Study Notes
Picornavirus Family
- Picornaviruses are positive sense single-stranded RNA viruses.
- They replicate in the cytoplasm, using host cell RNA polymerase.
Characteristics
- Fecal-oral transmission is a common route for picornaviruses, except for Rhinovirus.
- Rhinovirus is associated with the common cold and is not transmitted via the fecal-oral route.
Replication
- POS Sense RNA Replication uses host transcription factors and RNA polymerase, as it is the same sense as the host cell.
- Viral RNA is transmitted into a long protein product that contains viral proteases to cleave it.
Types of Picornaviruses
- Enteroviruses (e.g., Polio, Cocksackie) are types of picornaviruses that can cause aseptic meningitis.
- Rhinovirus is a type of picornavirus that causes the common cold.
- Hepatitis A is a type of picornavirus that affects the liver.
Lab Findings and Clinical Presentation
- Aseptic meningitis is characterized by normal glucose levels, no growth on plate cultures, and elevated protein levels.
- Meningitis is often associated with picornaviruses, with enterovirus being the most common cause in children.
Other
- POS sense replication takes place during the day, while NEG sense replication takes place at night.
- RNA viruses are represented by warm red colors, while DNA viruses are represented by cold blue viruses.
- The "Statue of David" symbolizes a naked virus.
