Biology Notes on Retroviridae | Microbiology

The below mentioned article provides notes on retroviridae. The family Retroviridae falls under the Group VI (ssRNA-reverse transcribing viruses). The virions are enveloped, helical or isometric having two linear (+) sense ssRNA, reverse transcriptase and integrase. Examples are MLV [Murine leukemia virus and related virus e.g. Spumavirus (human foamy virus)], Lentivirus (human immunodeficiency virus or HIV), Visna virus, Deltaretrovints, Alpharetrovims. [...]

Replication of Picomavirus | Microbiology

In this article we will discuss about the replication of picomavirus. The virion RNA is infectious and serves as both the genome and viral messenger RNA. The internal ribosome entry site (IRES) allows direct translation of the polyprotein. The polyprotein is initially processed by the viral protease(s) into various precursor and mature proteins to yield the structural proteins, replicase, VPg, [...]

Replication of Influenza Viruses | Microbiology

In this article we will discuss about the replication of influenza viruses. Influenza virus is transmitted from infected mammals through the air by sneezing. Sneezing creates aerosols which consist of several virus particles. Besides, influenza is also transmitted by saliva, nasal secretions, blood and faeces. Moreover, it also spreads through droppings of infected birds. These bodily fluids or contaminated surfaces [...]
