The parasites found were: Ascaris lumbricoides
(15.7%), hookworm (11.9%), Strongyloides stercoralis (9.7%), Trichuris trichiura (4.7%), Enterobius vermicularis (2.1%), Taenia solium (0.8%), Schistosoma mansoni (0.6%), Entamoeba coli (9.7%), Iodamoeba butschlii (5%), Endolimax nana (2.1%), Giardia lamblia (1.8%) and Entamoeba histolytica (1.1%).
The distribution of Ascaris lumbricoides
in human hosts: a study of 1765 people in Bangladesh.
in infants: a population-based study in Rio de Janeiro, Brazil.
The most frequently detected parasites were Enterobius vermicularis (12.15% of all the examined), Ascaris lumbricoides
(0.83%) and Trichuris trichiura (0.12%).
The intestinal roundworm Ascaris lumbricoides
is a cylindrical nonsegmented worm measuring 15 to 40 cm long.
Abstract: The study presents an interactive descriptive tool (MONRATE) for calculating and predicting reinfection rates and time of Ascaris lumbricoides
following mass chemotherapy.
Entre los helmintos, Ancylostomideos (30,89%), Ascaris lumbricoides
(9,95%) e Hymenolepis nana (4,19%) ocuparon los primeros lugares.
The epidemiology of Ascaris lumbricoides
, Trichuris trichiura and hookworm in the children in the Ranomafana rainforest.
(Al), 3.2%; oxiuros (O), 5.1%; Giardia intestinalis (Gi), 23.5%; Blastocystis hominis (Bh), 20%; Hymenolepis nana (Hn), 1.3%.
Today, that number has multiplied more than eightfold and is paralleled by a growing number of outbreaks of parasites like Anisakis in raw and undercooked fish, Ascaris lumbricoides
on imported vegetables, Cryptosporidium on green onions and in chicken salad, Cyclospora on basil and raspberries and Giardia on raw sliced vegetables and fruit salad.
 In a rural community in China, 61% of the 215 people studied were infected with Ascaris lumbricoides
.  Of 1,261 individuals in Jiri, Nepal, 27% tested positive for roundworm.
The first report of an adult Ascaris lumbricoides
roundworm in the biliary ducts presenting clinically (and radiologically) in North America or the United Kingdom was published in 1977. Ascariasis is a helminthic infection of global distribution with more than 1.4 billion persons infected throughout the world.
