Bovine cysticercosis and human teniasis with public health implication at Asella town, Arsi Zone of Oromia Regional State, Ethiopia

Abstract

The aim of study was to determine statues of bovine cystiercosis and human taeniasis in Asella, Arsi Zone of Oromia Regional State, Ethiopia. Simple randomly sampling followed by detailed meat inspection for cyst distribution with cyst count and variability test was done at Asella Municipal Abattoir. Questionnaire administration surveys was conducted on voluntarily in habitants of Asella town. Out of 450 examined animal, 22 (4.9%) were infected with C. bovis showing significantly higher in younger 8.2% (OR=3.4, 95%CI: 1.4-8.7) and in cross breed 14.2% (OR=4.3, 95%CI: 1.3-14.2) then their counters (p<0.05) but neither between sex nor among animals body condition (p>0.05). A total of 63 cyst consisting of 30 (47.6%) viable and 33 (52.4%) non-viable were recovered. Cysts count was 28.6%, 23.8%, 20.6%, 17.5%, 6.4% and 3.2% in the tongue, triceps muscle, heart, masseter muscle, liver and diaphragm respectively. In high viable cysts (61.1%) were found in the tongue. Out of 125 respondents, 89 (71.2%) had contracted taeniasis infection at least once in their life time. Men (OR=8.3, 95%CI: 1.9-36.4), occupationally high-risk groups (OR=2.1, 95%CI: 0.5-8.2), married persons (OR=7.1, 95%CI: 1.7-29.3), raw meat consumers (OR=35.2, 95%CI: 6.3- 196.7) and low level of taeniasis/cysticercosis complex knowledge (OR=4.261, 95%CI: 1.2-15.6) were contracted taeniasis at higher risk than their counter groups (p<0.05). Age and educational background were no effect on the difference (p>0.05). The data indicated Taenia saginata/cysticercosis is prevalent in the study area which needs due attention for public awareness and strict routine meat inspection to safe guard public health and promote beef industry.
