Occurrence of enteropathogenic bacteria in children under 5 years with diarrhoea in south Tehran

This study was carried out on 1600 rectal swabs from children under 5 years of age admitted at the health centre in Islamshahr, Tehran province, Islamic Republic of Iran, during 1998-99. The specimens were examined for various bacterial pathogens. Isolation rates were: enteropathogenic Escherichia coli 6.8%, Shigella spp. 3.4%, Salmonella spp. 2.9%, Campylobacter spp. 0.9%, Yersinia spp. 0.7%. The isolation rate was highest in the summer, except for Yersinia spp., which was predominantly isolated in spring. The results of this study demonstrate the significance of Yersinia spp. And Campylobacter spp. in patients with diarrhoea

Frequency of Yersinia species infection in paediatric acute diarrhoea in Tehran

This study determined the frequency of Yersinia enterocolitica infection in 300 children with acute diarrhoea aged 0-12 years who were attending a paediatric hospital in Tehran. Over the 5-month study [May-September 2002], Yersinia species and other organisms were cultured and serotyped from stool samples or swabs. Yersinia spp. were found in 8 cases [2.7%]. Enteropathogenic Escherichia coli was isolated in 5.7% of cases, Shigella spp. in 3.0% and Salmonella spp. in 2.0%. None of the Y. enterocolitica belonged to the common serotypes of O:3 and O:9. Atypical Yersinia spp. [Y. intermedia and Y. frederiksenii] were isolated. All Y. enterocolitica isolates had a similar pattern of antimicrobial resistance. Yersinia spp. infections are not common in the summer months in Tehran
