Newcastle disease is one of the serious diseases of poultry. It causes a great loss in poultry industry and

domestic village chickens. Since domestic chickens in villages are free ranging for food, the chance of contact

with wild birds which may act as a reservoir for many viral diseases is high.

The ELISA and Haemagglutination Inhibition (HI) test were used for the detection of antibodies against

Newcastle disease virus in 500 serum samples collected from chickens with no history of vaccination from

five regions in Sulaimani province during September and October 2006. Forty six percent of sera were

positive by ELISA and 34.4% by HI test. Chi-square and t-tests were used for statistical analysis. A good

correlation was observed between ELISA and HI titers (Correlation Coefficient=0.705205, T=3.80732) and

there was a statistically significant differences between ELISA and HI test at 95% confidence level (P<0.05).

It was found that 46% of the domestic village chickens have protective antibody and 53.9% of chickens

are susceptible to Newcastle disease virus infection.
