Resumo
O complexo teníase-cisticercose é causado pelos cestódeos Taenia saginata e Taenia solium, que têm o homem como hospedeiro definitivo e obrigatório e os bovinos e os suínos, respectivamente, como hospedeiros intermediários. A presença da forma adulta destes cestódeos no intestino delgado causa pequenos danos ao homem, enquanto a presença das formas larvárias nos tecidos e órgãos causam lesões nos hospedeiros intermediários, resultando na cisticercose. O homem pode também ser hospedeiro ocasional da T. solium e desenvolver a cisticercose, quando da ingestão acidental de seus ovos. Uma das medidas de controle desta zoonose é a inspeção sanitária de bovinos e suínos ao abate, evitando assim que os parasitas completem seu ciclo biológico. Assim, o complexo teníase-cisticercose, além de ser um grave problema de saúde pública, é também um problema econômico na agropecuária, visto que as carcaças podem ser condenadas quando da presença de formas larvares ou terem seu valor reduzido. A neurocisticercose é a forma mais grave desta zoonose no homem e seu diagnóstico é realizado por meios imunológicos e/ou por exames de imagens, que permitem a visualização dos das lesões no sistema nervoso central. Já a teníase é diagnosticada por meio da pesquisa de proglotes ou de ovos das tênias nas fezes, os quais são indistinguíveis morfologicamente. O objetivo do presente estudo foi avaliar a ocorrência de teníase humana por meio da análise dos resultados de exames coproparasitológicos rotineiramente realizados em laboratório privado de análises clínicas de um município paulista.
The taeniasis-cysticercosis complex is caused by the cestodes Taenia saginata and Taenia solium, which have man as their definitive and mandatory host and cattle and swine, respectively, as intermediate hosts. The presence of the adult form of these cestodes in the small intestine causes minor damage to humans, while the presence of the larval forms in tissues/organs causes damage to the intermediate hosts, resulting in cysticercosis. Man can also be an occasional host of T. solium and develop cysticercosis when ingesting its eggs. One of the measures to control this zoonosis is sanitary inspection of cattle and pigs at slaughter in order to prevent the parasites from completing their biological cycle. Thus, in addition of being a serious public health problem the taeniasiscysticercosis complex is also an economic problem once the carcasses with the larval forms can be condemned or have a reduced value. Neurocysticercosis is the most severe form of this zoonosis in man and its diagnosis is done by immunological method and/or by imaging exams, which allow the visualization of the lesions in the central nervous system. Taeniasis is diagnosed by searching for proglottids and/or tapeworm eggs in feces, which are morphologically indistinguishable. The objective of the present study was to evaluate the occurrence of human taeniasis by analyzing the results of the coproparasitological exams routinely performed in a private clinical analysis laboratory at a city in São Paulo state, Brazil.
