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 ...19979221734
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 ...200212383632
techniques of dna-studies on prehispanic ectoparasites (pulex sp., pulicidae, siphonaptera) from animal mummies of the chiribaya culture, southern peru.during a paleoparasitological survey of several animal mummies (cavia aperea f. porcellus and canis familiaris) from chiribaya baja, an archaeological site in southern peru, an unexpected find was made. in the well preserved fur, large numbers of mummified fleas (pulex simulans/irritans) that parasitized the animals during life were encountered. due to the relative recent event of the host mummification and the outstanding preservation of the fleas, an attempt for the retrieval of dna was made. ...200312687763
wolbachia endosymbionts in fleas (siphonaptera).intracellular endosymbionts, wolbachia spp., have been reported in many different orders of insects and in nematodes but not previously in fleas. this is the first conclusive report of wolbachia spp. within members of the siphonaptera. using nested polymerase chain reaction (pcr) targeting of the 16s ribosomal rna gene, we screened for wolbachia spp. in fleas collected from 3 counties in georgia and 1 in new york. the prevalence of wolbachia spp. detected varied among the 6 different species scr ...200312760642

fleas parasitizing domestic dogs in georgia, usa: species composition and seasonal abundance.monthly flea collections were made from domestic dogs in bulloch county, georgia, usa from september 1996 to august 2004. a total of 2518 fleas belonging to 8 species were collected. the most common flea was the cat flea, ctenocephalides felis (389 males and 1148 females), followed by the dog flea, ctenocephalides canis (250 males and 285 females), a generalist/carnivore flea, pulex simulans (106 males and 213 females), and a sticktight flea, echidnophaga gallinacea (3 males and 89 females). sma ...200515893082
possible vector dissemination by swift foxes following a plague epizootic in black-tailed prairie dogs in northwestern texas.to determine whether swift foxes (vulpes velox) could facilitate transmission of yersinia pestis to uninfected black-tailed prairie dog (cynomys ludovicianus) colonies by acquiring infected fleas, ectoparasite and serologic samples were collected from swift foxes living adjacent to prairie dog towns during a 2004 plague epizootic in northwestern texas, usa. a previous study (1999-2001) indicated that these swift foxes were infested almost exclusively with the flea pulex irritans. black-tailed pr ...200616870868
zoonotic bartonella species in fleas collected on gray foxes (urocyon cinereoargenteus).bartonella spp. are fastidious, gram-negative, rod-shaped bacteria and are usually vector-borne. however, the vector has not been definitively identified for many recently described species. in northern california, gray foxes (urocyon cinereoargenteus) are infected with two zoonotic bartonella species, b. rochalimae and b. vinsonii subsp. berkhoffii. fleas (range 1-8 fleas per fox) were collected from 22 (41.5%) of 54 gray foxes from urban and backcountry zones near hoopa, california. the flea s ...200919125660

mammalian hosts, vectors, and bacterial pathogens in communities with and without black-tailed prairie dogs ( cynomys ludovicianus) in northwestern mexico.:  the presence of keystone species can influence disease dynamics through changes in species diversity and composition of vector and host communities. in this study, we compared 1) the diversity of small mammals; 2) the prevalence, abundance, and intensity of arthropod vectors; and 3) the prevalence of yersinia pestis, francisella tularensis, and bartonella spp. in vectors, between two grassland communities of northern sonora, mexico, one with (la mesa [lm]) and one without (los fresnos [lf]) b ...201829059012
flea (pulex simulans) infestation in captive giant anteaters (myrmecophaga tridactyla).a pair of captive adult giant anteaters (myrmecophaga tridactyla) presented heavily infested with a flea species (pulex simulans) commonly found on virginia opossums (didelphis virginiana) and raccoons (procyon lotor) in the central united states. in this case, the flea was demonstrated to have completed its entire life cycle with the anteaters as the host. a single treatment of topical imidacloprid, coupled with removal and replacement of infested bedding, was rapidly effective at controlling t ...200617319150
ectoparasites of dogs in home environments on the caribbean slope of costa rica.reports on ectoparasites on dogs in central america are scarce. the aim of this study was to identify flea, louse and tick species infesting dogs in home environments on the caribbean slope of costa rica, and determine their frequency and coexistence. ectoparasites were collected from dogs in 83 rural homes at five study sites. specimens were identified and separated according to species. fleas were the most common ectoparasite (g = 22,217, df = 8, p = 0.004). ctenocephalides felis and pulex sim ...201322832763
detection of rickettsiae in fleas and ticks from areas of costa rica with history of spotted fever group rickettsioses.outbreaks of spotted fevers have been reported in costa rica since the 1950s, although vectors responsible for transmission to humans have not been directly identified. in this study, species of rickettsia were detected in ectoparasites from costa rica, mostly from five study sites where cases of spotted fevers have been reported. ticks and fleas were collected using drag cloths or directly from domestic and wild animals and pooled according to species, host, and location. pools were analyzed in ...201627592065
prevalence and phylogenetic analysis of bartonella species of wild carnivores and their fleas in northwestern mexico.the host-parasite-vector relationship of bartonella spp. system in wild carnivores and their fleas from northwestern mexico was investigated. sixty-six carnivores belonging to eight species were sampled, and 285 fleas belonging to three species were collected during spring (april-may) and fall (october-november) seasons. we detected bartonella species in 7 carnivores (10.6%) and 27 fleas (9.5%) through either blood culture or pcr. of the 27 bartonella-positive fleas, twenty-two were pulex simula ...201728197898
molecular detection of bartonella species in fleas collected from dogs and cats from costa rica.the bacterial genus bartonella includes several species with zoonotic potential, some of which are common in domestic dogs and cats, as well as in their fleas. because there is no previous information about the presence of bartonella species in fleas from central america, this study aimed at evaluating the presence of bartonella spp. in fleas collected from dogs and cats in costa rica. a total 72 pools of ctenocephalides felis and 21 pools of pulex simulans were screened by conventional pcr to d ...201526393956
flea abundance on black-tailed prairie dogs (cynomys ludovicianus) increases during plague epizootics.black-tailed prairie dogs (cynomys ludovicianus) on the great plains of the united states are highly susceptible to plague, caused by the bacterium yersinia pestis, with mortality on towns during plague epizootics often approaching 100%. the ability of flea-borne transmission to sustain disease spread has been questioned because of inefficiency of flea vectors. however, even with low individual efficiency, overall transmission can be increased if flea abundance (the number of fleas on hosts) inc ...200919492944
the potential role of swift foxes (vulpes velox) and their fleas in plague outbreaks in prairie dogs.swift foxes (vulpes velox) have been proposed as potential carriers of fleas infected with the bacterium yersinia pestis between areas of epizootics in black-tailed prairie dogs (cynomys ludovicianus). we examined antibody prevalence rates of a population of swift foxes in colorado, usa, and used polymerase chain reaction (pcr) assays to examine their flea biota for evidence of y. pestis. fifteen of 61 (24%) captured foxes were seropositive, and antibody prevalence was spatially correlated with ...200717699080
ectoparasites of free-ranging pumas and jaguars in the paraguayan chaco.ectoparasites were collected from seven puma (puma concolor) and seven jaguar (panthera onca) live-captures (each representing six different animals) in the paraguayan chaco from 2002 to 2004. the same five species of ectoparasites were recovered from both host species: the flea, pulex simulans (total on both hosts combined=30 male, 49 female), and the ticks, amblyomma cajennense (1 male, 4 female, 46 nymphs, 241 larvae), amblyomma parvum (42 male, 25 female), amblyomma tigrinum (1 male, 7 femal ...200616464533
genetic and phylogeographic structure of populations of pulex simulans (siphonaptera) in peru inferred from two genes ( cytb and coii).in this paper we discuss the potential usefulness of determining the phylogeographic and phylogenetic patterns of a vector for understanding the spread of pathogens or insecticide resistance. we do so using the example of pulex simulans in peru. six populations from six different localities were investigated. mitochondrial dna sequences were obtained and branching patterns were inferred using phylogenetic reconstruction methods and nested clade analyses. ten different haplotypes were discovered. ...200312884014
prevalence of the generalist flea pulex simulans on black-tailed prairie dogs (cynomys ludovicianus) in new mexico, usa: the importance of considering imperfect detection.if a parasite is not detected during a survey, one of two explanations is possible: the parasite was truly absent or it was present but not detected. we fit occupancy models to account for imperfect detection when combing fleas (siphonaptera) from black-tailed prairie dogs (cynomys ludovicianus) during june-august 2012 in the vermejo park ranch, new mexico, usa. with the use of detection histories from combing events during monthly trapping sessions, we fit occupancy models for two flea species: ...201525588009
