Norwalk-like viruses (NLVs), rotavirus and adenovirus are reportedly responsible from 4 to 42% of non-bacterial acute sporadic gastroenteritis. The incidence of NLVs, adenovirus and rotavirus infections in Indonesia is unclear. A total of 402 symptomatic cases from Indonesian patients with acute gastroenteritis and 102 asymptomatic controls that tested negative for bacteria and parasites were screened for the presence of NLVs, rotavirus and adenovirus using the reverse transcriptase-polymerase chain reaction (RT-PCR), Rotaclone kits and Adenoclone kits.

Experimental infection of Macaca nemestrina with a Toronto Norwalk-like virus of epidemic viral gastroenteritis.

Norwalk virus (NV) and Norwalk-like viruses (NLVs) are common etiologic agents of viral gastroenteritis. Viral gastroenteritis is a common disease that is highly transmissible, spreading rapidly through families, institutions, and communities. Because methods for in vitro cultivation of Norwalk etiologic agents are not available, information regarding this syndrome has come largely from studies in human volunteers.

Toxins and colonization factor antigens of enterotoxigenic Escherichia coli among residents of Jakarta, Indonesia.

Infection caused by enterotoxigenic Escherichia coli (ETEC) poses a serious health problem among children and adults in developing countries. Colonization of the small intestinal mucosa by ETEC strains is mediated by antigenically specific fimbriae, also known as colonization factor antigens (CFA). The significance of this study arises from reports that active and passive immunization with ETEC strains harboring CFAs has previously been shown to induce protective immunity against diarrhea in animal models.

Shigella spp. surveillance in Indonesia: the emergence or reemergence of S. dysenteriae.
