| Sumario: | The Schistosomiasis is endemic in 76 countries and territories. In mid 2003, it was estimated that 779 million people were within the population at risk for schistosomiasis, 207 million people were infected. The laboratory diagnosis of schistosomiasis can be accomplished through methods for parasites, ranging from classics (Kato-Katz), a few that are still undergoing validation. This study was conducted to evaluate two coproscopic new methods for diagnosis of Schistosomiasis in residents of an area of low endemicity in Maranguape-Ceará, using the Kato-Katz as a reference and serology (ELISA) for screening of patients. We developed the following steps: knowing the area and dissemination of the project with residents in the locality; Home visit to signing the consent form and interview to collect epidemiologic data, blood collection for performing the serological method, distribution of the bottles for feces, only for participants who were reactive in serological testing, collection of stool samples and carrying out the methods coproscopic and finally, delivery of results of examinations and treatment of positive individuals. Comparing the results obtained by the Kato-Katz method and salt gradient was seen that the 13 positive (23.2%) found by both, 10 (76.9%) were diagnosed only by the saline gradient. Even when we compared the method of Kato-Katz and Helmintex of the 32 samples analyzed, 16 were positive (50%) for both, however, 12 (75%) of these individuals were diagnosed only by Helmintex. And when comparing the method the saline gradient with Helmintex in 32 individuals who completed these, 17 (53%) were positive by both techniques, 11 (64.7%) positive only in Helmintex. Thus, the methods of the Saline Gradiente and Helmintex were more effective in the diagnosis of schistosomiasis in locus study, when compared to the Kato-Katz, but on the way of implementing the techniques, they may not be suitable for large surveys epidemiological, but for specific studies in areas where the driver fails to achieve the goals. |
