| viability of human adenovirus from hospital fomites. | the monitoring of environmental microbial contamination in healthcare facilities may be a valuable tool to determine pathogens transmission in those settings; however, such procedure is limited to bacterial indicators. viruses are found commonly in those environments and are rarely used for these procedures. the aim of this study was to assess distribution and viability of a human dna virus on fomites in an adult intensive care unit of a private hospital in rio de janeiro, brazil. human adenovir ... | 2014 | 25042068 |
| dissemination of gastroenteric viruses in the production of lettuce in developing countries: a public health concern. | investigation of major viruses responsible for acute viral gastroenteritis, such as norovirus (nov), rotavirus species a (rva) and human adenovirus (hadv), was conducted in the mountainous region of the state of rio de janeiro in a lettuce-producing area. irrigation water and lettuce samples were collected at different production stages. viruses were concentrated using an adsorption-elution method and detected by quantitative polymerase chain reaction (qpcr). we detected hadv in all collection p ... | 2017 | 28444305 |
| gastroenteric virus dissemination and influence of rainfall events in urban beaches in brazil. | this study was conducted to assess rotavirus a (rv-a), genogroup ii (gii) norovirus (nov), and human adenovirus (hadv) dissemination in recreational water in an urban beach located in the city of rio de janeiro and their persistence during rainfall events. | 2014 | 24980661 |
| assessment of burden of virus agents in an urban sewage treatment plant in rio de janeiro, brazil. | sewage discharge is considered to be the main source of virus contamination in aquatic environments. there is no correlation between the presence of viruses and the presence of fecal coliforms in water; therefore virological markers are needed when monitoring contamination. this study investigates dna and rna virus concentrations in wastewater and evaluates a potential virus marker of human contamination. influent and effluent samples were collected twice a month throughout a 1-year period. viru ... | 2013 | 23428554 |
| detection of enteric viruses in recreational waters of an urban lagoon in the city of rio de janeiro, brazil. | the aim of this study was to determine the occurrences of the group a rotavirus (rva), norovirus (nov) and human adenovirus (hadv) in the surface waters of an urban lagoon (rodrigo de freitas lagoon) in the city of rio de janeiro, brazil. during one year of surveillance, water samples were obtained from the lagoon and other interconnected ecosystems (river and beach). the samples were concentrated using an adsorption-elution method with a negatively charged membrane and tested by qualitative and ... | 2012 | 22990969 |
