Experimental co-infection of infectious bronchitis and low pathogenic avian influenza H9N2 viruses in commercial broiler chickens	2017-06-30		.txt	text/plain	3787	202	52	title: Experimental co-infection of infectious bronchitis and low pathogenic avian influenza H9N2 viruses in commercial broiler chickens Avian influenza H9N2 and H5N1 subtypes, Infectious bronchitis virus (IBV), and virulent Newcastle disease virus (vNDV) have been frequently isolated from different broiler chicken flocks (Hassan et al., 2016) . Experimentally infected commercial broilers with classical and variant IBV and vaccine IBV strains in presence or absence of AIV-H9N2N2 infection were monitored for clinical outcomes, virus shedding, postmortem and histopathological lesions. Histopathologically, trachea in all mixed infection groups including the AIV-H9N2 with vaccine IBV strain showed severe changes comparable to the milder changes in single classical or variant IBV challenged groups (Purcell et al., 1976) . Similarly, in this study, significant increases of AIV-H9N2 virus shedding with classical IBV infection especially at 2 and 5 DPI and with the variant and vaccine IBV strains co-infections up to 7 DPI were observed.	./cache/cord-303794-fn3jkiil.txt	./txt/cord-303794-fn3jkiil.txt
