Prevalence of cysticercosis in epileptics and members of their families in Burundi.

In the province of Bururi in Burundi, 103 epileptics and 72 control subjects from the same households were examined for cysticercosis. Antigen was detected by enzyme-linked immunosorbent assay in 4.9% of epileptic persons and in 4.2% of controls. Antibody was detected by enzyme-linked electroimmunotransfer blot assay (EITB) in 11.7% of epileptics and in 2.8% of controls. Neither difference was statistically significant, nor was a history of taeniasis significantly more frequent in epileptics than in controls. However, cysticercosis was significantly more frequently diagnosed by EITB in people with a history of taeniasis than in those without such a history. The prevalence of taeniasis in schoolchildren ranged between 0 and 1.0%. Meat inspection detected cysticercosis in 2% and 39% of pigs in 2 localities, respectively.
