RESUMO

OBJECTIVE: To identify the different Salmonella strain serotypes isolated at public and private laboratories in Mexico and at the Institute for Epidemiologic Diagnosis and Referral (InDRE). MATERIAL AND METHODS: A total of 24,394 Salmonella strains collected from 1972 to 1999 in public and private health laboratories of Mexico were analyzed with the Kauffmann-White method, using antisera produced by InDRE, according to Centers for Disease Control and Prevention (CDC, Atlanta, GA) standards; 15,843 (64.9%) samples were from human sources and 8,551 (35.1%) from non-human sources. RESULTS: One hundred ninety nine different serotypes were identified. The most frequent serotype in human beings was S. Typhimurium (20.4%), followed by S. Enteritidis (18.3%). In the past few years, the frequency of S. Enteritidis has been increasing, surpassing that of S. Typhimurium since 1991. Presently S. Enteritidis is the most frequently isolated serotype. In non-human sources, S. Derby (13.8%) and S. Anatum (8.5%) are the most frequent strains. CONCLUSIONS: Salmonella serotypes most frequently isolated in Mexico are: S. Typhimurium, S. Enteritidis, S. Derby, S. Agona y S. Anatum. From the epidemiologic standpoint, it is necessary to identify circulating and emerging Salmonella serotypes in order to target pertinent preventative interventions.
