Reassortment among picobirnaviruses found in wolves
We conducted a viral metagenomics study in diarrheic free-ranging wolves in Portugal, revealing for the first time the presence of reassortant picobirnaviruses. These viruses shared identical capsid segments together with diverse RNA-dependent RNA polymerase segments. Even though causality between these picobirnaviruses and diarrhea could not be established, the study nonetheless confirms for the first time that wolves are a potential reservoir for picobirnaviruses, which might play a role as enteric pathogens.
