Salmonella is one of the most important causal agents of foodborne illness around the world, causing a several problems of health. In Sinaloa there is a high amount of cases of salmonelosis, an average of 5,000 cases per year. This means there are 300 cases of salmonella per 100,000 habitants. As a result Sinaloa loses a lot of money in agriculture and aquaculture. We are carrying out an epidemiology study in order to know how this organism is distributed among all environments. We work with 55 strains recollected from many sources during the years 2001 - 2007. The studied sources were clinical prepared foods, seafood, water, meats, chicken and milk products. These were analyzed in the laboratory of public health and the isolated (were) stored at -70°C. The serotyping was made with antisera agglutination test for classification in groups and seroytpes. The profile genetic characterization was analyzed by Pulsed Field Gel Electrophoresis using Xba I for the digestion. The results of PFGE were processed by bionumerics pulse net software to compare between profiles of each isolate.
