| helminth parasitisms among intermingling insular populations of white-tailed deer, feral cattle, and feral swine. | helminth infections among free-ranging, intermingling populations of white-tailed deer (odocoileus virginianus), cattle (bos taurus), and swine (sus scrofa) on an island off the georgia coast were studied. of 39 species of helminths collected, 19 were found in deer, 17 in cattle, and 13 in swine. of 28 species of helminths recovered from ruminants, 8, viz, capillaria bovis, cooperia punctata, dictyocaulus viviparus, gongylonema pulchrum, g verrucosum, haemonchus contortus, moniezia benedeni, and ... | 1975 | 123523 |
| prevalence and epidemiology of trichostrongylids in wyoming cattle with consideration of the inhibited development of ostertagia ostertagi. | during 1988, monthly collections of abomasa and the cranial portion of the small intestine of 208 native wyoming cattle were examined for adult and larval helminth parasites. egg counts were performed on colonic faecal specimens. the animals ranged from 7 months to 8 years of age and were sampled at slaughter houses or diagnostic laboratories from five different counties in the state. most of the cattle had ranged for a long time on non-irrigated, high altitude grass plains from about 1250 to 25 ... | 1996 | 8893483 |
| transtegumental diffusion of benzimidazole anthelmintics into moniezia benedeni: correlation with their octanol-water partition coefficients. | the experiments described here report on the correlation between the ex vivo diffusion of different benzimidazole (bzd) anthelmintics into the cestode parasite moniezia benedeni, and their octanol-water partition coefficients (p.c.). the characterisation of the drug diffusion process into target parasites is relevant to understand the mechanism of drug penetration and the pharmacological activity of anthelmintic drugs. specimens of the tapeworm m. benedeni, used as a helminth parasite model, wer ... | 2003 | 12810040 |
| quantitative chromatographic determination of several benzimidazole anthelmintic molecules in parasite material. | a specific, precise and accurate high-performance liquid chromatographic (hplc) analytical method has been developed for the quantitative determination of different benzimidazole (bzd) anthelmintics in parasite material (moniezia benedeni). mebendazole (mbz), oxibendazole (obz), flubendazole (flbz), albendazole (abz) ricobendazole (rbz), albendazole sulphone (abzso(2)), fenbendazole (fbz), oxfendazole (ofz) and fenbendazole sulphone (fbzso(2)) were measured simultaneously in m. benedeni, a sheep ... | 2003 | 14630366 |
| drug transport mechanisms in helminth parasites: passive diffusion of benzimidazole anthelmintics. | anthelmintic molecules must reach their receptors inside target parasites to exert the pharmacological effect. available data suggest that the main route of entry of antiparasitic drugs into helminth parasites would be through their external surface. however, it is unclear if trans-tegumental/cuticular penetration is the most important way of entry of benzimidazole (bzd) anthelmintics into their target parasites compared to oral ingestion. the relative involvement of active and passive transport ... | 2006 | 16430886 |
| genetic markers to distinguish moniezia expansa from m. benedeni (cestoda: anoplocephalidae) and evidence of the existence of cryptic species in australia. | multilocus enzyme electrophoresis (mee) was used to genetically compare moniezia spp. collected from sheep and cattle in southern australia. fifteen enzyme loci were established for the genetic characterisation of individual specimens of moniezia, which represents a significant increase in the number of loci that was previously available for these cestodes. another four enzyme loci were also identified as providing potential genetic markers. there were no differences in staining activity or band ... | 2007 | 17206509 |
| oxfendazole: anthelmintic activity in calves artificially infected with six species of nematodes and in calves naturally infested with tapeworms. | in a series of 5 trials, in which 115 artificially infected calves were used, larval anthelmintic tests were done to assess the activity of oxfendazole at 4, 5 mg/kg against all 3 parasitic stages of 6 species of namatodes. an efficacy of over 98% was demonstrated against the 4th stage larvae (l4), 5th and adult stages of haemonchus placei, ostertagia ostertagi, cooperia pectinata, bunostomum phlebotomum and oesophagostomum radiatum and the 3rd larval stage (l3) of h. placei and c. pectinata. ag ... | 1982 | 7175907 |
| anthelmintic efficacy of febantel against gastrointestinal helminths in calves. | three dosage levels of febantel were tested for anthelmintic activities in calves under field conditions. a total of 20 feeder calves affected with naturally occurring gastrointestinal parasites were used in the controlled test. the calves were allotted to 4 groups of 5 each on the basis of degree of parasitism, body weight, age, and sex. calves in groups ii through iv were treated with febantel paste formulation at dosage levels of 5, 7.5, and 10 mg/kg of body weight; calves in group i were use ... | 1982 | 7165174 |

| dynamics of infections with gastrointestinal parasites and dictyocaulus viviparus in dairy and beef cattle from costa rica. | a longitudinal survey was carried out to determine and describe the prevalence and intensity of gastrointestinal parasite infections and dictyocaulus viviparus in a dairy and a beef cattle farm of two different ecological zones in costa rica. the influence of anthelmintic treatment, age and meteorological factors (rainfall, minimum and maximum temperatures) on gastrointestinal nematodes and d. viviparus counts was determined. calves were subjected to monthly sampling of feces and blood between a ... | 2007 | 17656024 |
