Variant Infectious Bronchitis Virus Isolated From Indiana Chickens

Evolution of New Variant Strains of Infectious Bronchitis Virus Isolated from Broiler Chickens

In order to investigate the prevalence and track the genetic evolutions of the circulated infectious bronchitis virus (IBV) strains and their prevalence in Assiut, Egypt, partial S1 gene amplification and sequencing were done during 2013-2014. Three infectious bronchitis virus (IBV) strains with the following accession numbers (KR003438, KR003439 and KR003440 respectively) were detected from 21...

Isolation and Identification of Infectious Bronchitis Virus from Commercial Chickens

Emergence 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...

Characterization of an avian infectious bronchitis virus isolated in China from chickens with nephritis.

One IBV isolate, SC021202, was isolated from the kidneys of the infected young chickens by inoculating embryonated eggs, and its morphology, physiochemical and haemagglutonating properties were detected. Virulence of the isolate SC021202 was determined with specific pathogen-free (SPF) chicken inoculation. Nucleotide acid sequence of S1 gene of the isolate SC021202 was further sequenced and ana...
