Mammalian orthoreoviruses (MRVs) are widespread and infect virtually all mammals. We report here the first case of a natural mutant and reassortant serotype 3 reovirus from mink in China, known as MRV3 SD-14. Whole-genome sequence analysis showed that the MRV3 SD-14 may have resulted from a reassortment involving MRVs that infected swine, humans and mink. Interestingly, the S1 segment, which encodes the viral attachment protein σ1, which influences viral virulence and cell tropism in the host, had a stop codon mutation at amino acid 246. Surveillance of the virulence and evolution of MRVs in humans and other animals deserves more attention.

African horse sickness (AHS) is an acute, fatal, contagious disease of animals of the family Equidae and is caused by infection with the African horse sickness virus (AHSV). Based on the outer capsid protein VP2, AHSV is classified into nine serotypes (AHSV-1 to -9) with little or no serological cross-reactivity between them. In 2020, AHS outbreaks caused by AHSV-1 were reported in Thailand and Malaysia, marking the first occurrences of AHS in Southeast Asia.

Fowl adenovirus serotype 4 (FAdV-4) is the main causative agent of hydropericardium hepatitis syndrome (HHS), which has resulted in huge economic losses to the poultry industry in recent years. Hence, a rapid and simple visual detection method is needed for identification of FAdV-4. In this study, three multienzyme isothermal rapid amplification (MIRA) assays, basic MIRA, MIRA-qPCR and MIRA-LFD were developed for detection of FAdV-4.

Bluetongue virus (BTV) is a prevalent midge-borne pathogen that infects ruminant species worldwide. BTV infections range from asymptomatic to lethal, with mechanisms that determine the severity of infection remaining largely undefined. Although it is relatively poorly understood, the immune response to BTV infection is thought to be critical for both the propagation of disease as well as the resolution of infection.
