Abstract

Background and aims: Sepsis is one of the serious infectious diseases in the neonates and infants that is potentially life threatening. The aim of the current study was to identify coagulase negative Staphylococcus and their antibiotic resistance patterns in Neonatal Sepsis in the neonates and infants hospitalized at Ghrazi Hospital, Sirjan. Methods: In the cross-sectional study, 140 blood samples were obtained from neonates and infants hospitalized in a period of time from June to November 2015 in the Sirjan, Kerman and then evaluated based on many items such as: BC(blood culture)/sex/age/admission date/weight/type of birth/admission ward/clinical findings/predisposing factors. All of these informations were acquired from patients profile. All of the isolated S. epidermidis strains were confirmed by PCR. Antibiotic susceptibility test was performed by disk diffusion method. Results: of 140 blood samples, 10 CoNS strains were isolated. Evaluation of EDTA tube and molecular identification confirmed that 6 isolates were S. epidermidis. The results of disk diffusion test showed that most of them were susceptible to vancomycin and novobiocin and the most of them were resistance to cefixime, ceftriaxone and Cephalexin. In the work, half of strains (50%) were resistance to oxacillin. So, they were methicillin resistance S. epidermidis (MRSE). Conclusion: Coagulase negative Staphylococcus (S. epidermidis) is most common cause of sepsis. The specificity and sensitivity of PCR for detection of this strains in the emergency condition was useful.
