Diagnosis of Mycobacterium avium complex in granulomatous lymphadenitis in slau...

The aim of this study was to compare two diagnostic methods for the detection of Mycobacterium avium complex (MAC) infection in lymph nodes with granulomatous lymphadenitis from slaughtered domestic pigs. Fifty affected lymph nodes were collected from 50 pigs and examined microscopically and by polymerase chain reaction (PCR). Microscopically, granulomatous lesions were observed in 92% of the samples, consistin...
