Background: Candida species are the most prevalent cause of invasive fungal infections such as candidemia. Candidemia is a lethal fungal infection among immunocompromised patients worldwide. Main pathogen is Candida albicans but a global shift in epidemiology toward non-albicans species have reported. Species identification is imperative for good management of candidemia as a fatal infection. The aim of the study is to identify Candida spp. obtained from candidemia and determination of mortality rate among this population.Materials and Methods: The study was performed during February 2014 to March 2015 in Tehran, Iran. Two-hundred and four blood cultures were evaluated for fungal bloodstream infection. Identification of isolates was carried out using phenotypic tests and polymerase chain reaction sequencing technique.Results: Twenty-two out of 204 patients (10.8%) had candidemia. Candida parapsilosis was the most prevalent species (45.4%), followed by C. albicans (31.8%) and Candida glabrata (22.7%). Male to female sex ratio was 8/14.Conclusions: The emergence of resistant strains of Candida species should be considered by physicians to decrease the mortality of this fatal fungal infection by appropriate treatment
