- ... Extinct from nature, captive young Alagoas curassows (Pauxi mitu) were found agonizing or dead with respiratory disease. Intranuclear inclusion bodies were found in the epithelia of the trachea, associated with marked necrotic tracheitis. An Aviadenovirus was isolated in chicken eggs and characterized genetically with 99% identity to the fowl Aviadenovirus A, as based on the hexon protein gene. Th ...

- ... 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 ...
