Abstract
The present study aimed at determining the prevalence of porcine cysticercosis and associated risk factors for taeniosis in Iringa rural. A total of 110 households rearing pigs from sixteen villages were involved in a survey in which 308 pigs were examined for Cysticercus cysts by antemortem and postmortem methods. The risk factors for taeniosis were assessed and evaluated through questionnaires, interviews and by direct observation. Of 308 pigs examined by lingual palpation, 23 (7.5%, p<0.001) had cysticerci; the prevalence rates was higher in male pigs than female 16 (69.5%) and 7 (30.4%), respectively. Likewise the prevalence was higher in villages away from the main roads where there were pigs that customarily ran loose or fed human feaces. The triceps muscle had the highest number of cysts 44 (51.1%) and the diaphragm had the lowest 6 (6.9%). Of 4020 people who sought for treatment in five wards per month, 155 (21.8%) had history of intestinal worms, 6 (2.2%) consumed uninspected pork from peoples house, 82 (74.5%) lack tap water, 13 (12%) had no toilets and 40 (22.7%) practiced free range pig husbandry or tethering method. The findings from this study identified community behavioral, household hygiene and environmental practices that should be modified to prevent continued transmission of cysticercosis and taeniosis in Iringa rural district.
Highlights
Porcine cysticercosis is due to the establishment of the larva stage of Taenia solium in different parts of the body (Flisser et al, 2006)
The prevalence of PCC was higher in males than in female pigs 16 (69.5%) and 7 (30.5%), Table 3: Identified risk factors for human taeniosis (n = 110)
A total of 308 pigs were examined for T. solium cysticercosis in sixteen villages of Iringa rural
Summary
Porcine cysticercosis is due to the establishment of the larva stage of Taenia solium in different parts of the body (Flisser et al, 2006). It is acquired by ingestion of eggs released by human tapeworm carriers (Ngowi et al, 2007). The prevalence of porcine cysticercosis is reported to vary from one region to another (Ngowi et al, 2004). In Tanzania, the documentation of the disease is still scanty with available reports only from three districts namely; Mbulu District where the prevalence was 17.4% (Ngowi et al, 2007), Iringa rural and Mbinga district, with a prevalence of 8.4 and 16.9%, respectively (Boa et al, 2006)
