Colheu-se sangue de sete suínos infectados com ovos de Taenia solium, semanalmente, durante 140 dias, para realizar ELISA no soro, utilizando antígeno de escólex (Es-Tso) de C. cellulosae. Em todos os animais, após o 21º dia pós-infecção, houve incremento significativo de anticorpos IgG, que assim se mantiveram até o final do experimento. A sensibilidade do ELISA variou entre 87,5 e 100%. À necropsia, foram identificados 238 cisticercos. Seis suínos apresentaram pelo menos um cisto no coração, língua ou masseter. Não se observou correlação entre concentração de anticorpos e número de cisticercos identificados.<br>Blood samples from seven swines infected with eggs of Taenia solium, were collected weekly during a period of 140 days. The ELISA was carried out in serum, using antigen from Cysticercus cellulosae scolex (Es-Tso). The antibody levels for all animals significantly increased and maintained constant from the 21th day post-infection to the end of the experiment. The sensitivity of the ELISA test averaged between 87.5% and 100%. At the necropsy, 238 cysticerci were identified. Six swines presented at least one cysticercus in one of the organs: heart, tongue or masseter. No correlation between concentration of antibodies and number of identified cysticerci at necropsy, was observed.
