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. Keywords: Respiratory Tract Infection; Haemophilus influenzae; Moraxella catarrhalis; Streptococcus pneumonia.

ABSTRACT The in vitro activities of faropenem and other antimicrobial agents were determined against 4,725 Streptococcus pneumoniae isolates, 2,614 Haemophilus influenzae isolates, and 1,193 Moraxella catarrhalis isolates collected from 273 U.S. laboratories during 1999. Faropenem MICs at which 90% of isolates are inhibited were 0.008, 0.25, and 1 μg/ml for penicillin-susceptible, -intermediate, and -resistant S. pneumoniae strains, respectively; 0.5 and 1 μg/ml for β-lactamase-positive and -negative H. influenzae strains, respectively; and 0.12 and 0.5 μg/ml for β-lactamase-negative and -positive M. catarrhalis strains, respectively. Faropenem holds promise as an oral therapy for community-acquired respiratory tract infections.

This study was carried out to determine patient perceptions of respiratory tract infections and attitudes to taking antibiotics, thus helping doctors to have a better understanding of their patients and their requirements. Telephone interviews were conducted in the UK, Belgium, France, Italy, Spain and Turkey using standardized questionnaires directed at patients who had taken an antibiotic or given one to their child for a respiratory tract infection within the previous 12 months. Approximately 200 working adults (≤ 55 years), 200 elderly adults (> 55 years) and 200 mothers of children (< 12 years) from each country were contacted; in total, 3610 subjects. Pressure on GPs to prescribe antibiotics was highlighted by over 50% of interviewees' believing that they should be prescribed for most respiratory tract infections. Although interviewees were positive about antibiotics, with over 75% judging them to be effective and to speed recovery, some ambivalence was shown. Most patients waited 2 – 3 days before consulting their doctor and over 80% of respondents expected symptoms to improve after 3 days' treatment. This provided a natural watershed for compliance, with most defaulters stopping after 3 days because they felt better. Second only to fewer side-effects, patients ranked shorter and more convenient dosage alongside efficacy as the improvements most sought in antibiotic therapy. In conclusion, patients regarded antibiotics as important in the treatment of respiratory tract infections, with interest shown in short-course, once-daily therapy. Doctors, however, need to reassure patients that short courses will eradicate infections and have minimal adverse effects on the immune system.
