A total of 514 samples including 196 nasal swabs, 148 tracheal swabs and 170 pneumonic lung tissues were collected: 460 isolates were identified. The isolates constituted 9 genera of bacteria with 82.40 per cent Gram positive organisms and 15 per cent Gram negative organisms and mixed organisms as 2.6 per cent. Staphylococcus aureus and Corynebacterium pyogenes were the predominant isolates with frequency of 24.8 and 20.6 per cent respectively. Staphylococcus aureus, Coryn. pyogenes, Streptococcus. pyogenes and Klebsiella pneumoniae showed high frequency of isolation from pneumonic lungs as compared with their isolation frequencies from nasal cavity and the trachea. In an in vitro antibiotic sensitivity tests, penicillin, ampicillin were the drugs of choice against Gram positive organisms. Gentamicin showed a marked inhibitory effect against both Gram positive and Gram negative bacteria.
