Incidence of secondary Klebsiella pneumoniae infections associated with tuberculosis patients attending Aminu Kano Teaching Hospital, Nigeria

Abstract

One third of the world’s populations are thought to be infected with Mycobacterium tuberculosis, and new infections occur at a rate of about one per second. Secondary by Klebsiella pneumonia resulting to secondary infection among TB patients which causes tissue destruction and ulceration which had already occurred as a result of primary infection. This study aimed at assessing the incidence of Klebsiella pneumonia infections associated with TB patients attending Aminu Kano Teaching Hospital (AKTH), Kano. A total of 206 sputum samples were collected from TB patients attending AKTH across age groups and sex. Using a sterile swab, a portion of the sputum sample was transferred to plates of Chocolate and McKonkey agar, streaked for isolation using sterilized inoculating wire loop. All the plates were incubated in anaerobic state at 36⁰C for 24hrs. Plates were examined for growth and colonies were Gram stained and sub-cultured to appropriate media for biochemical identification. The result revealed higher K. pneumoniae incidence among the male subjects, 23 (19.33%), also highest incidence was observed among the age range of 0-14 years. This finding may assist in the early recognition and diagnosis of persons likely to be at an increased risk for TB complications.
