an indirect enzyme–linked immunosorbent assay (elisa) was developed for screening of antibody to avian infectious bronchitis virus (ibv). antigen was prepared from whole-purified ibv massachusetts serotype (br 801 strain). optimum dilution with minimum background for antigen concentration, rabbit anti-chicken conjugate and sera in developed elisa was determined 0.1μg/ml, 1:3000 and 1:100, respe...
An avian infectious bronchitis virus (IBV) was detected from trachea swabs of chickens in Hubei province, China, in 2016. The complete genome of the IBV strain, CK/CH/HB/2016, was characterized and analyzed to better understand IBV epidemiology in China.
We describe the emergence of a nephropathogenic avian infectious bronchitis virus (IBV) with a novel genotype in India. The Indian IBV isolate exhibited a relatively high degree of sequence divergence with reference strains. The highest homology was observed with strain 6/82 (68%) and the least homology with strain Mex/1765/99 (34.3%).
Avian coronavirus is the causative agent of infectious bronchitis in chickens, leading to multisystemic disease that might be controlled if adequate vaccine strains are used. This paper reports the first complete genome sequence of a Brazil type of this virus (27,615 nucleotides [nt]) isolated from the kidneys of a chicken.
