The most common candidiasis is caused by Candida albicans; however, Candida dubliniensis has become an emerging opportunistic pathogen, and although less prevalent, it can cause superficial and systemic infections, especially in immunocompromised individuals. This yeast can colonize the oral cavity, skin, and other tissues, and has been associated with oral infections in patients with human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS), making it difficult to treat. The special interest in the study of this species lies in its ability to evade commonly used antifungal drugs, such as fluconazole, under different concentrations. In addition, it is difficult to identify because it can be confused with the species C. albicans, which could interfere with adequate treatment. Although the study of virulence factors in C. dubliniensis is limited, proteomic comparisons with C. albicans indicate that these virulence factors could be similar between the two species. However, differences could exist considering the evolutionary processes and lifestyle of each species. In this study, a detailed review of the current literature on C. dubliniensis was conducted, considering aspects such as biology, possible virulence factors, immune response, pathogen–host interaction, diagnosis, and treatment.Keywords: candidiasis, emerging pathogens, host–fungus interaction, non-albicans species, virulence factors
