| severe winter freezes enhance st. louis encephalitis virus amplification and epidemic transmission in peninsular florida. | mosquito-borne arboviral epidemics tend to strike without warning. the driving force for these epidemics is a combination of biotic (vector, amplification host, and virus) and abiotic (meteorological conditions, especially rainfall and temperature) factors. abiotic factors that facilitate the synchronization and interaction of vector and amplification host populations favor epidemic amplification and transmission. in florida, epidemics of st. louis encephalitis (sle) virus (family flaviviridae, ... | 2009 | 19960704 |
| avian serology in a st. louis encephalitis epicenter before, during, and after a widespread epidemic in south florida, usa. | blood and serum from 3,915 wild and domestic birds (2,590 resident, 139 migrant, and 1,186 captive), representing 56 species collected in central florida from 1989 through 1997, were analyzed for evidence of st. louis encephalitis (sle) virus transmission. all sera were tested for sle hemagglutination inhibition (hi) antibody. selected sera and bloods were tested for sle neutralizing (nt) antibody and virus. the reproductive success of resident birds was highest from 1990-1992 and lowest from 19 ... | 1999 | 10534957 |
