Bacterial profile and risk factors associated with typical pneumonia

Abstract EN

The main aim of this study was to detect the bacterial profile associated with typical pneumonia.

Some risk factors represented by age, sex, residence,smoking and comorbidity illness and their effect on incidence of pneumonia were considered.

For this, a total of, 142 proofly pneumonic patients who referred to Marjan Teaching Hospital and consultant clinic for respiratory and chest diseases were studied during a six- month period from October 2012 to March 2013.

The bacterial causes were determined in 126 (88.7 %) sputum samples out of 142 samples under study.

Bacterial isolates represented by 49 isolates (34.5 %) of Streptococcus pneumoniae, 26 isolates (18.4 %) of Klebsiella pneumoniae, 21 isolates (14.8 %) of Neisseria meningitidis, 4 isolates (2.8 %) of Staphylococcus aureus, 4 isolates (2.8 %) of Haemophillus influenzae and 2 isolates (1.4 %) of Streptococcus pyogenes.

Mix growth was found in 20 isolates (14.0 %).

Patients aged above 49 years were more susceptible for pneumonia.

Males 89 cases (62.7 %) were found to be more susceptible for infection compared with females 53 cases (37.3 %).

The urban residence individuals revealed a high frequency of pneumonia 78 cases (55 %) versus 64 cases (45 %) of rural residence individuals.

Pneumonia was high incidence in smoker patients 92 (64.8 %) compared with non-smoker patients 50 (35.2).

Patients with comorbidity illness were more also susceptible to pneumonia.
