| co-circulation of canine coronavirus i and iia/b with high prevalence and genetic diversity in heilongjiang province, northeast china. | to trace the evolution of canine coronavirus (ccov), 201 stool samples from diarrheic dogs in northeast china were subjected to reverse transcription-polymerase chain reactions (rt-pcrs) targeting the partial m and s genes of ccov, followed by an epidemiological analysis. m gene rt-pcrs showed that 28.36% (57/201) of the samples were positive for ccov; of the 57 positive samples, ccov-i and ccov-ii accounted for 15.79% (9/57) and 84.21% (48/57), respectively. a sequence comparison of the partial ... | 2016 | 26771312 |
| co-circulation of the rare cpv-2c with unique gln370arg substitution, new cpv-2b with unique thr440ala substitution, and new cpv-2a with high prevalence and variation in heilongjiang province, northeast china. | to trace evolution of canine parvovirus-2 (cpv-2), a total of 201 stool samples were collected from dogs with diarrhea in heilongjiang province of northeast china from may 2014 to april 2015. the presence of cpv-2 in the samples was determined by pcr amplification of the vp2 gene (568 bp) of cpv-2. the results revealed that 95 samples (47.26%) were positive for cpv-2, and they showed 98.8%-100% nucleotide identity and 97.6%-100% amino acid identity. of 95 cpv-2-positive samples, types new2a (ser ... | 2015 | 26348721 |
