Nasal and Pharyngeal Colonization by Bacterial Pathogens: A Comparative Study between Preclinical and Clinical Sciences Medical Students

Table 4

Antibiotic resistance pattern of pharyngeal isolates.

Organism (number)	Antibiotics (resistant percentage)
	P	CIP	COT	C	CTR	AZM	E
Haemophilus influenzae (25)	—	1 (4%)	3 (12%)	1 (4%)	00	5 (20%)	—
Haemophilus parainfluenzae (7)	—	1 (14.3%)	1 (14.3%)	00	00	00	—
Beta-hemolytic streptococci (11)	00	00	00	—	00	—	—
Streptococcus pneumoniae (8)	3 (37.5%)	00	00	—	00	—	2 (25%)

Four isolates of beta-hemolytic streptococci (45.4%) were intermediate sensitive to penicillin. AZM: azithromycin, CIP: ciprofloxacin, CTR: ceftriaxone, COT: cotrimoxazole, C: chloramphenicol, E: erythromycin, P: penicillin.
