ABSTRACT

O objetivo deste estudo foi verificar a ocorrência de Strongyloides stercoralis e outros enteroparasitos em habitantes da área rural de Uberlândia, Minas Gerais, entre setembro de 1996 e maio de 1997, utilizando os métodos de Baermann-Moraes e de Lutz. Dos 180 indivíduos estudados, 92 (51,1por cento) estavam infectados. Doze indivíduos (6,7por cento) estavam infectados por S. stercoralis, sendo cinco em crianças com idade de entre zero e 12 anos e sete em indivíduos acima de 12 anos. Outros enteroparasitos diagnosticados foram Entamoeba coli (27,2por cento), Giardia lamblia (10,6por cento), Ancilostomatídeos (7,2por cento), Endolimax nana (3,9por cento), Ascaris lumbricoides (3,3por cento), Entamoeba hartmanni (3,3por cento), Enterobius vermicularis (2,2por cento), Hymenolepis nana (1,1por cento), Iodamoeba butschlii (1,1por cento), Entamoeba histolytica/dispar (0,6por cento) e Schistosoma mansoni (0,6por cento). Dos 92 casos positivos houve 71,0por cento de monoparasitismo, 25,0por cento biparasitismo e 4,0por cento poliparasitismo. Concluiu-se que a estrongiloidíase é hiperendêmica na área rural de Uberlândia. Destacamos a importância do uso de múltiplos métodos parasitológicos realizados em três diferentes amostras fecais de cada indivíduo que possibilitou a detecção de elevada taxa de enteroparasitas (51,1por cento) demonstrando um sério problema de Saúde Pública.

ABSTRACT

The aim of this study was to evaluate the enteroparasite and commensal occurrence in inhabitants living in the city of Abadia dos Dourados, Minas Gerais, Brazil. Three hundred and seventy six people were selected at random, 188 living in the rural area and 188 living in the urban area, from January through December of 1996. Using the Lutz method 177 (47.1 percent) individuals infected: 102 (57.6 percent) in the rural population and 75 (39.9 percent) in the urban population (P < 0.05). Of the total 177 enteroparasite and commensal occurrences diagnosed were: Entamoeba coli (18.3 percent), hookworm (17.8 percent), Endolimax nana (6.1 percent>), Giardia lamblia (5.8 percent), Ascaris lumbricoides (2.6 percent>), Entamoeba hartmanni (2.1 percent), Iodamoeba biltschlii (1.6 percent), Strongyloides ster cor alls (1.3 percent), Enterobius vermicularis (0.5 percent), and Trichostrongylus sp (0.5 percent). Geohelminths were predominant in the rural area, with an occurrence ofhookworm infections at 28.2 percent in these individuals and 7.4 percent in the urban people (OR: 14.33 CI: 6.230 to 32.970). The infection rate of enteroparasites was high in the population studied. In conclusion, it is necessary to implement regular parasitological exams and education about the forms and consequences of transmitting parasites, primarily among people living in the rural area.


El objetivo de este estudio fue evaluar la presencia de enteroparasitas y comensales en habitantes de la ciudad de Abadia dos Dourados, Minas Gerais, Brasil. 376 personas fueron seleccionadas aleatoriamente, 188 viviendo en el área rural y 188 viviendo en el área urbana, enero a diciembre de 1996. Usando el método de Lutz, 177 (47,1 por ciento) individuos estaban infectados, siendo 102 (57,6 por ciento) del área rural y 75 (39,9 por ciento) del área urbana (P < 0,05). Del total de 177 positivos, la ocurrencia de entoparasitas y comenzáis diagnosticadas fueron: Entamoeba coli (18,3 por ciento), hookworm (17,8 por ciento), Endolimax nana (6,1 por ciento), Giardia lamblia (5,8 por ciento), Ascaris lumbricoides (2,6 por ciento), Entamoeba hartmanni (2,1 por ciento), Iodamoeba butschlii (1,6" por ciento), Stron-gyloides stercolaris (1,3 por ciento), Enterobius vermicularis (0,5 por ciento), y Trichostrongylus sp (0,5 por ciento), Geohelmintos fueron predominantes en el ßrea rural, con 28,2 por ciento de infección para hookworm en esta populación y 7,4 por ciento en la populación urbana (OR: 14,33 CI: 6.230 para 32.970). La tasa de infección para enteroparasitas fue alta en los individuos estudiados, siendo necesario hacer exámenes parasitológicos regulares en estas personas y adoptar medidas profilácticas sobre las formas y consecuencias de transmisión de parásitas, principalmente entre personas que viven en el área rural.

ABSTRACT

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 percent) were infected with larvae of S. stercoralis. The IFAT detected 19 (16.3 percent) and the ELISA 17 (18.5 percent) 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.
