Micro Vii - P.160-161

Front 1

nematodes (roundworms)
which bugs you ingest (3 of them)
which bugs infect cutanously (3 of them)

both have mnemonics

Back 1

Ingested - EAT:
- Enterobius
- Ascaris
- Trichinella

Cutaneous - get from feet in SANd
- Strongloides
- Ancylostoma
- Necator

Front 2

Parasite hints - name the parasite:
1. brain cysts, seizures
2. liver cysts
3. B12 deficiency
4. Biliary tract disease
5. hemoptysis
6. portal hypertension
7. hematuria, bladder cancer
8. microcytic anemia
9. perianal pruritis

Back 2

1. taenia solidum (cysticercosis)
2. echinococcus granulosus
3. diphyllobothrium latum
4. Clonorchis sinesis (oriental liver fluke - biliary/pigment gallstones composed of calcium bilirubinate)
5. Paragonimus westermani
6. Schistosoma mansoni
7. schistosoma haematobium
8. Ancylostoma, Necator
9. Enterobius

Front 3

DNA viral genomes - fill in or choose right word
1. All DNA viruses except _________ are (single/double) stranded.
2. All are (linear/circular) except ______ _______ and _______ which are (linear/circular)

Back 3

1. all are DOUBLE STRANDED except Parvoviridae (single)
2. all are LINEAR except papilloma, polyoma and hepanavirus

Front 4

All RNA viruses except _______ are (singe/double) stranded RNA

Back 4

1. SINGLE STRANDED except Reoviridae

Front 5

Naked viral genome infectivity
- describe

Back 5

- purified nucleic acids of most dsDNA (except poxvirus and HBV) and +strand ssRNA (=mRNA) are infectious
- naked nucleic acids of -strand ssRNA and ds viruses are not infectious - they require enzymes contained in the complete virion

Front 6

naked (nonenveloped viruses)
-mnemonic!-

Back 6

NAKED people may need CPR or PAPP smear
- Calcicivirus
- Picornavirus
- Reovirus

- Parvovirus
- Adenovirus
- Papilloma
- Polyoma

Enveloped viruses acquire their evelopes from plasma membrane when they exit cell
- exceptions: herpesviruses - acquire their envelopes from nuclear membrane

- ETHER and other ORGANIC SOLVENTS dissolve the lipid bilayer that makes up the outer viral envelope
- loss of infectivity after ether exposure is a characteristic feature of enveloped viruses

Front 7

Virus ploidy

Back 7

All viruses are HAPLOID (1 copy of DNA or RNA) except RETROVIRUSES! - which have 2 identical ssRNA molecules (=diploid)

Front 8

viral replication location:
- DNA viruses
- RNA viruses

Back 8

- DNA viruses all replicate in the NUCLEUS (except poxvirus)
- RNA viruses all replcate in the cytoplasm (except influenza virus and retrovirus)

Front 9

DNA enveloped viruses

Back 9

Herpesviruses (HSV1 and 2, VZV, CMV, EBV)
HBV
smallpoxvirus

Front 10

DNA nucleocapsid viruses

Back 10

Adenovirus
papillomaviruses
parvovirusRNA

Front 11

RNA enveloped viruses

Back 11

influenza virus
parainfluenza virus
RSV
measles virus
mumps virus
rubella virus
rabies virus
HTLV
HIV

Front 12

RNA nucleocapsid viruses

Back 12

Enteroviruses (poliovirus, coxsackievirus, echovirus, HAV)
rhinovirus - COMMOM COLD!!!
reovirus (rotavirus)

Front 13

general rules about DNA viruses

Back 13

1. HHAPPPPy
Hepadna
Herpes
Adeno
Pox
Parvo
Papilloma
Polyoma

Are ds - EXCEPT parvo (ss)

Are linear - EXCEPT papilloma and polyoma (circular, supercoiled) and hepadna (circular, incomplete)

Are icosahedral - EXCEPT pox (complex)

Replicate in the nucleus - EXCEPT pox - carries its own DNA-dependent RNA polymerase)
