- ... Infectious bronchitis virus (IBV) is a persistent sanitary problem for the South American poultry industry despite extensive vaccination. The IBV single-stranded RNA genome has high rates of mutation and recombination that generate a notorious virus variability. Since most IBV vaccines are type-specific, there is a need for constant surveillance of the circulating lineages and knowledge about thei ...

- ... Infectious bronchitis virus (Gammacoronavirus, Coronaviridae) is a genetically variable RNA virus (27.6kb) that causes one of the most persistent respiratory disease in poultry. The virus is classified in genotypes with different epidemiological relevance and clinical implications. The present study reports the development and validation of specific RT-qPCR assays for the detection of two major IB ...

- ... Twenty infectious bronchitis virus isolates were recovered from broilers and layers in different outbreaks amongst commercial poultry flocks in different geographic regions of Argentina from 2001 to 2008. The viruses were isolated from the tracheas, lungs, and caecal tonsils of birds that were showing respiratory signs. Further analysis based on their nucleotide and amino acid sequences in hyperva ...
