tuberculosis Complex (MTB). Three out of 5 mice were positive by acid-fast staining. PCR and 16S rRNA sequencing methods were confirmed the Mycobacterium tuberculosis Complex (MTB). Currently, we are conducting PCR-RFLP and RP Typing to identify this bacterium more precisely.We indicated that the mice and cats are potential source for Mycobacterium spp. Thus, they can infect dairy cattle farms.
