Detection of Cryptosporidium sp. in non diarrheal faeces from children, in a day care center in the city of São Paulo, Brazil

Abstract

The protozoan Cryptosporidium sp. has been frequently detected in faeces from children with persistent diarrhoea. This work achieved to investigate an outbreak of cryptosporidiosis, in a day care center, attending children of high socio-economic level, between 0 and six years old. The outbreak was detected through the network of public health, when stool samples, not diarrhoeic, were examined at the Parasitology Service of the Adolfo Lutz Institute. Among the 64 examined children, 13 (20.3%) showed oocysts of Cryptosporidium sp. in the faeces examined by Kinyoun technique: seven children one year old, three, two years old and three, three years old. Among the 23 examined adults, only a 22 years old woman, possibly having an immunocomprometiment, was positive. Clinical and epidemiological aspects were investigated by questionnaires, highlighting the occurrence of the outbreak in a very dry period.

Genotypic Characterization of Cryptosporidium hominis from Water Samples in São Paulo, Brazil

“…Therefore, standardization of efficient, reproducible, and simple techniques are still needed to ensure that these methods will not remain restricted to research centers. 8 In São Paulo State, Brazil, studies have described the presence of Cryptosporidium oocysts in water sources, 9-12 sewage, 13,14 bottled mineral water, 15 marine bivalve mollusks, 16 and day care centers, 17,18 but no waterborne infections have been reported.…”
