RESUMO
INTRODUCTION: Gastrointestinal infections caused by Yersinia pseudotuberculosis are uncommon in our country and the epidemiology of the infection is uncertain. METHODS: We describe three cases of Y. pseudotuberculosis gastrointestinal infection, all detected within one month of time. A possible epidemiological relationship among these cases, as well as the microbial characteristics of the isolates, was investigated. RESULTS. No epidemiological relationships were found among the three cases. Nevertheless, all three isolates were identical according to phenotyping and molecular marker studies. CONCLUSION: This report discusses the possible source of infection in these cases, with reference to published data from sporadic cases and outbreaks of infection by this microorganism. We suggest that future studies are needed to know the real incidence of Y. pseudotuberculosis in our country.

INTRODUCCIÓN. La infección gastrointestinal producida por Yersinia pseudotuberculosis es poco frecuente en nuestro medio. Además la epidemiología de la infección es poco conocida. MÉTODOS. Se presentan 3 casos de infección gastrointestinal producidas en el período de un mes por Y. pseudotuberculosis. Se investigó la posible relación epidemiológica de los mismos, así como las características microbiológicas de los aislados. RESULTADOS. Entre los 3 casos no se ha encontrado ninguna relación epidemiológica. Los 3 aislamientos fueron idénticos tras el estudio de marcadores fenotípicos y moleculares. CONCLUSIÓN. En este informe se discute la posible fuente de infección de los casos, atendiendo a los datos previamente descritos de casos esporádicos y brotes de infección producidos por este microorganismo. Se sugiere la posibilidad de profundizar en la investigación de la incidencia real de esta infección en nuestro medio (AU)
