Antibiotic Disk abbreviations

[karaduman]

I have a Medical Microbiology Report to give in soon and I am stuck at the simplest part. I did an Antibiotic Sensitivity Test for E. Coli and had to use 4 different antibiotics which were:
Ampicillin(25mg/ml) trimethoprim, naladixic acid and cephlaexin disc. Now as you know the disks used for this test have an abbreviation on them which were:
Amp, CL, W, NA.

Can anyone confirm which abbreviation goes with which antibiotic please. I mean Ampicillin is Amp and I am assuming NA is naladixic acid. No idea about the other two

Thanks

Weird abbreviations. But you can work it out, you got those two right. Since cephlaexin has a C and L in it is safe to say that CL is the abbreviation. Which leaves W to mean trimehoprim.

If you look at the abbreviations used by BD here:

Amp and NA seems correct, but the other are unknown. But maybe a different manufacturer use different codes? In this case I would agree with Darwin420

Thanks guys. I think I figured it out. As you mentioned the first two makes sense and by looking at Wiki I found out that Trimethoprim is abbreviated into W, which just leaves CL being Cephalexin Acid.

Thanks for the replies.
