Marcadores de riesgo para individuos con altas cargas de ascaris lumbricoides en una comunidad rural del Estado Cojedes, Venezuela / Risk markers for the high worm burden condition for ascaris lumbricoides in a rural community of Venezuela

RESUMO

A total of 337 individuals from a rural community of Venezuela (Mapurite, Estado Cojedes) was studied. Stoll faecal examination was carried out and the total number of A. lumbricoides was recovered after the treatment of the individuals sampled with pyrantel pamoate at a dose of 10 mg/kg body weight in children and 15 mg/kg in adults. A relationship between the high worm burden condition (individuals excreting more than 100000 epg of A. lumbricoides) and the age of the hosts was found. Resulting with the major values of relative risk index (Rr) the 5-9 years old class (Rr=3,2 t=3,4). This relationship was nort found between high worm burden condition (HWB) and the sex of the hosts. The following individuals have the highest possibilities to become HWB with the combinations A Hb elevado A Hb elevado F (Rr=3,46 t=2,31) and Hb elevado A Hb elevado S (Rr=3,11 t=2,78). It was estimated that the selective treatment of the total HWB detected (72) with and effective product, determined a reduction of 95,4 percent of the environmental contamination with de eggs and 72,3 percent ot the worm burden
