The organism is correct.
I am looking for two specific drugs, but I can tell you it's not in the penicillin and cephalosporin classes.
Aztreonam, lipopeptides, Penicillin with anti betalactamase preps,fluoroquinolones and aminoglycosides
Definitely one of those.
I forgot about carbapenems (meropenem), and maybe Aztreonam.
Other guess is under the aminoglycosides(gentamicin).
I'm cheating with using the CLSI manual :P
We throw in a battery of antibiotics instead of the ideal few selected options. None of what we do here is ideal but we try to be close so I don't really expect I'm going to get this right haha. Manual etest are done often here and like supply issues that's been happening, I have seen an increase of their use lately.
Those are not it.
Feel free to cheat. That's why I'm making it non-straight forward.
Ciprofloxacin
Imipenem
You mentioned it's not under Penicillin. Regarding the group above where you mentioned one of those, Penicillin + Tazobactam and other Penicillin combinations are out?
Maybe @scholaris and @nikv wants to try too :P
I'm guessing Ciprofloxacin was the right one. Currently at work so I'll review on this later.
Amikacin and Ciprofloxacin
If Piperacillin class was out but not their combinations
Piperacillin Tazobactam and Ciprofloxacin.
Tobramycin and Ciprofloxacin, entertaining that maybe folks here just prefer amik as an aminoglycoside than Tobramycin.
The other one may be Polymixin or Colistin
Then another Doripenem as the last one for the carbapenem class which I haven't tried.
