Epidemiology and Antifungal Susceptibility of Candida Species causing Blood Stream Infections: An Eastern India Perspective.

INTRODUCTION

Candidemia is the fourth common cause of blood stream infection worldwide leading to increased mortality and morbidity. A paradigm shift of Candida albicans to Non-albicans candida (NAC) had led to the increase in resistance to empirically used antifungals. So, an epidemiological study and antifungal susceptibility is essential for meticulous use of antifungals.

AIMS AND

OBJECTIVES

To find out the prevalence and antifungal susceptibility of Candida species causing candidemia.

METHODS

automated blood culture done in BACTEC system followed by its identification and susceptibility testing in VITEK-2 system.

RESULTS

Non-albicans candida was isolated from 73% cases of candidemia. The commonest isolate among neonates and adults were C.krusei and C.tropicalis respectively. C.haemulonii was significantly high among adult population while C.krusei was significantly high among the neonates. 10.4% NAC isolates were resistant to amphotericin B, flucytosine resistance among 37% NAC isolates and among 44% C.albicans isolates, fluconazole resistance was found among 13% and 15% of NAC and C. albicans respectively. Echinocandins were comparatively sensitive to the candida spp.
