Isolation, tissue distribution and molecular characterization of two recombinant canine coronavirus strains.

ABSTRACT: Canine coronavirus (CCoV) is an enveloped RNA virus, responsible for gastrointestinal infection in dogs. To date, two different CCoV genotypes have been recognized, CCoV type I and CCoV type II. Recently, CCoV type II strains of potential recombinant origin with transmissible gastroenteritis virus (TGEV) were detected and characterized as a new subtype (CCoV-IIb) of canine coronavirus, in order to be differentiated from the "classical" CCoV type II strains (CCoV-IIa). In the present study, two CCoV-IIb strains were detected in the faeces and internal organs of two puppies, which died after presenting gastrointestinal symptoms. Mixed infection of both subtypes (CCoV-IIa/IIb) was detected in the faeces, while only CCoV-IIb was detected in the organs. Puppies were also infected by canine parv
