Prevalence of porcine cysticercosis and risk factors for Taenia solium cysticercosis/taeniosis in three divisions of Busia District, Kenya.

摘要

The prevalence of T. solium in pigs was studied by antemortem lingual examination of pigs, while the prevalence of risk factors for cysticercosis and taeniasis was determined by administration of a standard questionnaire to households in three divisions of Busia District. Antemortem lingual examination and palpation of 93 pigs in Township division, 138 pigs in Funyula division and 62 pigs in Bundalangi division (n=293 of various ages) showed that 8 (9%) in Township division, 21 (15%) in Funyula division and 2 (3%) in Bundalangi division (mean 10.5%) had cysts. Those practising home slaughter with no official meat inspection were 27, 44 and 33% households in the divisions, respectively. Previous tapeworm experience was found in 64, 96 and 36 of the households in the divisions, respectively. Those with active tapeworm infections composed 13.6, 11 and 9% of the households in the divisions, respectively. In conclusion, porcine cysticercosis is prevalent in free range pigs in the three divisions of Busia District..
