Soil-transmitted helminth infections: ascariasis, trichuriasis
Our team has just evaluated the diagnosis performance of four immunological diagnosis kits for clonorchiasis in China. It is found that among the many different heterologous sera from cases with other parasitic diseases (including schistosomiasis, paragonimiasis, trichinellosis, ascariasis, hookworm disease, and trichuriasis
), those from paragonimiasis show most serious cross-reactivity to the antigens of C.
Under current regulations, 11 parasitic diseases are subject to mandatory reporting and registration: ascariasis, cryptosporidiosis, congenital toxoplasmosis, echinococcosis, giardiasis, hymenolepiasis, malaria, taeniasis, trichinellosis, trichuriasis
and visceral leishmaniasis (4).
The national prevalence of each infection was less than 5%, with a cumulative prevalence of 6.9% for all ascariasis, trichuriasis
, and hookworm infections .
Albonico et al., "Soil-transmitted helminth infections: ascariasis, trichuriasis
, and hookworm," The Lancet, vol.
This review was developed based on state-of-the art of beneficial bacteria research on helminths, mainly schistosomiasis, trichinellosis, toxocariasis, trichuriasis
, ascariasis, hookworms, and Strongyloides, and discussed accordingly.
The results were obtained from parasitological tests, with a prevalence of 25.15% for ascariasis, 7.36% for trichuriasis
, and 9.82% for hookworm (12).
Especificamente, en America Latina se estima que hay aproximadamente 100 millones de ninos padeciendo de trichuriasis
y 84 millones padeciendo de ascariasis (6).
 The WHO estimated that globally, there are 800-1000 million cases of ascariasis, 700-900 million of hookworm infection, 500 millions of trichuriasis
, 200 million of giardiasis, and 500 million of amoebiasis.
Estimates show that, in sub-Saharan Africa (SSA), about 198 million people are infected with hookworms , 192 million with schistosomiasis infection , 173 million with ascariasis infection , and 162 million with trichuriasis
It is the means of combating helminthic infections such as schistosomiasis, ascariasis, Lymphatic filariasis, trichuriasis
, onchocerciasis, and trachoma.
