Respiratory tract infections are believed to be one of the main reasons why people visit their GP or pharmacist. Respiratory tract infections (RTIs) are the leading cause of Death in USA. Lower respiratory tract infections( LRIs) are generally more serious than upper respiratory infections. LRIs are the leading cause of death among all infectious diseases. The two most common LRIs are bronchitis and pneumonia. Typical infections of the upper respiratory tract include tonsillitis, pharyngitis, laryngitis, sinusitis, otitis media . The aims of our study are strengthening of surveys of the cases of the respiratory tract infection , the causes of respiratory tract infection ,then evaluate the number of persons who have negative result and the reason for this lack of screening for all pathogenic virus and search for bacterial infection only , finally culture characterization and antibiotic susceptibility testing of the isolated pathogenic bacteria. In order to reach those goals we carried out a survey of 635 throat swabs and sputum sample in the Department of Microbiology at Central Laboratory of the Ministry of Health in Amman the capital of Jordan between January 2013 to December 2014 using of throat and sputum , culture and biochemical test and antisera have been did . Atotal of 635 individuals (275 males and 360 females) swabs and sputum were tested for bacterial infection , a total 55 throat swabs were gave positive results for Group A beta-hemolytic streptococci of with an overall prevalence of 8.7 %. Atotal 23 sputum samples were gave positive results for different types of bacterial infection with an overall prevalence of 10 %. Then to report the information about their antibiotic susceptibility. In conclusions Group A beta-hemolytic streptococci the most common cause the upper respiratory tract infection. But K. pneumonia the most common cause of lower respiratory tract infection.
