INCIDENCE OF PATHOGENIC BACTERIA IN RESPIRATORY INFECTIONS

摘要

A study was undertaken to evaluate the "Incidence of pathogenic bacteria in respiratory infections" carried out in 100 symptomatic cases (Males-62; Females-38). One himdred Samples were collected from the patients of respiratory infections out of which 56-Sputum samples were collected from lower respiratory tract and 44-Throat swabs collected from upper respiratory tract and these Samples were processed by Gram stain, Ziehl Neelsen stain, Culttire and sensitivity. Out of 56 Sputxmi samples, culture positivity is 69.64% in which commonest organism was "Staphylococcus aureus". In Throat swab culture positivity is 36.36%, out of 16 culture positive samples 18 organisms were isolated in which "Streptococcus pyogenes" was commonest organism. 100 sampleswere screened for tuberculosis bacteria out of which 24 samples were positive with Z-N stain culture not done for Mycobacterium tuberculosis. "Staphylococcus aureus" and "Mycobacterium tuberculosis" shows highest incidence in respiratory tract infections. In upper respiratory system "Streptococcus pyogenes" was most predominant organism, where as in lower respiratory system "Staphylococcus aureus" was most predominant organism. The highest incidence of pathogenic bacteria in the category of "House holders" and Farmers" this may be due to the constant exposure to the polluted air.
