Article Synopsis
  • The study investigated nikkomycin Z's effectiveness in treating central nervous system coccidioidomycosis in mice, showing significant improvements in survival and reduction of brain fungal burden compared to control.
  • Mice were given nikkomycin Z at doses of 50, 100, and 300 mg/kg three times daily, or fluconazole, starting two days post-inoculation with the fungus.
  • Nikkomycin Z targets fungal cell walls, making it a potentially safer treatment option than traditional antifungals, which can have adverse effects due to interactions with human enzymes.

Ibrexafungerp (formerly SCY-078) is the first member of the triterpenoid class that prevents the synthesis of the fungal cell wall polymer β-(1,3)-D-glucan by inhibiting the enzyme glucan synthase. We evaluated the efficacy of ibrexafungerp against pulmonary mucormycosis using an established murine model. Neutropenic mice were intratracheally infected with either or .

Candidiasis is one of the most frequent nosocomial infections affecting an increasing number of at-risk patients. remains the most frequent causative agent of candidiasis, but, in the last decade, has emerged as a formidable multi-drug-resistant pathogen. Both species are fully capable of forming biofilms, which contribute to resistance, increasing the urgency for new effective antifungal therapies.

Candida spp. are opportunistic yeasts capable of forming biofilms, which contribute to resistance, increasing the urgency for new effective antifungal therapies. Repurposing existing drugs could significantly accelerate the development of novel therapies against candidiasis.

There is increased concern that the quality, generalizability and reproducibility of biomedical research can be influenced by the sex of animals used. We studied the differences between male and female mice in response to invasive pulmonary mucormycosis including susceptibility to infection, host immune reaction and responses to antifungal therapy. We used diabetic ketoacidotic (DKA) or neutropenic mice infected with either or .
