Abstract
Canine distemper virus (CDV) is a pathogen which affects members of the Canidae family, causing an acute, often fatal, systemic disease. CDV is an RNA virus of the family Paramyxoviridae that contains two envelope glycoproteins: F and HA. In this study, we focused on the envelope glycoprotein F as the main target for neutralizing antibodies produced after infection or vaccination. The complete coding region of the protein (60 kDa) was expressed in the methylotrophic yeast Pichia pastoris, obtained in a recombinant form and secreted to the culture medium. Later, to analyze its immunogenicity, the protein was combined with an oily adjuvant and used to inoculate mice. The results provide evidence supporting a potential application of this recombinant protein as a subunit vaccine.

Abstract
During 2007-2014, 84 out of 236 (35.6%) samples from domestic dogs submitted to our laboratory for diagnostic purposes were positive for Canine Distemper Virus (CDV), as analyzed by RT-PCR amplification of a fragment of the nucleoprotein gene. Fifty-nine of them (70.2%) were from dogs that had been vaccinated against CDV. The full-length gene encoding the Fusion (F) protein of fifteen isolates was sequenced and compared with that of those of other CDVs, including wild-type and vaccine strains. Phylogenetic analysis using the F gene full-length sequences grouped all the Argentinean CDV strains in the SA2 clade. Sequence identity with the Onderstepoort vaccine strain was 89.0-90.6%, and the highest divergence was found in the 135 amino acids corresponding to the F protein signal-peptide, Fsp (64.4-66.7% identity). In contrast, this region was highly conserved among the local strains (94.1-100% identity). One extra putative N-glycosylation site was identified in the F gene of CDV Argentinean strains with respect to the vaccine strain. The present report is the first to analyze full-length F protein sequences of CDV strains circulating in Argentina, and contributes to the knowledge of molecular epidemiology of CDV, which may help in understanding future disease outbreaks.

Abstract
Canine distemper (CD), caused by canine distemper virus (CDV) is a highly contagious disease that infects a variety of carnivores. Sequence analysis of CDVs from different geographical areas has shown a lot of variation in the genome of the virus especially in haemagglutinin gene which might be one of the causes of vaccine failure. In this study, we isolated the virus (place: Ludhiana, Punjab; year: 2014) and further cloned, sequenced and analyzed partial haemagglutinin (H) gene and full length genes for fusion protein (F), phosphoprotein (P) and matrix protein (M) from an Indian wild-type CDV. Higher sequence homology was observed with the strains from Switzerland, Hungary, Germany; and lower with the vaccine strains like Ondersteport, CDV3, Convac for all the genes. The multiple sequence alignment showed more variation in partial H (45 nucleotide and 5 amino acid substitutions) and complete F (79 nucleotide and 30 amino acid substitutions) than in complete P (44 nucleotide and 22 amino acid substitutions) and complete M (22 nucleotide and 4 amino acid substitutions) gene/protein. Predicted potential N-linked glycosylation sites in H, F, M and P proteins were similar to the previously known wild-type CDVs but different from the vaccine strains. The Indian CDV formed a distinct clade in the phylogenetic tree clearly separated from the previously known wild-type and vaccine strains.

Abstract
Canine distemper (CD) is a highly contagious, often fatal, multisystemic, and incurable disease in dogs and other carnivores, which is caused by canine distemper virus (CDV). Although vaccines have been used as the principal means of controlling the disease, CD has been reported in vaccinated animals. The hemoagglutinin (H) protein is one of the most important antigens for inducing protective immunity against CD, and antigenic variation of recent CDV strains may explain vaccination failure. In this study, a new CDV isolate (TM-CC) was obtained from a Tibetan Mastiff that died of distemper, and its genome was characterized. Phylogenetic analysis of the H gene revealed that the CDV-TM-CC strain is unique among 20 other CDV strains and can be classified into the Asia-1 group with the Chinese strains, Hebei and HLJ1-06, and the Japanese strain, CYN07-hV. The H gene of CDV-TM-CC shows low identity (90.4 % nt and 88.9 % aa) with the H gene of the classical Onderstepoort vaccine strain, which may explain the inability of the Tibetan Mastiff to mount a protective immune response. We also performed a comprehensive phylogenetic analysis of the N, P, and F protein sequences, as well as potential N-glycosylation sites and cysteine residues. This analysis shows that an N-glycosylation site at aa 108-110 within the F protein of CDV-TM-CC is specific for the wild-type strains (5804P, A75/17, and 164071) and the Asia-1 group strains, and may be another important factor for the poor immune response. These results provide important information for the design of CD vaccines in the China region and elsewhere.

Abstract
A multiplex reverse transcription-nested polymerase chain reaction (RT-nPCR) method was developed for the detection and differentiation of wild-type and vaccine strains of canine distemper virus (CDV). A pair of primers (P1 and P4) specific for CDV corresponding to the highly conserved region of the CDV genome were used as a common primer pair in the first-round PCR of the nested PCR. Primers P2 specific for CDV wild-type strains, were used as the forward primer together with the common reverse primer P4 in the second round of nested PCR. Primers P3, P5 specific for CDV wild-type strain or vaccine strain, were used as the forward primer together with the common reverse primer P4+P6 in the second round of nested PCR. A fragment of 177 bp was amplified from vaccine strain genomic RNA, and a fragment of 247 bp from wild-type strain genomic RNA in the RT-nPCR, and two fragments of 247 bp and 177 bp were amplified from the mixed samples of vaccine and wild-type strains. No amplification was achieved for uninfected cells, or cells infected with Newcastle disease virus (NDV), canine parvovirus (CPV), canine coronavirus (CCV), rabies virus (RV), or canine adenovirus (CAV). The RT-nPCR method was used to detect 30 field samples suspected of canine distemper from Heilongjiang and Jilin Provinces, and 51 samples in Shandong province. As a result of 30 samples, were found to be wild-type-like, and 5 to be vaccine-strain-like. The RT-nPCR method can be used to effectively detect and differentiate wild-type CDV-infected dogs from dogs vaccinated with CDV vaccine, and thus can be used in clinical detection and epidemiological surveillance.

Abstract
Background Although the presence of Asia 2 group of canine distemper virus (CDV) was known by the sequencing and phylogenetic analysis of hemagglutinin (H) gene, the fusion (F) protein gene sequence of Asia 2 group had not been identified. So, the sequence analysis of F gene was carried out to elucidate the genotypic varaitons among Asian isolates. Results The phylogenetic analysis of F and H gene sequences from fourteen CDV isolates obtained from diseased dogs in Japan and Thailand indicated that the F genes had a new initiation codon and extra 27 nucleotides upstream of the usual open reading frame (ORF) and the F proteins had extra 9 amino acids at the N-terminal position only in Asia 2 isolates. On the contrary, the Asia 1 isolates had three extra putative N-glycosylation sites (two sites in the signal peptide region and one site in the F1 region) except for two strains of Th12 and Ac96I (two sites in signal peptide region) adding to four putative N-glycosylation sites that were conserved among all Asian isolates and Onderstepoort strain. In addition to this difference in N-glycosylation sites, the signal peptide region had a great diversity between Asia 1 and Asia 2 isolates. Also, characteristic amino acids were detected for some strains. Conclusion Asia 2 isolates were distinguished from other CDV lineages by the extra 27 nucleotide sequence. The signal peptide region of F gene gives a remarkable differentiation between Asia 1 and Asia 2 isolates. Strains Th12 and Ac96I were differentiated from other Asia 1 strains by the F protein glycosylation sites.

Abstract
Canine distemper (CD) is a highly contagious disease with a worldwide distribution. Genetic diversity in genes encoding the haemagglutinin (H) and fusion (F) virus envelope proteins have been implicated in the increasing incidence of CD. Unlike the H gene, little is known about the genetic variability of the F gene in this virus. In the present study sequence analysis of the complete coding region of the F protein from CD virus isolates from Taiwan were carried out. Phylogenetic analysis demonstrated that the majority of isolates were similar to those found in neighbouring China and Japan, but were genetically distinct from vaccine strains. Remarkable variations were found scattered throughout the pre-peptide region (residues 1-135). The sequence identity of this region between locally sourced strains and between these strains and vaccine strains was 89% and 64 to 67%, respectively. Analysis suggested a novel strain of distant genetic lineage was present in dogs in the geographically isolated city of Hualien.

Abstract
We produced a B95a lymphoid cell line persistently infected with canine distemper virus (CDV), in which virus-specific antigens were present in nearly 100% of cells without causing cytopathic effect. The virus recovered from this cell line was able to infect fresh B95a cells persistently, indicating that a persistent CDV was established.
