ABSTRACT
A cross-sectional study of cryptosporidiosis was carried out in Nicaragua. The prevalence of Cryptosporidium infection was determined in 272 (110 boys and 162 girls) schoolchildren, aged between 4 to 15 years from department of Rio San Juan. The total percentage obtained for Cryptosporidium (35.7%) was one of the highest reported so far. Cryptosporidium appeared in 94.8% of multiparasitism cases. No significant statistical differences were detected in the cryptosporidiosis prevalence between loose/watery (22.2%) and soft/formed (36.7%) stool samples. No significant age and sex differences were observed. This is the first report to identify Cryptosporidium in Nicaragua at species level, providing a preliminary molecular characterization of all positive samples, such as Cryptosporidium parvum (genotype 2). The high prevalence of C. parvum suggests that animals may be potential sources of infection for human cryptosporidiosis, although C. parvum infections may have originated from humans themselves. The human health problem caused by Cryptosporidium in this region may be related to the poor human hygiene/sanitation and contamination of the environment, food, or water supplies. Continuous exposure to the parasite could have been protective against development of symptoms in the children examined.
