ABSTRACT
No regulations currently require the excision of lymph nodes from pig carcasses or the thermal processing of pork before consumption. Therefore, the presence of anatomopathological lesions with signs of coagulation necrosis in lymph nodes from pigs during post-mortem inspection is concerning, as is the increasing incidence of mycobacteriosis in humans. Therefore, the aim of the present study is to verify whether mycobacteria can be isolated from tuberculous-like lesions in mandibular lymph nodes in slaughtered pigs, and whether further molecular analysis based on MIRU-VNRT, used to identify mycobacteria from the Mycobacterium avium complex, can indicate zoonotic potential. Forty of the fifty isolates from the lymph nodes with signs of coagulation necrosis were classified as Mycobacterium avium complex. MIRU-VNTR analysis allowed for the isolation of six strains, one of which was classified as M. avium subsp. paratuberculosis (MAP). Our findings confirm the presence of atypical mycobacteria in the lymph nodes of slaughtered pigs. While the isolated strains (other than MAP) do not pose a significant or direct health risk to consumers, further research and monitoring are necessary. Atypical mycobacteria can cause a wide range of diseases in children and compromised adults, and often show resistance to many classes of antibiotics, including those used to treat tuberculosis.
