Enteroparasitosis in schoolchildren of the Santa Anita district

Abstract

In the populous District of Santa Anita , located in the eastern side of Lima, which is considered urban- marginal social place ,was carried out a parasitologic study in children in five public schools by the laboratory of Parasitology of the Research Institute of the Faculty of Medicine of the San Martín de Porres University.
A single stool specimen of 956 students and 936 scotch cellophane slide was taken. Parasitology techniques were: Direct examination, Faust, Spontaneus sedimentation and Graham.
Results: 85% were positive and the comensal protozoa more frecuent E.nana 53.4%, E. coli 49.9% and the patogen G. lamblia 26.8 %.
The helmint more prevalent was H. nana 15%. The more afected group of age were from seven to eight years, they had Protozoa 45.7% and Helmints 0.4%. E. vermicularis from Graham 35.5% with sintoms 27% and without sintoms 8.5% and were more prevalent in the five and six year old age.
The prevalence for only Protozoa was 37%, Helmints 14% and mixed 34%.
A multiple parasitism was observed, even with seven parasits but the more frecuent was one parasite 16% in Protozoos and 13% in Helmints. In case of multiple parasitism three parasites is more common (2%).
It is necesary to incorpora te a sanitary education in the curriculum of public schools to prevent parasitism in children.
