Abstract
The study involve the diagnosis of (37) bacterial isolate from (35) patient which suffering from lower respiratory tract infections at tuberculosis & thoracic diseases treatment center in Tikrit city & (20) normal individual represent control samples for the period from (3/1/2011) to (20/7/2011) by which the culture results of patients sputum were positive & bacterial isolates are diagnosed according to the different morphological & biochemical assayes for S. pneumonia S aureus , P. aeruginosa , E .coli & S. pneumonia was most common & represent (37.8)% .The present study include also the antimicrobial activity assay of four extracts types of common used plants in traditional medicine which are ( Peganum harmala , Eucalyptus , Thymus vulgaris , Matricaria chamomilla) on the previous mentioned bacterial types & using of three antibiotics as standard control samples for bacteria by which the results show that both the aquatic& alcoholic extracts of harmala& Eucalyptus have inhibitary activity against all bacteria . In this study while the aquatic extract of Thymus vulgaris , Matricaria chamomilla Show no activity on P.aeruginosa & also show no activitiy on the other isolates in comparison with chloramphenicol & ciprofloxacin antibiotics but show moderate activity against the other bacteria in this study in comparison with Tetracycline control antibiotic , while with Tetracycline control antibiotic , while alcoholic extract of Thymus vulgaris , Matricaria chamomilla Show variant inhibitary activity ranged between high to moderate against bacterial isolates in the present study .
