| etiologic agents of acute gastroenteritis among japanese infants and children: virus diversity and genetic analysis of sapovirus. | a total of 371 fecal specimens from infants and children with acute gastroenteritis in maizuru, tokyo and osaka, japan from july 2002 to june 2003 were tested for the presence of diarrheal viruses by reverse transcription-polymerase chain reaction (rt-pcr), reverse passive hemagglutination (prha), rna-polyacrylamide gel electrophoresis (page), latex agglutination and sequence analysis methods. among diarrheal viruses detected, group a rotavirus was the most prevalent (42.2%) followed by noroviru ... | 2005 | 15789264 |
| three-year survey of the epidemiology of rotavirus, enteric adenovirus, and some small spherical viruses including "osaka-agent" associated with infantile diarrhea. | studies were made by electron microscopy (em) on the viruses associated with diarrhea of outpatients at a pediatric clinic in osaka prefecture during the three year period from 1980 through 1982. the viruses detected by em by negative staining with phosphotungstic acid (pta) were classified morphologically into 6 groups: rotavirus, adenovirus and four kinds of small spherical viruses, calicivirus, astrovirus, picornavirus/parvovirus (p/p)-like agent and osaka-agent. osaka-agent seems to be a new ... | 1985 | 3000350 |
