- Abstract
Background: The genusSalmonella is constituted by Gram negative, facultative anaerobes; it is separated into two species, Salmonella enterica and Salmonella bongori. The species of S. enterica it has been classified into 6 subspecies, so far have identified more than 2,579 different strains (called "serotypes" or "serovars"). Foodborne infections by salmonella remain a major cause of gastroenteritis in humans. Objectives: To determine the serum variants of Salmonella spp. recovered from samples of food in the laboratory of public health in Bogota between the years 2011 to the 2014 (semester I). Methods: Retrospective study of the results obtained in the laboratory of public health of Bogotá. Taking into account the results of serotyping of strains obtained in the LSP and the district network of laboratories, the samples sent to the National Institute of drugs and food (INVIMA) monitoring as part of the external indirect performance assessment. Results: The year 2011 is received n = 2313 samples for investigation of Salmonella spp / 25g of which, 174 serotyped for this organism were confirmed, which is equivalent to a 7.5% of the samples analyzed. The year 2012 is processed n = 1821 matrices obtained, 79 results corresponding to 4.3%. An n = 2075 samples, for 2013, 55 results were positive which equals 2.7%. In addition, the first half of 2014, obtained a 20.4% of salmonella positive, i.e. 157 of 769 analyzed food samples. Distribution the two first circulating serotypes in food for 2011 was Muenster (14.4%) and Enteritidis (13.2%). In the 2012 the first was Typhimurium (27.9%) followed of Enteritidis (13.9%), for the year 2013 is identified Typhimurium (16.4%) and Enteritidis (10.9%). For the first half of 2014 Paratiphy B (21.6%) and Enteritidis (17.2%). Conclusions: It is confirmed that in the Capital District has the same tendency to recover S. Typhimurium and S. Enteritidis serotypes; as in Latin America and the Caribbean. S. Typhimurium, S. Paratiphy B, and S. Enteritidis were the most frequent serovars in food matrices, ranging in first and second place during the four years evaluated.
