NT= not tested, Klebsiella spp. = other Klebsiella species. P = penicillin, CTR= ceftriaxone, GN = gentamicin, AK= amikacin, COT= co-trimoxazole, TE = tetracycline, C = chloramphenicol, CIP = ciprofloxacin, MET= methicillin, ERY= erythromycin, S= susceptible, and R= resistant. % is computed from each cell. Total= total calculated from both Gram negative and positive isolates for that specific antibiotics were tested.
