Comparison of Laboratory Parameters in the Serum of SPF Chickens Infected with Different Iranian Genotypes of Infectious Bronchitis Virus
Background and Aims: Infectious bronchitis (IB), caused by infectious bronchitis virus (IBV), is an acute and highly contagious disease in chickens. IBV is considered mainly as a respiratory infection, other clinical manifestations, including renal, enteric and reproductive signs can be observed. Since there has been no study on evaluation of changes in biochemical parameters during IB infect...

متن کاملCross-immunity study of two experimentally oil-emulsion inactivated Infectious bronchitis vaccines in SPF chickens
A study has been carried out for determining of cross-immunity between Massachusetts (Mass) M41 and Iranian IR/773/2001 (793/B) strains of infectious bronchitis virus. Two groups of 20 three weeks old SPF chickens vaccinated subcutaneously with two oil-emulsions inactivated Infectious Bronchitis Vaccines (Mass M41 and Iranian IR/773/2001 strains) that had been manufactured in Razi institute in ...
متن کاملExperimental study on histopathological changes and tissue tropism of Iranian infectious bronchitis serotype 793/B-like virus in SPF chickens.
Avian infectious bronchitis virus (IBV) is prevalent in all countries with intensive poultry flocks. This disease is characterised primarily by respiratory signs, but some IBV strains may also infect other organs such as the intestinal and urogenital tracts. The aim of this study was to characterise the histopathological lesions and tissue tropism of Iranian isolate IR/773/2001(793/B) of avian ...
متن کاملEmergence of variant avian infectious bronchitis virus in India
Background: Infectious bronchitis virus (IBV) is the etiological agent of an acute and highly contagious disease. Infectious bronchitis (IB) affects chicken of all ages and poses major economic loses to the poultry industry worldwide. The continuous evolution of the spike protein (S1) of IBV is responsible for the prevalence of many serotypes/genotypes around the world. Multipl...
