DL: Antimircrobial therapy Flashcards
What is the first line treatment for UTI in female dogs?
Amoxicillin + TMPS
Males - Fluoroquinolone (good but reserve for severe cases), TC (not good for reaching prostate), TMPS (possible complications - dry eye. Usually use this but measure tear production).
What do you assume if a male dog has lower UTI signs?
that the prostate is involved
Causes of kennel cough/tracheobronchitis
70% cases are bacterial
Bordatella may be present
TCs (used most commonly, mycoplasma may be involved)
Fluoroquinolones (only if absolutely necessary)
Is strangles usually treated with ABs?
No despite it being caused by Streptococcus equi. because the bacteria reside in abscesses. If the case is acute and abscesses haven’t developed within LNs then treat with ABs. Infective for up to 3 weeks after clearing abscess so practice good hygiene.
How might you treat suspect septo-peritonities after rupture from SI and LI biopsies?
Fluoroquinolones - target gram negative
Metronidazole - targets gram negative
Other: fluoroquinolone + clindamycin OR fluoroquinolone + metronidazole OR fluoroquinolone + penicillin
ADMINISTER: IV
Define hyperaesthetic
increased sensitivity of any sense organ
Define abnormal nystagmus
continuous, uncontrolled to and fro movement of the eyes
What often causes bacterial meningitis in calves? How would you treat this?
E.coli (often) - use ‘green’ ABs against this sch as fluoroquinolones, aminoglycosides, 2nd/3rd generation cephalosporins, ticarcillin-clavulanate
What rule should be remembered when giving hindgut fermenters antibiotics?
PLACE rule if giving the ABs orally
What is Enrofloxacin used for?
Common AB given to rabbits
Not active against anaerobes (abscesses often contain these)
What bacteria are most likely to be present in an abscess?
Anaerobes
Pasteurella and Staph (maybe)
Treatment - abscess with pus - cat
AB must be effective against anaerobes
Cephalosporin - best
lincosamides (clindomycin)
amoxicillin - also excellent option, not with clavulanic acid
What is Covenia?
a 3rd generation cephalosporin (for critical illnesses only)
long acting (2 weeeks)
Behaves more like a 1st generation cephalosporin
How do you treat pyoderma and deep pyoderma?
Pyoderma - ABs not indicated, topical treatment, antiseptic shampoo
Deep pyoderma - usually requires ABs (cephalosporin), long treatment time (often 6-8 weeks)
Possible causes of mastitis
E.coli/coliforms - severe clinical Staph - chronic Strep - chronic Mycoplasma Pasteurella
