Abstract
ESPINAL MARIN, Paula; PRIETO SUAREZ, Edgar; OTERO JIMENEZ, Vanessa and MATTAR VELILLA, Salim. Presence of the invasive gene invA in Salmonella spp: strains isolated from food in several cities of the Colombian Caribbean area. Rev Cubana Salud Pública [online]. 2006, vol.32, n.2. ISSN 0864-3466.
Objective: to establish the presence of invasive gene invA in Salmonella spp. strains obtained from food in several cities of the Colombian Caribbean area. Methods: from January 2002 to March 2003, a microbiological study of quality control of food was carried out in four cities of the Colombian Caribbean area. One thousand and three hundred food samples were analyzed in fast food outlets located in city squares or markets. Results: seventy four isolates of Salmonella were recovered: 30 (40.5) in meat; 13 (17.6 %) in sausage; 12 (16.2 %) in chicken; 9 (12.2 %) in cheese; 6 (8.1 %) in pork and 4 (5.5 %) in other types of food. The most frequently isolated serotypes were S.anatum in 14 (18.9 %), S.uganda in 13 (17.6 %), S. newport in 9 (12.2 %) y S. typhimurium in 7 (9.5 %). The invA primer amplified 378 pb fragment, invA gene was detected in 72 (97.3 %) Salmonella isolates. Conclusions: it was possible to detect the invA gene in circulating serotypes of Salmonella isolates obtained from food in the Colombian Caribbean area, the epidemiological implications allow the health authorities to take measure for the prevention, control and diagnosis of Salmonella infection in the Colombian Caribbean area
