Abstract Background Lymphoedema is caused by dysfunction of the lymphatic system resulting in accumulation of high-protein content fluid in the interstitial space. To date, the bacteria associated with wound infections of patients with lower limb lymphoedema in Ethiopia have not been studied. This study identified pathogenic bacteria involved in wound infection and assessed antimicrobial susceptibility patterns in patients with lymphoedema in Ethiopia. Methods Swab samples were collected from the wounds of patients with lymphoedema and cultured using standard microbiological techniques. Micro-organisms were identified by colony morphology followed by identification and antimicrobial susceptibility testing using the automated VITEK 2 COMPACT Microbial Detection System. Results Swabs were collected from 103 patients and 84 were culture positive: 44 (52.4%) culture-positive samples showed polymicrobial growth and 40 (47.6%) grew single bacterial isolates. In total, 134 isolates were obtained, of which 26 gram-negative and 12 gram-positive bacterial species were identified. A total of 28/63 (44.4%) gram-negative isolates and 3/57 (5.3%) gram-positive isolates were multiple drug resistant. There was no resistance to ciprofloxacin, moxifloxacin or gentamycin among gram-negative or gram-positive bacteria. Conclusion In this study, many infections were polymicrobial and showed multiple drug resistance. Fluoroquinolones and gentamycin, however, seemed to be effective against bacterial wound infection in this setting.
