Abstract

Introduction: Pneumonia is the inflammation of the lung and several bacterial etiological agents are known
to cause the infection. Studies have shown several gram negative bacteria including Pseudomonas spp,
Klebsiella spp and gram positive bacteria such as Streptococcus spp are known to cause infection. In the
present study we aim to evaluate the spectrum of bacterial isolates and their antibiotic sensitivity pattern
isolated from BAL specimen.
Materials and Methods: The retrospective study was carried out in a tertiary care center over a period of
one year. The isolates were evaluated and identified with antibiotic sensitivity pattern.
Results: The overall BAL specimen processed in a year were 90, in which culture were positive in
28 cases (31%). The organisms isolated were Pseudomonas aeruginosa , grown in 15 cases (52%),
Klebsiella pneumoniae grown in 7 cases (28%), Escherichia.coli grown in 3 cases (10%) and Streptococcus
pneumoniae in 3 cases (10%). Most of the organisms are sensitive to antibiotics .
Conclusion: The present study has shown the most common isolate at our tertiary centre was Pseudomonas
aeruginosa, followed by Klebsiella spp and in gram positive bacteria the common organism isolated was
Streptococcus pneumoniae. Our results contribute to evaluate the common prevalent organisms causing
pneumonia and also helps in improving the epidemiological knowledge.
