Bacterial Isolates in Slow Resolving Pneumonias

Abstract

Background : To study the pattern of bacterial isolates in slow resolving pneumonia (SRP) patients Methods : In this prospective study patients (n=121) fulfilling the criteria of slow resolving pneumonia, having Age > 14 years and radiological evidence of consolidation were included in the study. Patients having Age > 65 < 14 years, not giving consent for Invasive investigation, nosocomial pneumonia, atypical pneumonia, fungal and mycobacterial infections were excluded. All patients were investigated with multiple view Chest X-ray, sputum smear for Gram staining, ZN-staining, cytology & culture sensitivity for pyogenic and fungal infections. Fiber-optic Bronchoscopy and BAL analysis was utilized. Contrast enhanced CT scan was employed for accurate definition of the lesion. Samples were sent for microbiological evaluation. Result: Age group was 14-65 years with median age 53 years. One hundred and twenty one pyogenic bacterial isolates were obtained. Gram negative bacteria were 66.11% while gram positive bacteria were 30.57 % and mixed growth were seen in 3.30%. Conclusion : Gram negative etiology predominates in SRP cases with pseudomonas at the top followed by klebsiella.
