Description
Summary:Introduction: Salmonella enterica serotype Typhimuri-um variant 5- is a pathogen closely related to animals, especially pigeons, which has been also associ- ated in rare cases with sporadic infections in humans. However, epidemiological surveillance systems have enabled the detection of this variant in human out- breaks. Objective: To characterize by means of phenotypic and genotypic techniques the isolates of Salmonella Typhimurium variant 5- associated with an outbreak of food-borne disease in Paz de Rio, Boyacá, Colombia (2010), in order to establish their molecular relationships. Materials and methods: Twelve isolates of Salmonella -spp., were analyzed by biochemical, serotyping and antimicrobial susceptibility tests. Pulsed-field gel electrophoresis (PFGE) with Xball Blnl enzymes was used to establish their molecular relationships Results: All isolates were confirmed as Salmonella spp. They were resistant to tetracycline and streptomycin and sensitive to the rest of antibiotics tested. Eleven isolates were identified as Salmonella Typhimurium variant 5- and grouped in COIN10.JPX.X01.0168 pattern using the enzyme Xball two isolates in this group were confirmed using the enzyme Blnl with the COIN10.JPX.A26.0002 pattern. One isolate was identified as Salmonella Typhimurium with COIN10.JPX.X01.0221 pattern with the enzyme Xbal Conclusion: This is the first outbreak in Colombia of foodborne illness epidemiologically associated with isolates of Typhimurium variant 5 -, which Epidemiologic Sur were phenotypically and genetically related.
