Epidemiological Survey on Porcine Cysticercosis in Nay Pyi Taw Area, Myanmar

Abstract

Cross-sectional surveys were conducted to determine the prevalence and associated risk factors of Taenia solium cysticercosis in pigs within Nay Pyi Taw area, Myanmar. Meat inspection in three slaughterhouses, ELISA test, and questionnaire surveys were conducted in this study. Three hundred pigs were inspected in slaughterhouses and 364 pigs were randomly selected and examined from 203 households from three townships in Nay Pyi Taw area. The prevalence of porcine cysticercosis in meat inspection was 23.67% (71/300). Seroprevalence of T. solium cysticercosis in pigs in the study area was 15.93% (58/364). Significant associated risk factors with T. solium cysticercosis were gender (OR=3.0; 95% CI=1.7–5.4), increased age (OR=2.3; 95% CI=1.2–4.2), husbandry system (OR=5.1; 95% CI=2.4–11.2), feed type (OR=16.9; 95% CI=2.3–124.3), not using anthelmintics in pigs (OR=11.9; 95% CI=5.0–28.5), not using anthelmintics in owner (OR=2.5; 95% CI=1.4–4.4), no hand-washing before feeding (OR=31.5; 95% CI=4.3–230.9), and pork consumption of owner (OR=37.4; 95% CI=9.0–156.1) in the study area. This is the first report of porcine cysticercosis in Myanmar.
