Adenovirus
Adenovirus is first isolated from cultures of?
Adenoids and tonsils (1950s)
Site of latency of Adenovirus
Replication in oropharynx
Adenovirus serotypes 40 and 41 causes
Gastroenteritis in infants and children
Other adenovirus serotypes causes
Conjunctivitis and Keratitis
MOT of Adenovirus
Respiratory, fecal-oral, and direct contact (eye)
Diseases associated with Adenovirus (7)
Pharyngitis, pharyngoconjunctival fever, keratoconjunctivitis, pneumonia, hemorrhagic cystitis, disseminated disease, and gastroenteritis in children
What serotypes of Adenovirus is associated with respiratory epidemic in military recruits?
Serotypes 4 and 7
Pleomorphic, icosahedral enveloped viruses containing circular, partially double-stranded DNA
Hepadnavirus
Virion is called as
Dane particle
The surface antigen in hepadnavirus is called
Australia antigen
MOT of Hepadnavirus
Percutaneous exposure to blood, perinatal or sexual contact, direct contact
Site of Latency of Hepadnavirus
Liver
The most reliable marker for identifying HBV infection.
Hepatitis B surface antigen (HBsAg)
This antigen indicates the patient is in convalescence or previously vaccinated and has developed immunity.
Anti-HBsAg (antibody to surface antigen)
Presence of this indicates high infectivity and a chronic carrier state.
HBeAg (hepatitis B e antigen)
The best indication of active viral replication and a high state of infectivity
HBV DNA in the serum
