Abstract
The aim of this study is designed to determine the prevalence of AI virus type A and subtypes H9, H7 and H5 antibody in different localities in Sudan. During the period of 2003 to early 2006, a total of 1025 sera samples were randomly collected from young, growing and adult, apparently health, unvaccinated chicken flocks at Khartoum, Central, Northern, Eastern and Western States of Sudan. Using AGID test, AI type A antibody was detected in 692 (67.51%) of the tested samples. From type A positive sera, a total of 311samples (36 sera from each state) were examined to subtypes H9, H7 and H5 by means of haemagglutination inhibition (HAI) test. AI antibodies to subtypes H9 and H7 were detected in 141(45.33%) and 11(3.54%) of tested serum samples respectively. All samples tested negative (0%) for type H5.The risk factors of location, Age groups and strains are statistically associated with seropositivirty of Avian Influenza ( P-value <0.05). In conclusion: The results obtained confirmed the presence of AI type A antibody and sub types H9 and H7 in Sudan.
