“…Nevertheless, these microorganisms can act as opportunist pathogens, invading tissues and setting off infectious processes (10, 23). Candida albicans is considered the most prevalent and pathogenic species (27), being present in around 70% of the cases of oral infections (28). Other species are also frequently associated with the development of infections, such as Candida glabrata, Candida tropicalis, Candida parapsilosis, Candida krusei and Candida guilliermondi (31).…”

This study evaluated the in vitro susceptibility of C. albicans, C. dubliniensis, C. tropicalis and C. krusei to photodynamic therapy (PDT) induced by Photogem®and light emitted diode (LED). Suspensions of each Candida strain were treated with three photosensitizer (PS) concentrations (10, 25 and 50 mg/L) and exposed to 18, 25.5 and 37.5 J/cm2 LED light fluences (λ ~ 455 nm). Control suspensions were treated only with PS concentrations, only exposed to the LED light fluences or not exposed to LED light or PS. Sixteen experimental conditions were obtained and each condition was repeated three times. From each sample, serial dilutions were obtained and aliquots were plated on Sabouraud Dextrose Agar. After incubation of plates (37 °C for 48 hours), colonies were counted (cfu/mL) and the data were statistically analyzed by ANOVA and the Tukey test (α=0.05). Complete killing of C. albicans was observed after 18 J/cm2 in association with 50 mg/L of PS. C. dubliniensis were inactivated after 18 J/cm2 using 25 mg/L of PS. The inactivation of C. tropicalis was observed after photosensitization with 25 mg/L and subsequent illumination at 25.5 J/cm2. For C. krusei, none of the associations between PS and light resulted in complete killing of this species. PDT proved to be effective for the inactivation of C. albicans, C. dubliniensis and C. tropicalis. In addition, reduction in the viability of C. krusei was achieved with some of the PS and light associations.

“…Other species, including C. tropicalis, C. krusei, and C. stellatoidea, have also been isolated (11). C. glabrata currently ranks second or third as the causative agent of superficial (oral, esophageal, vaginal, or urinary) or systemic Candida infections, which are often nosocomial (9). This species is rarely cited as agent of CE and has been underestimated due to lack of proper identification (3,8,12).…”

Candida esophagitis (CE) is a common opportunistic infection in the immunocompromised host. C. glabrata is rarely cited as agent of CE and has been underestimated due to lack of proper identification. In this study, two cases of C. glabrata esophagitis in AIDS and chagasic patients are reported. Diagnosis of Candida species should be considered an important key for the ideal choice of antifungal therapy against this mycosis.
