Bassam F. Alzain

Abstract


This study was conducted in Beit Lahia town in order to find
the rate of prevalence of Strongyloides stercoralis parasite. The study reveals
that the prevalence rate of Strongyloides stercoralis was extremely high
compared to the previous studies conducted in the same region.
Beit Lahia town is located in the north governorate of Gaza Strip. It is
bordered in the west by the Mediterranean Sea, in the north by Israeli
colonization, Jabalia camp from the south, and Beit Hanoun town from the
east. The population of the town is nearly 55.000 people.
In order to conduct the study, random cases were selected from eleven unique
agricultural regions in Beit Lahia town. The prevalence of Strongyloides
stercoralis and other intestinal parasites were assessed by the examination of
stool specimen from each of the random selected 1600 individuals aged
between 3-18 years, using direct fecal smear and formalin- ether
concentration techniques.
The overall infection rate was 74.6 %( 1195) and 13.4 %( 213) of the cases
had multiple infections. The infection rate of Strongyloides cases was5.6%
(90) and most of those infected children were passing adult worms.
Moreover, 45.8 %( 733) of the children living near the sewage water pools
were infected by Ascaris lumbricoids. Amongest the protozoa infection,
Entamoeba histolytica was observed most frequently 5.5 %( 88) and Giardia
lamblia was 3.5 %( 56), other less commonly found parasites were T.
Trichura and H. nana. The high rate of parasitic and multiple infections
reflect the low socioeconomic status of the studied community.
