Soft Tissue Infections associated Bacteria


AbstractObjectives: This work aimed to isolate and identify microorganisms from different clinical conditions; it is also to do anti microbial sensitivity test to recommend the most effective antimicrobial agents.Methodology: Each specimen collected from different sites of the body was subjected to well known microbiological methods for isolation and identification of certain microorganisms.All isolates were tested for sensitivity or resistance to the commonly used drugs employing Kirby-Bauer technique (1). Results: Out of the total samples studied (168) it was possible to isolate and identify 124 microorganisms from which Gram-Positive bacteria represented 50 isolates (62%) while Gram-negative bacteria represented 74 isolates (91.76%).From the Gram-positive bacteria it has been found that S. aureurs represented 25 (20.16%) isolates followed by' S. epidermidis 16 (12.90%) isolates.P. aeruginosa which is Gram-negative bacteria ranks the highest among all isolates representing 30 isolates (24.19%) followed by K. pneumonia 15 (12.90%) and proteus spp 14 (11.29%) respectively.No site of specimens was free from serratia although it is with low percentage ranging from (1.48% - 0.74%)Antimicrobial sensitivity test revealed that S. pneumonia is highly sensitive toClindamycin 90% and to Amoxicillin 90% respectively and less sensitive to vancomycin 60%.K. pneumonia revealed resistance to chloramphenicol 2% and to each of the drugs lincomycin, cloxacillin and erythromycin 40% respectively. P. aeruginosa showed high resistance to most of the drugs used In this study ranged between 10-52%.It reveals sensitivity to cefatriaxon 90% and less sensitive to ceftazidine 80% Serratia marcessens showed good sensitivity to all antimicrobial used in this study except co-trimoxazole to which it is resistant.Conclusion: Grams- negative bacteria are the predominant from which P. aeroginosa rank the highest among all isolates. No sit of specimens was free from serratia mercessens. S. pneumonia is highly sensitive to clindomycine (90%) P. aeroginosa showed high resistaice to most of the drugs used in this study.
