"This is a fantastic video, it's about the relatively recent and vital discovery of the importance of biofilm, that green slime on the surface of mudflats.
It seems that this substance is invaluable to migrating waders and, in this case, particularly to the delightful Western Sandpiper, a declining species. The video highlights their reliance on this food source for their very survival. Without it, they would be malnourished, meaning most would not be able to complete their migration and many would simply die. This would cause a decline in the population since, as a species. they would not be able to breed in sufficient numbers to maintain the population, which ultimately could lead to their extinction. Roberts Bank in British Columbia, Canada is a globally classified Important Bird Area and a key stopover for Western Sandpipers. Distressingly, its mudflats and their biofilm covering, are threatened by the proposed expansion of the Fraser Port Authority, the so-called Roberts Bank T-2 development. If allowed to go ahead this would mean additional significant habitat loss that would further endanger the species. This situation typifies a wider crisis affecting waders across the planet, highlighting the urgent need for collaboration among researchers, conservationists, and communities to protect these vital ecosystems, and the species that use them, which are becoming increasingly at risk of extinction."

The bacterial species in subgingival plaque can be grouped into 5 major complexes. The red complex (Porphyromonas gingivalis, Treponema denticola, Tannerella forsythia) is closely tied to periodontal disease severity (pocket depth, bleeding). These findings highlight the role of sequential microbial colonization in shaping pathogenic ecosystems.

I love that the first section heading in this piece is not "Introduction" but "Imagine"

'Physics is the focus of this perspective. However, rather than describing isolated physical phenomena we form a link between physics and biology by asking how certain classes of physical processes occurring in biofilms drive their development, shape their morphology, maintain homeostasis, and regulate their response to environmental stresses.'

@cmkobel @oveoyas But wouldn't the microbe-microbe interactions within the host already be part of the #omics data?

Certainly finding the #species producing a particular protein/transcript would be very difficult (heck, even classifying microbial species is tricky given widespread horizontal gene transfer), so analyzing such data would be very hard.

Or were you talking about microbe-microbe interactions outside of a host, such as those in a multi-species #biofilm on a surface (for example)?

The biophysical basis of bacterial colony growth nature.com/articles/s41567-024

"the fitness of a biofilm—its ability to grow, expand, and absorb nutrients—is largely impacted by the contact angle that the biofilm's edge makes with the substrate... this geometry has a bigger influence on fitness than anything else, including the rate at which the cells can reproduce. That was a big surprise"

A Whiff of #Taxonomy – Altiarchaeum hamiconexum

"within its #biofilm... Individual coccoid cells are rather distant from each other. Yet they are connected by thin cellular appendages... the constant structure and size of these appendages define the distance between cells. The three-dimensional reconstruction of the appendage reveals a remarkable hook structure"

"accounts for roughly 0.1% of the microbiome—a term that includes not only bacteria and fungi but also the archaea, viruses, and parasites that colonize our skin, gut, respiratory tract, and urogenital tract. While scientists have documented hundreds of fungal species in human guts, only a few dozen are common across individuals" nationalgeographic.com/premium re: #mycobiome #biofilm #dysbiosis et al. via #natgeo
