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
[chronic gastritis caused by ollulanus tricuspis (leuckart, 1865) in a tiger].a chronic gastritis caused by an infestation with o. tricuspis is described. the differential-diagnostic importance of this parasitosis in chronic maldigestive diseases is emphasized. conventional coproscopic diagnostic procedures fail as the life cycle of the parasite is confined to the gastrum of the host.19938457185
[investigations on the endoparasitic fauna of domestic cats in eastern brandenburg].the internal organs of 155 cats originating from 3 different territories in the eastern part of brandenburg state were examined for parasites between 1993 and 1995. parasites were found in 85% of cats. parasites with the highest prevalence were toxocara mystax (45%), hydatigera taeniaeformis (22%), ancylostoma tubaeforme (17%) and opisthorchis felineus (16%). metorchis bilis, mesocestoides spp., taenia pisiformis, capillaria plica, capillaria sp., ollulanus tricuspis, aelurostrongylus abstrusus, ...19979139627
a survey of helminth parasites of cats from saskatoon.in a survey of 52 cats from the saskatoon area, ollulanus tricuspis were found in 2 animals with burdens of 2308 and 533, respectively. small burdens of the following helminths were also found: physaloptera spp., toxocara cati, taenia spp., dipylidium caninum, and ancylostoma sp.199910340095
gastric ollulanus tricuspis infection identified in captive cheetahs (acinonyx jubatus) with chronic vomiting.gastritis, vomition and weight loss are common in captive cheetahs (acinonyx jubatus). gastric spiral bacteria (helicobacter spp.) and the very small, viviparous nematode ollulanus tricuspis, a stomach worm of cats, are believed to be important causes. three sibling cheetahs at wellington zoo, new zealand, developed chronic vomiting, diarrhoea and debility. their parents were both south african-born. response to antibacterial treatment was poor. endoscopic examinations revealed chronic lymphopla ...200011212940
ollulanus tricuspis in domestic cats - prevalence and methods of post-mortem diagnosis.ollulanus tricuspus is a parasite of the stomach of domestic cats and other animals, with a worldwide distribution. it can sometimes cause severe gastritis. fifty-five cat stomachs were examined for o.tricuspis using three techniques. o.tricuspis was found in seven stomachs (13%) from adult cats; the number of parasites recovered from individual cats ranged from 9 to 119 (mean 54). the prevalence was higher than that previously recorded in new zealand. repeated dilution and sedimentation of the ...198416031056
ollulanus tricuspis in a cat colony.the symptoms and pathology of a domestic cat infected with ollulanus are described. the subsequent investigation of the cat colony of which this cat was a member is detailed. it is concluded that ollulanus tricuspis is a significant pathogen in the colony and that the management and housing of the colony may simulate the conditions under which felidae in zoos have been shown to succumb to this parasite.198416031057
gastric adenocarcinoma and chronic gastritis in two related persian cats.two 12.5-year-old castrated male persian cats from the same household, whose dams were littermates, presented simultaneously with gastric adenocarcinoma associated with proliferative and fibrosing gastritis. intralesional adult ollulanus tricuspis nematodes and rare surface-associated spiral-shaped bacteria were identified in one cat. no etiologic agents were identified in tissues from the second cat; however, gastric mucosa was examined following anthelmintic treatment. clinical signs in each c ...200616672584
demonstration of ollulanus tricuspis in the stomach of domestic cats by biopsy.ollulanus tricuspis is a small nematode of the family ollulanidae, found in the stomach of domestic cats and other felids. of 131 gastric biopsy samples collected at endoscopic examination, four were shown to contain the parasite. vomiting was the main presenting sign in three cats and weight loss in the fourth. the stomachs were grossly normal on endoscopic examination. chronic gastritis was observed histologically in two cases, while the remaining cases were microscopically normal. the signifi ...200616701681
