The study was carried out to isolate and identify the common Bacteria causing respiratory tract infections among patients attending Aminu Kano Teaching Hospital between August and October, 2011, and the current sensitivity patterns of the isolated bacteria to common commercially antibiotic prepared disc. Fourty three (43) bacterial pathogens were isolated from two hundred (200) samples collected. Streptococcus pneumoniae (25.6%) has the highest percentage of occurrence, followed by Klebsiella pneumoniae (20.9%), Escherichia coli (20.9%) and Staphylococcus aureus, (16.3%) respectively. Others include Proteus species (4.7%), Pseudomonas aeruginosa (4.7%), Haemophilus influenzae (4.7%) and Serratia species (2.3%) as well. Age ranges 20 – 29 and 30 – 39 have the highest percentage of pathogens isolated. The sensitivity patterns of the isolated bacteria to commercially antibiotic prepared disc indicated that drugs likes Ceftriaxone, Ceftazidine, Ciprofloxacin, Ofloxacin, Gentamicin and Chloramphenicol shows activity on all the pathogens isolated.
