Sorry for the delayed post, WordPress was playing some mean tricks on me today and there were no treats! Good morning all and happy spooky season! It’s been a moment since I’ve written a post and I write to you now as a freshly (pepper)minted PhD! I’m feeling gourd and can’t wait to pumpkin spice things up with some fangtastic papers.

Some of the highlights include a paper by McAlpine et al. examining interkingdom relationships between bacteria and fungi. Specifically, they found that the gut commensal species Lactobacillus can produce a small molecule that blocks filamentous growth of the opportunistic pathogen Candida albicans. Another interesting paper comes from Michael Adams lab at the University of Georgia, Athens which showed that members of the gut microbiota have the capacity to assimilate the metal tungsten which, in turn, allows these microbes to oxidize a broad range of aldehydes in the gut. Additionally, a paper by Plummer et al. looked at the vaginal microbiota of women who have recurrent bacterial vaginosis as well as the penile microbiota of their partners, and found that when males also underwent antibiotic treatment it led to a decrease in bacterial vaginosis in their female partners.

Hope you enjoy reading these fa-boo-lous papers and may you eat, drink, and be scary this Halloween!
