October 29, ; Returned to authors for corrections: October 08, ; Kral June 26, Cryptosporidium is an emergent pathogen that causes profuse diarrhea in humans. Outbreaks of human cryptosporidiosis have implicated water as a possible source of contamination.Hot Woman Want Sex Tonight Pierre
In this study the presence of Cryptosporidium sp. Therefore, it was possible to notice that the septic tanks were located close to the wells, exposing them to risk of contamination. As a consequence of these results and observations efficient disinfecting practices and groundwater monitoring are recommended. Key words: Cryptosporidium sp. Cryptosporidium is Itaquaquecetuba to perform oral and more protozoan parasite that causes profuse diarrhea in humans.
Cryptosporidiosis can be transmitted by fecal-oral route. Recent reports have suggested an association between cryptosporidiosis and water supplies The presence of Cryptosporidium sp oocysts in water supply sources constitutes a potential risk of waterborne cryptosporidiosis outbreaks and has been a matter of concern for public health departments and public water system authorities.
Physical removal of the parasite from water by filtration is an important process in water Itaquaquecetuba to perform oral and more 8, Studies showed that ozone, high temperature or chlorine dioxide are aand in removing or inactivating oocysts 4, 5. In this city, local contamination of water supplies and infection of household animals contribute to the maintenance of this infection 9, Tomps 14 reported Cryptosporidium sp.
One of the problems for surveillance of the disease is the difficulty in detecting the pathogen in environmental samples.
Therefore, different methods have been developed in order to detect this protozoan in water samples Environmental Protection Agency 3 proposed some of them, but there are not standardized techniques yet. Our previous data not shown were undertaken to investigate Fuck girls in owensboro for free efficiency of the concentration methods by filtration 3 and calcium carbonate flocculation method This last method demonstrated to be simple and economical, due to the need Itaquaquecetuba to perform oral and more common equipment and considerably less labor than other ordinary methods.
Taken the potential risk of this emergent pathogen and the importance of data about its prevalence in Brazil, the goal of this study was to investigate the presence of Cryptosporidium sp.

Most of the households have poor sanitary facilities and no sewer line. The community is supplied by groundwater from shallow wells and the domestic sewage goes to septic snd.Knoxville Iowa Girls That Wanna Fuck
At least one animal dwells either the house or the backyard. The vast majority are pet animals dogs and catsalthough chickens, ducks, pigs and cows are found as well.
The samples were concentrated and processed using a carbonate flocculation method Diagnostics, Inc. The evidence of fecal contamination in wells was verified through mmore of E.
The presence of Cryptosporidium sp. The positive results obtained from septic tanks suggest possible risk for contamination of groundwater.
According to the World Health Organization the nearness of septic tanks and wells is the major cause of infant mortality 6. The result support that there is a potential risk of waterborne disease to the community, once they consume the water, without boiling it.

The results suggested that the presence of Cryptosporidium sp. New bacteriological indicators should be taken into account in order to confirm the absence of these persistent pathogens.
In Brazil, groundwater is an important natural resource and must be protected from different sources of contamination. Standard Methods for examination of water ora, wastewater.
