Carnivore protoparvovirus 1

Common card · No. 318485

Carnivore protoparvovirus 1 is a species of parvovirus that infects carnivorans. It causes a highly contagious disease in both dogs and cats separately. The disease is generally divided into two major genogroups: the group of the classical feline panleukopenia virus (FPLV), and the group of the canine parvovirus type 2 (CPV-2), which appeared in the 1970s. Belonging to the family Parvoviridae, FPLV have linear, single-stranded DNA (ssDNA) genomes. This agent is one of the smallest animal viruses, barely 18 to 20 nm in diameter. Like other parvovirus genomes, it has hairpin structures at both ends of its genome: 3-genome Y-type structure and 5-terminal U-shaped structure, making it challenging to amplify the full-length genome of parvovirus despite its small size. Sequences in the genome show a high degree of nucleotide conservation in the VP2 gene after over 90 years since it has emerged; the VP2 gene codes for the capsid protein VP2, a main structural protein, which determines the major...
