1

DNA viruses

Hepadnavirus, Herpesvirus, Adenovirus, Parvovirus, Papovavirus, Poxvirus

2

Hepadnaviruses

HBV
- acute or chronic hepatitis
- vaccine available
- has reverse transcriptase but NOT retrovirus

3

Herpesviruses

-HSV-1: oral (some genital) lesions, keratoconjunctivitis
-HSV-2: genital (some oral) lesions
-- VZV: chickenpox, zoster, shingles
-EBV: mononucleosis, Burkitt's lymphoma
-CMV: infection in immunocompromised, esp transplant recipients; congenital defects
-HHV-6: roseola (exanthem subitum)
-HHV-8: Kaposi's sarcoma-associated herpesvirus (KSHV)

4

Adenovirus diseases

-febrile pharyngitis -- sore through
- pneumonia
- conjunctivitis

5

Parvovirus disease

B19 virus -- aplastic crisis in sickle cell disease, "slapped cheeks" rash-- erythema infectiosum (fifth disease), hydrops fetalis

6

Papovaviruses

-HPV- warts, CIN, vervical cancer
- JC- progressive multifocal leukoencephalopathy (PML) in HIV

7

Poxviruses

-Smallpox, although eradicated, could be used in germ warfare
-Vaccinia- cowpox (milkmaid's blisters)
- Molluscum contagiosum

8

RNA viruses

Picomavirus, Calciviruses, Reoviruses, Flaviviruses, Togaviruses, Retroviruses, Coronaviruses, Orthomyxoviruses, Paramyxoviruses, Rhabdoviruses, Filoviruses, Arenaviruses, Bunyaviruses, Deltavirus

9

Hepadnavirus

Envelope
DS-partial circular
- HBV-- acute/chronic hep,
- vaccine
- has reverse transcriptase but not retrovirus

10

Herpesvirus

enveloped, DS-linear
- HSV1, HSV2, VZV, EBC, CMV, HHV-6, HHV-8

11

Adenovirus

no envelope, DS - linear
- febrile pharyngitis, pneumonia, conjunctivitis (pink eye)

12

Parvovirus

No envelope, SS-linear (-)
- smallest DNA virus
- B19 virus-- aplastic crises in sickle cell disease, "slapped cheecks" rash-erythema infectiosum (fifths disease), hydrops fetalis

13

Papovavirus

No Envelope, DS-circular
- HPV - warts, CIN, nervical cancer
-JC- progressive multifocal leukoencephalopathy (PML) in HIV

14

Poxvirus

envelope, DS-linear
largest DNA virus
- smallpox, vaccinia, molluscum contagiosum

15

which RNA viruses have envelope

ALL except Picomaviruses, calciviruses, reoviruses
