<p style="text-align: justify"><strong>Background:</strong> Acute gastroenteritis is a major cause of
morbidity and mortality among children in developing countries.
Rotaviruses are recognized as the most common etiologic factors of
gastroenteritis. In this study, we determined the epidemiologic
features, clinical symptoms and molecular structure of rotavirus VP4(P)
genotypes in children with acute diarrhea in Bahrami Hospital in Tehran
Iran, during 2009 for justifying the routine use of rotavirus vaccines
in children.<br> <strong></strong></p>
<p style="text-align: justify"><strong>Methods:</strong> One hundred fifty fecal samples from
150 children with acute diarrhea in Bahrami Pediatric Hospital in
Tehran, Iran were collected from January to December 2009. The patients’
mean age was 20.90<span style="text-decoration: underline">+</span>18.19 years (ranging from 1 month to 14 years).
Fecal samples were transported on ice to the laboratory of virology
department of Pasture Institute of Iran. The demographic and clinical
data for each case were entered in an author-devised questionnaire.
Group A rotavirus was detected by dsRNA-PAGE. Subsequently, rotavirus
genotyping (VP4) was performed by semi-nested multiple RT-PCR and the
phylogenetic tree of the Rotavirus nucleotides was constructed. The data
were analyzed by statistical tests including Wilcoxon signed and
Mann-Whitney U.<br> <strong></strong></p>
<p style="text-align: justify"><strong>Results:</strong> Rotavirus was isolated in 19.3% of the
samples, more than 90% of which had long RNA patterns. The predominant
genotype (VP4) was P[8] (86%) and other genotypes respectively were P[6]
(6.9%) and P[4] (6.9%). <br> <strong></strong></p>
<p style="text-align: justify"><strong>Conclusion:</strong> A high prevalence of the P[8]
genotype was found to be the cause of acute diarrhea. The analysis of
P[8] genotype sequence showed a high level of similarity of the virus in
this study with those of other Asian countries.</p>
