Study Notes
Coronavirus Structure and Replication
- The coronavirus has a crown-like shape, with glycoproteins on the outer layer appearing as club-shaped projections, giving a halo-like appearance on electron microscopy.
- The virus is encapsulated, with a king-like structure wearing a robe, representing the nucleus surrounded by a protective layer.
Replication and Evolution
- Replication of coronavirus generates individual mRNA's for individual viral proteins, increasing the capacity for genetic drift (evolution/resistance).
- The virus replicates in the cytoplasm, with the king (nucleus) outside the castle (cytoplasm).
Infection and Transmission
- Sneezing and blowing one's nose can cause the common cold.
- Coronavirus infections are usually limited to the upper respiratory tract because the optimum temperature for growth is between 33°C and 35°C.
SARS and Respiratory Tract
- SARS is a type of coronavirus that infects the lower respiratory tract and causes acute respiratory distress.
- The king's respiratory tract design is associated with SARS and Middle East Respiratory Syndrome (MERS), as well as acute bronchitis.
- X-ray shows spontaneous pneumothorax in SARS cases.
