It is part of the routine of the laboratory to test the drugs most used by veterinarians, in this way the 17 active ingredients used in this sensitivity tests were: PMN = novobiocin (40 [micro]g)+penicillin G procaine (40 [micro]g); CEQ = cefquinome (30 [micro]g); AMO = amoxicillin (10 [micro]g); DUL = danofloxacin (5 [micro]g); CTF = ceftiofur (30 [micro]g); CL = cephalexin (30 [micro]g); CN = gentamicin (10 [micro]g); TE = tetracycline (30 [micro]g); AM = ampicillin (10 [micro]g); ENO = enrofloxacin (5 [micro]g); NEO = neomycin (30 [micro]g); SUT = sulfatrim (25 [micro]g); AMC = ampicillin+colistin (30 [micro]g); CNM = cefalonium (30 [micro]g); ACA = amoxicillin (20 [micro]g) +clavulanic acid (10 [micro]g); OXA = oxacillin (1 [micro]g); and CIP = ciprofloxacin (5 [micro]g).
They found that all of the species isolated have sensitivity for enrofloxacin, fluorphenikol and ciprofloxacin; and also for amoxicillin, ampicillin, bacitracin, erythromycin, fucidic acid, gentamicin, chloramphenicol, lincomycin, nalidixic acid, neomycin, novobiocin, oxytetracycline, cefoxitin and sulfamethoxazole-trimethoprim at varying levels.

1 mL of this sample was added to two broth cultures (Selenite cysteine and Tetrathionate broth) that contained iodine and novobiocin, then was incubated at 35 [degrees]C and 41.
