Abstract

Nontuberculosis mycobacteria are widespread in the environment and some are zoonotic. 320 tissue samples with visible lesions were obtained from dairy cows and examined by histopathology. Eleven samples showed typical granulomatous lesions and a total of 8 strains were cultured. Three genes (16S rRNA, hsp65 and rpoB) were sequenced for species identification. All mycobacterial isolates were tested for rifampicin, isoniazid, ethambutol, streptomycin, capreomycin, kanamycin, para-aminosalicylic acid susceptibility. Six strains were identified as M. fortuitum, 1 was M. avium, 1 was M. conceptionense, isolated from cattle for the first time. Seven of the 8 isolated strains showed multiple drug resistance.

Keywords: Drug resistance; Histopathology; M. fortuitum; Typical granulomatous lesions.
