Summary:
The disease caused by Shigella spp. are significant diarrheal disease and mortality in humans, as there are approximately 165 million episodes of shigellosis and 1.1 million deaths annually. Colicin-mediated killing which has been found among several bacteria, including Shigella spp. Thirty-seven Shigella spp. strains were isolated from diarrheal endemic from 1995-2016. These Shigella spp. strains were characterized by PCR to screen for E type colicin production. S. flexneri is the most prevalent species (78.4%), followed by S. sonnei (24.5%). Eleven Shigella strains geographically related showed the colicin genotypes. Colicino type E5 was predominant in Nha Trang where E8 and E9 commonly found in Hue. In the PCR-based detection of the colicin types for thirty-seven Shigella strains, 7 (18.9%) were identified as E5, 6 as E8 (16.2%), and 2 as E9 (5.40%). No strain was found to produce E1, E2, E3, E4, E6 and E7. It is to our knowledge; the first report on prevalence of E-type colicin produced by Shigella sp. isolated from patients with diarrhea in Vietnam
