Globuloviridae

In today's world, Globuloviridae has become a topic of great importance and interest to a wide spectrum of society. From its impact on the economy, culture, politics and daily life, to its influence on health and the environment, Globuloviridae has achieved unmatched relevance today. Over the years, the study and analysis of Globuloviridae has evolved, allowing a greater understanding of its implications and consequences. In this article, we will explore in depth the different facets of Globuloviridae, analyzing its effects and challenges in the contemporary world.

Globuloviridae is a family of hyperthermophilic archaeal viruses. Crenarchaea of the genera Pyrobaculum and Thermoproteus (both in Thermoproteaceae) serve as natural hosts. There are four species in this family, assigned to a single genus, Alphaglobulovirus.

Taxonomy

The family contains one genus which contains four species:

Structure

Virions in the Globuloviridae are spherical and enveloped. The diameter is around 100 nm.

Genomes are linear dsDNA and non-segmented, around 20–30kb in length.

Genus Structure Symmetry Capsid Genomic arrangement Genomic segmentation
Alphaglobulovirus Spherical Enveloped Linear Monopartite

Life cycle

Viral replication is cytoplasmic. DNA-templated transcription is the method of transcription. Pyrobaculum and Thermoproteus archaea serve as the natural host. Transmission routes are passive diffusion.
