geographic variation in helminth parasites from the digestive tract of tennessee raccoons, procyon lotor.the stomachs and intestinal tracts of 253 raccoons, procyon lotor, were examined for helminth parasites. sixteen species of helminths were found including eight trematodes, two cestodes, five nematodes, and one acanthocephalan. fourteen of these helminths are new geographic records for the state of tennessee. multivariate statistical techniques were used to analyze two-state and multistate character sets. matrices of correlation among characters were computed and the first three principal compon ...19807365628
macracanthorhynchus ingens infection in a dog.a 4-month-old sexually intact female siberian husky was examined because of diarrhea and 4 flesh-colored annulated helminths that were recovered from the dog's feces. infection with macracanthorhynchus ingens was diagnosed on the basis of morphologic features of the adult parasites and ova. spindle-shaped eggs (mean length, 91 microm; mean width; 54 microm) were obtained from the body cavity of a gravid female specimen. the dog was treated empirically with epsiprantel (5.5 mg/kg [2.5 mg/lb] of b ...200111469574
parasitic helminths of free-ranging mink (neovison vison mink) from southern florida.five free-ranging mink, neovison vison mink, from in or near the fakahatchee strand preserve state park, collier county, florida (26 degrees 00'n, 81 degrees 25'w), were examined for parasitic helminths. nine species of helminths were identified (2 trematodes, 5 nematodes, and 2 acanthocephalans). the most prevalent parasites were molineus patens (4 of 5 mink), mean intensity 173 (range, 12-342); strongyloides sp. (4 of 5), mean intensity 48 (range, 1-170); macracanthorhynchus ingens (immature) ...200717918381

macracanthorhynchus ingens infection in an 18-month-old child in florida: a case report and review of acanthocephaliasis in humans.a case of acanthocephaliasis in an 18-month-old child caused by macracanthorhynchus ingens is reported from florida. this represents only the third documented case of this species in a human host. an overview of human cases of acanthocephaliasis in the literature is presented, along with a review of the biology, clinical manifestations and pathology in the human host, morphology, and diagnosis.201627501844
helminths of sympatric striped, hog-nosed, and spotted skunks in west-central texas.twenty-eight hog-nosed skunks (conepatus leuconotus), 23 striped skunks (mephitis mephitis), and nine spotted skunks (spilogale gracilis) from an area of sympatry in west-central texas were examined for helminth parasites. shared helminth species among all three host species were one nematode (physaloptera maxillaris), two acanthocephalans (pachysentis canicola, macracanthorhynchus ingens), and one cestode (mathevotaenia mephitis). two nematodes (gongylonema sp. and filaria taxidaea) occurred in ...200617092881

survival of macracanthorhynchus ingens in swine and histopathology of infection in swine and raccoons.animal husbandry aimed at preventing macracanthorhynchus hirudinaceus infections in swine is not successful in preventing exposure to macracanthorhynchus ingens, and it is probable that pigs occasionally acquire acanthocephalans of that species. in some pigs, m. ingens survived 2 weeks and grew several millimeters. in such cases, destruction of villi, erosion of epithelium, leukocytic infiltration, and altered cytological structure at attachment sites accompanied the infection. penetration was l ...19863734995
helminths of the raccoon (procyon lotor) in western kentucky.seventy raccoons (procyon lotor) from western kentucky were examined for helminths from december 1985 through may 1986. twenty-three species of helminths were collected including 10 species of trematoda (brachylaima virginiana, euryhelmis squamula, eurytrema procyonis, fibricola cratera, gyrosoma singulare, maritreminoides nettae, mesostephanus appendiculatoides, metagonimoides oregonensis, paragonimus kellicotti, pharyngostomoides procyonis), 2 species of cestoda (atriotaenia procyonis, mesoces ...19873625429
epizootic and zoonotic helminths of the bobcat (lynx rufus) in illinois and a comparison of its helminth component communities across the american midwest.a total of 6257 helminths of 19 taxa were recovered from the digestive tract and lungs of 67 bobcats in illinois. infections caused by alaria mustelae, diphyllobothrium latum, and macracanthorhynchus ingens are reported for the first time in bobcats. from all the taxa recovered, only three species occurred in high prevalence and caused intense infections: taenia rileyi, alaria marcianae, and toxocara cati, with prevalence and mean intensity of 70% and 6; 42% and 193, and 25% and 14 individuals, ...201424521984
the guest playing host: colonization of the introduced mediterranean gecko, hemidactylus turcicus, by helminth parasites in southeastern louisiana.parasite surveys of exotic hosts offer the opportunity to examine parasite colonization on different scales (i.e., host individual, host population, host species, and new geographic locality). ten helminths (macracanthorhynchus ingens, mesocestoides lineatus, oochoristica javaensis, haematoloechus varioplexus, mesocoelium monas, telorchis corti, cosmocercoides variabilis, oswaldocruzia leidyi, skrjabinoptera sp., and a larval acuariid nematode) were recovered from the exotic mediterranean gecko ...200111780810
