Prevalence of porcine cysticercosis in Vellore, South India

Background: Porcine cysticercosis is acquired by pigs through consumption of human faeces containing Taenia solium ova and indicates the presence of active transmission of the parasite between pigs and humans. Methods: The prevalence of porcine cysticercosis was assessed by an antigen ELISA and enzyme linked immunoelectrotransfer blot (EITB) for antibodies in rural and urban areas of southern India. Results: Of the 112 porcine blood samples, 13 (11.6%) were positive for cysticercal antigens and the free-range pigs were 3.6 times more likely to be infected than the slaughtered pigs and 67 (59.8 %) tested positive for serum antibodies indicating high exposure to T. solium eggs. Conclusion: The high prevalence of porcine cysticercosis recorded in the study areas mandates public health measures, which includes meat inspection
