What is the etiology of Feline Panleuko-penia Virus?

It is well known that the abbreviation of Feline Panleuko-penia Virus is FPV, and FPV can also be the abbreviation of Feline Parvovirus. Is Feline Panleuko-Penia Virus the same as Feline Parvovirus? What is the connection between feline parvovirus and canine parvovirus? Who is the real pathogen that causes Feline Panleuko-penia Virus?

Feline Parvovirus and Canine Parvovirus

Both feline parvovirus and canine parvovirus can infect cats and cause disease. 

Feline parvovirus can infect domestic cats, wild cats (felis) and some wild canids (canis), such as raccoons and foxes. Canine parvovirus is derived from feline parvovirus through a series of mutations, and its subtypes CPV-2a, CPV-2b, and CPV-2c are all pathogenic to cats. About 90%-95% of feline distemper cases are caused by feline parvovirus infection, and <10% of feline distemper cases are caused by canine parvovirus infection. Mixed infection can occur with feline parvovirus and canine parvovirus, as can different subtypes of canine parvovirus

Virological classification of Feline Panleuko-penia Virus pathogens

Feline panleukopenia virus belongs to the family Parvoviridae, the subfamily Parvoviridae, the genus Proparovirus, and the carnivore Proparvovirus type 1.

In the chart, we can find that in the virological classification, carnivore pro-parvovirus. Virus 1 has only one subclass, that is, feline panleukopenia, virus, and sometimes we can even consider carnivore pro-parvovirus

Type 1 = Feline panleukopenia virus. According to the genotype, carnivore pro-parvovirus type 1 is divided into feline parvovirus and canine parvovirus. Feline panleukopenia virus category includes a variety of canine parvovirus (CPV-2, CPV-2a, CPV-2b, CPV-2c, etc.) and blue fox parvovirus Tai'an strain, mink enteritis virus, raccoon parvovirus, etc. A variety of feline parvoviruses that mutate and infect other species of parvovirus.

At the same time, we found that Feline Parvovirus was not mentioned in the virological classification.

Summarize

The pathogen that causes feline distemper is called feline panleukopenia virus, also known as feline distemper virus. In a broad sense, it is equivalent to the carnivore original parvovirus type 1, including feline parvovirus and a variety of parvoviruses derived from it.

In a narrow sense, at least the feline parvovirus and canine parvovirus subtypes (CPV-2a, CPV-2b, CPV-2c) capable of infecting cats and causing clinical and subclinical symptoms are covered
