| a retrospective study of proliferative interstitial lung disease of horses in florida. | proliferative and fibrosing interstitial lung disease was diagnosed in 20 horses submitted for necropsy between 1982 and 1985. most of the horses were foals ranging from 3 days to 6 months in age. six adult horses were affected. the macroscopic and microscopic characteristics of the lesions consisted of proliferative interstitial pneumonia and were similar to those of atypical interstitial pneumonia of ruminants. based on morphologic features of the lesions, a toxic etiology is suspected for the ... | 1986 | 3811140 |
| laboratory vector competence of culex (melanoconion) cedecei for sympatric and allopatric venezuelan equine encephalomyelitis viruses. | laboratory vector competence of culex (melanoconion) cedecei was examined for venezuelan equine encephalomyelitis (vee) viruses. colonized adult female mosquitoes originating from a southern florida population were given bloodmeals from viremic hamsters circulating various titers of 3 hemagglutination inhibition (hi) subtypes of vee viruses. following extrinsic incubation of about 3 weeks, mosquitoes were allowed to refeed on uninfected hamsters for transmission trials. cx. cedecei was highly ef ... | 1986 | 3706626 |
| clinical, clinicopathologic, and epidemiologic features of anhidrosis in central florida thoroughbred horses. | a group of 834 thoroughbred horses was surveyed on four central florida farms for clinical and epidemiologic features of anhidrosis. in addition, comparative analysis was made of serum thyroxine, serum electrolytes, and fractional urinary electrolyte excretion ratios. an overall disease prevalence of 6.12% was observed. training horses and nonpregnant broodmares had a predilection for the disease. adolescent horses were infrequently affected. there was no correlation with sex or color. comparati ... | 1987 | 3506097 |
| equine culicoides hypersensitivity in florida: biting midges collected in light traps near horses. | twenty-three species of culicoides were trapped near pruritic horses during a 2-year survey in florida. nearly 99% of the biting midges collected were represented by culicoides insignis lutz, c. edeni wirth and blandon, c. stellifer (coquillett), c. niger root and hoffman, c. haematopotus malloch and c. venustus hoffman. the relative contribution to the total catch by each of these species varied among collection sites. seasonally, different species attain their largest population sizes at diffe ... | 1988 | 2980168 |
| identification of highlands j virus from a florida horse. | a virus, strain 64a-1519, isolated from the brain of a horse dying of encephalitis in florida in 1964, was identified as western equine encephalomyelitis (wee) virus. recently, we used polyclonal and monoclonal immune reagents to identify this isolate by comparing it to 2 strains of wee virus and to highlands j (hj) virus in hemagglutination-inhibition, immunofluorescent antibody, and plaque-reduction neutralization tests. these tests demonstrate that strain 64a-1519 is a strain of hj virus dist ... | 1988 | 2849884 |

| isolation of eastern equine encephalitis virus from aedes albopictus in florida. | fourteen strains of eastern equine encephalitis (eee) virus were isolated from aedes albopictus mosquitoes collected in polk county, florida. these are the first isolations of an arbovirus of proven public health and veterinary importance from naturally infected ae. albopictus in the united states since established populations of this introduced mosquito were first discovered in 1985. the widespread distribution of ae. albopictus in florida and in other areas of the united states where eee is en ... | 1992 | 1321985 |
| comparison of chickens and pheasants as sentinels for eastern equine encephalitis and st. louis encephalitis viruses in florida. | pheasants and chickens were compared as sentinels for monitoring the transmission of arboviruses of public health significance in florida during 1991-93. results suggest that pheasants are better sentinels for eastern equine encephalitis (eee) virus. they detected virus transmission 3-6 weeks earlier in epizootic years, 2-4 times more frequently during the season, and twice as many birds within a flock seroconverted during a given week. pheasants detected virus transmission at 2 sites during 2 i ... | 1994 | 7707062 |
| experimental transmission of eastern equine encephalitis virus by strains of aedes albopictus and a. taeniorhynchus (diptera: culicidae). | the vector competence of aedes taeniorhynchus (wiedemann) and four strains of aedes albopictus (skuse) was assessed for eastern equine encephalitis (eee) virus isolated from ae. albopictus collected in polk county, florida. both species became infected with and transmitted eee virus by bite after feeding on 1-d-old chicks that had been inoculated with eee virus (viremia = 10(10.1) plaque-forming units [pfu] per ml of blood). however, when fed on an older chick with a lower viremia (viremia = 10( ... | 1994 | 8189419 |

| diverged evolution of recent equine-2 influenza (h3n8) viruses in the western hemisphere. | we reported previously that equine-2 influenza a virus (h3n8) had evolved into two genetically and antigenically distinct "eurasian" and "american" lineages. phylogenetic analysis, using the ha1 gene of more recent american isolates, indicated a further divergence of these viruses into three evolution lineages: a south american lineage, a kentucky lineage, and a florida lineage. these multiple evolution pathways were not due to geographic barriers, as viruses from different lineages co-circulate ... | 2001 | 11504416 |
| seasonal abundance of culex nigripalpus theobald and culex salinarius coquillett in north florida, usa. | north florida is a transition zone between widespread culex nigripalpus populations to the south and focal culex salinarius populations to the north. culex nigripalpus is a vector of st. louis encephalitis (sle) and eastern equine encephalitis (eee) viruses in south florida, while cx. salinarius is a suspected new world vector of west nile (wn) virus. abundant vector populations are often a prerequisite for epidemic and epizootic transmission of arboviruses. extensive sle transmission has never ... | 2002 | 12125867 |
