III - A. Virology | 9. Adeno- and Poxviruses Flashcards
I. Adenoviruses
1. What are the genetic material and morphology of Adenoviruses?
- Double stranded DNA viruses
- Icosahedral shape
- (Surface: fibers: antigens, binding to cell, toxic effect)
- Non envelope – better survival in environment, outside human body
I. Adenoviruses
2. How does Adenoviruses spread?
I. Adenoviruses
3. What are the diseases caused by Adenoviruses?
- Respiratory infections
- Acute pharyngitis
- Pharyngoconjunctival fever
- Pneumonia - Other infections
- Gastroenteritis
- Conjuntivitis
I. Adenoviruses
4A. What are the respiratory infections caused by Adenoviruses?
- Acute pharyngitis
- Pharyngoconjunctival fever
- Pneumonia
I. Adenoviruses
4B. What are the features of acute pharyngitis?
- Frequent cause of acute infection of the throat
- Pain, fever, muscle ache, coughing
I. Adenoviruses
4C. What are the features of Pharyngoconjunctival fever?
- Mostly in children, small epidemics are possible
- Pharyngitis with conjunctivitis – red, watery eye and throat pain
I. Adenoviruses
4D. What are the features of pneumonia?
- Viral pneumonia may develop as complication of upper respiratory tract infection
- May cause pertussis-like symptoms
I. Adenoviruses
5A. What are other infections caused by Adenoviruses (not respiratory infections)?
- Gastroenteritis
- Conjunctivitis
I. Adenoviruses
5B. What are the features of gastroenteritis caused by Adenoviruses?
- Vomiting, watery diarrhea – frequent cause
- Epidemics in communities of children
- Risk: dehydration – replacement of lost fluids, orally or in IV form
I. Adenoviruses
5C. What are the features of conjunctivitis caused by Adenoviruses?
- Red eye, watery discharge, itching, photophobia
- Small epidemics
I. Adenoviruses
6. What are the diagnosis for adenovirus infections?
- Usually based on clinical findings, lab diagnostics rarely
- PCR, serology
I. Adenoviruses
7. What is the treatment for adenoviruses infections?
not available, usually self-limiting
I. Adenoviruses
8. What is the vaccination for adenoviruses infections?
VACCINATION is not available to prevent adenovirus infections
=> BUT adenoviruses are used in VACCINATION AGAINST OTHER VIRUSES!
I. Adenoviruses
9. What is the application of adenoviruses in medical treatment?
- Adenoviruses are used in VACCINATION AGAINST OTHER VIRUSES!
- adenoviruses of animals with limited infectivity in humans are used as vectors to deliver
nucleic acid encoding antigens of other viruses to host cells - Eg. SARS-CoV2 vaccines: Sputnik and AstraZeneca
