Pseudocowpox spreads slowly on a farm
T
Pseudocowpox virus usually causes nodules on face of infected cats
F
Reinfection can happen in the case of pseudocowpox virus
T
weak antigens because parapox genus
Pseudocowpox causes a pockmark after infection

Pseudocowpox is a zoonotic agent
T
People are susceptible to pseudocowpox infection
T
Pseudocowpox infections result a long lasting immunity
F
In cattle, Pseudo-cowpox lesions are usually seen on the teats
T
Pseudo-cowpox can cause Pseudo-lumpy skin disease in cats
F
bovine herpes mamilitis if generalised is called pseudo lumpy skin disease
but in most causes is localised on teats and rarely spreads to genital and perineal area
In cattle Pseudopox lesions are usually mild and transient
T
to scabby mouth eshei strong crustation on udder
Recovering from Pseudo-cowpox leaves/results in lifelong immunity
F
Pseudo-cowpox virus only infects cloven-hoofed animals
F
humans as well
Pseudo-cowpox infections may be present in humans
T
