intestinal helminthic infections of cats in calabar, nigeria.a study of intestinal helminthic infections of 52 cats (felis catus) was undertaken in calabar, nigeria. direct smear and zinc sulphate floatation technique were utilized. the following helminths were observed: toxocara cati (28.85%), ancylostoma tubaeforme (19.23%), trichuris felis (5.77%), dipylidium caninum (23.08%) and taenia taeniaeformis (9.61%). the worm burdens were generally low, ranging from 2 to 20 per cat. no definite pattern of infection was observed with regard to sex. trematodes w ...19883169644
species-specific and common epitopes on the secreted and surface antigens of toxocara cati and toxocara canis infective larvae.it is widely accepted that the major cause of visceral larva migrans (vlm) in man is toxocara canis infection. this has been largely based on the detection of antibodies to this species. we have compared the antigens of t. canis and toxocara cati in order to establish whether assay for the former might be compromised by infection with the latter. comparisons were made by radioiodination of the surface and excretory/secretory (es) glycoproteins of the infective larvae of both species, immunopreci ...19872442693
ascarid infections of cats and dogs.the ascarids toxocara canis, toxocara cati, and toxascaris leonina are probably the most common gastrointestinal helminths encountered in small animal practice. both t. canis and t. cati can cause serious disease in kittens and puppies; t. leonina is generally less pathogenic. prenatal transmission assures that virtually all puppies are born infected with t. canis. transmammary transmission is probably the major route of infection for kittens with t. cati. in addition, all three species of worm ...19873328391
biochemical and immunological systematics of some ascaridoid nematodes: genetic divergence between congeners.vertical starch gel electrophoresis and trefoil immunodiffusion were used to study the systematics of some ascaridoid nematodes. within the ascarididae, the time scale of divergence was too great for intergeneric electrophoretic comparisons. congeneric electrophoretic comparisons of baylisascaris procyonis (host--raccoon) versus baylisascaris transfuga (host--black bear), and toxocara canis (host--domestic dog) versus toxocara cati (host--domestic cat) yielded nei genetic distance coefficients o ...19873114467
zoonotic helminths of dogs and cats at new bussa, kainji lake area, nigeria.a survey of the dog and cat population at new bussa revealed a significant high frequency of potential helminths of public health importance. this include hookworm ancylostoma spp.; echinococcus granulosa, dipylidium caninum in dog; and opisthorchis felineus, toxocara cati and capillaria hepatica in cat. the rural conditions of the area is an important factor in understanding the role cat and dog may play in spread of uncommon human parasites.19853833831
prevalence of chlamydia, toxoplasma, toxocara and ringworm in farm cats in south-west england.the prevalence of infection with chlamydia psittaci, toxoplasma gondii, toxocara cati and microsporum canis was examined in 51 cats on 22 sheep farms in the bristol area. serum antibody to c psittaci and t gondii was present in 45 per cent and 47 per cent of cats, respectively. at the time of sampling c psittaci was isolated from 6 per cent of the cats, t cati was identified in 63 per cent of faecal samples but neither t gondii nor m canis was isolated. when examined according to the farm of ori ...19873672827

improved method for recovering ascarid and other helminth eggs from soil associated with epizootics and during survey studies.two noncentrifugal and 5 centrifugal flotation methods for the recovery of infective baylisascaris procyonis eggs from contaminated soil were evaluated after an epizootic of fatal cerebrospinal nematodiasis in bobwhites. all involved the use of inexpensive, readily available materials and routine procedures. in all but 1 of the methods, sizes of the soil samples were 30 g; in 1 centrifugal method, the sample size was 1 g. the centrifugal methods included various combinations of (i) anionic deter ...19836683477
helminth parasites of wild cats in north-east scotland.three cestode species, namely taenia taeniaeformis batsch, 1786, taenia pisiformis (bloch, 1780) and mesocestoides litteratus (batsch, 1786) and one nematode species, toxocara cati schrank, 1788, were found in wild cats collected in grampian region, scotland. of the 41 cats examined, 25 were felis silvestris, 12 were feral felis catus and four were hybrids of f. silvestris and f. catus.19807229325
possible role of histamine in the genesis of pulmonary arterial disease in cats infected with toxocara cati.kittens between 12 and 20 weeks of age were orally dosed with 6000 infective ova of toxocara cati. animals were sacrificed at intervals between one and eight weeks after infection to study the development of pulmonary arterial lesions. after two weeks, marked leucocyte infiltration and mild thickening of the media of some of the smaller arteries was apparent histologically . cellular inflammatory activity progressively increased up to four weeks after infection when intimal proliferation was evi ...19846202045
toxoplasma gondii: transmission through feces in absence of toxocara cati eggs.when incubated at room temperature (23 degrees c) for 3 to 14 days, feces from cats infected 4 to 8 days with toxoplasma gondii, and free of toxocara cati eggs, produced toxoplasmosis in mice. results indicate that the nematode egg is not necessary for transmission of the parasite.19695813385
toxoplasma gondii: fecal forms separated from eggs of the nematode toxocara cati.cats excreted the protozoan toxoplasma gondii in feces, generally between 5 to 12 days after ingesting mice with chronic toxoplasmosis. toxoplasma gondii and eggs of the nematode toxocara cati occurring together could be separated by washing them through sieves that retained the eggs. this finding negates the postulated role of toxocara cati in the transmission of toxoplasmosis.19695813386
helminth species diversity and biology in the bobcat, lynx rufus (schreber), from nebraska.cestodes of 4 species and nematodes of 9 species were collected from 75 bobcats, lynx rufus (schreber), in nebraska from 1977 to 1979. of these 75, 11 were trapped from 6 border counties in 3 border states: south dakota, 7 carcasses/3 counties; kansas, 3/2; and wyoming, 1/1. helminths recovered included: mesocestoides corti hoeppli, 1925 (15% prevalence), taenia rileyi loewen, 1929 (67%), taenia pisiformis (bloch, 1780) gmelin, 1790 (27%), taenia macrocystis (diesing, 1850) lühe, 1910 (19%), phy ...19853998960
a survey of helminths in stray cats from copenhagen with ecological aspects.at autopsy of 230 adult stray cats, 120 from backyards and 110 from gardens, the intestinal tract was scrutinized for helminths. the prevalence of toxocara cati, taenia taeniaeformis and dipylidium caninum was found to be 79%, 11% and 14%, respectively. comparisons were made with the results of previous danish investigations. the prevalence of toxocara cati was found to be independent of time of collection and the sex and habitat of the cats and identical in cats with or without taenia. this ind ...19846538054
feline respiratory tract disease in louisiana.an investigation of feline respiratory tract disease (frd) was made involving 65 affected cats (group 1) and 65 control cats (group 2) matched for age, sex, and residence. feline calicivirus strains (fcv), feline herpesvirus-1 (fhv-1), or both, were isolated from 59% of group 1 cats and from 7% of group 2 cats. isolation of these viruses showed a significantly greater (p < 0.05) relative risk for group 1 cats. virus isolations were three times more frequent from males than from females older tha ...19806255833

[ascaridiasis zoonoses: visceral larva migrans syndromes].the syndrome of visceral larva migrans is a zoonotic disease due to the migration in human of nematodes larval, specially ascarid. since the larvae fail to complete their migrating cycle in humans, the diagnosis of toxocariasis infection remains only serologic. we have been able to demonstrate by the technique of agar diffusion and the western-blotting method that the etiology due to toxocara canis was twice as much frequent as the one due to toxocara cati in the syndrome of visceral and ocular ...19948076198
intestinal parasites of cats purchased in seoul.fecal samples of cats purchased in seoul were examined for helminth ova or protozoan oocysts from december 1987 to march 1988. out of the 41 samples, 31 (75.6%) were positive and 60 (146.3%) were cumulative positive for parasites. the followings were identified in the samples: eggs of toxocara cati, clonorchis sinensis, metagonimus sp., pharyngostomum cordatum, spirometra erinacei, taenia taeniaeformis and oocysts of isospora sp. from nine autopsied cats, larvae of anisakis simplex, adults of c. ...19938297895
pcr-based methods for identification of potentially zoonotic ascaridoid parasites of the dog, fox and cat.genomic dna was extracted from ascaridoid nematodes collected from dogs, foxes and cats. a region spanning the second internal transcribed spacer (its-2) of the ribosomal dna of each sample was amplified by pcr. representative its-2 products for each nematode species (toxocara canis, toxocara cati and toxascaris leonina) were sequenced. restriction sites were identified for use as genetic markers in a pcr-linked rflp assay. the three species could be differentiated from each other and from other ...19979386794
toxocara cati: hatching of second stage larvae.a method for hatching second-stage larvae of toxocara cati is described. whole adult worms are processed by centrifugation in the presence of hypochlorite which allows the grinding step to be eliminated. the technique is more rapid and a high yield is obtained.19979567507
hematology, intestinal parasites, and selected disease antibodies from a population of bobcats (felis rufus) in central arkansas.eight bobcats with adjoining or overlapping home ranges were examined. hematological values were within previously reported ranges. six bobcats demonstrated antibody titers to toxoplasma gondii. isospora spp., taenia taeniaeformis, spirometra mansoides, physoloptera rara, toxocara cati, strongyloides spp., trichurus spp., capillaria spp., and ancyclostoma spp. were found also in the animals examined. the mean number of parasite species per host was 4.1. all bobcats tested negative for serum anti ...19883352091
use of ivermectin in treatment of aelurostrongylus abstrusus and toxocara cati infection in a cat.ivermectin, administered at a rate of 200 micrograms/kg of body weight, sc, successfully removed toxocara cati infection from a young cat. a second treatment at a higher rate (400 micrograms/kg) was necessary to eliminate infection with the lungworm aelurostrongylus abstrusus. the drug apparently was tolerated well, and it appears to have several advantages over previously reported treatments for lungworm infections in cats.19873583886
evaluation of the efficacy and safety of two formulations of pyrantel pamoate in cats.the efficacy of paste and granule formulations of pyrantel pamoate against concurrent infections of toxocara cati and ancylostoma tubaeforme in cats was examined in a controlled trial. three groups of 8 cats received either no medication (controls) or pyrantel pamoate in paste or granule formulations at a dosage of 20 mg/kg of body weight. after administration of the paste formulation, fecal egg counts of a tubaeforme and t cati were decreased by 98.6 and 96.4%, respectively, and 100% of hookwor ...19902368952
toxocara canis: monoclonal antibodies to larval excretory-secretory antigens that bind with genus and species specificity to the cuticular surface of infective larvae.when maintained in culture, the infective-stage larvae of toxocara canis produce a group of excretory-secretory antigens. monoclonal antibodies to these antigens have been produced and partially characterized. hybridomas were made using spleens from mice that had been given 250 embryonated eggs of t. canis followed by immunization with excretory-secretory antigens. monoclonal antibodies were first screened against excretory-secretory antigens using an indirect enzyme-linked immunosorbent assay. ...19873315735
aspects of toxocara epidemiology: toxocarosis in dogs and cats.toxocara canis and toxocara cati are common roundworms of dogs and cats. in this review the life cycles of these parasites are described, including the various routes of transmission, such as transplacental, transmammary infection, and infection through paratenic hosts. the somatic and tracheal migration in the body of the hosts after infection with toxocara eggs or larvae is discussed, with special reference to age resistance and differences between dog and cat. the clinical symptoms and pathol ...19979347222
