The aim of this study was to analyze the parasitological tests of a population at a public hospital in Maceió-AL. A descriptive study was made between January and July of 2015 analyzing the parasitological tests of a population at a public hospital in Maceió-AL. Variables such as gender, age, positive tests, protozoan species, helminths species and parasitic associations were analyzed. Out of 1.581 tests, 806 (51%) tested positive. Regarding gender, 535 (67%) were from women. Helminths were the most predominant infections (63.94%), compared to protozoans (36.06%).
The Helminths with the highest number of infections were:
Ascaris lumbricoides (93.23%), Trichuris trichiura (2.32%) and Enterobius vermicularis (1.26%). Among protozoans, Endolimax nana and Entamoeba coli corresponded to78.09% and 15.91% respectively. Although non pathogenic, it suggests fecal contamination. According to the degree of parasitism, 84.0% were monoparasitism. It can be concluded that the number of positive tests for enteroparasites was high, mainly in men. The species A. lumbricoides was the main helminth detected, while E. nana was the main protozoan found in the tests. The age group between 24 and 59 years old was the one that had the highest amount of positive tests. The results observed strengthen the need for the implementation of prevention measures for intestinal parasitic infections.
Os estudos da ocorrência de parasitoses em laboratório são de grande relevância, pois os mesmos podem proporcionar informações necessárias no diagnóstico da infecção e avaliar o índice de infecção parasitária, principalmente dos países em desenvolvimento, constituindo um problema de saúde pública. Foram coletados dados de exames de fezes realizados no período de janeiro a julho de 2015 nos registros de exames coproparasitológicos de fezes, de um hospital universitário de Maceió-AL. Foram analisados 1.581 exames, realizados pelo método de Hoffmann, Pons e Janer. Foi possível verificar que 51% apresentaram positividade para um ou mais enteroparasitos, sendo 66% para o sexo feminino e 34% no sexo masculino. Predominaram-se as infecções causadas por helmintos, com 55%, seguido das infecções causadas por protozoários 45%.
