Cytomegalovirus (CMV) (from cyto- 'cell' via Greek κύτος kútos- 'container' + μέγας mégas 'big, megalo-' + -virus via Latin vīrus 'poison') is a genus of viruses in the order Herpesvirales, in the family Herpesviridae, in the subfamily Betaherpesvirinae. (wikipedia.org)
Within the Herpesviridae, CMV belongs to the Betaherpesvirinae subfamily, which also includes the genera Muromegalovirus and Roseolovirus (human herpesvirus 6 and human betaherpesvirus 7). (wikipedia.org)
It is also related to other herpesviruses within the Alphaherpesvirinae subfamily, which includes herpes simplex viruses 1 and 2 and varicella-zoster virus, and the Gammaherpesvirinae subfamily, which includes Epstein-Barr virus and Kaposi's sarcoma-associated herpesvirus. (wikipedia.org)
Thus HR1, HR2, HR3 for human retroviruses 1, 2 and 3 is appropriate and does not prejudice the likelihood that HR1 and HR2 will end up in one genus of one subfamily whereas HR3 may end up in a different subfamily and genus. (nih.gov)
The genus Macavirus, subfamily Gammaherpesvirinae, comprises ungulate viruses that infect domestic and wild ruminants and swine. (bvsalud.org)
The 11 species in this genus include human betaherpesvirus 5 (HCMV, human cytomegalovirus, HHV-5), which is the species that infects humans. (wikipedia.org)
This is not a bad idea particularly because many viruses have a preferred host even if they do cross species. (nih.gov)
Classification1
The classification of viruses is complex and based on many factors, including type and structure of the nucleoid and capsid, the presence of an envelope, the replication cycle, and the host range. (lecturio.com)
Genome3
Most viruses, however, will have a genome formed by either DNA or RNA. (lecturio.com)
Viruses with a DNA genome can be further characterized as single or double stranded. (lecturio.com)
Some enveloped viruses translate DNA into RNA before incorporating into the genome of the host cell. (lecturio.com)
Human6
Human CMV is the most studied of all cytomegaloviruses. (wikipedia.org)
The most studied is Human cytomegalovirus (HCMV), which is also known as Human betaherpesvirus 5 (HHV-5). (wikipedia.org)
Herpesviruses have some of the largest genomes among human viruses, often encoding hundreds of proteins. (wikipedia.org)
It is thus longer than all other human herpesviruses and one of the longest genomes of all human viruses in general. (wikipedia.org)
BK virus (BKV) and JC virus (JCV) are small, nonenveloped, double-stranded DNA viruses belonging to the Polyomaviridae family, which are ubiquitous in the human population. (lecturio.com)
Human polyomavirus 1: BK virus Virus Viruses are infectious, obligate intracellular parasites composed of a nucleic acid core surrounded by a protein capsid. (lecturio.com)
Cell2
The virus exits the host cell by nuclear egress, and budding. (wikipedia.org)
Enveloped" viruses are covered by a thin coat of cell membrane, which is usually taken from the host cell. (lecturio.com)
Disease1
In these instances the viruses were named after Epstein and Barr, a disease, and cytopathology. (nih.gov)
