| prevalence and biology of endosymbionts of fleas (siphonaptera: pulicidae) from dogs and cats in alachua county, florida. | a study was conducted to determine the prevalence and biology of endosymbionts in local populations of fleas collected from dogs and cats in alachua co., florida. four hundred three ctenocephalides felis (bouché), 194 pulex simulans baker, and 44 echidnophaga gallinacea (westwood) were examined. fleas were collected from 52 dogs and 51 cats. from 1 to 20 fleas were dissected from each host. a variety of microorganisms and metazoa was observed, including a baculovirus, gram-negative bacteria, ric ... | 1990 | 2280390 |
| nolleria pulicis n. gen., n. sp. (microsporida: chytridiopsidae), a microsporidian parasite of the cat flea, ctenocephalides felis (siphonaptera: pulicidae). | a new species of microsporidium, nolleria pulicis, is described and named here from the cat flea, ctenocephalides felis. the genus nolleria is created and placed within the family chytridiopsidae. the family is slightly modified to accommodate certain features of intracellular development seen in n. pulicis, which is otherwise very similar to other species in the family chytridiopsidae. sporulation is described from ultrastructural analysis of infected midgut epithelial cells of adult c. felis. ... | 1990 | 2319492 |
| susceptibility of the cat flea (siphonaptera: pulicidae) to pyrethroids. | adult cat fleas, ctenocephalides felis felis (bouché), from two laboratory colonies (one originating in california and one from florida) were exposed to residues of eight pyrethroids to compare their susceptibilities. the florida strain was more tolerant than the california strain, with 6.8-, 5.2-, and 4.8-fold tolerance to cyfluthrin, cypermethrin, and fluvalinate, respectively. the florida strain showed less than 3-fold tolerance to the other five insecticides (permethrin, tralomethrin, d-phen ... | 1989 | 2754097 |
| the fleas (siphonaptera) of tennessee. | thirty-three species of fleas are recorded from the state of tennessee. new state records are reported for two species, the pulicid fleas euhoplopsyllus glacialis affinis and pulex simulans. two species of fleas with catholic feeding habits appear to be especially widespread and abundant in tennessee. these are the pulicid ctenocephalides felis which parasitizes cats, dogs, humans, opossums, and other medium to large sized mammals, and the hystrichopsyllid ctenophthalmus pseudagyrtes which is as ... | 1997 | 9221734 |
| outdoor survival and development of immature cat fleas (siphonaptera: pulicidae) in florida. | in north-central florida, cat flea, ctenocephalides felis felis bouché, larvae survived outdoors year round. their survival was greatest (up to 84.6%) outdoors in the fall, from september to november, when both temperatures and relative humidities were moderate. female cat fleas developed faster than males. development times for flea larvae were shortest (20-24 d) in june and july. from january to march, flea larval mortality was highest (91.7-100%) and development times the longest (36-50 d) ou ... | 1999 | 10083759 |
| insecticide susceptibilities of cat fleas (siphonaptera: pulicidae) from several regions of the united states. | eleven cat flea, ctenocephalides felis (bouchè), strains, seven field-collected and four laboratory-colonized, were assayed for susceptibilities to five insecticides (carbaryl, chlorpyrifos, malathion, permethrin, and pyrethrin) with an insecticide-treated, horizontally-oriented, nylon 6,6 disk in a test tube. the pyrethrin was synergized using piperonyl butoxide (pbo). flea mortality at two doses was recorded after 4 and 24 h exposures. the field strains from texas and florida tolerated carbary ... | 2002 | 12349857 |
| 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 |
| presence of bartonella species and rickettsia species dna in the blood, oral cavity, skin and claw beds of cats in the united states. | the purpose of this study was to determine the prevalence of bartonella species and rickettsia species dna in the blood, oral cavity, skin and claw beds of feral cats without evidence of skin disease that were housed in alabama (n = 24), florida (n = 27) and colorado (n = 32). samples were assessed by use of polymerase chain reaction assays. the bartonella species igg prevalence was also determined. while bartonella species dna was not amplified from any sample from colorado cats, it was commonl ... | 2009 | 20178489 |
