Really excited to see this piece out in The Microbiologist! 🐾🦠🌍 A look at how human activities are reshaping wildlife microbiomes—and when those changes may become a One Health concern. Thanks to @amiposts.bsky.social for the opportunity to contribute!

Human activities are transforming #ecosystems, but their effects on wildlife microbiota are poorly understood. This Unsolved Mystery by @kate-lagerstrom.bsky.social &co looks at human impacts reshape host-associated #microbiota and outlines strategies for the field. 🧪 #AcademicSky plos.io/4gzWDw5
Schematic of human impacts on wildlife microbiota.
Anthropogenic activities influence host-associated microbial communities through multiple interacting pathways, three of which are highlighted here: pollution, habitat transformation, and altered host contact networks. Pollution can drive the loss of co-evolved symbionts and increase selective pressures for the emergence and spread of antimicrobial resistance (AMR). Habitat transformation reshapes microbiota by changing habitat connectivity and microbial dispersal, as well as through physiological stress and host responses, often in a species-specific manner. Arrows indicate the direction of change in microbiota diversity across host species (red = decreased, green = increased, yellow = unchanged). Altered host contact networks result from human activities that reorganize which species interact, how often they come into contact, and which microbial source pools they encounter. These altered networks can create opportunities for human–wildlife microbial exchange, cross-species transmission, and microbial establishment in new host species or populations. Solid gray lines indicate existing wildlife interactions, broken gray lines indicate disrupted interactions, and purple bidirectional arrows indicate new or intensified anthropogenic connections. Together, these pathways can alter the composition, function, and evolutionary dynamics of microbiota, with implications for host health and disease risk. Created in BioRender. Moeller, A.

If an #H5N1 pandemic starts tomorrow or in three months, there will be little mystery as to how it happened. The conditions are all there. They have been for a while. So in some ways the more interesting question to me at the moment is: Why aren’t we in a pandemic yet? Story here, 🧵 to come: 🧪#IDSky

Why hasn’t the bird flu pandemic started?
Some scientists examining mutations found in H5N1 viruses fear major outbreak is imminent but others says pathogen remains unpredictable
