4) A Thoroughbred studfarm with endemic Rhodococcus
equi disease carries out routine ultrasonographic
screening for R. equi pneumonia. Thoracic
ultrasonography detects 3 pulmonary abscesses
approximately 1 cm in diameter to be affecting one of
the 6-month old foals. Clinical examination of the foal
38
is normal and no coughing has been observed. Based on
these findings what is the most appropriate treatment/
management plan for this foal?
a. Start treatment with azithromycin and rifampicin
b. Start treatment with doxycycline
c. Daily clinical monitoring and repeat thoracic
ultrasonography in a week’s time
d. No need for further monitoring
e. Repeat thoracic ultrasonography in a month’s time
5) A 15-year old Warmblood gelding is presented for
coughing. The gelding is stabled on sawdust in a barn
with several other horses at night and turned out during
the day. No abnormalities have been reported in the in-
contact horses. Clinical examination is normal other than
a respiratory rate of 24 breaths/minute at rest and use of a
re-breathing bag elicits expiratory wheezes. Haematology
is unremarkable. The owner does not want to pursue
further diagnostic investigation. Based on these findings
what would the most appropriate action be?
a. Prescribe a 2-week course of trimethoprim
potentiated sulphonamide
b. Prescribe a week’s course of cefquinome
c. No treatment and repeat clinical examination in 2
weeks’ time.
d. Prescribe a 2-week course of acyclovir
e. Prescribe a 2-week course of inhaled salbutamol
and beclomethasone while implementing
environmental changes such as dust-free bedding,
cleaning of the barn, increased pasture time and
soaking of hay.
