51 results about "Candida auris" patented technology

Candida auris is a species of fungus first described in 2009, which grows as yeast. It is one of the few species of the genus Candida which cause candidiasis in humans. Often, candidiasis is acquired in hospitals by patients with weakened immune systems. C. auris can cause invasive candidiasis (fungemia) in which the bloodstream, the central nervous system, and internal organs are infected. It has recently attracted increased attention because of its multiple drug resistance. Treatment is also complicated because it is easily misidentified as other Candida species. C. auris was first described after it was isolated from the ear canal of a 70-year-old Japanese woman at the Tokyo Metropolitan Geriatric Hospital in Japan in 2009. In 2011, South Korea saw its first cases of disease-causing C. auris. Reportedly, this spread across Asia and Europe, and first appeared in the U.S. in 2013. DNA analysis of four distinct but drug-resistant strains of Candida auris indicate an evolutionary divergence taking place at least 4,000 years ago, with a common leap among the four varieties into drug-resistance possibly linked to widespread azole-type antifungal use in agriculture.

Use of pyridoxatin and related analogs for control of candida auris

Fungi are prolific producers of secondary metabolites and represent a rich and relatively untapped source for novel drug leads. Numerous successful therapeutics have derived from fungi, including penicillin, cephalosporin, statins, and cyclosporin. However, many promising classes of natural product are never developed into drugs because their chemical synthesis is complex or because the native organisms that naturally produce them, do so at impractically low levels. Pyridoxatins are a class of promising anti-fungal secondary metabolites produced by several naturally occurring strains filamentous fungi. The molecules have complex structures that impede straightforward chemical synthesis or analoging to increase efficacy. The disclosure herein details novel a novel use of pyridoxatin class molecules for the treatment of Candida auris and novel methods for the biosynthesis of pyridoxatins through fermentation of engineered microbes.
