Most Candida infections are related to microbial biofilms often formed by the association of different species. The objective of this study was to evaluate the interactions between Candida albicans and non-albicans species in biofilms formed in vitro. The non-albicans species studied were:Candida tropicalis, Candida glabrata and Candida krusei. Single and mixed biofilms (formed by clinical isolates of C. albicans and non-albicans species) were developed from standardized suspensions of each strain (10(7) cells/mL), on flat-bottom 96-well microtiter plates for 48 hour. These biofilms were analyzed by counting colony-forming units (CFU/mL) in Candida HiChrome agar and by determining cell viability, using the XTT 2,3-bis (2-methoxy-4-nitro-5-sulphophenyl)-5-[(phenylamino) carbonyl]-2H-tetrazolium hydroxide colorimetric assay. The results for both the CFU/mL count and the XTT colorimetric assay showed that all the species studied were capable of forming high levels of in vitro biofilm. The number of CFU/mL and the metabolic activity of C. albicans were reduced in mixed biofilms with non-albicans species, as compared with a single C. albicans biofilm. Among the species tested, C. krusei exerted the highest inhibitory action against C. albicans. In conclusion, C. albicans established antagonistic interactions with non-albicans Candida species in mixed biofilms.

Fungal periprosthetic joint infections (PJIs) are rare but increasingly recognized complications following total joint arthroplasty (TJA). While remains the most common pathogen, non-albicans species and other fungi, such as , have gained prominence. These infections often present with subtle clinical features and affect patients with significant comorbidities or immunosuppression.

Background: Vulvovaginal candidiasis and urinary tract infections caused by are common diseases. While the most common causative agent is , other species, such as non-, can also be responsible. Susceptibility to antifungal drugs varies among species, but there is very limited information available from Vietnam.

Psittaciformes kept as pets can serve as reservoirs of various microorganisms, many of which have zoonotic potential, including spp. In this study, the antifungal susceptibility profiles of 16 spp. isolated from the oral and cloacal cavities of 20 pet parrots were evaluated.

Currently, the rising prevalence of resistant species, particularly , as well as non-albicans isolates such as and , represent challenges in their management. In this review, we aimed to explore the current management of fluconazole-resistant vulvovaginal candidiasis (FRVVC). Identified studies focused on alternative antifungal therapies, including boric acid, nystatin, and newer agents like oteseconazole and ibrexafungerp.

Background And Purpose: infections in India have shifted, with an increase in the incidence rate of invasive candidiasis, particularly due to non- species. The central nervous system infections by are sparsely reported and more understanding and research is needed regarding these infections.
Case Report: This study reported an unusual case of meningitis in a middle-aged female with pulmonary tuberculosis and newly diagnosed acquired immunodeficiency syndrome with a low cluster of differentiation 4 count (12 cells/mm).
