Cultivation of Candida tropicalis IBEM 303 without thermostatic regulation on n-alkanes results in an increase of the temperature in the fermenter to supraoptimal values and to the linear growth of the culture without distinct differentiation according to the growth phases. The cells grown at supraoptimal temperature differ from the cells cultivated at optimal temperature by the amount of some amino acids and oligopeptides liberated by the yeast into the cultural broth, by the chemical composition of the cells and their morphology.

Background: Tropical Candida spondylitis is an uncommon cause of lower back pain in patients, especially in non-tropical areas or in patients not at risk of immunocompromise.
Case Presentation: A 65-year-old woman presented with a six-month history of poorly managed low back pain, now accompanied by numbness and pain in both lower extremities. Her medical history was significant for tertiary hypertension.
Anidulafungin is a useful surrogate marker for predicting susceptibility to rezafungin among five species using CLSI methods and interpretive criteria.

This study addresses the use of other echinocandins as surrogate markers to predict the susceptibility of rezafungin against the six most common spp. The Clinical Laboratory Standards Institute (CLSI) reference broth microdilution method was performed to test 5,720 clinical isolates of six different species. Species-specific interpretative criteria by CLSI breakpoints or epidemiological cutoff values were applied.

Candida is a commensal fungus of clinical interest that commonly lives in oral cavity and intestine but can become an opportunist microrganism and cause severe infections. A serie of 10 aminochalcones were designed and synthetized to obtain compounds anti-Candida with potent and broad-spectrum activity. The most active compound J34 demonstrated excellent in vitro activity against Candida albicans, Candida tropicalis, Candida parapsilosis, Candida glabrata and Candida krusei with minimum inhibitory concentration between 1.

Fermented milk products (FMP) have been consumed by humans for millennia and the health benefits are no longer to be demonstrated. Although the manufacturing procedure have been industrialized, FMPs are still produced traditionally in many parts of the world with variable manufacturing procedures and unknown sanitary conditions. In this study, we aimed at comparing the physico-chemical properties of industrial and traditional FMPs from France and Mali as well as their microbial diversity.
