📢 Calling future Fulbright Fellows! 🇺🇸🍄 Join my lab at the Hebrew University of Jerusalem through Fulbright and explore the nifty (sometimes gnarly) world of fungal viruses! Seeking a U.S. postdoc in fungal pathogenesis & immunity. Details in ad. Help spread spores! #Fulbright #Postdoc #Mycology

📢 We’re recruiting! Love fungi? Join us! My lab at the Hebrew University of Jerusalem is seeking PhD students and postdocs to explore fungal pathogens, immunity, and the nifty world of mycoviruses. Study seriously cool (and occasionally gnarly) fungi with us! Details in ad. Share & spread spores!

🚨A random solution to a growing fungal threat🚨 Our work on random peptide mixtures reveals potent antifungal activity against multidrug-resistant pathogens like C. auris, with low resistance potential and strong biofilm activity. Now out in mBio! Congrats to John and Yael for the fantastic work 👏

Harnessing random peptide mixtures to combat multidrug-resistant fungal infections | mBio

The rising prevalence of invasive fungal infections, particularly among immunocompromised individuals, has become a critical public health concern. However, antifungal drug development has not kept pace with this growing need, and treatment options remain limited to a small number of drug classes. The emergence of multidrug-resistant fungal pathogens, such as Candida auris, further exacerbates this crisis by reducing the efficacy of existing therapeutics and increasing the risk of treatment failure. In this study, we evaluate the antifungal potential of FK20, a random peptide mixture (RPM) composed of L-phenylalanine and L-lysine. FK20 displays potent activity against C. auris and other clinically relevant Candida species, impairs biofilm formation, and exhibits synergy with caspofungin. Importantly, FK20 limits the emergence of resistance and demonstrates therapeutic efficacy in a murine model of systemic candidiasis. These findings establish RPMs as a promising new class of antifungals with broad-spectrum activity and clinical potential against drug-resistant fungal infections.

Our study on a mycovirus that boosts fungal virulence is now out — and beautifully covered in this Behind the Paper piece by Amariliz Rivera Huge thanks for capturing the heart of the story so thoughtfully. @natmicrobiol.nature.com rdcu.be/eB9yg

Mycoviruses steer fungal fitness

Nature Microbiology - A mycovirus drives the fitness of the lung-infecting fungus Aspergillus fumigatus under stress, helping it to survive within immune cells, and thus shaping its pathogenesis.

I thought the Aspergillus fumigatus pan-genome was pretty wild when we started this project. Aspergillus flavus said, "hold my beer..." Not only does it have a strong population structure with differences between environmental and clinical strains, only 58%of genes are conserved across the species!

Thrilled to share that the final chapter of my PhD with @rokaslab.bsky.social is now out in @natcomms.nature.com 🎉 Read it to find out how population structure impacts pathogenicity in Aspergillus flavus, a fungus that infects humans 🧪 rdcu.be/eAToj

4 years ago I was honored to host the legendary Elio Schaechter in the microbiology journal club, when he was only 93 yo... Elio told us about very peculiar microbes that travel 1 mm/sec, reside inside mitochondria, ride a microbial bus...He named my kids who also joined "micro microbiologists" RIP

🚨 Fungi + viruses + mammalian lungs? Buckle up! Our new paper in @natmicrobiol.nature.com uncovers the story of a deadly fungus and its gnarly viral hitchhiker — and how this duo may change how we diagnose & treat fungal disease 🍄🫁🚨 doi.org/10.1038/s415... ⬇️
