Canine distemper virus

Antibody study in canine distemper virus nucleocapsid protein gene-immunized mice

B. Yuan, Li, X. Y., Zhu, T., Yuan, L., Hu, J. P., Chen, J., Gao, W., and Ren, W. Z., Antibody study in canine distemper virus nucleocapsid protein gene-immunized mice, vol. 14, pp. 3098-3105, 2015.

The gene for the nucleocapsid (N) protein of canine distemper virus was cloned into the pMD-18T vector, and positive recombinant plasmids were obtained by enzyme digestion and sequencing. After digestion by both EcoRI and KpnI, the plasmid was directionally cloned into the eukaryotic expression vector pcDNA; the positive clone pcDNA-N was screened by electrophoresis and then transfected into COS-7 cells. Immunofluorescence analysis results showed that the canine distemper virus N protein was expressed in the cytoplasm of transfected COS-7 cells.

Phylogenetic analyses of the hemagglutinin gene of wild-type strains of canine distemper virus in southern Brazil

F. J. Negrão, Gardinali, N. R., Headley, S. A., Alfieri, A. A., Fernandez, M. A., and Alfieri, A. F., Phylogenetic analyses of the hemagglutinin gene of wild-type strains of canine distemper virus in southern Brazil, vol. 12, pp. 2549-2555, 2013.

This study examined the phylogenetic relationship of strains of canine distemper virus (CDV) collected from Paraná State, Brazil, based on the hemagglutinin gene. Urine samples were collected from 4 dogs from northern Paraná State that demonstrated clinical manifestations of canine distemper. The participation of CDV was initially confirmed by RT-PCR targeting the nucleocapsid protein, after which the complete hemagglutinin gene was sequenced from each sample. Sequences were deposited in and compared with those already in GenBank.
