viruses Flashcards
Orthomyxoviridae vaccination
ABC
RNA Virus so technically should Replicate in the cytoplasm I thought this one can be both a and B are the ones that are most relevant to us and he is the only zooinose ike swine and birds
negative sense
To glycoproteins contained within the envelope haemagglutinating 15 subtypes and neuraminisade 9 subtypes
seasonal trivalent
live -sprayed into the nose
killed-
treatment; amantidine and rimantadine
Main difference between orthomyxovirus is and paramyxovirus is
Oiruses can replicate in either the cytoplasm or the nucleus where is para always replicate in the cytoplasm
Also have segmented or any Gino which allows it to change its antigens where is para have a nonsegmented or any Ginos
ortho is smaller and doesnt have giant cell formaton
para have f spikes Enabling cell to cell fusion and that forms multinucleate giant cells
Paramyxoviridae also replicate in the upper respiratory tract and can produce influenza-like illness, but
they also produce a PARAde of distinctly different diseases. The paramyxoviridae include parainfluenza
virus,
Three important things to remember about herpesvirdae
- They can develop a latenet l state the
- members in the sub family alpha have cytopathic affect on cells which become multinucleated giant Synctial cells with intranuclear inclusion bodies and these viruses are 3. held at bay by the cell mediated in the system
Which are the alpha subtypes of herpes Verdy
HS1
HS2
VCV
DIFFERNECE BETWEEN HS1 AND HS2
both are antigenetically sisitnct
what does EBV CAUSE and what cells does it infect
pharygitis
enlarged lymph nodes
splenomegaly
epithelial cells (pharynx), t and b cells
how is EBV spread And how can we diagnose it
through saliva, kissing disease In the blood you will see a typical lymphocytes which have an enlarged nucleus
Which other diseases also cause mononucleosis HIV CMV hepatitis
HIV CMV hepatitis
poxivirdae and what does it cause
dna virus breaks the rule as replicates in the cytoplasm very complex like herpes it has an evelope does not have an isocohedral shape
causes chicekn pox (variola)
types of capsids
helical and isocahedral
virus envelope
Viruses acquire this
membrane by budding through the host cell nuclear or
cytoplasmic membrane and tearing off a piece of the
membrane as they leave
so viruses can be naked or enveloped
What type of virus is HIV
retrovirus
