Abstract

In this research, a study was conducted isolating and identification of Pseudomonas aeruginosa bacteria from clinical samples from various pathological conditions such as burns , otitis media , urinary tract infection , wounds, eye infection, blood infection, catheter infection, throat , vaginal infection and surgical. The present study includes 313 samples collected from patients who attend Alsader Medical City and Al- Hakim General Hospital during the period extended From September 2023 to December 2023 ( men and women ) with age groups between (1 -77) years. The identification of bacterial isolates were detected by classical and molecular technique (PCR), were the frequency among males 163 (52.07% ) was more than that in female 150 (47.92). The samples distribution is made according age group , it appears high for the following high (15.97) and (12.77) with group (16-30) years of male and female respectively . The results revealed that 57/313 specimens of the total number of samples are Pseudomonas aeruginosa by identified according to their morphological, physiological and biochemical properties. Also with molecular identification by using four primers wre the results showed 16S rRNA gene was detected in 57/57 (100%) P. aeruginosa isolates , the Las biofilm gene was detected in 43/57 (75.43%) , the algD gene was detected in 41/57 (71.92%) and 41/57 samples show positive results with the oprL gene. Six types of antibiotics were also tested to determine the resistance of the samples to them.
