Virus Species & Their Families

Tiny (+) strand RNA viruses; Rhinovirus in the other picornovirus we talked about

these guys mutate like crazy. (-) strand RNA viruses

(-) strand RNA viruses

cause the common cold, and SARS

(+) strand RNA virus family

Cause the common cold; Picornoviridae are (+) strand RNA viruses

also cause small pox/variola and monkey pox. Large DNA viruses

Large DNA viruses; alpha causes oral & genital herpes, and chickenpox. Beta causes cytomegalovirus. Gamma includes EBV and the Kaposi Sarcoma virus.

Filoviruses cause Ebola and Marburg diseases (marburg is an ebola-like disease, first described in Marburg, Germany in the '60s). As viruses go, filoviruses are pretty bad news.

require co-infection w/ adenovirus; can't produce viral particles on their own. Small DNA viruses

Hantavirus is classified as a Bunyavirus and a (-) strand RNA virus. Bunyaviruses are a family of viruses that have a segmented genome consisting of three RNA strands, one of which is negative-sense. Hantaviruses are part of this family and also have a negative-sense RNA genome. This means that the genetic material of Hantavirus is complementary to the mRNA and needs to be transcribed into a positive-sense RNA before it can be translated into proteins. Therefore, the correct answers are Bunyavirus and (-) strand RNA virus.

These guys actually shed viral particles from the farther up, more differentiated layer of epithelial tissue.

Adenoviruses are responsible for causing the common cold, which is a viral infection that affects the upper respiratory system. Additionally, adenoviruses are classified as large DNA viruses, as they have a double-stranded DNA genome. These characteristics make adenoviruses distinct and enable them to replicate and cause infections in humans.
