| isolations of yellow fever virus from haemagogus leucocelaenus in rio grande do sul state, brazil. | following howling monkey (alouatta caraya) deaths and yellow fever (yf) antigen detection by immunohistochemistry in the liver sample of a dead monkey in april and may 2001 in the municipalities of garruchos and santo antônio das missões, rio grande do sul state, brazil, epidemiological field investigations were initiated. two strains of yf virus were isolated in suckling mice from 23 haemagogus (conopostegus) leucocelaenus dyar & shannon mosquitoes collected from the study sites. the yf virus w ... | 2003 | 12892055 |
| reemergence of yellow fever: detection of transmission in the state of s+úo paulo, brazil, 2008. | following yellow fever virus (yfv) isolation in monkeys from the s+úo jos+® do rio preto region and two fatal human autochthonous cases from the ribeir+úo preto region, state of s+úo paulo, brazil, two expeditions for entomological research and eco-epidemiological evaluation were conducted. | 2011 | 21739073 |
| isolation of yellow fever virus from mosquitoes in misiones province, argentina. | yellow fever (yf) is a viral hemorrhagic fever endemic to tropical regions of south america and africa. from 2007 to 2009 an important epidemic/epizootic of yf was detected in different populations of howler monkeys (alouatta species) in misiones, a northeastern argentinian province. yellow fever virus (yfv) infection was researched and documented by laboratory tests in humans and in dead alouatta carayá. the objective of that research was to investigate the circulation of yfv in mosquitoes, whi ... | 2012 | 23025694 |
| host and viral traits predict zoonotic spillover from mammals. | the majority of human emerging infectious diseases are zoonotic, with viruses that originate in wild mammals of particular concern (for example, hiv, ebola and sars). understanding patterns of viral diversity in wildlife and determinants of successful cross-species transmission, or spillover, are therefore key goals for pandemic surveillance programs. however, few analytical tools exist to identify which host species are likely to harbour the next human virus, or which viruses can cross species ... | 2017 | 28636590 |
| impact of yellow fever outbreaks on two howler monkey species (alouatta guariba clamitans and a. caraya) in misiones, argentina. | two yellow fever outbreaks (yfos) occurred in northeastern argentina between november 2007 and october 2008, seriously affecting populations of two howler monkey species: the brown howler alouatta guariba clamitans and the black howler alouatta caraya. both howlers live syntopically in el piñalito provincial park, misiones, where four groups (36 individuals) were studied since january 2005. the first dead howlers were found on january 20, 2008, in el piñalito. systematic searches found 14 dead h ... | 2010 | 20095025 |
| Yellow fever outbreak affecting Alouatta populations in southern Brazil (Rio Grande do Sul State), 2008-2009. | The natural transmission cycle of Yellow Fever (YF) involves tree hole breeding mosquitoes and a wide array of nonhuman primates (NHP), including monkeys and apes. Some Neotropical monkeys (howler monkeys, genus Alouatta) develop fatal YF virus (YFV) infections similar to those reported in humans, even with minimum exposure to the infection. Epizootics in wild primates may be indicating YFV circulation, and the surveillance of such outbreaks in wildlife is an important tool to help prevent human ... | 2012 | 22020690 |
| circulation of antibodies against yellow fever virus in a simian population in the area of porto primavera hydroelectric plant, são paulo, brazil. | yellow fever (yf) is an acute viral infectious disease transmitted by mosquitoes which occurs in two distinct epidemiological cycles: sylvatic and urban. in the sylvatic cycle, the virus is maintained by monkey's infection and transovarian transmission in vectors. surveillance of non-human primates is required for the detection of viral circulation during epizootics, and for the identification of unaffected or transition areas. an elisa (enzyme-linked immunosorbent assay) was standardized for es ... | 2010 | 20305949 |
| global mammal parasite database version 2.0. | illuminating the ecological and evolutionary dynamics of parasites is one of the most pressing issues facing modern science, and is critical for basic science, the global economy, and human health. extremely important to this effort are data on the disease-causing organisms of wild animal hosts (including viruses, bacteria, protozoa, helminths, arthropods, and fungi). here we present an updated version of the global mammal parasite database, a database of the parasites of wild ungulates (artioda ... | 2017 | 28273333 |
