ANTIBIOTIC RESISTANCE PATTERN IN BACTERIA ISOLATED FROM ORTHOPAEDIC RELATED INFECTIONS

Le résumé fourni par la source

Background. Orthopaedics & Implant related infections continue to pose a problem for the orthopaedicians. An increase in the number of multidrug resistant bacteria stresses the value of an adequate diagnosis, leading to a proper therapy of these patients. To isolate bacteria causing orthopaedic related infecti Objective. Materials ons and determine their antibiotic resistance pattern. & methods. A total of 111 samples were received during the study period in the Department of Microbiology & were processed. Bacteria causing orthopaedic related infections were isolated and their antimicrobial susceptibility testing was determined. . There were 66 (59%) isolates Results that showed culture positivity & were processed. Among which, gram positive cocci were 35 (53%) & gram negative bacilli were 31 (47%). The common gram positive cocci were Methicillin sensitive Staphylococcus aureus 31.81% followed by CoNS 10.6% & MRSA 10.6% While the common gram negative bacilli were Pseudomonas aeruginosa 18.18%, Klebsiella pneumoniae 12.12%, Escherichia coli 7.5%, Citrobacter freundii 4.5%, Proteus mirabilis 3.03% & Acinetobacter baumannii 1.51%. Most of the gram positive cocci were resistance to the following antibiotics- ciprooxacin, penicillin, erythromycin. Most of the gram negative bacilli were resistance to the cephalosporins group of drugs mainly ceftriaxone & ceftazidime . Gram positive cocci were the commone Conclusion st isolates from orthopaedic related infection as compare to gram negative bacteria. Antibiotic resistance pattern should be given adequate stress so as to get better results regarding orthopaedic related infections
