| nesting ardeid colonies are not a focus of elevated west nile virus activity in southern california. | a large nesting colony of ardeid birds at the finney-ramer wildlife refuge in imperial county, california, did not appear to be a focus of west nile virus (wnv) amplification during the summer of 2004. blood samples taken during june and july from 155 nestlings of four species of ardeid birds (cattle egrets, black-crowned night herons, great egrets, and snowy egrets) and five nestling double-crested cormorants yielded a single wnv isolation from a 3-week-old cattle egret. antibody was detected b ... | 2005 | 16187895 |
| role of communally nesting ardeid birds in the epidemiology of west nile virus revisited. | although herons and egrets in the family ardeidae frequently have been associated with viruses in the japanese encephalitis virus serocomplex, communal nesting colonies do not appear to be a focus of early season and rapid amplification of west nile virus (wnv) in california. evidence for repeated wnv infection was found by testing living and dead nestlings collected under trees with mixed species ardeid colonies nesting above in an oak grove near the university of california arboretum in davis ... | 2009 | 19125659 |
| Mosquito host selection varies seasonally with host availability and mosquito density. | Host selection by vector mosquitoes is a critical component of virus proliferation, particularly for viruses such as West Nile (WNV) that are transmitted enzootically to a variety of avian hosts, and tangentially to dead-end hosts such as humans. Culex tarsalis is a principal vector of WNV in rural areas of western North America. Based on previous work, Cx. tarsalis utilizes a variety of avian and mammalian hosts and tends to feed more frequently on mammals in the late summer than during the res ... | 2011 | 22206038 |
