| evaluation of argentinean bird species as amplifying hosts for st. louis encephalitis virus (flavivirus, flaviviridae). | st.louis encephalitis virus (slev) is an emerging human pathogen flavivirus in argentina. recently, it has reemerged in the united states. we evaluated the role as amplifying host of six resident bird species and analyzed their capacity as host during the 2005 encephalitis outbreak of slev in córdoba. eared dove, picui ground dove, and house sparrow were the three species with highest host competence index. at a city level, eared dove and picui ground dove were the most important amplifying host ... | 2018 | 29761767 |
| eared dove (zenaida auriculata, columbidae) as host for st. louis encephalitis virus (flaviviridae, flavivirus). | st. louis encephalitis virus (slev) is an emerging flavivirus in south american countries. its ecology and biological transmission cycles are scarcely known. eared doves (zenaida auriculata) have frequently been found infected by slev, and therefore, could be suspected as slev hosts. thirty post-hatch-year eared doves were subcutaneously inoculated with the genotype v slev 78v-6507 viral strain and subsequently bled. no deaths or clinical signs of illness were observed in the inoculated doves. t ... | 2008 | 18429694 |
| reemergence of st. louis encephalitis virus in the americas. | we summarize and analyze historical and current data regarding the reemergence of st. louis encephalitis virus (slev; genus flavivirus) in the americas. historically, slev caused encephalitis outbreaks in the united states; however, it was not considered a public health concern in the rest of the americas. after the introduction of west nile virus in 1999, activity of slev decreased considerably in the united states. during 2014-2015, slev caused a human outbreak in arizona and caused isolated h ... | 2018 | 30457961 |
| [molecular detection of saint louis encephalitis virus in mosquitoes in buenos aires]. | during march 2013 a population of eared doves (zenaida auriculata) was established in the center of city of buenos aires. considering the role of these birds as host competent for saint louis encephalitis virus (slev), a cdc light trap was put in place to perform entomologic surveillance. during this month 5 pools of mosquitoes (n = 48) were collected and taxonomically determined. three of them were classified as culex pipiens (n = 10) and the other two were culex spp. (n = 38). in this case, th ... | 2014 | 25555001 |
| activity patterns of st. louis encephalitis and west nile viruses in free ranging birds during a human encephalitis outbreak in argentina. | st. louis encephalitis virus (slev) (flavivirus) is a reemerging arbovirus in the southern cone of south america. in 2005, an outbreak of slev in central argentina resulted in 47 human cases with 9 deaths. in argentina, the ecology of slev is poorly understood. because certain birds are the primary amplifiers in north america, we hypothesized that birds amplify slev in argentina as well. we compared avian slev seroprevalence in a variety of ecosystems in and around córdoba city from 2004 (before ... | 2016 | 27564679 |
