التحري المصلي للإصابة بفيروس الأنفلونزا الطيور (H9N2)‎ في الإنسان

Abstract EN

The study aim to investigate the infection with the locality isolates H9N2 avian influenza virus in human by using haemagglutination inhibition test, complement fixation test and ELISA test locally prepared kits.

Antibodies of avian influenza virus (H9N2) are diagnosed in the sera of persons working and dealing with infected chickens’ flock from which the H9N2 virus was isolate.

This 5 sera samples were given positive result in HI test in a titer rate of (275.6) (inhibitor antibodies of heamagluttination), in amount range of (32- 512).

The ELISA and the Complement fixation tests were used to detect the avian influenza virus (H9N2) antibodies in the sera of working persons.

In addition the anti-avian influenza virus antibodies were detected in (40) Sera samples of peoples were living in direct contact with the chickens and other birds.

The sera samples were tested by ELISA, CF and HI tests, and the results showed that the highest percentage (85 %.) of positive sera was in ELISA test.
