colic surgery in 206 juvenile thoroughbreds: survival and racing results.the purpose of our study was to determine the types of lesions that cause colic in juvenile thoroughbreds, factors associated with these lesions and the subsequent survival and athletic performance of the juveniles. the age of juvenile thoroughbreds requiring surgical exploration for abdominal pain has an influence on the type of lesion causing colic. the short-term survival rate (discharge from the hospital) after colic surgery for foals was 85% and was strongly influenced by the lesion causing ...200011202379
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 ...200415061281

venezuelan equine encephalitis virus infection of cotton rats.venezuelan equine encephalitis virus (veev) is an emerging pathogen of equids and humans, but infection of its rodent reservoir hosts has received little study. to determine whether responses to infection vary among geographic populations, we inoculated 3 populations of cotton rats with 2 enzootic veev strains (co97-0054 [enzootic id subtype] and 68u201 [enzootic ie subtype]). the 3 populations were offspring from wild-caught cotton rats collected in a vee-enzootic area of south florida, usa; wi ...200717953085
ciguatera fish poisoning in the caribbean islands and western atlantic.ciguatera fish poisoning (ciguatera), a common poisoning caused by fish ingestion, is reviewed in the western atlantic and the caribbean waters. it is endemic from florida coasts (northern limit) to martinique island (southern limit), with outbreaks occurring from time to time. in the caribbean, ciguatera causes a polymorphic syndrome with gastrointestinal, cardiovascular, and neurological signs and symptoms. neurological and muscular dysfunctions can be treated by intravenous injection of d-man ...200112882228

equestrian injuries in children.equestrian activities are regarded by some as high-risk sports, and our recent experience suggested this to be true. we undertook this study to review our experience with pediatric equestrian injuries.200919159733
west nile virus activity--united states, september 29-october 5, 2004.during september 29-october 5, a total of 81 cases of human west nile virus (wnv) illness were reported from 18 states (alabama, arizona, arkansas, california, florida, georgia, illinois, iowa, kansas, kentucky, minnesota, missouri, ohio, oklahoma, pennsylvania, south dakota, texas, and virginia).200415470326
Seasonal abundance of stable flies and filth fly pupal parasitoids (Hymenoptera: Pteromalidae) at Florida equine facilities.Beginning in November 2007 and continuing until December 2009, weekly stable fly, Stomoxys calcitrans (L.), surveillance was conducted at four equine facilities near Ocala, FL, by using alsynite sticky traps for adults and by searching immature developmental sites for pupae. Adult stable fly trap captures were highly variable throughout the year, ranging from 0 to 1,400 flies per trap per farm. The greatest adult stable fly activity was observed during the spring months of March and April, with ...201121735936
combined keratectomy, strontium-90 irradiation and permanent bulbar conjunctival grafts for corneolimbal squamous cell carcinomas in horses (1990-2002): 38 horses.the purpose of this study was to evaluate the effectiveness of postoperative beta-irradiation with strontium-90 as an adjunctive treatment to superficial keratectomy and permanent bulbar conjunctival graft for removal of equine corneolimbal squamous cell carcinoma (scc), in decreasing recurrence rate.200717204126
health concerns of migrant backstretch workers at horse racetracks.backstretch workers are part of an itinerant labor community that cares for horses at racetracks across the u.s. since the 1970s, this workforce has increasingly been composed of migrants, especially from mexico and guatemala. no studies have focused systematic attention on health concerns of this population and how illness is influenced by unique working and living conditions.201020453352

the ability of selected pupal parasitoids (hymenoptera: pteromalidae) to locate stable fly hosts in a soiled equine bedding substrate.the ability of spalangia cameroni perkins, spalangia endius walker, and muscidifurax raptorellus kogan and legner to locate and attack stable fly hosts was evaluated under laboratory conditions. postfeeding third-instar stable fly larvae were released and allowed to pupate in two arena types: large 4.8 liter chambers containing a field-collected, soiled equine bedding substrate; or 120-ml plastic cups containing wood chips. at the time of fly pupariation, parasitoids were released and permitted ...201122182616

assessing permethrin resistance in the stable fly (diptera: muscidae) in florida by using laboratory selections and field evaluations.insecticide resistance in the stable fly, stomoxys calcitrans (l.) (diptera: muscidae),has been demonstrated previously, but mostly with insecticides that are no longer used, such as the organochlorines. resistance to commonly used pyrethroids has been evaluated twice, but only in the midwestern united states. stable fly susceptibility to a commonly used pyrethroid, permethrin, was determined in florida to assess the possibility of resistance development. diagnostic concentration evaluations of ...201021309252
a microsatellite analysis of five colonial spanish horse populations of the southeastern united states.the domestic horse (equus caballus) was re-introduced to the americas by spanish explorers. although horses from other parts of europe were subsequently introduced, some new world populations maintain characteristics ascribed to their spanish heritage. the southeastern united states has a history of spanish invasion and settlement, and this influence on local feral horse populations includes two feral-recaptured breeds: the florida cracker and the marsh tacky, both of which are classified as col ...201222221025
phylogenetic analysis of eastern equine encephalitis virus isolates from florida.abstract. florida has the highest degree of endemicity for eastern equine encephalitis virus (eeev) of any state in the united states and is the only state with year-round transmission of eeev. to further understand the viral population dynamics in florida, the genome sequence of six eeev isolates from central florida were determined. these data were used to identify the most polymorphic regions of the eeev genome from viruses isolated in florida. the sequence of these polymorphic regions was th ...201121540379
