Poxviruses
What virus where virion is enclosed in a lipid bilayer envelope containing virus-specific proteins
Poxvirus
Virus that contains Icosapentahedral capsid
Herpesvirus
Has a unique four layered structure?
Herpesvirus
What is the shape for herpedvirus?
Iscosapentahedral (linear, toroid)
In the structure of herpesvirus, what is the amorphous protein coat that surrounds the capsid?
Tegument
Virus that persist indefinetky in infected hosts, it can frequently reactivated in immunosuppressed host, and can cause cancer
Herpesvirus
Where Tzank Smear can be used?
Herpes virus and Shingles
Virus that use Ab assaye in serology ?
Poxvirus
Used to screen for infectious mononucleosis caused by EBV
Paul Bunnell Test
Family of hepandnaviridae and genus of orthohepadnaviridae
Sperical particle
Filamentous/tubular form
DANE particle
Hepatitis B virus
Uses Chemiluminescence for detection of this virus?
Hepatitis D and B virus
The first marker that can be detected after 1 week infection in hepatitis B?
HBV DNA
Marker that is detected in the blood stream soon after initial infection (1 week)
HBV DNA polymerase
it is not detectable in the bloodstream that only use liver cell sample
HBCAg
Detectable in the blood stream which is the reason for HBV that is actively reproducing
HBEAG
First antibody to appear around 8 weeks (4-6 months) after infection with HBV
Anti HBc IgM
Appears a few weeks after HBeAg is no longer detectable
Positive result which gives good sign and indicates a favorable prognosis
Patient is not infective
Anti HBE
Last antibody to appear in Hepatitis B?
Anti HBS
Hepatitis B antigen that is produced in larg quantities
HBSAG
Hepatitis B antigen that is produced in large quantities
1-6 weeks infection
HBSAG
This virus use to induce host cell to enter the S phase of the cell cycle
Consist of 11 virion protein
Adenopvirus
Contains Hexon and penton capsomers
Adenovirus
