Abstract

This study was conducted to determine the incidence of bacterial pneumonia among Yemeni patients whose diagnosed clinically as a pulmonary tuberculosis infection attending the National Tuberculosis Control Center in Sana’a city, Yemen. All patients were out patients and sent to the laboratory for laboratory investigation. Patient’s age ranged from 6 to 56 years and were from both sexes. Three hundreds and eighty eight sputum samples were collected from the patients, stained and cultured on the appropriate media. Sociodemographic and health information were collected using questionnaire filled by the patients. Results showed that the rate of infection by Mycobacterium tuberculosis was 13/388 (3.4%) whereas the infection by bacterial pneumonia other than tuberculosis was 166/388 (42.8%). Isolated bacterial etiologies were; Staphylococcus aureus (17.5%), Streptococcus pneumonia (12.4%), Klebsiella pneumonia (9.8%), and Pseudomonas aeruginosa (3.1%). Pneumonia was most predominant among the age group 46-55 years and occurred more commonly among females (44%) than males (41.4%). There was statistically significant correlation between family size and pneumonia infection but the correlation between pneumonia and other predisposing illness like diabetes mellitus, arthritis, Kidney and liver diseases were not significant.
