[Frequency of anti-Cysticercus cellulosae antibodies in individuals from five counties in the Northern region of Brazil]. / Freqüência de anticorpos anti-Cysticercus cellulosae em indivíduos de cinco municípios da região Norte do Estado do Paraná-Brasil.

ABSTRACT

An epidemiological and serological study was carried out on a sample of 2,180 individuals, in five counties in the north of Paraná State-Brazil, using the indirect immunofluorescence test to detect anti-Cysticercus cellulosae antibodies. These individuals, 69 (3.2%) showed significant titers of antibodies. No single significant difference between the proportion of reactivity in Sarandi (6.6%) and in Marialva (4.7%) was observed (Z = 1,319, P = 0.0936), but it was significantly higher than that observed in Mandaguaçu, Paiçandu and Maringá (P < 0.01). Of these individuals, 47.9% were within 21-49 years old and 79.4% were of female sex. "Headache" (70.6%), "faintness" (57.4%), and "convulsions" (7.4%) were among the most frequent by reported, moreover, cases of Taenia infections (22.1%) and the custom of eating uncooked beef (41.2%) or pork (27.9%) and meat containing cysticerci (25.0%) were also related.
