Showing papers in "Veterinary Parasitology in 1995"

TL;DR: This second edition of the W.A.V.P. anthelmintic guidelines for ruminants includes updated guidance on standard parasitological procedures, dose titration, dose confirmation and clinical trials, and provides guidelines for evaluating products for efficacy against anthel Mintic resistant parasites, persistence of activity and prophylactic activity.

TL;DR: It is concluded that much effort has been expended by pharmaceutical, government, and academic scientists searching for broad-spectrum second generation avermectin and milbemycin products, but none has exceeded the original avermECTin in any fundamental way.

TL;DR: A general review is given of the tick-borne hemoparasitic diseases of greatest economic importance in ruminants, babesiosis, anaplasmosis, theileriosis and cowdriosis, each caused by one or more species of hemoprasites.

TL;DR: An overview is given of the currently available methods to diagnose babesiosis in livestock and the immunofluorescence antibody test is the most widely used, while the enzyme-linked immunosorbent assay (ELISA) is the test system which holds the greatest promise for the future.

TL;DR: Seroepidemiological studies showed that enzootic instability exist in herds in several areas of the region, but clinical cases occurred less frequently than expected and biotechnological methods may help in obtaining information on Babesia-Boophilus-Bos relationship and on the transmission of A. marginale.

TL;DR: It was concluded that supplementary feeding with FM substantially reduced the production losses attributable to infection with T. colubriformis and was associated with enhanced expulsion of the parasite burden.

TL;DR: The digestive tracts of 50 working horses from private farms in Poland were examined and thirteen cyathostome species showed a site preference in the ventral colon, five in the dorsal colon and three in the caecum.

TL;DR: Definition of these epitopes, in combination with improved understanding of immune mechanisms, provides the basis for development of effective recombinant vaccines against anaplasmosis and babesiosis.

TL;DR: It is shown that, under field conditions in grazing cattle, the vaccine is able to control B. microplus populations and it was shown to induce a protective response in vaccinated animals under controlled conditions.

TL;DR: The detection of current infection of individual dogs with E. granulosus by coproantigen ELISA has the potential to replace arecoline purgation, while specific serum antibody detection should be useful in assessing Echinococcus exposure in dog populations.

TL;DR: It is suggested that asymptomatic adults may play an important role in the epidemiology of cryptosporidiosis in calves, and Sucrose flotation proved a more sensitive technique, detecting oocysts in 92% of the samples tested, and highlighting the insensitivity of direct smears for detecting oocytes.

TL;DR: An epidemiological study of intestinal helminths in 843 foxes from southern England revealed the presence of 13 parasite species, including Trichuris vulpis, Brachylaima recurva, Macracanthorhynchus catulinus and ProsthorhynChus transversus are new host records for the UK.

TL;DR: This paper reports an outbreak of trypanosomosis due to Trypanosoma evansi in horses of the Pantanal Mato-grossense region of Brazil, where forty-eight horses died and abortion in one mare was recorded.

TL;DR: A strong correlation between the anti-Leishmania antibody levels obtained by ELISA and those obtained using IFA was observed, and it seems to be a suitable assay for large scale epidemiological studies.

TL;DR: Hookworms and whipworms in dogs occurred together more than would be expected by chance in 4 out of the 6 years for which data were available.

TL;DR: It was shown that daily feeding with the microfungus Duddingtonia flagrans during the first 2 months of the season led to a lowered herbage infectivity and a reduced acquisition of Ostertagia sp.

TL;DR: The prevalence of oocysts of Eimeria species in calves, yearlings and cows was determined on 38 Dutch dairy farms and Linear regression analysis showed that there is significant reduction in the OPG levels in calves infected with EIMeria, aged between 7 and 38 weeks.

TL;DR: A variety of hemoparasites occurs in ruminants of South America, but there is consensus on the significant economic impact of babesiosis and anaplasmosis, which has led to the concepts of enzootic stability and instability.

TL;DR: All these animals, infested with fleas and admitted to the Clinic of Medicine of the Veterinary Faculty in Thessaloniki for routine procedures, were from different habitats and originated from various parts of northern Greece.

TL;DR: Of 3841 serum samples from sows received from the Tennessee State Diagnostic Laboratory in 1991-1992, 1130 were positive for Toxoplasma gondii antibody, and from the analysis of the questionnaire, sows associated with cats were 2.6 times more likely to be seropositive for T. Gondii than sows that were not associated with Cats.

TL;DR: It was concluded that supplementary feeding with protein meal substantially reduced production losses attributable to nematode infections in young grazing sheep, due to an enhanced resilience of the host, rather than any major changes in development of protective immunity.

TL;DR: It is concluded that rgp63 produced in Escherichia coli is a safe vaccine molecule which gives only partial protection following vaccination in the vervet monkey host, and the molecule requires further improvement for vaccine and/or immunodiagnosis application.

TL;DR: A homogeneous extract of a 28-kDa cysteine protease of Fasciola gigantica adult worms was used as the antigen for immunodiagnosis of fasciolosis in livestock using the Falcon assay screening test enzyme-linked immunosorbent assay technique.

TL;DR: The faecal egg counts of sheep and goats were apparently not influenced by the small seasonal climatic variations and a periparturient rise in strongyle egg counts was observed in both animal species.

TL;DR: Blood derived vaccines based on parasites derived from culture, from blood of infected animals, and from ticks engender a level of protection against natural challenge that justifies their use in field of vaccination.

TL;DR: This brief review focuses on several epidemiologically relevant aspects of anaplasmosis, including the role of male ticks as intrastadial, biological vectors of Anaplasma through interhost transfer and opportunities provided by a recently developed in vitro tick feeding system in quantitating studies of tick-hemoparasite-host interactions.

TL;DR: The gastrointestinal nematodes of both sheep and goats on this farm are resistant to ivermectin and fenbendazole, whereas levamisole is still effective in sheep, but not in goats.

TL;DR: Tick infestation of the horses estimated by using a semiquantitative key ranged from at least five ticks on every horse to more than 100 ticks on many horses throughout the year, suggesting that this tick is a significant vector of B. caballi.

TL;DR: A critical review of the literature on the association between sarcoptic mange and reduced production performance of swine suggests that the production effects of mange infestation of growing pigs are variable and evaluating dermatitis lesions at slaughter may be an objective means for assessing the severity of mane infestation.

TL;DR: Antibodies against a specific 88-kDa antigen of Fasciola gigantica were used for the detection of circulating antigen in the sera of cattle with experimental and natural infections of F. gigsica by a double antibody ELISA, and this immunoassay greatly enhanced the specificity of immunodiagnosis of fasciolosis in naturally infected cattle.
