| Phylogenetic analysis of canine parvoviruses
from Turkey |
| Canine parvovirus (CPV) type 2 is the causative agent of acute hemorrhagic enteritis and high mortality in
the affected dogs. Numerous studies have been done to understand the origin of the virus and to exhibit new
variants and circulating strains. This report describes the detection and genomic characterization of CPV
strains from indoor and outdoor dogs in Ankara, Turkey. Samples were sent to our laboratory due to clinical
symptoms in puppies. We tested blood and swab samples to determine the presence of canine parvovirus (CPV)
in three puppies and two adult dogs by reverse transcription-polymerase chain reaction (RT-PCR) using VP2
(capsid protein) region primers of canine parvoviruses. Following that, to provide molecular characterization
data Maximum Likelihood (ML) method was used for phylogenetic analyses. Constructed phylogenetic trees
from the aligned nucleotide sequences revealed that our CPV strains demonstrated high genetic similarities,
with 100% identity match on nucleotide alignments with each other and classified in CPV-2b genotypes.They
have placed on a monophyletic clade as a sister branch with CPV VAC S quantum with 98.9% nucleotide
homology. Our findings suggest that CPV-2b is actual and frequently seen variant in Turkey and shows high
similarities with other CPV variants and a bit less with FPVs in Turkey and around the world. CPV causes
high mortality and morbidity in dogs and to develop effective vaccines for protection of dogs in Turkey where
there are few numbers of studies that have been done, field strains should be isolated and characterised. |
