Abstract:
This study was carried out in Khartoum state during the period from
November 2008 to March 2009, to isolate S. pneumoniae in patients with
lower respiratory tract infections. One hundred sputum specimens were
collected from patients attended to Abu- Anga hospital. Ziehl Neelsen
stain was done for all specimens, then the specimens were cultured on
Blood agar, Chocolate agar and MacConkey's agar for primary isolation
of pathogens. Identification of the isolates were done by colonial
morphology ,gram's stain, biochemical tests and API 20 Strep.
Out of the enrolled specimens examined, 33 specimens were showed
Acid Fast Bacilli, 12 were S. pneumoniae, 2 were S. faecium, 4 were S.
oralis, 3 were S. salivurius, 5 were S. viridans, 3 were S. aureus, 3
were Lactobacilli, 2 were S. pyogenes, 5 were S. mitis, 7 were
Unidentified isolates, 3 were K. pneumoniae, 2 were S. sanguinis, 9 were
aerobic actinomycetes. 7 were no growth .
The study concluded that S. pneumoniae consider as a major cause of
lower respiratory tract infection in Khartoum state, hence more attention
