Comparison of Kato-Katz, PCR and coproantigen for the diagnosis of taeniasis.

Four methods were compared for the diagnosis of human taeniasis caused by Fecal samples from persons living in a endemic region of Madagascar were examined for taeniid eggs by the Kato–Katz method. Subsequently, samples positive ( = 16) and negative ( = 200) for eggs were examined by (i) amplification of the fragment of small subunit of the mitochondrial ribosomal RNA (S) gene using conventional polymerase chain reaction (PCR) and (ii) a nested PCR of a fragment of the gene. Additionally, 12 egg-positive and all egg-negative samples were tested for coproantigen detection.

Confirmation by necropsy of a high prevalence of porcine cysticercosis in a rural district of Madagascar.

Neurocysticercosis is recognized as an important health issue in the Malagasy population. To date, investigations into prevalence of infection with the causative agent, , in the parasite's natural animal intermediate hosts, have relied on serological methods which have been found to be non-specific. We determined the prevalence of porcine cysticercosis among pigs from a contiguous area of the Betafo and Mandoto administrative districts, Vakinankaratra Region, Madagascar.
