Background And Purpose: Plants are crucial habitats for fungus communities as they provide an appropriate physical environment for the growth and reproduction of the yeast microbiome. Varieties of pathogenic and non-pathogenic yeast could be found in trees. Although species are the most common pathogenic yeasts associated with trees, other yeasts also grow on trees and are critical to human health.

Article Synopsis
  • The study highlights a shift in Candida infections from predominantly Candida albicans to a rise in non-albicans species, particularly Candida kefyr, which shows reduced antifungal susceptibility.
  • Researchers analyzed 66 isolates of C. kefyr for enzymatic activity and biofilm formation, using various testing methods to evaluate proteinase, phospholipase, haemolysin, esterase, and caseinase activities.
  • Results showed high levels of biofilm (81.8%) and proteinase (93.9%) activities, with significant variations in enzymatic profiles between clinical and non-clinical isolates, emphasizing the need for reevaluating treatment strategies for C. kefyr infections.

Article Synopsis
  • - This study focused on creating a quicker method for diagnosing pityriasis versicolor (PV) by using molecular techniques instead of traditional culture methods, which take a long time due to specific growth needs.
  • - Skin samples were collected from patients with PV and healthy controls; a polymerase chain reaction (PCR) test was used to detect and identify species, resulting in a 92.1% detection rate.
  • - The findings showed a moderate agreement between the PCR and microscopic methods, with the PCR demonstrating decent sensitivity and specificity, making it a valuable tool for rapidly identifying difficult-to-culture species.

Systemic infections are routinely treated with amphotericin B (AMB), a highly effective antimycotic drug. However, due to severe toxicities linked to the parenteral administration of conventional micellar formulations (Fungizone®), its clinical utility is limited. Hyperbranched polyglycerols (HPGs) are multi-branched three-dimensional hydrophilic macromolecules that can be used to lessen the toxicity of AMB while also increasing its aqueous solubility.
