| isoenzymatic pattern and structure of glutamate dehydrogenase from ascaris suum. | the isoenzymatic pattern of glutamate dehydrogenase (gdh) has been described for ascaris suum a parasite of sus scrofa domestica. only one band of activity has been revealed, suggesting a monomorphic condition for this enzyme. also, the structure of gdh has been assayed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (sds-page) and silver staining. only one subunit was present with a molecular weight of about 55,000. a hexameric structure for gdh of a. suum is suggested. | 1992 | 1293199 |
| nematode parasite infections of domestic pigs in a sub-tropical and high-rainfall area of india. | fourteen hundred and ninety-six domestic pigs, sus scrofa domestica l., from a sub-tropical and high-rainfall area of india were examined over a period of 18 months to ascertain their nematode parasite spectrum. the eleven species recovered, arranged in descending order of prevalence, are as follows: ascaris suum, oesophagostomum dentatum, bourgelatia diducta, stephanurus dentatus, globocephalus connorfilii, physocephalus sexalutus, ascarops dentata, a. strongylina, pseudocruzia orientalis, seta ... | 1989 | 2787072 |
| protective immunity to ascaris suum: analysis of swine peripheral blood cell subsets using monoclonal antibodies and flow cytometry. | outbred domestic swine or sla inbred miniature swine were exposed to ascaris suum either naturally on contaminated lots or by inoculation with uv-irradiated attenuated eggs. both inbred and outbred swine developed virtually complete protection to a challenge of 10 000 eggs after natural exposure, but inbred swine were less resistant than outbred swine after uv-egg exposure. flow cytometric analysis of peripheral blood mononuclear cells from these animals, performed to determine changes in cell s ... | 1986 | 2939618 |
| cloning, structural analysis, and expression of the pig ige epsilon chain. | as a step in the evolutionary studies of immunoglobulin e (ige) and for the purpose of developing new reagents that will facilitate a more detailed analysis of ige-mediated inflammatory reactions in a large animal model, we here present the cloning of the epsilon chain of ige in the domestic pig (sus scrufa). a partial cdna clone for the epsilon chain of pig ige was isolated by polymerase chain reaction (pcr) amplification using degenerate primers directed against conserved regions in the second ... | 1997 | 9321425 |
| growth and structural features of the adult stage of ascaris suum (nematoda, ascaridoidea) from experimentally infected domestic pigs. | for studying the morphogenesis of the adult stage of ascaris suum, worms were obtained from experimentally infected domestic pigs. structural and morphometric features of a. suum are analyzed by light and scanning electron microscopy. it was shown that the increase in length of the worm from days 35 to 56 is based on a region-specific lengthening of individual transverse annuli in the cuticle. an increased worm size also results in an increased diameter of different cuticular sense organs. it is ... | 1998 | 9576498 |
| health status of a recently discovered population of feral swine in kansas. | twenty feral hogs (sus scrofa) from a newly discovered population on fort riley army base (kansas, usa) were shot and examined from november 1993 through february 1994 to assess the health of the population. the hogs were generally healthy, although serologic evidence indicated that some individuals had been exposed to parvovirus, enterovirus, and swine influenza. we found no indications of brucellosis, pseudorabies, or porcine respiratory and reproductive syndrome. lung worms (metastrongylus sp ... | 1999 | 10479106 |
| differentiation of cuticular structures during the growth of the third-stage larva of ascaris suum (nematoda, ascaridoidea) after emerging from the egg. | in order to monitor the early phases of the development of ascaris suum from domestic pigs, third-stage larvae, retrieved from the liver and the lungs, were studied by analyzing worm growth and length increase of individual transverse annuli in the cuticle. material for study using light and scanning electron microscopy was obtained from experimental infections. the results show that the third-stage larva (not the second-stage) after emergence from the egg grows continuously, without an ecdysis ... | 2000 | 10864234 |
| a slaughter slab survey for extra-intestinal porcine helminth infections in northern tanzania. | a survey on extra-intestinal porcine helminths was conducted at three slaughter slabs that receive pigs from mbulu, a district endemic for porcine cysticercosis in northern tanzania. seventy carcases of pigs between 1 and 2 years old were examined between december 1997 and march 1998. the examination involved ante-mortem lingual examination for taenia solium cysticercosis followed by post-mortem inspection. in addition, a laboratory procedure was performed to determine whether any of these domes ... | 2004 | 15241967 |
| population structure in ascaris suum (nematoda) among domestic swine in denmark as measured by whole genome dna fingerprinting. | we here analyze the population structure in the pig roundworm, ascaris suum, among domestic pigs in denmark using a whole-genome dna fingerprinting technique, "amplified fragment length polymorphism" (aflp) analysis. with these data, we can extract absolute gene frequency variance components and g-statistics for 135 independent nucleotide polymorphisms. the average proportion of total variance partitioned between jutland and zealand is less than 3% of the total variance, implying no restriction ... | 2005 | 16970605 |
| the house fly (musca domestica) as a potential vector of metazoan parasites caught in a pig-pen in germany. | in the present study a total of 224 specimens of the synanthropic house fly (musca domestica) were caught in a pig-pen of an organic farmer in dormagen (germany). the flies were examined for their potential as a carrier of metazoan parasites. on the exoskeletons and in the intestines of the flies the eggs and/or larvae of four endoparasite nematode species of domestic pigs (ascaris suum, strongyloides ransomi, metastrongylus sp., undetermined strongylida) were isolated. also one ectoparasite spe ... | 2009 | 19081196 |
| incidence of ascaris suum-specific antibodies in austrian patients with suspected larva migrans visceralis (vlm) syndrome. | the pig roundworm, ascaris suum, is commonly found in domestic pigs all over the world. the transmission to humans takes place by ingestion of infective a. suum eggs present in soil because pig manure is widely used as fertilizer. the possible role of a. suum in the human visceral larva migrans (vlm) syndrome has been discussed controversially during past decades, even though various case reports, particularly from japan document pulmonal, hepatic and even cerebral symptoms caused by migrating a ... | 2016 | 26637313 |
| anthelmintic efficacy of ivermectin and abamectin, administered orally for seven consecutive days (100 µg/kg/day), against nematodes in naturally infected pigs. | the present study aimed to evaluate ivermectin and abamectin, both administered orally in naturally infected domestic swine, as well as analysing if the epg (eggs per gram of faeces) values were equivalent with the ivermectin and abamectin efficacy obtained by parasitological necropsies. the animals were randomly selected based on the average of three consecutive epg counts of strongylida, ascaris suum and trichuris for experiment i, and of strongylida and trichuris for experiment ii. after the ... | 2014 | 25278142 |
| experimental infection of collared peccary ( dicotyles tajacu angulatus ) with swine kidney worm ( stephanurus dentatus ). | two captive-born juvenile collared peccaries ( dicotyles tajacu angulatus ) were given 3000 infective larvae of stephanurus dentatus per os. one peccary harbored viable s. dentatus sub-adults in the liver 50 days post-infection. the other peccary had no larvae but did have diffuse fibrotic hepatic lesions and bile duct hyperplasia 213 days post-infection; however, the lesions may have been partially due to a concurrent ascaris suum infection. a domestic pig ( sus scrofa domesticus ) infected as ... | 1977 | 24228971 |
