BookPublisher: 1986Subject(s): Department of MicrobiologyDDC classification: 0287,T Dissertation note: Avian Infectious Bronchitis (AIB) is an important disease of chickens affecting birds of all ages, both sexes and, all breeds. The disease is more severe in broilers.
It occurs .in two clinical forms i.e. the respiratory form and the reproductive form. In the first form of disease the mortality is an important factor, while in the latter form the reproductive tract and reproduction of birds are affected. The economic significance of Avjan Infectious Bronchitis lies in the fact that it causes moderate to heavy mortality and marked drop in egg production, increased number of small size, misshaped, and poor quality eggs; low hatchability, death in shell and early chick mortality.
The present work was planned to investigate the serological incidence of Avian Infectious Bronchiti and to have a knowledge about the important serotypes provlent in Pakistan. The sera of 200 broilers from various broiler markets and poultry farms of Lahore was tested against 4 serotypes of Aviari Infectious Bronchitis virus i.e; 1assachusets, Connecticut, Arkansas and JMK using haemsgglutination inhibition test.
The work has shown that Avjan Infectious - ronchitis is present in broilers in and around Lahore, as antibodies against three important serotypes i.e. Massachusetts, Connecticut and Arkansas were detected in 11.5% sera of 200 tested birds.
Further work on large scale using birds from different parts of the country is recommended to determine the exact status of this disease in Pakistan.
