direct contact and biting arthropods
Used for biological control in Australia

Pustular Dermatitis
ZOONOTIC - “Iris Lesion”
2nd MRSA infections
Poxviridae
Parapox-Orf Virus
Name the Virus:
Infects cattle and cats - “cowpox”
Rats are its reservoir
ZOONOTIC - Smallpox
E. Jenner used it to create smallpox vaccine
Parapoxviridae
Orthopoxvirus
What Virus is Smallpox?
Poxviridae
Orthopoxvirus - Humans
Caused the Red Plague
Variola Virus Variants Major and Minor
Name the Virus:
Infects monkeys and rats - monkeypox
Infectious via direct contact ; eating raw bush meat ; vertical transmission
ZOONOTIC
Smallpox vaccine can protect up 85%
Poxviridae
Orhtopoxvirus
Name the Family:
linaer ss DNA - Exception to the rule
Non - enveloped
Coinfects with Adenovirus and Herpesvirus
Only replicates in actively cycling cells
Parvoviridae
Name the Virus:
Infects dogs
Causes Canine Parvovirus 2
Vaccines available
Parvoviridae
Protoparvovirus
Name the Viruses:
FPV
MEV
ADV
GP and MDP
PPV
FPV - Feline Pankeukopenia Virus
causes Feline Infectious Eneteritis
MEV - Mink Enteritis Virus
causes leukopenia and enteritis
ADV - Aleutian Disease Virus
causes fatality in minks and ferrets
GP and MDP - “Goose Parvovirus” and “Muscovy Duck Parvovirus”
causes Goose Plague and Hepatitis
PPV - Porcine Parvovirus
causes reproductive failure and SMEDI
What does SMEDI stand for?
Stillbirth Mummification Embryonic death and infertility
Name the Virus:
Causes parvovirus in humans
Erythema Infectiosum
Parvoviridae
B19 Human Parvovirus
Name the Family:
linear ds DNA
Enveloped –> Budding
Tegument - protein coating that protects the virus and allows for easier replication and hiding from the host immune system
Infects almost all birds, mammals and humans
Laten Infections - but NOT a Provirus
Neuronal cell bodies primarily affected
“species-jumping”
Herpesviridae
Name the Virus:
Causes herpes in Swine
Herpesviridae
SuHV 1 - Suid Hepres Virus
Name the Virus:
causes herpes in cows
Herpesviridae
BoHV 1 - Bovine Herpes Virus
Name the Virus:
causes herpes in birds
GaHV 1 and 2 - Gallid Herpes Virus
Name the Family:
circula ds DNA
Non-Enveloped
Desquamation
direct and sexual contact
very host and tissue specific
can be asymptomatic or cause benign tumors –> leads to malignant cancer
“onco-virus”
targets the basal membranes of epthelial layers –> papillomas
Papillomaviridiae
Name the Family:
circular ds DNA
Non-Enveloped
Infects mammals and birds
Polymoviridae
