Objective To study the clinical characteristic and antifungal drug sensitivity of neonatal Candida parapsilosis infections in blood and to provide reference for clinical prevention and therapy.Methods The drug resistance of Candida parapsilosis which were isolated from 8 neonatal blood specimen on the laboratory were analyzed and clinical characteristic of infections in neonates were investigated retrospectively.The blood cultured with BD9120.The fungi were isolated with Sabourand Dextrose Agar and CHROMagar colored medium and identified with API20C.The susceptibility test was then performed with FUNGUS3 micro dilution plate.Results Candida parapsilosis susceptibility results to antifungal drugs showed that 5-flucytosine≤ 4 μg/ml,amphotericin B ≤ 0.5 μg/ml,fluconazole ≤ 1 ～ 2.0 μg/ml,itraconazole ≤ 0.125 ～0.125 μg/ml,voriconazole ≤0.06 ～0.06 μg/ml.Seven cases were preterm infants(low birth weight infants or extremely low birth weight infants),one case was term infant after operation of congenital pyloric atresia.Before blood culture,all the 8 cases of Candida parapsilosis sepsis had received broad-spectrum antibiotics and intravenous nutrition.All the 8 cases had received peripherally inserted central catheter,and 3 cases had received mechanical ventilation.Four cases with fluconazole,3 cases with fluconazole and amphotericin B,1 case with fluconazole at the onset but changed VFend,all 8 cases were cured.Conclusion Candida parapsilosis has become the one of the main pathogens of neonatal infection fungal in blood of premature or low birth weight infants,which is sensitive to 5 kinds of antifungal drugs in vitro susceptibility test.Early detection and antifungal therapy can improve the prognosis.
