Derivation of a monoclonal antibody against the group specific antigen of rotaviruses and its use in a diagnostic enzymatic immunoassay. Human caliciviruses HuCVs are the most common cause calixivirus viral diarrhea outbreaks in adults and are mainly associated with consumption of water and contaminated seafood [ 1 ]. Recombinant Norwalk virus-like particles calicivkrus orally to volunteers: In summary, we have demonstrated that, in developing countries like Chile, HuCVs represent an important cause of acute sporadic gastroenteritis and that appropriate primers designed for local circulating strains significantly improve detection rates.

J Med Virol ; Anti-rotavirus Antibodies in Human Milk: In addition, we tested 80 samples from age-matched control children without diarrhea who presented to the ED from April through August Their role as a cause of gastroenteritis outbreaks in economically developing areas is unclear because little information is available 1 — 3. Comparative study of the acquisition of antibody to Norwalk virus in pediatric populations.

This study was approved by the ethics committee, Faculty of Medicine, University of Chile, and was developed under experimentation guidelines of the University of Chile.

These assays identified a total of 14 and 58 samples as rotavirus cakicivirus calicivirus positive respectively. These results suggest the non-circulation of both rotavirus and calicivirus within the Maternity Hospital.

This decline probably is a consequence of genetic variation that decreased the sensitivity of our RT-PCR, rather than a true decline in HuCV circulation; a demonstration of this hypothesis, however, will require future study.
