| ectoparasites of a population of urban gray squirrels in northern florida. | ectoparasites infesting a population of urban gray squirrels (sciurus carolinensis gmelin) in northern florida were collected monthly during 1974. eleven species were identified: one flea (orchopeas howardi (baker], three suckling lice (enderleinellus longiceps kellogg & ferris, hoplopleura sciuricola ferris, and neohaematopinus sciuri jancke), one tick (dermacentor variabilis say), two mesostigmatid (gamasid) mites (androlaelaps casalis (berlese) and a. fahrenholzi (berlese], and four chiggers ... | 1991 | 1875375 |
| parasites, diseases and health status of sympatric populations of sambar deer and white-tailed deer in florida. | from december 1983 to december 1984 a study on parasites, diseases and health status was conducted on sympatric populations of sambar deer (cervus unicolor) and white-tailed deer (odocoileus virginianus) from st. vincent island, franklin county, florida. ten sambar and six white-tailed deer were examined. white-tailed deer had antibodies to epizootic hemorrhagic disease virus and bluetongue virus. serologic tests for antibodies to the etiologic agents of bovine virus diarrhea, infectious bovine ... | 1987 | 3035242 |
| adaptions in the life cycle of dermacentor variabilis (say) and ixodes dammini (spielman, clifford, piesman, and corwin) marginal populations (acari: ixodidae). | both the dermacentor variabilis and ixodes dammini adult diapause seasons are followed by a breeding period. at the edge of the ticks' range, where diapause and breeding occur under adverse climatic conditions, the species still conserves its fixed response for the onset of diapause. as a result, most of the following breeding effort is wasted; the population can only be maintained by an aberrant breeding period during the normal diapause season. when the diapause and breeding periods are suitab ... | 1985 | 3916750 |
| ixodid ticks on feral swine in florida. | more than 99% of the 645 feral swine (sus scrofa l.) in southern florida harbored ixodid ticks. dermacentor variabilis (american dog tick) was present on 99.6% of the swine and comprised 82.5% of the ticks collected. amblyomma maculatum (gulf coast tick) occurred on 85.9% of the hosts and 17.4% of the collections were of this species. amblyomma americanum (lone star tick) and ixodes scapularis (black-legged tick) were found infrequently and together constituted less than 0.1% of the ticks. pigs ... | 1984 | 6737605 |
| evaluation of ixodes scapularis, amblyomma americanum, and dermacentor variabilis (acari: ixodidae) from georgia as vectors of a florida strain of the lyme disease spirochete, borrelia burgdorferi. | the ability of three common tick species from georgia to maintain and transmit the causative agent of lyme disease, borrelia burgdorferi, was compared under laboratory conditions. a b. burgdorferi cotton rat isolate (mi-6) from florida was selected as a strain from the south, and the sh2-82 isolate from new york was used as a positive control. amblyomma americanum (l.) and dermacentor variabilis (say) did not transmit the mi-6 isolate from inoculated hamsters to naive laboratory mice, and nympha ... | 1995 | 7650697 |
| parasitic arthropods of sympatric opossums, cotton rats, and cotton mice from merritt island, florida. | six species of parasitic arthropods were collected from 12 opossums (didelphis virginiana), 8 species were obtained from 28 cotton rats (sigmodon hispidus), and 4 species were collected from 10 cotton mice (peromyscus gossypinus) from merritt island, brevard county, florida. the flea polygenis gwyni was the only parasite that infested all 3 host species, and it was present in very high densities (mean intensity = 73.7) on the opossums. the american dog tick, dermacentor variabilis, and the tropi ... | 1993 | 8459341 |
| ixodid ticks from panthers and bobcats in florida. | ixodid ticks were present in all 189 samples examined from 53 florida panthers (felis concolor coryi, 104 collections) and 85 bobcats (felis rufus floridana) in florida (usa) between 1974 and 1991. we identified 3,251 ticks from panthers and 918 from bobcats. specimens of dermacentor variabilis, ixodes scapularis, i. affinis, amblyomma maculatum, and a. americanum were present on 49, 39, 17, seven, and two of the 53 florida panthers, respectively, and comprised 36%, 55%, 7%, 1%, and < 1% of the ... | 1995 | 8592378 |
| rodent ectoparasites from two locations in northwestern florida. | from feb.-apr. 1999, 19 species of ectoparasitic arthropods (2 sucking lice, 4 fleas, 4 ticks, 2 mesostigmatid mites, 5 chiggers, 2 fur mites) were recovered from 106 rodents belonging to 5 species (cotton mouse, peromyscus gossypinus, n = 64; cotton rat, sigmodon hispidus, n = 23; eastern woodrat, neotoma floridana, n = 9; golden mouse, ochrotomys nuttalli, n = 9; eastern gray squirrel, sciurus carolinensis, n = 1) at tall timbers research station, leon county, florida. during the same period, ... | 2000 | 11217221 |
| ixodid ticks on white-tailed deer and feral swine in florida. | a state-wide survey was conducted in florida during the 1997-99 hunting seasons to examine white-tailed deer (odocoileus virginianus) and feral swine (sus scrofa) for potential indigenous vectors of the rickettsial agent of heartwater, cowdria ruminantium. a total of 504 white-tailed deer and 166 feral swine was examined from 30 wildlife management areas across the state. amblyomma maculatum, an experimental vector of c. ruminantium, was common on both deer and feral swine throughout the state. ... | 2001 | 11469190 |
| major surface protein 1a effects tick infection and transmission of anaplasma marginale. | anaplasma marginale, an ehrlichial pathogen of cattle and wild ruminants, is transmitted biologically by ticks. a developmental cycle of a. marginale occurs in a tick that begins in gut cells followed by infection of salivary glands, which are the site of transmission to cattle. geographic isolates of a. marginale vary in their ability to be transmitted by ticks. in these experiments we studied transmission of two recent field isolates of a. marginale, an oklahoma isolate from wetumka, ok, and a ... | 2001 | 11730800 |
| prevalence of ectoparasites in a population of feral cats from north central florida during the summer. | ectoparasites are a common and important cause of skin disorders in cats. ectoparasites are capable of disease transmission and can cause life-threatening anemia in young or debilitated animals. the objective of this study was to determine the potential feline ectoparasites in domestic cats by using a cohort of feral cats from north central florida that have not received veterinary care and have no known exposure to insecticide application. a total of 200 feral cats were randomly selected for th ... | 2002 | 12383632 |
| seasonal distribution and abundance of ticks (acari: ixodidae) in northwestern florida. | a 2-yr study was conducted in a northwestern florida state park and recreation area to determine tick species composition, seasonal abundance, and spatial distribution. risk of tick attachment to park visitors was also assessed relative to tick abundance from several habitats. tick collections consisted of weekly cloth drag samples obtained from ground and emergent vegetation along a deer trail, a walking trail located in a 3-mo-old control burned area of forest, a nonburned walking trail, picni ... | 2000 | 15535590 |
| ticks and tick-borne pathogens and putative symbionts of black bears (ursus americanus floridanus) from georgia and florida. | ticks were collected from 38 black bears (ursus americanus floridanus) from northwestern florida (n = 18) from 2003 to 2005 and southern georgia (n = 20) in 2006. five species (amblyomma americanum, a. maculatum, dermacentor variabilis, ixodes scapularis, and i. affinis) were collected from florida bears, and 4 species (a. americanum, a. maculatum, d. variabilis, i. scapularis) were collected from bears in georgia. ixodes scapularis was the most frequently collected tick, followed by d. variabil ... | 2009 | 19413369 |
| distribution and prevalence of cytauxzoon felis in bobcats (lynx rufus), the natural reservoir, and other wild felids in thirteen states. | cytauxzoon felis, a protozoan parasite of wild and domestic felids, is the causative agent of cytauxzoonosis in domestic and some exotic felids in the united states. the bobcat (lynx rufus) is the natural reservoir for this parasite, but other felids such as florida panthers (puma concolor coryii) and domestic cats may maintain long-term parasitemias and serve as reservoirs. experimentally, two tick species, dermacentor variabilis and amblyomma americanum, have demonstrated the ability to transm ... | 2010 | 21071149 |
