| experimental infection of cats with the liver fluke platynosomum concinnum,. | the severity of platynosomum concinnum infection in cats experimentally infected with 125 flukes (small dose) and 1,000 flukes (large dose) was determined by monitoring clinical signs and hematologic, serum biochemical, and pathologic changes during the infection. all cats (8/8) with a small fluke burden and 3 of 8 cats with a large burden remained clinically asymptomatic, whereas 60% of the cats given large doses had mild signs of inappetence and lethargy. eosinophilia, peaking 4 to 5 months af ... | 1977 | 402094 |
| [buxtonella sulcata, an intestinal ciliate of apparently frequent occurrence in danish cattle (author's transl)]. | faeces samples from 762 apparently healthy heifers were examined for eggs of fasciola hepatica (sedimentation test). at the same time possible ciliate cysts were recorded. such cysts, usually circular, and varying in size from ab. 55 micrometer to ab. 95 micrometer (average ab. 71 micrometer) were found in 71.8 % of the samples. according to morphological descriptions in literature, the cysts observed are supposed mainly to represent the species buxtonella sulcata. their presence in faeces sampl ... | 1977 | 411113 |
| phenol oxidase activity: inductionin female schistosomes by in vitro incubation. | a biochemical methods has been developed for detecting phenol oxidase in female schistosoma mansoni. enzyme activity is observed only after incubation of the female schistosomes for an extended period of time in tissue culture media. male s. mansoni do not contain detectable levels of phenol oxidase activity. the properties of this enzyme are similar to those identified for a phenol oxidase from fasciola hepatica. l-dopa, dopamine, and tyrosine were found to be good substrates for this enzyme. v ... | 1978 | 417162 |
| laurell crossed immunoelectrophoresis and affinity chromatography for the purification of a parasite antigen. | laurell crossed immunoelectrophoresis (two-dimensional electroimmunodiffusion) was used to prepare minute amounts of purified parasite antigens complexed with their precipitating antibodies obtained from rabbits. these complexes, emuslified in freund's complete adjuvant, were then used to prime rabbits for selective production of precipitins to the complexed antigens when the animals were later boosted with whole parasite extract. the igg antibody from the monospecific antiserum recovered was th ... | 1978 | 418120 |

| [fasciola hepatica in denmark. a survey on 15 years diagnostic examination on bovine faeces samples (author's transl)]. | the results of routine diagnostic examinations of 10,540 bovine faeces samples for eggs of fasciola hepatica during the period 1963-1977 are evaluated. 0n an average, 10.4% of the samples were positive. the frequency of positive samples was highest among samples from cows (14.4%) lowest among samples from calves (1.5%). of samples from heifers 10.1% were found positive. calculated on a monthly basis, the percentage of positive samples showed a clear seasonal variation, reaching a peak in the per ... | 1979 | 424278 |
| perilobular fibrosis in chronic bovine fascioliasis. | the character, extent, and localization of perilobular fibrosis were studied in cattle experimentally infected with fasciola hepatica. such fibrosis is indirectly due to the liver flukes. the regionally localized fibrosis results from cholestasis due to transient occlusion of branches of the biliary tree. in periobular fibrosis it is possible to distinguish a florid, an intermediate, and an uncomplicated form. the florid phase is marked by proliferation of the biliary epithelium and is followed ... | 1979 | 432878 |
| attempts to immunise rats and mice against infection with fasciola hepatica using antigens prepared from taenia hydatigena. | attempts were made to immunise rats and mice against infection with f. hepatica by oral dosing with t. hydatigena eggs, or by vaccination with various t. hydatigena antigen preparations. these antigens included extracts from t. hydatigena cysticerci and cyst fluid, and antigens collected during short-term (48 h) and long-term (14 days) in vitro cultivation of larvae. immunity was assessed by the numbers of f. hepatica recovered from the challenge infection in rats, and the mortality rates of inf ... | 1979 | 433385 |
| the longevity of fasciola hepatica metacercariae encysted on herbage. | an experiment was described in which guinea pigs were used as tracer animals in an attempt to assess the longevity of fasciola hepatic metacercariae on pasture at werribee, victoria. the metacercariae had been encysted on both an irrigated and non-irrigated area at various times during 1976. it was determined that, under the conditions of the experiment, metacercariae can survive and remain viable for up to 10 weeks during the winter. it was also determined that longevity during the summer was g ... | 1979 | 444161 |
| the effect of prior infection with fasciola hepatica on the resistance of sheep to the same parasite. | the development of flukes that resulted from a challenge dose of 175 f. hepatica metacercariae was compared in 4 groups of sheep that were maintained under grazing conditions on fluke-free pasture. one group had been previously uninfected and all subgroups of each of the other 3 groups had been exposed to one of a range of previous doses of metacercariae. the preliminary infections of 2 of the 3 groups had been terminated respectively after 7 and 14 weeks. the third previously infected group had ... | 1979 | 444162 |

| fascioliasis: nitrogen balance studies and the disposition of excessive proline in rats. | nitrogen balance studies were conducted and the results compared between rats infected with fasciola hepatica and uninfected rats as follows: rats with 90 to 100 day infections were randomly selected and then matched by weight to uninfected controls. all rats were then fed a 6% protein diet for 3 days. nitrogen balance data indicated that infected rats excreted significantly higher urinary nitrogen than the healthy ones. as large quantities of proline were known to be released into the host in f ... | 1979 | 448471 |
