Abstract
Canine parvovirus (CPV) is a highly contagious
viral disease and the most significant intestinal pathogens affecting dogs as
well as puppies, making these infections a real danger on dog population
worldwide. Therefore, this study was to elucidate and detect canine parvovirus
strains circulating in Palestine. This was achieved by molecular analyzing of
VP2 gene by polymerase chain reaction (PCR). In the current study, a total
number of 25 dogs suffered from severe watery bloody diarrhea, vomiting and
lethargy were examined serologically to confirm parvovirus antigens. Complete
Blood count (CBC) was also involved to assess the effects of the virus on the
hematological parameters of each dog. The PCR positive samples were evaluated by
Sanger’s sequencing method to characterize the virus and to obtain the essential
information about the genotypes and nucleotide polymorphisms of CPV strains
circulating in Palestine. The partial nucleotide sequences of VP2 gene were
compared with reference VP2 gene sequences of CPV recorded in GenBank database.
The phylogenetic analysis revealed that 24/25 (96%) of the sequences belonged to
serotype CPV-2c and 1/25 (4%) belonged to
serotype CPV-2b. The current obtained
sequences were registered at the GenBank database under the following accession
numbers: OQ924950- OQ924974. To our knowledge, this report is considered the first one to
investigate the molecular characterization of CPV-2in Palestine. This finding could be useful for
commercial vaccine companies to select the suitable strains of CPV that include
the prevalent antigenic types of the field virus, to enhance the immunity
against CPV in dogs.
