Lec 2 Flashcards
its factors are:
- causing excess salivation
- attributed to difficulty in swallowing
drooling
etiologic agent of wooden tongue/actinobacillosis
Actinobacillus lignieresii
wooden tongue antibiotics
- penicillin
- Ceftipure
what dx?
- excessive salivation
- pus, swelling, inflammation
- gram (-) anaerobe
calf diphtheria or necrotic laryngitis
etiologic agent of calf diphtheria;
common inhabitant/commensal of laryngeal area
Fusobacterium necrophorum
calf diphtheria antibiotics
- oxytetracycline
- penicillin
- not common in PH
- more common in other countries
- poisoning (lead, rhododendron, OP)
- acute photosensitization
can cause excessive salivation; under surveillance in PH
FMD (foot and moth dx)
what dx?
- 3-day fever
- insect-borne
- presenting sign: drooling
ephemeral fever
difficulty in swallowing; backward water flow
dysphagia
- causes drooling
- underrecognized condition
- welfare-related
- common in tropics
heat stress
what stage?
- increased RR
- tachypnea
- restless
- animal stands
- insignificant
Stage 1
what stage?
- animals group together
- slight drooling
- elevated RR
- drooling still not alarming/significant
Stage 2
what stage?
- alarming
- excess drooling/foaming
- increased RR
- animal stands
- restless
- differential dx: FMD, calf diphtheria
Stage 3
what stage?
- open mouth breathing
- gasping w/out sound
- can be attributed to stroke and sudden death
Stage 4
what stage?
- elevated HR w/ flank involvement
- open mouth breathing w/ protruding tongue
- almost no saliva seen
Stage 5
what stage?
- terminal/fatal stage
- labored breathing
- decreased HR
- open mouth breathing w/ protruding tongue
- head down
- slight drooling
- elevated RR
- isolation (behavior) from herd
- usually too late to revive
Stage 6
heat stress management
- provide cold compress, ice water bath, shower/sprinkler
- rare in cattle
- different from regurgitation
vomiting
what is affected in vomiting?
anything that is innervated by the vagus nerve and dorsal and ventral sac of rumen
causes of vomiting
- plant poisoning
- abomasal ulcer
- esophageal foreign body
- acute bloat/esophageal dilatation
it is a common and important presenting syndrome
AAP (acute abdominal pain)
3 main causes of AAP
- acute gut obstruction
- acute enteritis
- acute fermentative colic/bloat
7 Fs
fat
fetus
feces
food
fluid
flatus (gas)
FB
usually associated w/ fluids and gas
acute abdominal distension
it happens when the left portion of the body is distended
ruminal distension
