Abstract: From each of a group of 217 adult males selected through enzyme-immunoassay or skin-test (Group A), six stool samples were examined by both the Lutz/Hoffman, Pons & Janer (Lutz/HPJ) and Kato/Katz methods. In addition, one oogram of the rectal mucosa was performed. By these methods, schistosomiasis was detected in 44.7%, 47.5% and 40.1% of the individuals respectively. To evaluate the methods in the assessment of cure, the last 40 patients from group A, treated with a single oral dose of oxamniquine at 15 mg/kg… Show more

“…This procedure is mainly indicated when the population group studied presents a low prevalence and a low intensity of infection and in the control of cure, situations in which the expected number of eggs in the feces is small. The sensitivity of the examination of only one fecal sample compared to the examination of four samples was of 84.9% and 100% when the number of eggs per gram of feces was greater than 50, 100 and 500, respectively, in an endemic area of low prevalence and intensity of infection (Rabello et al 1992).…”

“…Regarding the available techniques for the parasitological feces examination, in the most recent publications it remains the consonance that the Kato-Katz method (Katz et al 1972) offers the best conditions of effectiveness associated to the cost and operational conditions (Mott & Cline 1980, Sleigh et al 1982, Rabello et al 1992, WHO 1993.…”

“…For example, some authors prefer rectal biopsy for cure control (da Cunha et al 1987), but this method is difficult to perform in field condition. Therefore, most investigators defend the use of repeated stool examinations (Rabello et al 1992). Increasing the number of stool examinations will increase the probability of finding positive samples and consequently decrease the putative efficacy of the drug.…”
