| adenoviruses in fecal samples from asymptomatic rhesus macaques, united states. | adenoviruses can cause infectious diarrheal disease or respiratory infections in humans; 2 recent reports have indicated probable human infection with simian adenoviruses (sadvs). to assess the possibility of animal-to-human transmission of sadvs, we tested fecal samples from asymptomatic rhesus macaques housed in 5 primate facilities in the united states and cultured 23 sadv isolates. of these, 9 were purified and completely sequenced; 3 sadv samples from the american type culture collection (s ... | 2012 | 22709783 |
| the role of human adenoviruses type 41 in acute diarrheal disease in minas gerais after rotavirus vaccination. | human adenovirus species f (hadv-f) type 40 and 41 are commonly associated with acute diarrheal disease (add) across the world. despite being the largest state in southeastern brazil and having the second largest number of inhabitants, there is no information in the state of minas gerais regarding the role of hadv-f in the etiology of add. this study was performed to determine the prevalence, to verify the epidemiological aspects of infection, and to characterize the strains of human adenoviruse ... | 2017 | 26887251 |
| longitudinal study on occurrence of adenoviruses and hepatitis a virus in raw domestic sewage in the city of limeira, são paulo. | the aim of this study was to verify the presence and annual distribution of adenoviruses and hepatitis a virus in domestic sewage in the city of limeira, são paulo. fifty samples with a volume of 8 liters each were collected weekly from december 2004 to december 2005. the viruses were concentrated by filtration through positively charged zp60s filter membranes, followed by ultracentrifugation. human adenoviruses (hadv) were detected by pcr followed by nested-pcr and screening for species f was d ... | 2009 | 24031326 |
| genomic copy concentrations of selected waterborne viruses in a slum environment in kampala, uganda. | the presence of viruses in a slum environment where sanitation is poor is a major concern. however, little is known of their occurrence and genomic copy concentration in the slum environment. the main objective of this study was to determine the genomic copy concentrations of human adenoviruses f and g, rotavirus (rv), hepatitis a virus (hav), hepatitis e virus (hev) and human adenovirus species a,c,d,e, and f (hadv-acdef) in bwaise iii, a typical slum in kampala, uganda. forty-one samples from ... | 2013 | 23708582 |
| construction of gene transfer vectors based on simian adenovirus 7. | the complete nucleotide sequence of an isolate of simian adenovirus 7 (sadv-7) was determined. the genome organization of this isolate was found to be similar to that of other primate adenoviruses with two principal notable points; severe truncation of the e1a and e1b 19k proteins and an e3 region encoding only the 12.5k homolog. the viral gene products of sadv-7 are most closely related to simian adenovirus 1 (sadv-1), and like sadv-1, are related to the human adenovirus species hadv-f, such as ... | 2011 | 21562118 |
| molecular identification of adenovirus causing respiratory tract infection in pediatric patients at the university of malaya medical center. | there are at least 51 adenovirus serotypes (adv) known to cause human infections. the prevalence of the different human adv (hadv) serotypes varies among different regions. presently, there are no reports of the prevalent hadv types found in malaysia. the present study was undertaken to identify the hadv types associated primarily with respiratory tract infections (rti) of young children in malaysia. | 2010 | 20594359 |
| complete genome sequence of simian adenovirus 1: an old world monkey adenovirus with two fiber genes. | simian adenovirus 1 (sadv-1) is one of many adenovirus strains that were isolated from old world monkey cells during poliomyelitis vaccine production several decades ago. despite the availability of these viruses, knowledge of their genetic content and phylogeny is rudimentary. in the present study, the genome sequence of sadv-1 (34,450 bp) was determined and analysed. in regions where genetic content varies between primate adenoviruses, sadv-1 has a single virus-associated rna gene, six genes i ... | 2005 | 15914845 |
| enteric viruses and adenovirus diversity in waters from 2016 olympic venues. | rio de janeiro's inner and coastal waters are heavily impacted by human sewage pollution for decades. enteric viruses, including human adenoviruses (hadv), human enterovirus (ev), group a rotavirus (rv) and hepatitis a virus (hav) are more likely to be found in contaminated surface waters. the present work aimed to assess the frequency and loads of ev, hadv-c and -f species, rv and hav in sand and water samples from venues used during the 2016 summer olympics and by tourists attending the event. ... | 2017 | 28185736 |
| quantitative pcr detection and characterisation of human adenovirus, rotavirus and hepatitis a virus in discharged effluents of two wastewater treatment facilities in the eastern cape, south africa. | the occurrence of enteric viruses in reclaimed wastewater, their removal by efficient treatment processes and the public health hazards associated with their release into the environments are of great significance in environmental microbiology. in this study, taqman-based real-time polymerase chain reaction (qpcr) was used to assess the prevalence of human adenovirus (hadv), rotavirus (rv) and hepatitis a virus (hav) in the final effluents of two wastewater treatment plants in the eastern cape p ... | 2016 | 27236707 |
| first evidence of a new simian adenovirus clustering with human mastadenovirus f viruses. | adenoviruses play an important role as human pathogens, though most infections are believed to be asymptomatic. the over 100 human adenovirus types are classified into seven species (a-g), some of which include simian adenoviruses. recent findings have highlighted that simian adenoviruses have a zoonotic potential and that some human adenoviruses are likely the result of relatively recent spillover events. | 2019 | 31775793 |
