Isolation and identification of the organisms was done by using standard microbiological methods. Results: Out of a total of 430 sputum samples collected across the three senatorial districts in Ondo State for the study; three hundred and ninety sputum samples (90.7%) had bacterial growth with the break down as follows: Streptococcus pneumoniae (230; 59%), Staphylococcus aureus (115; 29%) and Klebsiella pneumoniae (45; 12%) Conclusion: Streptococcus pneumoniae (59%) is the most prevalent cause of pneumonia among the patients attending the selected government hospitals in Ondo State, Southwest, Nigeria.
