Abstract

Background: Group A rotaviruses are a major cause of acute gastroenteritis in infant and young children worldwide. In this study, the molecular epidemiology and genetic diversity of ROTAVIRUS INFECTION among children less than 5 years old with acute diarrhea admitted in Markaz Tebbi pediatric hospital were investigated. Material and methods: Between February 2003 and January 2004, thirty hundred and seventy two stool specimens from children under 5 years old with acute diarrhea who attended at Markaz Tebbi pediatric hospital, were analyzed using ELISA, RT-PCR and RFLP. Results: Ninety-four percent were positive for the presence of rotavirus group A by ELISA. Prevalence of ROTAVIRUS INFECTION in our population study was %25.3 (%95CI: 20.9-29.7). Out of the positive samples, 49 strains were further characterized by RTPCR for identification of G types, resulting in 29 strains of G1 genotype while 20 samples could not be assigned a G type. The' sequence of the VP7 gene of many of nontypable strains was compared with those of other representative human and animal rotaviruses of different G serotypes specificities and showed that the highest identity to G9 specificity, with 98% homology at the nucleotide level. Watery diarrhea (92.6%), vomiting (73.4%) and fever (64.9%) were significantly more frequent in children suffering from rotavirus gastroenteritis. Seven out of 94 rotavirus-positive groups had severe dehydration (P<0.0001).ROTAVIRUS INFECTION mostly affected children under 2 years of age with a peak incidence of 40% in children 1 to 2 years of age and it occurs year round with a seasonal pattern: more frequently during winter (46.2%). Thirty-three RFLP patterns were identified for 36 strains. Conclusions: This study revealed that rotavirus is an important etiological agent of acute diarrhea with a high genetic diversity in G1 genotype in TEHRAN.
