Characterisation of Antibiotic Resistance Pattern of Enterococcus Faecalis and Enterococcus Faecium Isolated from Different Clinical Specimen in Al-Muthanna Province, Iraq

Abstract

Spread of Enterococci has increased, causing serious infections that sometimes lead to death. Therefore, the study aimed to determine the prevalence of Enterococci in Al-Muthanna Governorate and their resistance patterns to antibiotics. Samples were collected from Al-Hussein Teaching Hospital, as well as Women and Children's Hospital in October 2023. Cultural diagnosis and biochemical tests confirmed sixty-three E. faecalis, and eighteen E. faecium isolates. Most infections being prevalent among females 71.6 % and young people aged from 21 to 30 years old in rural areas. Antibiotic resistance rates for E. faecalis were meropenem 100 %, tetracycline 65 %, ampicillin 63.4 %, azithromycin 12.6 %, ciprofloxacin 42.8 %, AMC 17.4 %, vancomycin 15.8 %, teicoplanin 7.9 %, and nitrofurantoin 7.9 %. Resistance rates for E. faecium, were meropenem 94.4 %, tetracycline 66.6 %, ampicillin 61.1 %, azithromycin 77.8 %, ciprofloxacin 44.4 %, AMC 22.2 %, vancomycin 33.3 %, teicoplanin 16.6 %, and nitrofurantoin 5.5 %.
