Abstract:

Chicken anemia virus (CAV) is a single-stranded circular DNA virus classified within the genus Gyrovirus of the family Anelloviridae. The disease caused by CAV is predominantly characterized by aplastic anemia, lymphatic atrophy, and concurrent immunosuppression. The widespread occurrence of CAV has led to significant economic detriment in the global poultry sector. This review offers a thorough overview of advancements in CAV, encompassing its genomic features and transmission, clinical signs and pathogenicity, diagnostic methodologies, prevalence, and current antiviral strategies, which will provide a valuable resource for future research and the effective management of this pathogen.

Viral Mutations

Viral Mutations

A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...
