First genetic characterization of rotavirus C in Russia.

Rotaviruses C (RVC) cause sporadic cases and outbreaks of diarrhea in humans and animals worldwide. The aim of this study was to monitor RVC during a surveillance study of sporadic cases of viral gastroenteritis in the Novosibirsk and Omsk regions of Russia from 2006 to 2011. A total of 2144 stool samples from children and adults hospitalized with acute gastroenteritis were tested for RVC by RT-PCR.

Human bocavirus in hospitalized children with acute gastroenteritis in Russia from 2010 to 2012.

Human bocavirus (HBoV) can cause respiratory diseases and is detectable in the stool samples of patients with gastroenteritis. To assess the prevalence of HBoV in children hospitalized with acute gastroenteritis in Novosibirsk, Russia, as well as its genetic diversity and the potential role in the etiology of gastroenteritis in this region, a total of 5502 stool samples from children hospitalized with gastroenteritis from 2010 to 2012, n=5250, and healthy children, n=252, were assayed for the presence of HBoV DNA by semi-nested PCR. The HBoV DNA was found in 1.

Molecular epidemiology of noroviruses associated with sporadic gastroenteritis in children in Novosibirsk, Russia, 2003-2012.

Noroviruses (NoVs) are an important cause of acute gastroenteritis worldwide. To monitor the molecular epidemiology of NoVs genogroup II (GII) in Novosibirsk, Russia, a total of 10,198 stool samples from young children hospitalized with acute gastroenteritis and two asymptomatic comparison groups were collected from 2003 to 2012. All samples were screened for the presence of NoV GII, rotavirus, and astrovirus by RT-PCR.

[Rotaviruses in younger children in Novosibirsk in 2005-2007: detection and genotyping].

Examination of 1898 patients with acute enteric infection from March 2005 to February 2007 showed that group A rotaviruses were the most frequent cause (35%) of acute gastroenteritis among children under 3 years of age. Majority of cases of rotavirus infection was detected in infants under 1 year of age (71.8%).
