| viral hepatitis. an important sexually transmitted disease. | hepatitis b is an important sexually transmitted disease. the availability of a safe and effective vaccine has unfortunately had little impact on controlling this disease nationwide or in north carolina, chiefly because target groups have proven difficult to reach. both hav and nanb can be transmitted sexually, but are much less important than hbv. | 1989 | 2710226 |
| detection of human enteric viruses in oysters by in vivo and in vitro amplification of nucleic acids. | this study describes the detection of enteroviruses and hepatitis a virus in 31 naturally contaminated oyster specimens by nucleic acid amplification and oligonucleotide probing. viruses were extracted by adsorption-elution-precipitation from 50-g oyster samples harvested from an area receiving sewage effluent discharge. ninety percent of each extract was inoculated into primate kidney cell cultures for virus isolation and infectivity assay. viruses in the remaining 10% of oyster extract that wa ... | 1996 | 8837433 |
| molecular epidemiology of foodborne hepatitis a outbreaks in the united states, 2003. | molecular epidemiologic investigations can link geographically separate foodborne hepatitis a outbreaks but have not been used while field investigations are in progress. in 2003, outbreaks of foodborne hepatitis a were reported in multiple states. | 2005 | 16170748 |
| recovery and sequence analysis of hepatitis a virus from springwater implicated in an outbreak of acute viral hepatitis. | an outbreak of acute hepatitis a virus in north carolina was linked to drinking water from a contaminated shallow spring by phylogenetic analysis of hepatitis a virus (hav) genomic sequences. detection of hav and fecal indicators in the water provided useful and timely information to assist with public health prevention and control measures. | 2008 | 18708522 |
