Seroprevalence of Newcastle Disease Virus Antibodies in Village Chickens in Kersana-kondalaity District, Ethiopia

摘要

A cross-sectional study on sero-prevalence of Newcastle disease virus (NDV) antibodies in villagechickens in Kersana-kondalaity district was conducted using Blocking-Enzyme Linked Immunosorbent Assay(b-ELISA) from January to March 2009. A total of 355 chicken sera were randomly collected from eight peasantassociations (PA). An overall sero-prevalence of 5.6% (3.2-8.0% at 95 % CI) was found and five (62.5%) of theeight PA sampled had chickens that were positive for antibodies against NDV. The prevalence in each PAranges from 0% to 28.1% and the highest prevalence (28.1%) was found at Harbu PA, located just near to marketarea. The prevalences of chicken’s serum antibody in the highland and lowland area were 0.9% and 7.8%respectively. Statistically significant (p0.005) for male and female. The study showed thatmajority of the chicken population in the study area were susceptible to the pathogenic NDV infection. Thus,routine vaccination program is recommended.
