This isn’t apt to be linked to vaccination exclusively, since seroprevalences in cattle and little ruminants were likewise high or lower in the particular areas (0C4% for Area Three and 20C40% for North Shewa Area), and cattle weren’t apt to be vaccinated. The OR of seropositivity for goats compared to cattle ranged from 1.9 [95% confidence interval Ezogabine (CI): 1.3C2.7; 0.001] to 2.2 (95% CI: 1.5C3.1; 0.001) when doubtful results were excluded or classified while negative, respectively. When doubtful results were classified as positive, association between seropositivity and animal varieties was not significant ( 0.05). Our results suggest to further investigate cattle as sentinel animals for PPR monitoring. 0.05. Results The proportion of positive results by varieties and by Zone when doubtful laboratory results were classified as positive, bad, or excluded is definitely presented in Table 1. The odds of seropositivity for the combined results of the three animal varieties in North Shewa Zone compared to Zone Three ranged from 19 to 27 (Table 1), for the three scenarios of how doubtful results were classified. The odds of seropositivity for goats compared to cattle was 2.2 [95% confidence interval (CI): 1.5C3.1], 1.3 (95% CI: 0.9C1.8), and 1.9 (95% CI: 1.3C2.7) when doubtful results were classified while negative, positive, or excluded, respectively. Zone by animal varieties interaction (data not shown) was not statistically significant ( 0.05) in the three scenarios considered for the doubtful values; results reported here therefore represent the main effects of zone and animal varieties adjusted for the effect of the additional in the multivariable logistic regression models. Table 1 Descriptive and logistic regression analyses results comparing seropositivity (dichotomous end result recorded as seropositive or seronegative) of peste des petits ruminants between sedentary highland (North Shewa Zone, Amhara region) and nomadic lowland (Zone Three, Afar region) livestock production systems in Ethiopia, December 2005CJune 2006. 0.05). Ezogabine The difference between the present results and literature may be due to different sampling methods in the different studies that affect their representativeness. Field collection of data and the use of probability sampling designs are challenging in Ethiopia because of poor infrastructure, cultural differences BMPR1B that may create a insufficient co-operation from livestock owners and intervals of popular climatic circumstances (22). The field data from our research did not enable an in depth evaluation from the role from the herd size, varieties composition Ezogabine from the herds as well as the creation program (sedentary highland and lowland pastoral nomadic) for the seroprevalence prices in both regions which might also clarify the difference between outcomes of our research as well as the literature. Seasonality of the condition also may have affected the outcomes as the Ezogabine period of time of the analysis was limited and outbreaks are more frequent during the main rainy season which typically lasts from March to October in Ethiopia (21). Thus, presence of active PPR outbreaks at the time of serum sample collection in one or both zones studied also could have affected our results. However, samples were obtained from apparently healthy animals and there was no indication of PPR outbreak during the field sampling. It may also be due to differences in prior vaccination status of the animals. The higher seropositivity observed in the highland zone in the present work can reflect a higher prior vaccination rate in the zone Ezogabine that are generally more accessible as several mass vaccination campaigns have occurred in Ethiopia between 2005 and 2011 (16).
