ABSTRACT
Considering the impact of cysticercosis on public health, especially the neurologic form of the disease, neurocysticercosis (NC), we studied the frequency of positivity of anti-Taenia solium cysticercus antibodies in serum samples from 1,863 inhabitants of Cássia dos Coqueiros, SP, a municipal district located 80 km from Ribeiräo Preto, an area considered endemic for cysticercosis. The 1,863 samples were tested by enzyme linked immunosorbent assay (ELISA) using an antigenic extract from Taenia crassiceps vesicular fluid (Tcra). The reactive and inconclusive ELISA samples were tested by immunoblotting. Of the 459 samples submitted to immunoblotting, 40 were strongly immunoreactive to the immunodominant 18 and 14 kD peptides. Considering the use of immunoblotting as confirmatory due to its high specificity, the anti-cysticercus serum prevalence in this population was 2.1 percent

Objetivo: Determinar a prevalência de protozoários e helmintos, além de identificar as variáveis sociais de risco para a parasitose intestinal em escolares de primeira série de uma escola pública de Campinas, Säo Paulo. Métodos: Estudo transversal, descritivo e analítico, baseado em dados pessoais e sociais levantados em entrevista e em pesquisa de amostra de fezes de 146 crianças para Ancylostomatidae, Ascaris lumbricoides, Endolimax nana, Entamoeba coli, Entamoeba histolytica, Entero bius vermicularis, Giardia lamblia, Hymenolepis nana, Iodamoeba bütschlii, Schistosoma mansoni, Strongyloides stercoralis, Taenia sp e Trichuris trichiura. Resultados: O exame protoparasitológico mostrou maior prevalência de Ascaris lumbricoides (12,3 por cento) e Giardia lamblia (8,2 por cento). No total, a prevalência de parasitose foi de 30,8 por cento...
