Abstract
Although Staphylococcus epidermidis was once thought to be a non-pathogenic bacterium, it is now understood to be an opportunistic organism that causes a variety of nosocomial illnesses. S. epidermidis-colonized people are possible reservoirs for nosocomial infection transmission, which could be harmful to public health, particularly if there are antibiotic-resistant strains present. The aim of this research is the molecular detection of S. epidermidis, isolated from patients admitted to the orthopaedic ward of SYMH, Birnin Kebbi. A total number of 117 wound swab samples were collected from orthopaedic patients. Only 13 S. epidermidis were identified using phenotypic methods. The prevalence of S. epidermidis in orthopaedic patients was 13 (11.11%) the isolates were examined with antibiotics using the disc diffusion method. Clinical Laboratory Standard Institute Modified Kirby Bour techniques were used to determine the resistant status of recovered bacterial isolates. The results show that the isolates were 69.23%, resistant to Amoxicillin/clavulanic acid, 92.30% resistant to Meropenem, 100% resistant to Cefpodoxime, Cefepime, Cefotaxime and 30.76% resistant to Imipenem. PCR and Sanger sequence typing techniques were used to further identify the isolates, and only one S. epidermidis isolate was confirmed. S. epidermidis is among the major agents of wound infection at the Sir Yahaya Memorial Hospital in Birnin Kebbi, Nigeria. S. epidermidis isolates exhibited resistance to most of the antibiotics tested in this study. The high incidence of S.epidermidis isolates resistant to antibiotics tested in the hospital calls for urgent need to put in place measures to curtail the spread of nosocomial pathogens, especially S. epidermidis which has a high proportion of resistance in the hospital.
