RESUMEN
Este estudio ha tenido como finalidad actualizar los datos de parasitosis intestinal, estudiando 227 muestras de heces de niños de 1 a 12 años de comunidades rurales y urbanas. Se han empleado cuatro métodos: directo, de flotación o Willis, de concentración o MGL y Harada-Mori, éstos dos últimos diferentes a los rutinariamente empleados. En las zonas estudiadas se encontró que 166 niños (72, 8 por ciento) estaban parasitados, observándose protozoarios con mayor frecuencia que vermes.El método directo fue el más sensible, dando un porcentaje de positividad del 68.9 por ciento (n=157), le siguen el MGL 44 por ciento (n=100), Willis 36 por ciento (n=81) y cultivo 22.4 por ciento (n=51). Los paásitos más frecuentemente observados fueron: G. lamblia (23,7 por ciento), B. hominis (21,9 por ciento), A. lumbricoides (16,7 por ciento), N. Americanus (15,4 por ciento)

Parasitosis Intestinales , EucariontesRESUMEN
Feces from 64 Cebus apella monkeys were examined by the MGL method. The monkeys have been kept in captivity at IICS. Larvae resembling those of Strongyloides were found in 25 percent of the animals, eggs resembling thosse of Strongyloide in 39 percent of the animals and eggs resembling those of Cestode in 1.6 percent of them

Parasitosis Intestinales , Haplorrinos , ParaguayRESUMEN
The microfilaricidal effect if invermectin was studied on Cebus apella infected with dipetalonema gracile in Paraguay. Nine monkeys were treated with ivermectin at the dosage of 200 ug/kg boby wieght by single subcutaneous injection. The significant reduction in microfilarial count after treatament with ivermectin was recognized (p<0.01). The change of blood picture of 9 monkeys infected with Dipetalonema gracile following treatment of ivermectin was also studied. The total WBC count was found to be significantly increased at 1 day after treatment. Differential count study showed that neutrphlilis increased in most menkeys. On the other hand, the significant change in eosinophil and lynphocite count was not observed
