Abstract
The study was conducted to identify the types and frequencies of bacterial isolates from patients with Intensive Care Units-acquired infections, and to determine their antibiogram profile. One hundred and fifty four clinical samples were collected from 101 patients who developed clinical suggestion of new infections of urinary tract, lower respiratory tract or wound following the 48 hours of their admission to the Intensive Care Units. All samples were cultured on different culture media, and the isolated microorganisms were identified by the conventional bacteriological methods. The antibiogram profile of selected antibacterial agents was tested. The total number of the bacterial isolates was 69 miroorganisms. Gram-negative bacteria were more frequently encountered (82.6%) than the Gram-positive ones(17.4%) among all samples. The predominant Gram-negative isolate was E. coli (23.2%), followed by Pseudomonas spp. (21.7%), K. pneumoniae (14.5%), Proteus spp. (11.6%)., Acinetobacter spp. (8.7%), and E.aerogenes (2.9%). The predominant Gram-positive bacterial isolate was S.aureus (7.2%), followed by E. faecalis (5.8%), and S.epidermidis (4.3%). The most effective antimicrobial agents were amikacin, ciprofloxacin, vancomycin, gentamicin, chloramphenicol, and azithromycin.
