VIRUSES OF THE PARVOVIRIDAE FAMILY: MOLECULAR GENETICAL ASPECTS OF REPRODUCTION AND MEDICAL IMPORTANCE
Abstract
Discovery of new parvoviruses led to taxonomical structure and the nomenclature of the Parvoviridae family reevaluation. There are two subfamilies: Densovirinae and Parvovirinae. Densovirinae subfamily consists of viruses of arthropoda. The Parvovirinae subfamily includes eight genuses of vertebrate animals viruses. In this review parvoviruses which are of interest to practical health care will be considered. Data on molecular and biological and virological characteristics of viruses, epidemiological and clinical features of the infections caused by these viruses are submitted. Parvoviruses whichare interesting for human health care belong to five genuses: Bocaparvovirus, Dependoparvovirus, Erythroparvovirus, Protoparvovirus and Tetraparvovirus. The most known person pathogenic parvovirus is the Primate erythroparvovirus 1 virus which was earlier called by Human parvovirus B19. It was discovered in 1975. It relates to the Erythroparvovirus genus. In this review the main attention is paid to less known viruses of this family. In viral lower respiratory tract infections structure the leading place is taken by Human Bocavirus — Primate bocaparvovirus 1 and Primate bocaparvovirus 2 relating to the Bocaparvovirus genus. In 2005, the virus of human, Primate tetraparvovirus 1, was discovered which belongs to the genus Tetraparvovirus. Clinically acute form of a tetraparvoviral infection is a top and lower respiratory tract and an alimentary tract disease. The virus possesses teratogenic action. Protoparvovirus genus representatives cause an alimentary tract disease also. Two species, pathogenic for the person are described. Bufavirus (Primate protoparvovirus 1) was found in 2012. Tuzavirus (Primate protoparvovirus 2, Tusavirus 1) was highlighted in 2014. Rodent protoparvovirus 1 which consist of rodents viruses is very interesting species for therapy of the human. Viruses of this species are capable to infect a wide range of human cancer cells, have the expressed carcinolytic properties and are perspective for treatment of person with a cancer. The human virus of the Dependoparvovirus genus called Human adeno-associated virus was discovered in 1965 in the drugs of an adenovirus. This virus isn’t associated with any disease however the virus can be located in a certain locus of the 19th human chromosome and is a perspective candidate like a vector for the treatment of genetic diseases.
