Descrição
Resumo:Water-borne diseases caused by opportunistic protozoa re-emerged as an important public health problem in recentyears, despite technological advances in water treatment processes. In this context, agents such as Cryptosporidium andGiardia produce (oo)cysts resistant to conventional water treatment and can cause serious cases of morbidity in immunocompromisedindividuals. In Brazil, water control by specific and sensitive techniques aimed at detecting Cryptosporidiumand Giardia still is not widespread. The aim of this study was to do a critical analysis of the scientific evidence onthe contamination of public water supplies by Cryptosporidium and Giardia. We did a systematic review of the literatureproduced from 2001 to 2011 in PUBMED and LILACS databases. From the results, we find a cosmopolitan distribution ofthese parasites in different sources of treated water, representing a risk to public health and a challenge for environmentalmonitoring, considering the specificity and high cost of internationally recognized analytical techniques for identifyingthese pathogens in water
