A comparative study of the relative efficacy of pyrantel pamoate, bephenium hydroxynaphthoate and tetrachlorethylene in the treatment of Necator americanus infection in Ceylon.
    Annals of tropical medicine and parasitology, 1975, Volume: 69, Issue:2

    The clearance of hookworm (Necator americanus) ova by a single dose of tetrachlorethylene (T.C.E.) was compared with that produced by single and multiple dose regimes of bephenium hydroxynaphthoate and pyrantel pamoate. Single doses of bephenium and pyrantel were inferior to T.C.E. Three daily doses of bephenium or pyrantel produced effects comparable with a single dose of T.C.E. Because of the low cost and lack of side effects, T.C.E. remains the drug of choice in the treatment of N. americanus in infections; the only disadvantage of T.C.E. is its unnoticed deterioration under tropical conditions.

Comparison of the structures of natural and re-established populations of Ascaris in humans in a rural community of Jiangxi, China.
    Parasitology, 2002, Volume: 124, Issue:Pt 6

    To compare the structures of natural and re-established populations of Ascaris in humans, universal (mass) chemotherapy was carried out at the beginning and the end of the study year using pyrantel pamoate. Worms expelled within 48 h of treatment were collected, their sex determined, and measurements made of length, width and weight. Length was used as the criterion for estimating the developmental stage of the worms. In comparison with the natural population, the reestablished population displayed similar sex ratio as well as distribution patterns among individuals and age groups of the host. However, the mean worm burden of the re-established population was significantly decreased, with a reduction of burdens in children aged 5-9 years. Also, the re-established population showed significant changes in population structure and worm measurements in that it comprised more immature and less fertile males, less fertile and more senile females, smaller and lighter males, larger (but not heavier) females than the natural population. The results suggested that the reestablished Ascaris population did not restore to its original status in relation to mean density, composition and fecundity. Therefore, universal treatment once a year should decrease the transmission of Ascaris in humans. Combined with previous results for the same study sites, the present findings also indicated that caution is warranted to avoid misleading conclusions when using prevalence and faecal egg counts as parameters for evaluating the success of control programmes.

Prevalence of benzimidazole-resistance in equine cyathostome populations in south east England.
    The Veterinary record, 1992, Apr-11, Volume: 130, Issue:15

    In order to study the prevalence of benzimidazole-resistance in equine cyathostomes, 30 stables in south east England were selected according to strict criteria but with minimum bias to provide three matched groups of 100 horses. One group was treated with fenbendazole, one with pyrantel embonate and the third was left untreated. The overall efficacies of fenbendazole and pyrantel embonate, as judged by the faecal egg-count reduction test, were 56.3 and 95.8 per cent, respectively. The numbers of horses at individual stables were too small to draw conclusions at each stable, but whereas efficacies greater than 85 per cent were recorded for pyrantel at 26 of 27 stables, the corresponding figure for fenbendazole was five of 27. Cyathostomes accounted for more than 90 per cent of the larvae cultured from faeces before and after treatment. Trichostrongylus axei was detected on 20 sites, but Strongylus species were present on only five. In the area of the survey, benzimidazole-resistance was very widespread in stables which used benzimidazole anthelmintics regularly and had more than nine horses per stable, but the benzimidazole-resistant cyathostome strains were adequately controlled with the non-benzimidazole anthelmintic pyrantel embonate.

Acquired immunity to Ancylostoma ceylanicum in hamsters.
    Parasite immunology, 1990, Volume: 12, Issue:3

    A laboratory model of acquired immunity to human hookworm is described. Significant resistance to challenge infection with Ancylostoma ceylanicum was elicited in mature DSN hamsters. The serum and mucosal antibody responses were investigated in both quantitative and qualitative terms and changes associated with immunity were identified. Marked differences in numbers of mast and goblet cells in the small intestine were also recorded and related to the immune status of the host.

Control of Toxocara canis in puppies: a comparison of screening techniques and evaluation of a dosing programme.
    Journal of veterinary pharmacology and therapeutics, 1987, Volume: 10, Issue:1

    Conventional chemoprophylaxis of canine toxocariasis is based upon the treatment of young puppies. It is proposed that physiological considerations and the complexity of the host-parasite relationship in the case of Toxocara canis demand that anthelmintic evaluation should properly be conducted in such animals rather than in adolescent or adult dogs. A screening model using the critical trial technique in early weaned pups gave variable results even with compounds known to be of high efficacy in older dogs. Circumstantial evidence suggested that this inconsistency may be related to the rate of passage of ingesta through such young animals. More satisfactory results were obtained by pairing unweaned naturally infected puppies by weight and sex and treating one of each pair with the test compound. Natural in utero and transmammary infection was found to give fairly consistent worm-burdens within each litter and a good indication of efficacy could therefore be estimated by comparing post mortem worm-counts. On this basis, the apparent efficacies of pyrantel pamoate (5 mg kg-1) and piperazine (100 mg kg-1) were found to be 83.5 and 82.5%, respectively. This method was extended to evaluate a prophylactic programme in which anthelmintic therapy was given to pups when aged 10, 20 and 30 days. Intestinal T. canis populations were reduced, at 35 days of age, by between 94.2% and 98.0%. This programme increased overall weight gains between 10 and 30 days of age by 18% (P less than 0.05) although there was great variation between litters. The biggest response was observed in male pups between 20 and 30 days old.
