7) A 5 year-old Friesian stallion is presented with
pneumonia. While awaiting results of culture and
sensitivity of a transtracheal aspirate, empirical
antimicrobial treatment is initiated with penicillin,
gentamicin and metronidazole. Three days later aerobic
bacterial culture of the aspirate grows a Streptococcus

enrofloxacin. Anaerobic culture is negative. Clinical signs
are improving but haematology still reveals a mild mature

regards to good antimicrobial stewardship?
a. Stop gentamicin and metronidazole treatment
but continue penicillin treatment. Review need for
continued penicillin treatment in 2-days’ time.
b. Continue penicillin, gentamicin and metronidazole
treatment. Review need for continued antimicrobial
treatment in 2-days’ time.
c. Stop all antimicrobial treatment and continue daily
clinical monitoring.
d. Stop penicillin, gentamicin and metronidazole
treatment and start enrofloxacin treatment. Review
need for continued enrofloxacin treatment in 2-days’
time.
e. Continue penicillin, gentamicin and metronidazole
treatment for a minimum of 14 days regardless of
clinical findings.

practice?
a. Doxycycline
b. Enrofloxacin
c. Ceftiofur
