Neonatal Bacteriemia Isolates and Their Antibiotic Resistance Pattern in Neonatal Insensitive Care Unit (NICU) at Beasat Hospital, Sanandaj, Iran
Bacteremia continues to result in significant morbidity and mortality, particularly among neonates. There is scarce data on neonatal bacteremia in among Iranian neonates. In this study, we determined neonatal bacteremia isolates and their antibiotic resistance pattern in neonatal insensitive care unit at Beasat hospital, Sanandaj, Iran. During one year, all neonates admitted to the NICU were evaluated. Staphylococcal isolates were subjected to determine the prevalence of MRS and mecA gene. A total of 355 blood cultures from suspected cases of sepsis were processed, of which 27 (7.6%) were positive for bacterial growth. Of the 27 isolates, 20 (74%) were Staphylococcus spp as the leading cause of bacteremia. The incidence of Gram negative bacteria was 04 (14.8%). The isolated bacteria were resistant to commonly used antibiotics. Maximum resistance among Staphylococcus spp was against Penicillin, and Ampicillin. In our study, the isolated bacteria were 7.5 % Vancomycin and Ciprofloxacin sensitive. Oxacillin disk diffusion and PCR screened 35% and 30% mec a positive Staphylococcus spp. The spectrum of neonatal bacteremia as seen in NICU at Beasat hospital confirmed the importance of pathogens such as Staphylococcus spp. Penicillin, Ampicillin and Cotrimoxazol resistance was high in theses isolates with high mecA gene carriage, probably due to antibiotic selection.
