Abstract

|
Nontuberculous mycobacteria (NTM) often confounds the interpretation of skin test in tuberculosis diagnosis, resulting in false-positive reaction. And, NTM are emerging pathogens that cause opportunistic infections in both humans and animals. The prevalence of NTM on human disease has been well investigated, whereas that of NTM on animal disease is not well established in Korea. The aim of this study was to determine the prevalence of NTM on cattle, which did not have symptoms of tuberculosis disease. A total of 426 isolates were collected in Korean native cattle and dairy cattle from 2007 to 2010. The most frequently isolated organisms were Mycobacterium peregrimum (n=5, 28%), Mycobacterium fortuitum (n=3, 17%), Mycobacterium intracellulare (n=2, 11%), Mycobacterium phlei (n=1, 5.6%), Mycobacterium terrae (n=1, 5.6%), Mycobacterium llatzerense (n=1, 5.6%), and Norcadia spp. (n=1, 5.6%). It seems to be necessary to further study the prevalence of NTM on environment (water, soil, feces) as well as animals.
