Bacteriological and Physiological Study of bacterial infection of the blood stream


The study was included to collect one hundred blood samples of peoples suspected with Bacteremia at different ages and both sex Kirkuk General Hospital and Azadi Hospital. The results indurated to found positive bacterial growth at 16 blood samples, while 86 samples found negative bacterial growth. The 11 isolates was appear as gram positive bacteria, while Ten of them were as Staphylococcus species, one was Clostridium perfringens, and Five isolates Gram negative bacteria, Burkloderia cepacia, Pseudomonas alcaligenese, Stenotrophonas maltiphilia, Klebsiella pneumonia, and Escherichia – coli. all Staphylococcus isolates were appear are sensitive to imipenem, vancomycin, followed by the amoxicillin - clavulanic acid for 8 isolates and Ceftriaxone, Chloramphenicol and Amikacin were sensitive to 7 isolates while all Staphylococcus isolates were resistance to cefixime followed by azithromycin, erythromycin. The study showed Stenotrophomonas mltophilia were the most resistant antimicrobial isolates used in the study. The results of the physiological tests showed that the PCV values were lower in most blood samples of patients with bacteremia, whereas increased values for Clotting time, WBC due to toxic effects of invasive bacteria.
