Nasal discharge PPT Flashcards
define GPE
guttural pouch empyema
collection of pus in body cavity (GP)
not Strangles
Agents of GPE
main difference between the agents
Strep. zooepidemicus & Strep. equi
S. zoo is opportunistic
S. equi = pathologic!
highly contagious - isolate! both will look same until culture
Typical Clinical scenario with GPE
recurrent unilateral nasal discharge
waxes & wanes w/ antimicrobial & anti-inflammatory use
What can be a sequela of GPE
Chondroids
concretions of inspissated pus
Tx for GPE
Antimicrobials
-Penicillin ->+/- TMS
–#1 DOC for Strep organisms
GP flush
saline/LRS +/- acetylcysteine
Possible Sx
Causative agent of strangles
Strep equi (aka Strep equi var equi)
esp in younger horses (<6mos), weanlings, yearlings
CS of strangles
Acute onset
Fever, cough, lethargy, anorxia
High morbidity (100%)
Low mortality (2%)
can look like viral dz at first
pathogenesis of strangles
submandibular LN abscessation
- day 0-7 bacteria multiply
- day 7-14 maturation & rupture of affected LN
Complications of strangles
dyspnea/distress
GPE
Purpura hemorrhagica
acute myositis
immune mediated myopathy
myocarditis
brain abscessation
If Strep equi locates in other LN than head/neck what is the term
Bastard strangles
Tx for strangles
Hot pack
Strict Isolation
ALL complicated cases: Penicillin (& NSAIDS - flunixin megulamine
symptomatic tx
quarantine facilities 6 mos - 1 yr
