Foot-and-Mouth Disease (FMD) Flashcards
is a highly contagious viral disease of many wild and domestic cloven-footed mammals and many other animals
Foot-and-mouth disease (FMD)
Foot-and-mouth disease (FMD) is a highly contagious viral disease of what type of animals?
wild and domestic cloven-footed mammals and many other animals
In swine, the disease is characterized by vesicles on the feet, snout and in the mouth.
Foot-and-Mouth Disease (FMD)
In this animal, FMD is characterized by vesicles on the feet, snout and in the mouth.
swine
In swine, FMD is characterized by?
vesicles on the feet, snout and in the mouth
Animals susceptible to FMD
wild and domestic cloven-footed mammals and many other animals
animals resistant to FMD
Horses
In countries where FMD occurs endemically and pigs are present in large numbers, these animals are frequently infected.
swine
age susceptible to FMD
All age groups
causative agent of FMD
Aphthovirus of the family Picornaviridae
how many serotypes are there in FMD?
7
ENUMERATE
seven immunologically distinct types of FMD virus:
A, O, C, South African Territory (SAT) 1, 2, 3 and Asian 1
how many subtypes of FMD virus have been identified?
60 subtypes
reasons why it is impossible to prepare a single vaccine that protects satisfactorily against all strains
✔ antigenic variation of the virus
✔ limited cross protection among strains
ENUMERATE
Effective disinfectants of FMD virus
1) sodium hydroxide
2) acetic acid
3) sodium carbonate
4) Virkon® (Durvet)
FMD transmission occurs through?
✔ respiratory aerosols
✔ direct or indirect contact with infected animals
this type of transmission of FMD virus over distances as great as 30 miles is believed to occur under certain weather conditions
Aerosol transmission
exceptional disseminators of FMD virus
Infected swine
a virus capable of infecting a multitude of cloven-hoofed animal species including both ruminants and suids
FMD virus, an Aphthovirus of the Picornaviridae family
For some virus subtypes, they are able to produce aerosols many times greater in virus concentration than those produced by cattle or sheep
