distribution of necator americanus and ancylostoma duodenale in the first country-wide survey of hookworm infection in liberia, diagnosis by test-tube filter-paper cultivation revealed a prevalence of more than 90%. this sensitive technique also permitted differential species determination. necator americanus was found to occur in all regions and in a high proportion of the persons examined. ancylostoma duodenale was mainly confined to a narrow coastal belt, and usually parasitized individuals harbouring n. americanus as well. the average number of eggs p ...19724539819

pyrantel embonate in treatment of hookworm infestation.the efficacy of pyrantel embonate (1,4,5,6-tetrahydro-1-methyl-2-(trans-2-(2-thienyl)-vinyl)-pyrimidine embonic acid salt; combantrin) was evaluated in 60 cases of hookworm infestation. they were divided into six groups of 10 cases. pyrantel embonate was administered orally, in dosage schedules (randomized) of 100, 75, 50, 20, 15, and 10 mg/kg of body weight. the stool examination for hookworm ova and coproculture were positive in each case. the predominant species was ancylostoma duodenale (in ...19715124439

iron loss and reabsorption in ancylostoma duodenale infection and bilharzial colonic polyposis.individuals infected with ancylostoma duodenale may lose up to 6 mg of iron daily and those infected with bilharzial colonic polyposis may lose an average of 3 mg daily; patients suffering with both infections may lose up to 9 mg of iron daily. 1 study has shown that some iron loss to the upper gastrointestinal tract was reabsorbed. a study was undertaken to ascertain whether any iron lost in the lower gastrointestinal tract is reabsorbed and to measure the amount of iron reabsorbed in patient ...19705495636
