MACHADO, ELEUZA R et al. Immunoparasitological diagnosis of Strongyloides stercoralis in garbage collectors in Uberlândia, MQ Brazil. Parasitol. latinoam. [online]. 2007, vol.62, n.3-4, pp.180-182. ISSN 0717-7712. http://dx.doi.org/10.4067/S0717-77122007000200013.
The objective of this study was to determine the presence of Strongyloides stercoralis in urban garbage collectors through the use of immunological and parasitological methods. A total of 92 individuals were evaluated from August, 1997, to June, 1998. For the parasitological diagnosis Baermann and Lutz' methods were applied. The immunological diagnosis involved the indirect fluorescence antibody test (IFAT) and the enzyme-linked immunosorbent assay (ELISA) to detect specific IgG antibodies. Of the 92 workers examined, six (6.5%) were infected with larvae of S. stercoralis. The IFAT detected 19 (16.3%) and the ELISA 17 (18.5%) positive serum samples. The differences between the results of parasitological and immunological methods were statistically significant (p<0.05). These results demonstrate that there is a need to improve the health conditions of this category of city employees.
