| dc.description.abstract | A cross-sectional study was carried out in four district of Afar region from November 201I to April 2012 to determine the prevalence of brucel1OSiS in smal1 ruminants and camels and to identify. risky practice that would faCi1itate the transmission 0f zoonoses. to humans . The study involved testing 324 sheep, 726 goats and 461 camels and interviewing 120 livestock owner:. Modified Rose Bengal Plate Test (mRBPT) and Complement Fixation Test (CFT) were used as screening and confirmatory tests, respectively. The SPSS 16.0 software was used to establish the overall prevalence for each species. while potential risk factors for seropositivity were analyzed using a multivariable logistic regression analysis. The results showed that 7. I% of the sheep, 5.4% of the camels and 13.6% of the goats (X~= 24.9 L P<0.05) and 5. I I % and 24% of the small ruminant and camel herds tested had antibodies against Brucella species. District level seroprevalence ranged from 3.6% to 13.6%.3.3% to 6.7% and 11.7% to 15.5% in sheep. goats and camels, respectively. The final logistic regression model for small ruminants identified goats (OR=2.36; 95% CL: 1.46-3 .82) showing higher risk of brucella infection when compared to sheep. In addition small ruminants greater than two years (OR= 3. I 32; 95%CI: 1.6-6 .15), females (OR= 1.79; 95%CI: 1.02-3.13) and larger than 30 herd size (OR=2.04; 95%CI: 1.35-3 .1) arc at higher risk of brucella infection than their counter categories. Moreover in camels. herd size> 20 animals (OR = 2.8; 95% CI: 1.16-6.62) and greater than four years (OR 4.9: 95% CL: 1.45- 16.82) show higher risk of brucella infection when compared to small herds and those ~ 4 years old. The questionnaire survey showed that most respondents had no accurate knowledge about the transmission or zoonoses. It was also found that some of their practice would potentially facilitate the transmission of' zoonotic pathogens to human. such as handling of abortcd materials and raw animal product consumption The results of this study demonstrated that livestock brucellosis is widely prevalent in the study areas. Hence. the study suggests the need for implementing control measures and raising public awareness on prevention methods of brucellosis. | |
