Deep cutaneous infection in a patient recovering from toxic epidermal necrolysis.

Med Mycol Case Rep 2019 Mar 26;23:26-28. Epub 2018 Oct 26.

Brooke Army Medical Center, 3551 Roger Brooke Drive, San Antonio, TX, USA.

Patients with toxic epidermal necrolysis, a condition that causes full thickness epidermal necrosis that affects over 30% of the skin surface and mucosal membranes, often develop comorbid infections throughout the recovery of the disease [1]. While most commonly these are related to a bacterial source, infections due to viral, mycobacterial, and rarely fungal organisms occur. We present a case of a patient who developed a deep cutaneous fungal infection caused by Trichosporon asahii and discuss the management. Read More

Mycoses 2018 Sep 19. Epub 2018 Sep 19.

Division of Infectious Diseases, Department of Internal Medicine, National Taiwan University Hospital and College of Medicine, Taipei, Taiwan.

Background: Current guidelines recommend echinocandins as first-line therapy for candidemia. However, several non-Candida yeast are non-susceptible to echinocandins (echinocandin non-susceptible yeast, ENSY), including Cryptococcus, Geotrichum, Malassezia, Pseudozyma, Rhodotorula, Saprochaete, Sporobolomyces and Trichosporon. In laboratories that are not equipped with rapid diagnostic tools, it often takes several days to identify yeast, and this may lead to inappropriate presumptive use of echinocandins in patients with ENSY fungemia.

VTT Technical Research Centre of Finland Ltd., Espoo, Finland.

Mitochondrial pyruvate dehydrogenase (PDH) is important in the production of lipids in oleaginous yeast, but other yeast may bypass the mitochondria (PDH bypass), converting pyruvate in the cytosol to acetaldehyde, then acetate and acetyl CoA which is further converted to lipids. Using a metabolic model based on the oleaginous yeast , we found that introduction of this bypass to an oleaginous yeast should result in enhanced yield of triacylglycerol (TAG) on substrate.

Samples were collected from a sequencing batch reactor (SBR) to characterize the similarities and differences in microbial community composition in samples using Illumina high-throughput sequencing. The main objective of this study was to characterize changes in microbial community composition during filamentous sludge bulking and control processes. The SBR working volume was 11 L, and the reactors were operated for 399 days in total. Read More

Converting lignin derived phenolic aldehydes into microbial lipid by Trichosporon cutaneum.

J Biotechnol 2018 Sep 18;281:81-86. Epub 2018 Jun 18.

State Key Laboratory of Bioreactor Engineering, East China University of Science and Technology, 130 Meilong Road, Shanghai 200237, China. Electronic address:

Lignin is one of the major components of lignocellulose biomass and chemically degrades into phenolic aldehydes including 4-hydroxybenzaldehyde, vanillin, and syringaldehyde. No lipid accumulation from the phenolic aldehydes by oleaginous microbes had been succeeded. Compared with vanillin and syringaldehyde, T. Read More

Getting the Jump on the Development of Bullfrog Oil Microemulsions: a Nanocarrier for Amphotericin B Intended for Antifungal Treatment.

AAPS PharmSciTech 2018 Jun 18. Epub 2018 Jun 18.

Graduate Program in Pharmaceutical Sciences, Dispersed Systems Laboratory (LaSid), Federal University of Rio Grande do Norte (UFRN), Rua General Gustavo Cordeiro de Faria, S/N, Natal, RN, 59012-570, Brazil.

Amphotericin B (AmB), a potent antifungal drug, presents physicochemical characteristics that impair the development of suitable dosage forms. In order to overcome the AmB insolubility, several lipid carriers such as microemulsions have been developed. In this context, the bullfrog oil stands out as an eligible oily phase component, since its cholesterol composition may favor the AmB incorporation. Read More

Lipase-mediated direct in situ ring-opening polymerization of ε-caprolactone formed by a chemo-enzymatic method.

J Biotechnol 2018 Sep 21;281:74-80. Epub 2018 Jun 21.

Department of Pharmaceutics, College of Chemical Engineering, Qingdao University of Science and Technology, 53 Zhengzhou Road, Qingdao 266042, China. Electronic address:

A novel method to synthesize poly(ε-caprolactone) (PCL) through a three-step, lipase-mediated chemo-enzymatic reaction from cyclohexanone using an immobilized lipase from Trichosporon laibacchii (T. laibacchii) CBS5791 was developed. The immobilized preparation with 1280 U· g used here was obtained by a method of purification and in situ immobilization where the crude intracellular lipase (cell homogenate) was subjected to partial purification by an aqueous two-phase system (ATPS) consisting of 12% (w/w) polyethylene glycol (PEG) 4000 and 13% (w/w) potassium phosphate (KHPO) and then in situ immobilization directly on diatomite from the top PEG-rich phase of ATPS.

A Polysaccharide Derived from a Trichosporon sp. Culture Strongly Primes Plant Resistance to Viruses.

Mol Plant Microbe Interact 2018 Dec 3;31(12):1257-1270. Epub 2018 Oct 3.

1 Agricultural Biotechnology Research Center, Academia Sinica, Taipei 11529, Taiwan; and.

Plant viruses cause devastating diseases in plants, yet no effective viricide is available for agricultural application. We screened cultured filtrates derived from various soil microorganisms cultured in vegetable broth that enhanced plant viral resistance. A cultured filtrate, designated F8 culture filtrate, derived from a fungus belonging to the genus Trichosporon, induced strong resistance to various viruses on different plants. Read More

Multiple sclerosis and mixed microbial infections. Direct identification of fungi and bacteria in nervous tissue.

Neurobiol Dis 2018 Sep 1;117:42-61. Epub 2018 Jun 1.

Centro de Biología Molecular "Severo Ochoa" (CSIC-UAM), c/Nicolás Cabrera, 1. Universidad Autónoma de Madrid, Cantoblanco, 28049 Madrid, Spain. Electronic address:

Multiple sclerosis (MS) is the prototypical inflammatory disease of the central nervous system (CNS), leading to multifocal demyelination and neurodegeneration. The etiology of this incurable disease is unknown and remains a matter of intensive research. The possibility that microbial infections, such as viruses or bacteria, can trigger an autoimmune reaction in CNS tissue has been suggested. Read More
