Avian orthoreovirus Avian orthoreovirus infections most frequently cause necrosis, hemorrhage, and inflammation within tendons and tendon sheaths, and around joints. This study aimed to evaluate the molecular evolution of the ARV lineages detected in Chinese commercial broiler farms. 343 (1), 25–35 (2005). 4. It causes a variety of diseases, such as viral arthritis, tenosynovitis, growth retardation, and chronic respiratory diseases [1, 2]. With regard to its structure, ARV has a unique double-layered icosahedral capsid that measures about 70–80 nm in diameter without the envelope Jan 10, 2025 ยท In the last decade, the emergence of variant strains of avian orthoreovirus (ARV) has caused an enormous economic impact on the poultry industry across China and other countries. The ARV virion averages 70–80 nm in size, containing a non-enveloped The genus Orthoreovirus currently contains five recognized members; the prototype Mammalian orthoreoviruses, the Avian orthoreoviruses, Baboon Orthoreovirus, and Reptilian orthoreoviruses. Virions is enclosed within a double-capsid structure with a diameter of 70–80 nm and its genome consists of 10 segments of double-stranded RNA (dsRNA) (Gouvea and Schnitzer, 1982). Rep. Avian orthoreoviruses are ubiquitous among poultry flocks and have been reported globally.
