2 - The distribution of the microorganisms that have been isolated from wound and abscesses in consideration of clinics and their antibiotic susceptibility
Mustafa Gül, Engin Seber
Objective: In this study, the distribution of wound and abscess samples according to clinics and isolated bacteria antibiotic susceptibility were examined which were sent to Microbiology and Clinical Microbiology Laboratory.
Study Design: 388 wound and abscess samples which were sent to Şişli Etfal Training and Research Hospital were inoculated 5% blood agar, chocolate agar and Eozin-Methylen Blue agar. In these media, reproduced bacteria were defined and antibiotic susceptibility was determined by using disc diffusion test.
Result: The samples were usually from Surgical departments, mostly belong to Ortopedics Clinics. Although 239 (61.5%) of samples were reproduced, 149 (38.4%) of them were not reproduced. Among the 239 of samples, 122 (51%) were Gram positive bacteria, 117 (48.9%) were Gram negative bacteria. Although methicillin resistant Staphylococcus aureus and methicillin resistant coagulase negative staphylococcus which were isolated from Gram positive bacteria were found to be 100% sensitive to vancomycin and teicoplain, they found less sensitive (17%- 65%) to other antibiotics . Methicillin sensitive Staphylococcus aureus and methicillin sensitive coagulase negative staphylococcus were found I2%-38% sensitive to other antibiotics. Alfa hemolytic streptococcus were determined 75% sensitive to penicillin G and beta hemolytic streptococcus were ¡00% sensitive to penicillin G. From Gram negative bacteria, Pseudomonas spp. were found to be 89% susceptible to imipenem and 75% susceptible to amikacin, Acinetobacter spp. 90% susceptible to imipenem, 76% susceptible to ciprofloxacin and 75% susceptible to amikacin, Klebsiella spp. 100% susceptible to imipenem, 90% susceptible to ciprofloxacin and ofloxacin, 80% susceptible to ceftriaxone, 76% susceptible to cefoxitin but they found to be 20%-70% susceptible to other antibiotics. E.coli and Proteus spp. were found to be 35%-55% susceptible to ampicillin but 65%-100% susceptible to other antibiotics.
Conclusions: Wound infections and abscess were encountered mostly at Surgical departments. The factors that were occured in infections showed difference to clinics . For an effective treatment, clinicians have to start empirical treatment on the necessary situations and it is useful for them to know the antibiotic susceptibility of agent bacteria.
