Poison acidified crops sanitize food and limit disease transmission while at the same time structuring the gut microbiota and thus contribute to the ecological and evolutionary success of formicine ants.
Killing their neighbors allows bacteria to steal genes, including antibiotic resistance genes, which we observed under a microscope, quantified, modeled, and predicted potentially guiding strategies to combat it.
The widespread occurrence of metabolically active streptomycetes in Odontotaenius disjunctus beetle frass may insulate their galleries against pathogenic fungal invasion through the production of diverse antimicrobial specialized metabolites.
Ggta1 deletion in mice shapes and reduces the microbiota pathogenicity and probably contributed to the natural selection of GGTA1 loss-of-function mutations in the ancestral primates that gave rise to humans.
Outer membrane vesicles serve as decoys to reduce the chance of direct polymyxin B (PMB) binding to cells, which partly explains why many clinical isolates and microbial communities can be protected against PMB treatment.
Experiments in ex-germ-free mice establish a measurable effect of colonization history on gut microbiota assembly, illuminating a potential cause for the high levels of unexplained individuality in host-associated microbial communities.
