Diameter zone of inhibition of antibiotic discs against bacteria species and resistance status.

Antibiotic	Diameter zone of inhibition (DZI) in mm
	Bacterium
	S. epidermidis	S. aureus	S. saprophyticus	E. coli	K. pneumoniae	S. typhi
Ceftriaxone	22 (R)	25 (I)	38 (S)	25 (S)	24 (S)	20
Amoxicillin	6 (R)	6 (R)	6 (R)	30 (S)	6 (R)	6 (I)
Ampicillin	6 (R)	6 (R)	17 (S)	30 (S)	6 (R)	6 (R)
Norfloxacin	32 (S)	30 (S)	36 (S)	10 (R)	31 (S)	30 (S)

R = resistant; I = intermediate; S = sensitive. S. epidermidis resistant to Ceftriaxone (CRO), Amoxicillin (AMX), and Ampicillin (AMP); S. aureus resistant to CRO, AMX, and AMP; S. saprophyticus resistant to AMX; E. coli resistant to Norfloxacin (NOR); K. pneumonia resistant to AMX and AMP; S. typhi resistant to CRO, AMX, and AMP.
