| molecular detection of circovirus and adenovirus in feces of fur seals (arctocephalus spp.). | in some regions, little is known about exposure to viruses in coastal marine mammals. the present study aimed to detect viral rna or dna in 23 free-ranging fur seals on the northern coastline of rio grande do sul state, brazil. polymerase chain reaction was used to detect nucleic acids of circoviruses, adenoviruses, morbilliviruses, vesiviruses, and coronaviruses in the feces from twenty-one south american fur seals (arctocephalus australis) and two subantarctic fur seals (a. tropicalis). adenov ... | 2017 | 27803979 |
| detection of human adenovirus, rotavirus and enterovirus in water samples collected on dairy farms from tenente portela, northwest of rio grande do sul, brazil. | viral gastroenteritis and other waterborne diseases are a major concern for health in brazil. a number of studies were conducted about the presence of viruses on water samples from brazilian areas. however, the knowledge about the occurrence of viral contamination of drinking water sources in rural settings of the country is insufficient. on the present work, 15 samples from 5 dairy farms located at the municipality of tenente portela were collected and analysed for the presence of human adenovi ... | 2013 | 24516464 |
| human adenovirus (hadv), human enterovirus (hev), and genogroup a rotavirus (garv) in tap water in southern brazil. | the effects of viral gastroenteritis are more devastating in children than in any other age category. thus, children exposed to the consumption of low quality water are at an increased risk of infection, especially in regions where sanitation is inadequate. the present study aimed to provide a survey of the occurrence of representative enteric viruses: human adenovirus (hadv), human enteroviruses (hev), and genogroup a rotavirus (garv) in tap water samples collected in public schools located at ... | 2014 | 25252356 |
| human adenovirus in tissues of freshwater snails living in contaminated waters. | human adenovirus (hadv) is resistant to environment and can be used as a marker to detect fecal contamination. considering the importance of freshwater snails in the aquatic environment, their use as concentrators for hadv is a complementary tool for viral analysis of water. the goal of the study was to detect hadv in snails and surface water collected from wetlands of the sinos river (rio grande do sul, brazil) basin and to compare rates and viral loads found in both samples. hadv was detected ... | 2017 | 28523581 |
| assessment of diversity of adenovirus dna polymerase gene in recreational waters facilitated by ultracentrifugal concentration. | adenoviruses (adv) are related to respiratory and gastrointestinal diseases in animals and human beings. their wide genetic diversity in water bodies and their resistance to environmental conditions allow the use of adv as a reliable marker for detection of fecal contamination. in this work, the diversity of adv along belo stream - in the city of caxias do sul, rio grande do sul, brazil - was evaluated. samples were compared in both concentrated and unconcentrated forms. the identification of di ... | 2018 | 29424724 |
