What is Papovaviridae?

What is Papovaviridae?

Medical Definition of Papovaviridae : a former family of double-stranded DNA viruses that included the polyomaviruses and the papillomaviruses before they were placed in their own families.

What causes Papovaviridae?

papovavirus, any virus in the families Papillomaviridae and Polyomaviridae. Papovaviruses are responsible for a variety of abnormal growths in animals: warts (papillomas) in humans, dogs, and other animals; cervical cancer in women; tumours (polyomas) in mice; and vacuoles (open areas) in cells of monkeys.

How many Parvoviruses are there?

Another group of viruses called bidnaviruses appear to be descended from parvoviruses. Within the family, three subfamilies, 26 genera, and 126 species are recognized….

Parvoviridae
Electron micrograph of canine parvovirus
Virus classification
(unranked): Virus
Realm: Monodnaviria

How is Papovaviridae transmitted?

Transmission occurs by contact. Genital warts are sexually transmitted. Laryngeal papillomas may be due to human papillomavirus acquired during birth from a mother with genital warts.

Is Papovaviridae a DNA virus?

Papillomaviruses belong to the Papovaviridae family of DNA viruses that includes mouse polyoma and the monkey virus, SV40. The family name, ‘Papova’ is derived from the first two letters of the three principal virus groups, PApilloma, POlyoma, and simian VAcuolating virus (SV40).

What diseases are caused by Papovaviridae?

Disease: Skin warts, anogenital warts (condyloma acuminatum, cervical intraepithelial neoplasia, bowenoid papulosis), oral and laryngeal papillomas, conjunctival papillo-mas, focal epithelial hyperplasia Heck; anogenital cancer, laryngeal carcinomas, tongue carcinomas, skin carcinomas of patients with epidermodysplasia …

What is the size of poxvirus?

Poxviruses are brick-shaped (240 nm by 300 nm) and have a complex internal structure including a double-stranded DNA genome (130–260 kb) and associated enzymes. Naturally released virions have an additional outer membrane not found on infective virions extracted artificially from infected cells.

How big is a Mimivirus?

Mimivirus, a giant DNA virus (i.e. “girus”) infecting species of the genus Acanthamoeba, was first identified in 2003. With a particle size of 0.7microm in diameter, and a genome size of 1.2Mb encoding more than 900 proteins, it is the most complex virus described to date.

Which families of viruses are under Papovaviridae?

The family Papovaviridae includes two genera, Papillomavirus and Polyomavirus. Papillomaviruses are naturally tumorigenic causing papillomas (warts), which occur in many different species.

What are the subfamilies of the family Parvoviridae?

The family Parvoviridae comprises two subfamilies: the subfamily Parvovirinae, which contains viruses of vertebrates, and the subfamily Densovirinae, which contains viruses of insects and other invertebrates (that will not be discussed further).

Which is a member of the papova virus family?

SV40 is classified as a member of the Polyomavirus genus in the Papovaviridae family ( Table 1 ). The other well-studied member of the genus is polyoma virus of mice. The group also includes the human polyomaviruses, BKV and JCV, as well as isolates from other species, including hamsters, rabbits, cattle, birds and baboons.

What are the members of the Papillomaviridae family?

From Wikipedia, the free encyclopedia Papillomaviridae is a family of non- enveloped DNA viruses whose members are known as papillomaviruses.

What kind of cancer is caused by papovavirus?

The family Papovaviridae includes two genera, Papillomavirus and Polyomavirus. Papillomaviruses are naturally tumorigenic causing papillomas (warts), which occur in many different species. Only those affecting cattle, horses, and dogs are likely to require veterinary attention.
