Metabolomics and feeding experiments demonstrate the host’s active role in sharing organic acids with a gut microbiota member, revealing host–microbe interactions that foster symbiosis.
Sensing of brain glucose by the fungal pathogen Cryptococcus neoformans alters lipid metabolism and membrane composition in the fungus, rendering it drug tolerant.
Cases of Buruli ulcer in southeastern Australia have increased over the past 10 years. Native possums are a reservoir for Mycobacterium ulcerans (the cause of Buruli ulcer), but the route of transmission to humans is unclear. Our findings identify mosquitoes as the vector of M. ulcerans from possums to humans.
The antimicrobial agent epifadin, which is produced by the nasal commensal Staphylococcus epidermidis, has— despite its short half-life — broad-spectrum activity, including against Staphylococcus aureus.
Bacteroides fragilis employs two different mechanisms, secreted microbe- and host-targeting toxins, that facilitate successful colonization of the mammalian gastrointestinal tract.
