Our data provide evidence that CCoV-I, CCoV-IIa, and CCoV-IIb strains co-circulate in the diarrhoetic dogs in northeast China, high co-infection rates with CaKV and CPV-2 were observed, and the CCoV-II strains exhibited high prevalence and genetic diversity. A phylogenetic analysis using partial S gene sequences demonstrated that the 26 CCoV-IIa strains were closely related to three reference strains, 5281 (Japan), TN-449 (USA), and 1086-IIa (Brazil), and differed genetically from reference strains from China and other countries (Fig 2A) . This result demonstrated that vaccination for other canine viruses did not effect CCoV infections in the dog population in Heilongjiang province, northeast China. ./cache/cord-267189-xq70rn1j.txt ./txt/cord-267189-xq70rn1j.txt
