To the Editor: We read with great interest the article on human norovirus (hNoV) by Straub et al. (1). By using 3-dimensional aggregates of a highly differentiated intestinal epithelial cell line, the investigators claimed to have established an in vitro cell culture model that “support[s] the natural growth of human noroviruses.” While the authors provide compelling evidence of successful viru...
aim : the aim of this study is to determine the prevalence and genotype of human caliciviruses among children suffering from acute gastroenteritis referred to masih daneshvari hospital. background : human caliciviruses have been recognized as the major viral cause of acute gastroenteritis in all age groups worldwide. studies revealed that the noroviruses and sapoviruses could be divided into fi...
Noroviruses (NoV) in 78 wastewater samples from Luxembourg were quantified, cloned, and sequenced in 2008-2009. The concentrations of NoV genogroup II and the relative occurrences of certain genotypes changed significantly during the winter season. NoV genogroup I was frequently detected by real-time reverse transcription-PCR (RT-PCR), albeit at 30-fold lower concentrations than for genogroup I...
We determined a structure of a bovine (genogroup III, GIII) norovirus capsid protruding (P) domain using X-ray crystallography. The bovine P domain was reminiscent of other norovirus genogroups (GI, GII, GIV, and GV), but closely matched the human GI P domain. We also identified a monoclonal antibody that was capable of binding the five different (GI-GV) P domains. Our data suggests that geneti...
Noroviruses (NoVs) are increasingly being recognized as important enteric pathogens. At a university-based hospital, we investigated a nosocomial outbreak of NoV infection that was originally attributed to Clostridium difficile. We describe here the unique challenges of the identification of NoVs as the true etiologic pathogen in an outbreak occurring in a health care setting, where C. difficil...
