A bacteriological study of septicemia in Hilla city

Abstract

Septicemia is a serious bloodstream infection; it can quickly become life-threatening. The current study aimed to isolate and identify the causative agents of septicemia cases with reference to the antibiogram test. 52 blood samples were collected from a number of incomings and those who lie in Hilla general hospital. After incubation and culturing on suitable media, 30 samples gave growth of one or two species of bacteria. A total of 33 bacterial isolates were obtained, most of them (16 isolates) were belong to coagulase-negative Staphylococcus spp., followed by E. coli (6 isolates), Pseudomonas sp. (5 isolates), Streptococcus sp. (2 isolates), and one isolate for each of Staphylococcus aureus, Streptococcus pneumonia, Acinetobacter sp., and Listeria monocytogenes. When antibiotics sensitivity test was accomplished, most Staphylococcus spp. were sensitive for daptomycin and had high resistance to both of vancomycin and clindamycin, whereas Staphylococcus aureus was sensitive for most the used antibiotics. Half of E. coli isolates were sensitive, while the second half were resistant to the used antibiotics. Imipenem inhibited the growth of all Pseudomonas isolates, whereas 80% of them were resistant to amikacin. The epidemiology of bacteremia is altering with the aging of the population, shifts in healthcare, and progress in medicine, such as increased use of immunosuppressive treatment, intravascular devices, and invasive procedures.
