Chapter 25 Flashcards
What is Orthomyxoviridae?
An enveloped RNA virus
Etiologic agent/infection caused by Orthomyxoviridae?
Influenza A and B
Transmission of orthomyxoviridae?
Respiratory
How many segments in Orthomyxoviridae?
8 segments
Notes about Orthomyxoviridae?
Influenza A causes pandemics. B makes you sick too, but not as bad as A.
Glycoproteins:
Hemagglutinin - H, viral spike for attachment
Neuraminidase - N, allows virus to be released
Drift - minor change
Shift - major change
Can mutate due to mixing segments w/ other animal flus
