BACKGROUND/PURPOSE Viral infections are the most common causes of acute infectious diarrhea in the pediatric population. To explore any possible microbial etiologies of acute gastroenteritis in children, we detected stool viral antigen including rotavirus, adenovirus, norovirus and astrovirus. We also studied the possible precipitating factors. METHODS During a period of 1 year (from October ...

Currently, there are a few reports on viral coinfection that causes an acute watery diarrhea in Korean children. So, to evaluate the features of coinfectious viral agents in children with acute watery diarrhea, we enrolled 155 children with acute watery diarrhea from July 2005 to June 2006. Fecal samples were collected and evaluated for various viral infections such as rotavirus, norovirus, ade...

By reverse transcription-PCR or PCR, among 257 children with nonbacterial acute gastroenteritis (AGE), rotavirus, norovirus, astrovirus, enteric adenovirus, and multiple viruses were identified in 78 (30.4%), 21 (8.2%), 7 (2.7%), 51 (19.8%), and 53 (20.6%) patients, respectively. Higher disease severity was found for AGE caused by multiple viruses and by rotavirus alone. The majority of rotavir...

The lumen of the gastrointestinal tract harbors a diverse community microbes, fungi, archaea, and viruses. In addition to occupying same enteric niche, recent evidence suggests that microbes viruses can act synergistically and, in some cases, promote disease. this review, we focus on disease-promoting interactions gut microbiota rotavirus, norovirus, poliovirus, reovirus, astrovirus. Microbes m...

Recent studies have revealed the presence ofastroviruses and rotavirus in numerous poorly performing and healthy chicken and turkey flocks in the United States. The phylogenetic analysis of the sequence data produced during these studies has identified four groups of avian astroviruses circulating in the United States: turkey astrovirus types 1 and 2 (TAstV-1 and TAstV-2), avian nephritis virus...
