| epizootiology of haemoproteus danilewskyi (haemosporina: haemoproteidae) in blue jays (cyanocitta cristata) in southcentral florida. | prevalence and density of haemoproteus danilewskyi was studied in a population of free-ranging blue jays (cyanocitta cristata) in southcentral florida (usa) from may 1992 to december 1995. prevalence of infection was 27% for data combined over years, seasons, ages, and sexes. prevalence did not vary between sexes or among years, but increased with age and varied with season, being highest in june-july and lowest in november-january. parasite density did not vary between sexes or among seasons, b ... | 2003 | 12685063 |
| arboviral infection in two species of wild jays (aves: corvidae): evidence for population impacts. | we examined the prevalence of antibodies to three mosquito-borne arboviruses in blue jays, cyanocitta cristata, and florida scrub-jays, aphelocoma coerulescens, to identify the effects on host survival, the influence of sex and age on infection, and the temporal patterns of antibody prevalence. blood samples from 306 blue jays and 219 florida scrub-jays were collected at archbold biological station (lake placid, fl) from april 1994 through december 1995. sera were analyzed for hemagglutination-i ... | 2004 | 15061281 |
| mycoplasma sturni from blue jays and northern mockingbirds with conjunctivitis in florida. | northern mockingbirds (mimus polyglottos) and blue jays (cyanocitta cristata) in a florida (usa) wildlife care facility developed clinical signs and gross lesions suggestive of the ongoing outbreak of mycoplasma gallisepticum (mg) conjunctivitis in house finches (carpodacus mexicanus) and american goldfinches (carduelis tristis). mycoplasmal organisms were cultured from conjunctival/corneal swabs of birds with sinusitis, conjunctivitis, and/or epiphora. all of the isolates tested were identified ... | 1998 | 9577796 |
| arbovirus surveillance in florida: wild vertebrate studies 1965-1974. | wildlife species from 38 of florida's 67 counties were surveyed over a 10 year period for the presence of antibody to the five major arboviruses circulating in the state. the routine screening of 7891 sera from wild birds and mammals via the hemagglutination-inhibition (h1) test with selected reactors subjected to serum neutralization testing has 1) provided information regarding geographic distribution and seasonality of circulation of these viruses 2) identified enzootic foci of infection and ... | 1975 | 1152173 |
| ecology of culicoides (diptera: ceratopogonidae) in southcentral florida and experimental culicoides vectors of the avian hematozoan haemoproteus danilewskyi kruse. | to determine the vectors of haemoproteus danilewskyi in blue jays (cyanocitta cristata) in southcentral florida (usa), we conducted a 2 yr study from january 1993 to december 1995 of the presence and seasonal abundance of culicoides spp. of the 14 species of culicoides captured in centers for disease control light traps, 10 were ornithophilic. of these, c. edeni, c. knowltoni, c. stellifer, c. beckae, and c. arboricola were most abundant, representing 46% of the total collection and 99% of the o ... | 2003 | 12685081 |
