“…However, no drug interactions have been associated with VA-C leaf extracts (Daniele et al, 2005). Therefore, VA-C leaf extracts (ethanol, methanol, and water) were investigated for their ability to inhibit the growth of three Azoles antibiotic-resistant Candida species: C. ciferrii, C. albicans, and C. tropicalis (Romald et al, 2019;Bhakshu, et al, 2016).…”

“…Colonies are typically small, round, and milky-white-or cream-coloured, and can be hard, raised, and wrinkled or smooth [13,16,25,42]. Moreover, the S. ciferrii complex can grow on SDA with 0.1% cycloheximide, SDA with olive oil overlay, or 10% NaCl [36]. After 72 h, colonies appear to be embedded into the agar with a hard texture.…”

“…On the chromogenic culture media like CHROMagar™ (Candida CHROMagar™, Paris, France), colonies also grow well, are regular round with a blue centre and white edge, and become rough with gyrus-like grooves and irregular edges in 7-day cultures [25]. The chromogenic HiCrome™ Candida Differential Agar shows dry blue-white, wrinkled colonies [36], whereas a tetrazolium reduction medium (TTZ) shows pink to white dry, rough, and wrinkled colonies. The latter on potato dextrose agar (PDA), oatmeal agar (OMA), and corn meal agar (CMA) are rough, dry, white, and wrinkled [36].…”

“…But it is only in 2019 that the first case of S. ciferrii-complex-related CSOM was identified in India. Romald et al [36] reported a case of CSOM from the aural discharge after mastoidectomy in a female immunocompetent patient, which was successfully treated with oral voriconazole and topical clotrimazole. Guo et al [25] reported the majority of S. ciferrii-complex-related CSOM from China in 2021.…”

In recent years, the incidence of fungal infections in humans has increased dramatically, accompanied by an expansion in the number of species implicated as etiological agents, especially environmental fungi never involved before in human infection. Among fungal pathogens, Candida species are the most common opportunistic fungi that can cause local and systemic infections, especially in immunocompromised individuals. Candida albicans (C. albicans) is the most common causative agent of mucosal and healthcare-associated systemic infections. However, during recent decades, there has been a worrying increase in the number of emerging multi-drug-resistant non-albicans Candida (NAC) species, i.e., C. glabrata, C. parapsilosis, C. tropicalis, C. krusei, C. auris, and C. ciferrii. In particular, Candida ciferrii, also known as Stephanoascus ciferrii or Trichomonascus ciferrii, is a heterothallic ascomycete yeast-like fungus that has received attention in recent decades as a cause of local and systemic fungal diseases. Today, the new definition of the S. ciferrii complex, which consists of S. ciferrii, Candida allociferrii, and Candida mucifera, was proposed after sequencing the 18S rRNA gene. Currently, the S. ciferrii complex is mostly associated with non-severe ear and eye infections, although a few cases of severe candidemia have been reported in immunocompromised individuals. Low susceptibility to currently available antifungal drugs is a rising concern, especially in NAC species. In this regard, a high rate of resistance to azoles and more recently also to echinocandins has emerged in the S. ciferrii complex. This review focuses on epidemiological, biological, and clinical aspects of the S. ciferrii complex, including its pathogenicity and drug resistance.
