Description

Although Enteroinvasive E. coli (EIEC) is a clinically important pathogen, few clinical and community studies have specifically looked for EIEC, compared to Shigellae or other diarrhea causing E. coli. Due to the lack of scientific attention in studies of diarrheal disease, the epidemiology of EIEC is poorly understood, and the degree to which EIEC is being mis-diagnosised as Shigellae is unknown. Methods: E. coli and Shigellae were identified in a case-control study in northern coastal Ecuador. Infection was assessed by PCR specific for LT and STa genes of enterotoxigenic E. coli (ETEC), the bfp gene of enteropathogenic E. coli (EPEC), and the ipaH gene of both enteroinvasive E. coli and Shigellae. Distinction between EIEC and Shigellae was achieved with biochemical tests.
Aunque la E. coli Enteroinvasiva (EIEC) es un patógeno clínicamente importante, existen pocos estudios clínicos que ha buscado específicamente a EIEC comparando con Shigellae y otras E. coli patogénicas. Es por esto que la epidemiología de EIEC es poco entendida y el grado de confusión con Shigellae es desconocido. Métodos: En este estudio de caso-control en la costa norte del Ecuador fueron analizadas E. coli patogenicas y Shigellae. Mediante PCR especifico para los genes LT y STa se identificaron a las E. coli enterotoxigenicas (ETEC), el gen bfp para las E. coli enteropatogenicas (EPEC) y el gen ipaH para identifiar a Shigellae y E. coli enteroinvasiva (EIEC). La distincion entre EIEC y Shigella se realizo mediante pruebas bioquimicas.
