Background: Lower respiratory tract infections (LTRIs) are emerging as the most common infectious diseases of humans. Antibiotic resistance has increased in all the major pathogens therefore, this project engrossed on defining the current drift of bacterial etiologies of respiratory tract infections among the patients and their antimicrobial susceptibility pattern. Methods: This cross-sectional study with non-probability consecutive sampling was conducted in the microbiology laboratory of Ziauddin Hospital. Bacterial isolates (163) were recuperated from respiratory sputum specimens obtained from patients with lower respiratory tract infections. The pathogens collected for study were Streptococcus pneumonia, Haemophilus influenzae, and Moraxella catarrhalis. Frequencies and percentages were computed for categorical variables like microorganism, gender, age, duration of lower respiratory tract infections, etc. Mean and standard deviation were calculated for quantitative variables like age and infection duration. Furthermore, duration of disease was stratified by post stratification Chi Square with p value ≤ 0.05 was considered significant. Results: Most commonly isolated pathogen is Moraxella catarrhalis 72.39% followed by Haemophilus influenza 14.72% and Streptococcus pneumonia 12.88%. For Streptococcus pneumoniae 47% sensitivity showed to Ampicillin, 52% Penicillin, 61.9% Erythromycin and 57% to Ceftriaxone. For Haemophilus influenzae 100%, sensitivity showed to Ceftriaxone, 100% Amoxicillin and 62.5% Co-trimoxazole. Similarly, for Moraxella catarrhalis 54% sensitivity was showed to Erythromycin, 100% Ceftriaxone and 27% with Levofloxacin. Conclusion: Moraxella catarrhalis, Haemophilus influenzae and Streptococcus pneumoniae were the most common bacterial isolates recovered from LTRIs. We found M. catarrhalis resistant rate was elevated for Levofloxacin, Streptococcus pneumonia for Co-trimoxazole and Haemophilus influenzae to all β-lactams.
