Since caspofungin inhibits fungal cell wall beta-glucan synthesis and the fungal cell wall plays an important role in the recognition of Candida by phagocytic cells, we studied phagocytosis in the presence of caspofungin. The aim of this work was to investigate the effect of pre-treatment of Candida parapsilosis with caspofungin on phagocytic mechanisms (opsonisation, oxidative burst, phagocytosis and killing). C. parapsilosis grown in the presence of caspofungin at concentrations above the minimal inhibitory concentration (MIC) were more difficult to opsonise and to phagocytose. C. parapsilosis exposed to any concentration of caspofungin below and above the MIC was more difficult to kill. Caspofungin-treated C. parapsilosis impaired the oxidative burst. Overall, it appears that caspofungin treatment of C. parapsilosis alters the capacity of polymorphonuclear leukocytes to phagocytose and delays killing of the organism. This may allow C. parapsilosis to persist in tissues.

Background: This study assesses the impact of fluconazole resistance on 30-day all-cause mortality and 1-year recurrence in patients with Candida parapsilosis bloodstream infections (BSI).
Methods: A multicenter retrospective study was performed at 3 hospitals in Italy and Spain between 2018 and 2022. Adult patients with positive blood cultures for C.

Patients with selective IgA deficiency could have various clinical presentations ranging from asymptomatic to severe respiratory or gastrointestinal tract infection, as well as autoimmune disease and allergic reactions. Selective IgA deficiency is relatively common in Caucasians, but it is rare in the Asian population, meaning it could be easily missed in the clinic. In this study, we report a 26-year-old man with a history of asthma and nephrotic syndrome.

Oleaginous yeasts are considered promising sources for lipid production due to their ability to accumulate high levels of lipids under appropriate growth conditions. The current study aimed to isolate and identify oleaginous yeasts having superior ability to accumulate high quantities of lipids; and enhancing lipid production using response surface methodology and repeated-batch fermentation. Results revealed that, twenty marine oleaginous yeasts were isolated, and the most potent lipid producer isolate was Candida parapsilosis Y19 according to qualitative screening test using Nile-red dye.

Aspergillus and Candida are ubiquitous fungi included in the group of high priority in the World Health Organization list of fungal pathogens. They are found in various ecosystems and the environmental role in increasing the resistance to antifungals has been shown. Thus, we aimed to determine the occurrence of Aspergillus spp.

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.
