In routine stool samples susceptibility testing is not always required,
however, I take the attitude that we should perform, record but not
report results unless requested for good clinical reasons.  Such reasons
inlcude growth in blood, a severely unwell neonate or even infant, and
immunocompromised patient.

In Darwin we tend to treat alot of our _Shigella_ cases because many are
also malnourished at the same time.

What to report, well we all know aminoglycosides are a waste in these
cases.  I report ampicillin (remember amp is better than amox in
_Shigella_), co-trimoxazole and if systemic infection a third generation
cephalosporin.  I usually telephone the results anyway and will discuss
with the clinician the case.  Sometimes, if they can be managed as an
outpatient, I might prescribe norfloxacin.  Of course in _Salmonella_
Typhi I use ciprofloxacin, but in non-Typhi _Salmonella_ without
systemic features I restrict the use of that quinolone.

Hope this helps.
