internal parasites of horses on mixed grassveld and bushveld in transvaal, republic of south africa. | between 1980 and 1982, the gastrointestinal tracts of 17 horses which had been grazing on mixed grassveld at potchefstroom and bushveld at onderstepoort in the province of transvaal, republic of south africa, were examined at necropsy and processed for parasite recovery. the large strongyles and their prevalences were as follows: strongylus vulgaris and associated lesions (88-94%), strongylus edentatus (24%), strongylus equinus (30%), triodontophorus nipponicus (35%) and craterostomum acuticauda ... | 1989 | 2588465 |
field study on the efficacy of an oral 2% ivermectin formulation in horses. | twenty horses naturally infected with nematodes were included in a blind, controlled field study on efficacy and safety of an oral 2% ivermectin formulation at a dose of 0.2 mg.kg(-1). horses were divided into treated and non-treated (control) groups with ten animals each based on preliminary counts of eggs per gram of feces (epg). stool samples were collected after treatment for identification of nematode species. clinical evaluations and epg counts were performed on days 0, +5, +14 and +19. ni ... | 2011 | 21722495 |
gastrointestinal parasitic worms in equines in the paraíba valley, state of são paulo, brazil. | over a period of 12 years, from 1988 to 2000, a total of 20 individual equines (16 horses and 4 mules) were selected at random, from 10 municipalities in the paraíba valley, in the state of são paulo, brazil, and then subjected to necropsy for collection of gastrointestinal worms. individual samples of 10% of the intestinal contents were also taken for counting and identifying the species present, and to establish the prevalence of worms in equine species in the paraíba valley. in the sample con ... | 2006 | 16687215 |
re-evaluation of ivermectin efficacy against equine gastrointestinal parasites. | two trials were conducted to confirm the efficacy of ivermectin paste against endoparasites of horses. in these trials, 20 ponies were treated with ivermectin oral paste at 200 mcg x kg body weight once on day 0, and 20 ponies served as unmedicated controls. the animals carried naturally acquired parasite infections as confirmed by pretrial fecal examination. the animals were necropsied for worm recovery on days 14, 15 or 16. parasites recovered were identified to species. horses treated with iv ... | 2001 | 11423189 |
efficacy of a 2 per cent moxidectin gel against gastrointestinal parasites of ponies. | the efficacy of moxidectin was evaluated in young ponies naturally infected with gastrointestinal parasites. eight animals were treated orally with moxidectin at 0.4 mg/kg bodyweight and eight received only the vehicle. they were all necropsied two weeks later. faecal samples were examined daily for egg counts and larval cultures. parasites were recovered from total faecal samples collected daily and from the gastrointestinal tracts at necropsy. moxidectin reduced the strongyle egg counts by > 9 ... | 1998 | 9854319 |
study on the gastrointestinal parasite fauna of ponies in northern germany. | quantitative faecal and post-mortem examinations of 16 ponies, 1 to 2 1/2 years of age, originating from 3 farms in northern germany were performed in february 1995 to determine the prevalence and intensity of gastrointestinal parasites in these animals. a total of 33 species of metazoan parasites was recovered: three tapeworm species (anoplocephala perfoliata, a. magna, paranoplocephala mamillana), strongylus vulgaris, s. edentatus, small strongyles (including four triodontophorus spp., cratero ... | 1996 | 9060170 |
the prevalence and epidemiology of gastrointestinal parasites of horses in victoria, australia. | a quantitative post mortem study of 150 horses from victoria was conducted to determine the prevalence and epidemiology of gastrointestinal parasites. a total of 42 species of metazoan parasite was found. the following species of non-cyathostome parasite were found (% prevalence): trichostrongylus axei (51%); habronema muscae (13%); h. majus (2%); draschia megastoma (5%); gastreophilus intestinalis (81%); g. nasalis (29%); parascaris equorum (5%); anoplocephala perfoliata (29%); fasciola hepatic ... | 1995 | 7657457 |
studies on the parasites of zebras. 1. nematodes of the burchell's zebra in the kruger national park. | nineteen species of gastro-intestinal nematodes were recovered from 10 burchell's zebra. these include: cyathostomum alveatum, c. montgomeryi and c. tetracanthum; cylicocyclus auriculatus, c. gyalocephaloides, c. insigne and c. triramosus; cylicodontophorus schürmanni and cylicodontophorus n.sp., cylicostephanus bidentatus, c. calicatus and c. minutus; poteriostomum ratzii, craterostomum acuticaudatum, triodontophorus minor, habronema majus, h. muscae, h. zebrae, and draschia megastoma, as well ... | 1983 | 6634083 |
a survey in louisiana of intestinal helminths of ponies with little exposure to anthelmintics. | ponies reared with minimal or no exposure to anthelmintics were surveyed for intestinal helminths in order to estimate prevalence and intensity of parasite populations unaltered by frequent exposure to anthelmintics. thirty-seven mixed breed ponies of varying ages were examined. thirty-four species of nematodes and 2 species of cestodes were found. twenty-four of the nematode species (including 1 new species) were in the subfamily cyathostominae (small strongyles). eighty-seven percent of the to ... | 1986 | 3819969 |
nematode parasites from burchell's zebras in south africa. | twenty-five burchell's zebras (equus burchelli antiquorum) which were culled at monthly intervals in the kruger national park were examined for helminths. twenty-nine species of nematodes belonging to the families atractidae, habronematidae, onchocercidae, oxyuridae, strongylidae, strongyloididae and trichostrongylidae were recovered. the cyathostomes (small strongyles) most abundant were cyathostomum tetracanthum, cylicostephanus calicatus, cylindropharynx sp. (? c. intermedia theiler, 1923) an ... | 1987 | 3625897 |
