| sus scrofa domestica endoparasitic resistance in the amazonas. | the domestic pig (sus scrofa domestica l.) has been wild breeding in the varzea amazonian estuary area. without dietary supplement or medical prevention, the pigs survive, bringing economic benefits to local peasants. endoparasitic diseases generate economic losses because of neonatal death and clinical disease. we assessed the nematoda (o. nematoda) and coccidia (o. eucoccidia) parasitic level and tolerance in 75 pigs (0-18 months) from 35 families using the following methods: (i) larvae cultur ... | 1996 | 8784532 |
| ultrastructure of spermiogenesis and the spermatozoon of macracanthorhynchus hirudinaceus (pallas, 1781) (acanthocephala: archiacanthocephala), a parasite of the wild boar sus scrofa. | the present paper describes the ultrastructure of spermiogenesis and the spermatozoon of macracanthorhynchus hirudinaceus, an acanthocephalan parasite of the wild boar sus scrofa. at the beginning of spermatogenesis, spermatocytes exhibit synaptonemal complexes and 2 centrioles. in the spermatid, only 1 centriole remains, generating a flagellum with a 9+2 pattern. another ultrastructural feature observed during the spermiogenesis of m. hirudinaceus is the condensation of the chromatin, forming a ... | 2005 | 16108538 |
| helminths of wild boar in spain. | forty-seven wild boars (sus scrofa) collected from two areas in the province of valencia (eastern spain) were examined for digestive and respiratory helminth parasites. helminth species and their prevalence were taenia hydatigena cysticercus (19%), ascarops strongylina (87%), physocephalus sexalatus (6%), ascaris suum (2%), metastrongylus spp. (85%), capillaria sp. (2%) and macracanthorhynchus hirudinaceus (21%). trichinella spp. were not found. physocephalus sexalatus, a. suum, capillaria sp. a ... | 2001 | 11763752 |
| study on a new egg count technique for macracanthorhynchus hirudinaceus and ascaris suum. | this paper deals with a new egg count technique for macracanthorhynchus hirudinaceus and ascaris suum. the making of the new counter and the operation are described. the eggs of m. hirudinaceus in the upper, the middle and the lower levels of the sediment from swine feces were counted by the new egg count technique and the numbers of the eggs in the sedimentary liquids diluted two, four, six, eight and ten times were nearly similar. this indicates that the eggs dispersed evenly in the sediment a ... | 1996 | 8750688 |
| flubendazole: dose range and efficacy studies against common internal parasites of swine. | the anthelmintic spectrum of activity and efficacy of flubendazole, using pigs naturally infected with helminth parasites, were determined in 4 experiments, using 157 pigs. flubendazole (1.5 mg/kg of body weight) mixed in feed or top-dressed on feed for 5 consecutive days was highly effective as an anthelmintic. this dosage level indicated 100% efficacy against mature ascaris suum, oesophagostomum dentatum, trichuris suis, and metastrongylus apri. there was 88% efficacy against strongyloides ran ... | 1983 | 6881670 |
| [light and electron microscopic studies of the histopathogenicity of macracanthorhynchus hirudinaceus (archiacanthocephala) in experimentally infected domestic swine]. | one and 12 weeks after infection the lesions in the small intestine of two domestic pigs caused by macracanthorhynchus hirudinaceus were studied by means of light and electron microscopy. worms of 7 d.p.i. were found to have penetrated with their presoma into the tunica propria and partly into the tunica muscularis where they had caused local mechanic destructions and heavy eosinophilic-like and hemorrhagic reactions. most eosinophilic-like granulocytes were attracted to the proboscis hooks, at ... | 1990 | 2336449 |
| coprological tests underestimate macracanthorhynchus hirudinaceus burden in wild boar. | the present study evaluated the limitations of the coprological sedimentation test to assess macracanthorhynchus hirudinaceus infestation in 59 wild boars (sus scrofa) from central spain. the coprological sedimentation test appeared to be a poor predictor of both prevalence of infestation and the real parasite burden due to the high number of false negative results (prevalence was reduced from 61 to 16 %). because of the potential increased risk of this zoonosis, it is suggested that alternative ... | 2016 | 26973238 |
| macracanthorhynchus hirudinaceus: the most common helminthic infection of wild boars in southwestern iran. | a pathological and epidemiological study on macracanthorhynchus hirudinaceus infection on 25 wild boars sus scrofa in southwestern iran was done. overall 24 helminthes (18 female and 6 male) were collected from the intestine of 13 infected wild boars. thus, the prevalence of acanthocephalans among the 25 examined boars was 52 %. pathological evaluation revealed damages caused by the acanthocephalans penetrated in the small intestine tissue. helminthes caused severe necrosis with ulcer and inflam ... | 2016 | 27876983 |
| helminth parasites of wild boars, sus scrofa, in bushehr province, southwestern iran. | wild boars, sus scrofa, of wide distribution considered as a potential source of zoonotic parasites. the current study aimed to assess the prevalence of helminth infections in wild boars in the persian gulf coastal area (bushehr province), southwestern iran. | 0 | 28127344 |
| helminth infections of wild boars ( sus scrofa) in the bursa province of turkey. | the present study aimed to investigate the status of helminth infections in wild boars in the bursa province of turkey. for this purpose, during 2007-2008, 27 wild boars were necropsied and examined for helminths. individual samples of tongue and diaphragm from 27 necropsied wild boars and an additional 22 tongue and diaphragm samples provided by hunters were examined by trichinoscopy and artificial digestion for trichinella spp. larvae. twenty animals (74%) were identified as being infected wit ... | 2010 | 21114894 |
| helminth parasites of the wild boar, sus scrofa, in luristan province, western iran and their public health significance. | seven helminth species were obtained from 12 wild boars (sus scrofa) during a survey from 2000 to 2001 in luristan province, western iran. these species include the cestode larvae cysticercus tenuicollis (25%), c. cellulosae (8.3%), the nematodes metastrongylus apri (41.6%), m. pudendotectus (16.6%), m. salmi (8.3%), trichuris suis (8.3%) and the acanthocephalan macracanthorhynchus hirudinaceus (41.6%). no trematodes were found. seven wild boars (58.3%) were identified as having at least one hel ... | 2003 | 12895286 |
