Resumen
TALAVERA ROJAS, Martín et al. Genetic diversity of Salmonella typhimurium (Group B) isolates from chicken livers intended for human consumption. Rev. mex. de cienc. pecuarias [online]. 2011, vol.2, n.4, pp.371-380. ISSN 2448-6698.
Frequency of Salmonella spp in chicken livers for sale, in four markets of the metropolitan area of Toluca, Mexico, was determined. The bacteriological isolation was carried out according to the Norma Oficial Mexicana-114-SSA1-1994 for Salmonella assessment in food. The ERIC-PCR test was carried out to determine genetic diversity of isolated Salmonella strains. Out of 520 samples included in the study, seven (1.34 %) were positive to Salmonella serotype B (typhimurium). Four profiles were observed in ERIC-PCR, finding similarity among strains from different markets, which may indicate that management of carcasses and viscera is of great importance, also that presence of chicken liver for human consumption must be considered as an important source of infection, since any serotype of this bacterium represents a potential infection for humans.
