FMD / Vesiciular Stomatitis+Bovine Ephemeral Fever / SVD+VES Flashcards
Taxonomy
FMD virus- Aphthovirus genus - Picornaviridae
Indiana vesiculovirus - Vesiculovirus Genus - Rhabdoviridae
Ephemeral Fever Virus- Ephemerovirus genus - Rhabdoviridae
Swine Vesicular Disease - Enterovirus genus - Picornaviridae (indistinguishable FMD)
Vesicular Exanthema of Swine - Vesivirus genus - Caliciviridae (Atypical FMD)
Vesicle info
FMD (severe in goat and bovine) tattered edge-recover after immune response
SVD ( rupture in 2 days)
VES (heal fast)
VS (turn to ulcers in 1-2 days - Self limiting healing in 10-14 days)
FMD is a chronic disease
F
FMD spreads slowly within the herd
F-highly contagious spreads rapidly with any discharge
FMD virus is shed by semen
T
Dogs are susceptible to FMD
T
Foot and mouth disease is serologically uniform
F-7 serotypes according to location
Foot and mouth disease virus is uniform, there are no serotype or subtypes of it
F
Because of the high variability of FMD virus cross protection cannot be observed even within the serotype
T
Within the FMD serotypes, subtypes can be differentiated
T 30+
The sample from the FMD suspected animal should be submitted to lab cooled but not frozen
T
FMD ulcers are usually sharp edged and regular round shaped
F-tattered (torn poor edged)
The foot and mouth disease is classified into 7 serotypes
T
The primary replication site for FMD is the tongue mucosa
F-tonsils pharyngeal laryngeal mucosa
FMD can be transmitted by frozen meat
T-months alive also by milk powder
The peracut form of FMD causes severe haemorrhages and death by shock
F- en eshei forms nmz
The chronic form of FMD means arthritis
F- no forms no arthritis just lameness- loss of keratin layer in swine feet
FMD is transmitted by insect vectors
F-per os aerogenous and discharge
Vesicles of FMD can fully recover after immune response
T
FMD causes the loss of hoof in swine
T
Foot and mouth disease can be carried for long time in the hoof tissue
T-and tonsils
The SAT-1,2 and 3 serotypes of FMD virus are present in Africa and Arabia
T
In humid cold environment, the FMD virus can retain its infectivity for weeks
T
Even the vaccinated animals can carry and shed the FMD virus
