باکتری های پاتوژن جدا شده از نمونه بیماران مشکوک به عفونت ریوی

The lower respiratory tract is vulnerable to infection by a wide variety of microorganisms, because it is one of the organ systems which communicate directly with the environments. Although viruses and fungi can cause lower respiratory tract infections, bacteria are the dominant pathogens. Among bacteria the common causes of lower respiratory tract infection is Streptococcus pneumoniae, Mycoplasma pneumoniae, Staphylococcus aureus, Streptococcus pyogenes, Haemophillus influenzae and Legionella species. This study has been carried out to investigate pathogenic bacteria isolated from sputum of 220 patients with suspected pulmonary infection. The results were obtained as follow: Mycoplasma pneumoniae: 17 cases 22.7 percent, Mycobacterium tuberculosis: - cases - percent, Streptococcus pneumoniae: 17 cases 22.7 percent, Klebsiella pneumoniae: 12 cases 16 percent, Haemophillus influenzae: 10 cases 13.3 percent, Staphylococcus aureus: 15 cases 20 percent, Pseudomonas aeroginosa: 4 cases 5.3 percent.
