| Molecular characterization of BK polyomavirus subtypes in renal transplant recipients in Brazil. | BK polyomavirus (BKV) is highly prevalent in the world population. Different reports indicate that BKV subtypes and subgroups present an uneven geographical distribution which might be correlated with human migration. However, there is a lack of data on the BKV subtype distribution in the South American population. The occurrence of BKV subtypes and subgroups detected in 51 kidney transplant recipients in Rio de Janeiro, Brazil is described. According to genetic studies, the population in this r ... | 2011 | 21678444 |
| molecular detection, quantification and characterization of human polyomavirus jc from waste water in rio de janeiro, brazil. | polyomavirus jc (jcpyv) is largely excreted by the human population through the urinary route and has been recognized as a potential viral marker for human waste contamination. this study aims to investigate the dissemination of jcpyv in waste water from a sewage treatment plant (stp) located in rio de janeiro, brazil, and to describe the prevalence of jcpyv subtypes currently present in this population. raw and treated sewage samples were collected bimonthly during one year, and examined for th ... | 2010 | 20375473 |
