Comparación entre el método de Ritchie y el método de Willis para la identificación de protozoos intestinales en escolares

The parasite is a serious public health problem that particularly affects infants, affecting nutritional and intellectual status, is one of the transmissible, frequent and difficult disease to control their spread, as there are 50 million parasitosis caused by protozoa worldwide, with 40,000 to 50,000 deaths annually (1). This research descriptive cross-sectional allowed to know which method is the most accurate for the diagnosis of protozoa in school, whose objective was to identify intestinal protozoa using the method of Ritchie and Willis in school and identify the presence of protozoa by sex and age, for which featured a sample of 57 schoolchildren. Upon completion of the analysis of the results it showed that 100% of schoolchildren are infected by protozoa using the method of Ritchie with a presence of 82% equivalent to 100 protozoa; And Willis with a presence of 29% equivalent to 100 protozoa. And Willis with a presence of 29% equivalent to 100 protozoa. Was identified as the most common method protozoon E. histolytica Ritchie was at a frequency of 42 to 51%, B. hominis with a frequency of 14 or 17%; E. coli with a frequency of 13 equivalent to 16%, and G. lamblia with a frequency of 13 equivalent to 16%. Meanwhile, with the only protozoan it was Willis E. histolytica 29 with a frequency equal to 100%. In terms of gender: children have a higher rate of infection with a parasitic frequency of 61 or 55%, compared to girls with a parasitic frequency of 50 equivalent to 45%; Applying age and in children 5-8 Ritchie was evident: E. histolytica by 51%, E. Coli by 14%, B. hominis 16%, G. lamblia around 18% of 100% and 9-12 years presented: E. histolytica by 53%, E. Coli by 18%, B. hominis 18%, G. lamblia around 12% of 100%. As for the method of Willis was the only identified protozoan: E. histolytica with a frequency of 18 children 5-8 years and of 100% in children 9-12 years with a frequency of 10 equal to 100%. Keywords: Protozoa, Ritchie and Methods Willis, School.
