during mating
contact with infected wildlife
wind-borne transmission
indirect contact- via fomites

hoof sloughing
snout vesicles
oral lesions
Do sheep/ goats get FMDV clinical signs
they may get some but they are very mild if they do

eye/nasal discharge
drooling
pyrexia
swelling of the mouth

haemorrhages
inflammation of the skin of the coronary band
respiratory problems
fever
lethargy
List the clinical signs of blue tongue virus in cattle
nasal discharge
swelling of the head/neck

swelling and ulceration of the mouth
swollen teats
lethargy
hypersalivation
pyrexia
List the clinical signs of rabies
hypersalivation
behavioural change
muzzle tremors
vocalisation
aggression
hyperaesthesia
pharyngeal paralysis
why can IBR cause hypersalivation
due to the ruminal stasis
List the 3 treatment/ control options for FMDV
eradication programmes
vaccinate to kill
vaccinate to live

pyrexia
inappetance
corneal opacity
nasal discharge
crusting of the muzzle
enlarged lymph nodes
exudative dermatitis around the udder

what bacteria causes wooden tongue
Actinobacillus lignieresii
Describe how bovine papilloma virus is spread
abrasions
direct contact
+/- flies
Describe how wooden tongue presents
pain
stomatitis
glossitis
fibrous tissue
cellulitis
swollen tongue
submandibular swelling
rapid loss of BCS
Describe how you treat wooden tongue
antibiotics gram -ve (penicillin and streptomycin) facultative anaerobe
iodides - oral potassium iodide
NSAIDs
What bacteria causes lumpy jaw
Actinomyces bovis
Describe how lumpy jaw presents
hard
immobile lesions
chronic infectious disease
painful
+/- pyrexia
Describe how lumpy jaw occurs
mucosal damage allows commensals of the oral cavity to invade the bony structures via the lymphatics
Describe how lumpy jaw is treated
antibiotics- gram +ve anaerobe - procaine benzylpenicillin
sodium iodide
NSAIDs

Necrotic laryngitis- laryngeal form- ulceration of the larynx
Describe how calf diptheria occurs
mucosal injury leads to GI/URT commensal infecting the mouth

Is dental disease common in ruminants
No

periodontal disease
Describe how to treat calf diptheria
3-5 day course of Abs (penicillin, tetracycline, TMPS)
NSAIDs
