Identification, characterization and antibiotic susceptibility testing of Pseudomonas aeruginosa isolated from clinical sources

Abstract

In this study, hundred (100) specimens were collected from patients of both gender and different age groups in three government hospitals in Baghdad/Iraq from January 2022 to May 2022. Samples were diagnosed by routine, biochemical tests, and Vitek- 2 system device to diagnose the Pseudomonas aeruginosa, the results showed that 32 (32%) were P. aeruginosa bacteria.  Antibiotic susceptibility testing was performed for all 32 isolated P. aeruginosa pathogenic bacteria   and sensitivity was performed for the aminoglycoside group (Gentamycin, Amikacin, streptomycin) of antibiotics to detect isolates sensitivity or resistance to antibiotics circulating in health institutions, P. aeruginosa showed the highest antibiotic resistance to Gentamicin: 40.6%, streptomycin: 37.5%, Amikacin: 25%. In the present study our target isolates of P. aeruginosa which is resistant to Gentamicin, Amikacin and streptomycin according to our result we found the most isolates which resistant to Gentamicin, Amikacin and streptomycin are P1, P5, P8, P9, P14, P17, P18, P19, P22, P29.
