Goal: The coagulate negative staphylococcus (KNS) species, which are the normal flora element of the skin, are the most frequently isolated microorganisms in the blood culture in the newborn intensive care units, and the infection-contamination distinction is difficult. In this retrospective study, we present our approaches to the reproduction of KNS in the blood culture of newborn intensive care patients. Tools and Methods: In our hospital, newborn intensive care units were taken to work with newborns who were found between January 2016 and December 2018 and who have KNS reproduction in the blood culture. Patients were assessed by clinical and laboratory findings, risk factors for KNS, such as central catheter, and were divided into the 'confirm' and 'eventual' KNS groups and 'contamination' groups. The data was compared between groups. Results: In the study period, 40.8% of the reproductions in blood cultures (n = 130) were KNSs and the most commonly isolated species was S. epidermidis (69.2%). The rate of resistance to methyline was 77.9%. 67.7% of the fertilizations were in male babies, and 58.5% were identified as contamination. Precision KNS infection; middle pregnancy age 32 (28-34) weeks and average birth weight 1547.5 ± 446.9 grams in premature, possible KNS infection; observed in newborns over 35 weeks. The average birth weight was estimated at 3347 ± 472.5 grams of term in newborns. The most widely observed clinical findings during the KNS infection were curcumin marmoratus, vomiting, nutritional intolerance and western distinction. Compared to the possible KNS and contamination group in the specific KNS group, the CRP increase difference was significant compared to the contamination group in the potential KNS group. The other laboratory parameters in the groups were similar. Results:The pregnancy age of newborns, birth weight, the presence of risk factors for KNS, clinical and laboratory findings help in managing KNS reproductions in the blood culture.
