Prevalence of Amoebiasis by Entamoeba Histolytica/E. Dispar in Three Regions of Peru

摘要

This study was to determine the prevalence and distribution of amoebiasis caused by E. histolytica I E. dispar in the main three Peruvian regions. Parasitological and serological studies were performed in a 2605 persons population using direct, concentration, trichrome staining and ELISA with amoebiasis kit in a latex solution. Results for 1748 stool samples were as follows: 153 for E. histolytica (8,7%), 649 for B. hominis (37,1%), and 373 for G. lamblia (21,3%). Serological examinations for antibody detection in latex particles were performed in 857 persons, and 337 (39,3%) revealed the antibodies anti-E. histolytica. In the northern region, parasitological examination showing E. histolytica in 14,5%, the positive serological examination 41.1%; in the center the parasitological examination 6.4%, the serological examination was positive in 36,6%; and in the southern, parasitological examination was positive in 6,0% and serological examination was positive in 40,6%. These results allow us to point out that the prevalence of E. histolytica I E. dispar using microscopy light is similar to that reported by other authors and serological tests may be able to show the endemicity of these infections. A good knowledge of amoebiasis epidemiology will contribute with control strategies that will bring benefit for the general population.
