In this study, 8.10 log colony-forming unit (CFU)/mL was the highest cell viability of Paenibacillus polymyxa Kp10 at 22 h during incubation. The effects of several selected protective agents on the viability of P. polymyxa Kp10 after freeze-drying were studied. Response surface methodology (RSM) was used for optimizing formulation for the protective agents. The combination of lactose (10% w/v), skim milk (20% w/v), and sucrose (27.5% w/v) was found to be suitable for preserving P. polymyxa Kp10 during freeze-drying. Further, P. polymyxa Kp10 demonstrated the ability to inhibit fungal pathogens, Colletotrichum truncatum an...

In this study, we screened a library of 1068 FDA-approved drugs to identify hits that exhibit broad-spectrum antifungal activity. Robenidine, an anticoccidial agent which has been widely used to treat coccidian infections of poultry and rabbits, was identified in this screen. Physiological concentration of robenidine (8 μM) was able to significantly inhibit yeast cell growth, filamentation and biofilm formation of Candida albicans – the most extensively studied human fungal pathogen. Moreover, we observed a broad-spectrum antifungal activity of this compound against fluconazole resistant clinical isolates of C. al...

Cryptococcus neoformans is an opportunistic yeast that is present worldwide and interacts with various organisms. In humans, it is responsible for cryptococcosis, a deadly invasive fungal infection that represents around 220,000 cases per year worldwide. Starting from the natural history of the disease in humans, there is accumulating evidence on the capacity of this organism to enter dormancy. In response to the harsh host environment, the yeast is able to adapt dramatically and escape the vigilance of the host’s immune cells to survive. Indeed, the yeast exposed to the host takes on pleiotropic phenotypes, enabling...

​Emergency providers expeditiously sift and sort patients on their shifts and streamline procedures like how to place an ear wick in a patient with otitis externa, a quick and useful procedure for a patient who will reap the rewards.Standard ear wicks. The material is made from a dehydrated sponge composed of hydroxylated poly(vinyl acetate). It increases in size when liquid is applied. Photo by M. Roberts.Otitis externa can cause significant swelling, irritation, pruritis, and pain to the ear canal. Occasionally, the canal is so swollen it may be difficult to administer ear drops. An ear wick can be inserted between the...

Abstract Fusarium spp. has been associated with a broad spectrum of emerging infections collectively termed fusariosis. This review includes articles published between 2005 and 2018 that describe the characteristics, clinical management, incidence, and emergence of these fungal infections. Fusarium solani and F. oxysporum are globally distributed and represent the most common complexes. Few therapeutic options exist due to intrinsic resistance, especially for the treatment of invasive fusariosis. Therefore, the use of drug combinations could be an important alternative for systemic antifungal resistance. Increase in the nu...

Contributors : Sascha Kahlfuss ; Ulrike Kaufmann ; Stefan FeskeSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusImmunity to fungal infections is mediated by cells of the innate and adaptive immune system. Activation of immune cells requires Ca2+ influx through the Ca2+ channel ORAI1, which is activated by stromal interaction molecule 1 (STIM1). Th17 cells are essential for immunity to C. albicans infection and require Ca2+ influx for expression of IL-17A and other Th17 cytokines. In mice, deletion of STIM1 and thus Ca2+ influx in all immune cells enhanced susceptibility to mucosal C. a...

A 14-year-old boy who lives with his family in Paris was referred for suspected fungal infection. He was originally from Algeria, where he goes during school holidays. His last stay was in summer 2018 in which he exhibited pruritic lesions on the face, neck, thorax and arm, appeared at the end of his vacation. The clinical manifestations were extensive lesions, grew centrifugally with peripheral erythemato-scaly border and healed center. Suspected lesions on glabrous skin were sampled by scraping and swabbing.
