Prevalence of Intestinal Parasitic Infection in Three Rural Communities in Mexico: Critical Overview | Chapter 4 | Recent Progress in Microbiology and Biotechnology Vol.1

 Introduction: In Mexico there are communities with significant lags compared to the rest of the

country because they have a high level of marginalization and low human development and of which it
is not known if the frequency and type of parasites that prevail in these areas. The purpose of this
work was to know the prevalence of intestinal parasites and the risk factors in Bahuinocachi
(Bocoyna, Chihuahua), Llano de la Parota and Agua Tordillo (Acatepec, Guerrero).
Methodology: The study was cross-sectional of 205 participants. Blood and feces samples were
collected. Data on demographics and predisposing factors of intestinal parasitic infection were
collected using a questionnaire. The feces were analyzed microscopically after a concentration
procedure and the sera were used to search for antibodies against A. lumbricoides, T. canis and
E. histolytica by ELISA.
Results: The overall prevalence of parasitosis was 70.1%. Agua Tordillo presented the highest
prevalence of antibodies against A. lumbricoides.
Conclusions: The three communities studied presented intestinal parasite infection. In Bahuinocachi,
protozoas predominate and in Llano la Parota and Agua Tordillo there was co-infection of helminths
and protozoa. The study has highlighted the importance of the intestinal parasitic in the communities
studied. It is necessary to get better the basic sanitary and environmental conditions as well as the
need implement for programs in health education, because it was found that Ascariasis is a health
problem and also there is coinfection with protozoa.
