Flashcards
Intranuclear Inclusion
Intranuclear Inclusion
The presence of densely packed materials within the nucleus of an infected cell, characteristic of adenovirus infection.
Adenovirus Transmission
Adenovirus Transmission
Adenovirus can be spread through direct contact with infected individuals or contaminated surfaces.
Who is at risk for adenovirus?
Who is at risk for adenovirus?
Young children, military personnel in close quarters, and people in public swimming areas are more susceptible to adenovirus infections due to close contact and potential exposure.

Study Notes
Adenovirus Characteristics
- Adenovirus is a DNA virus
- It affects the adenoids and oropharynx
Transmission
- Adenovirus is transmitted via respiratory droplets
- Fecal-oral transmission also occurs
- Direct contact is another mode of transmission
High-Risk Groups
- Little children are at high risk of adenovirus infection
- Military recruits are also at high risk
- Public pools are a common location for adenovirus transmission
Disease Processes
- Adenovirus causes tonsillitis
- It can also cause hemorrhagic cystitis
- Viral conjunctivitis (pink eye) is another disease process caused by adenovirus
Vaccine
- Military recruits typically receive a live vaccine for adenovirus prevention
Adenovirus Structure and Function
- Penton fibers of adenovirus are toxic
- Receptor binding is a key function of adenovirus
Permissive Cells
- Epithelial cells lining the oropharynx, respiratory, and enteric organs are permissive cells for adenovirus
Hallmark of Adenovirus
- Dense, central intranuclear inclusion (consisting of viral DNA and protein) within an infected cell is the hallmark of adenovirus
Additional Diseases Caused
- Adenovirus can cause acute viral gastroenteritis
