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 ...19902280390
factors affecting the development of dipylidium caninum in ctenocephalides felis felis (bouché, 1835).ctenocephalides felis felis larvae were infected with dipylidium caninum at a range of temperatures from 20 degrees - 35 degrees c at 3 mm hg saturation deficit (sd) and 30 degrees c at 8 mm hg sd. hosts were subsequently dissected at 6, 9 and 12 days after infection. four replicate experiments were performed and results of development, and host reactions analysed by the genstat computer programme. these were found to depend on the temperature and saturation deficit of the environment. unlike pr ...19854082734
helminth parasites and arthropods of feral cats.the prevalence (%) of helminth parasites in 327 mainly adult feral cats from 3 habitat groupings in victoria and new south wales was determined. the cestodes taenia taeniaeformis (33%) and spirometra erinacei (33%) were common; dipylidium caninum was rate (2%). the nematodes toxocara cati (28%), cyathospirura dasyuridis and cylicospirura felineus combined (27%) and aelurostrongylus abstrusus (14%) were common but their prevalence differed markedly between habitats. ollulanus tricuspis (5%), gnat ...19817340783
endosymbionts of ctenocephalides felis felis (siphonaptera: pulicidae) obtained from dogs captured in belo horizonte, minas gerais, brazil.specimens of fleas ctenocephalides felis felis (1052 female symbol/448 male symbol), obtained from 150 dogs in centro de controle de zoonoses de belo horizonte, minas gerais, brazil, were dissected and examined for endosymbionts. three protozoan, nolleria pulicis, a gregarine (actinocephalidae) and leptomonas sp., together with one cestode, dipylidium caninum were identified. infections by n. pulicis and leptomonas sp. occurred mainly in the warm-rainy period. the prevalence and distribution of ...200717113100
gastrointestinal and ectoparasites from urban stray dogs in fortaleza (brazil): high infection risk for humans?dogs are important definite or reservoir hosts for zoonotic parasites. however, only few studies on the prevalence of intestinal parasites in urban areas in brazil are available. we performed a comprehensive study on parasites of stray dogs in a brazilian metropolitan area. we included 46 stray dogs caught in the urban areas of fortaleza (northeast brazil). after euthanization, dogs were autopsied. ectoparasites were collected, and the intestinal content of dogs were examined for the presence of ...201020532563
comparative in vivo adulticidal activity of a topical dinotefuran versus an imidacloprid-based formulation against cat fleas (ctenocephalides felis) on cats.fleas cause significant discomfort to pet cats and distress to their owners and are also vectors of disease severe infestations can cause anemia or flea allergy dermatitis and can lead to infections with dipylidium caninum and bartonella henselae. rapid flea kill is an important feature of flea preventives. the efficacy of dinotefuran (vectra for cats and kittens, summit vetpharm) was compared with that of imidacloprid (advantage, bayer animal health) against ctenocephalides felis when applied t ...200919742443
effects on the development of dipylidium caninum and on the host reaction to this parasite in the adult flea (ctenocephalides felis felis).temperature was found to be a major factor affecting the development of dipylidium caninum and the presence of a host reaction of adult ctenocephalides felis felis to d. caninum. adult fleas reared at 30-32 degrees c contained fully developed metacestodes when they emerged from their cocoons. however at lower temperatures, d. caninum could not complete development until the flea hosts had spent some time on their mammalian hosts. it was the surface temperature of the mammals (31-36 degrees c) an ...19873575292
a survey of cats and dogs for fleas: with particular reference to their role as intermediate hosts of dipylidium caninum.three species of fleas, viz. ctenocephalides felis, ctenocephalides canis, and pulex irritans were found in an examination of 81 cats and 48 dogs in wellington. c. felis was the most prevalent flea in cats, and c. canis predominated in dogs. it is speculated that c. felis, and its primary host the cat, may assume greater medical and veterinary significance than c. canis. in an examination of 1578 fleas for cysticercoids of the dog tapeworm, dipylidium caninum, all were found negative. these resu ...198416031050
[the biology of dipylidium caninum. part 2].from 198 cats and 182 dogs in austria 9,134 fleas were collected. ctenocephalides felis is the main flea of our cats (98.5%) and dogs (77.5%). demonstration of cysticercoids of dipylidium caninum through bleaching of fleas failed. dissection of fleas gave, however, positive results. each 44th flea from cats and 61st flea from dogs harbours cysticercoids. infection intensity rates were 2.3% for c. felis (cats), 1.2% for c. felis (dogs), and 3.1% for c. canis (dogs). male fleas are more extensivel ...19911927147
