ABSTRACT
An immunodot test was implemented to detect pigs with antibodies against
Cysticercus cellulosae. The antigen was prepared with
Cysticercus cellulosae and diluted in tris buffer saline (TBS). Then it was spotted in volumes of 10 µl onto the nitrocellulose paper which then was blocked, fixed and incubated at room temperature. Pig's serum was diluted in TBS 7.5 pH containing gelatin and tween 20; then it was added followed by biotin-avidin peroxidase labeled antibody directed toward the pig's IgG. The addition of a substrate resulted in the formation of a purple color when the test was positive. The immunodot test showed a concordance of 95.4%, a sensitivity of 91,1% and a specificity of 96.9% when the results where compared with the results of the postmortem sanitary inspection. The immunodot test described in this report is simple, cheap and provides objetive results for the serodiagnosis of porcine cysticercosis.
