			Phylogenies of Pathogenic Microorganisms Phylogenies show how organisms are related to each other by placing them in an ordered map of them and their relatives. These can be done on a large scale, such as the tree of life, or on a smaller scale, such as showing all the species of Mycobacterium bacteria. When done on microorganisms, phylogenies can provide valuable insight into how diseases evolve, spread, and adapt to their hosts.

			Is There a Link Between Migraine and the Gut Microbiome? The intestine is in constant communication with the brain, and the gut microbiome is an important contributor in this.

	Microbiome DNA signature present in human fetal lungs The lungs and placentas of fetuses in the womb -- as young as 11 weeks after conception -- already show a bacterial microbiome signature, which suggests that bacteria may colonize the lungs well before birth.

	Scientists modify a toxic protein to create a biosensor Some types of bacteria kill other cells by releasing proteins called “pore-forming toxins” (PFTs) that create holes in the cell membrane. The PFTs bind to the cell membrane and burrow into, creating a tube-like channel or pore. Once enough holes have been punched into the cell membrane by these toxins, the target cell destroys itself.

	New paper-based test for early Lyme diagnosis A new paper in the journal ACS Nano reports the development of an incredibly cheap and highly sensitive test to diagnose Lyme disease in its earliest stages, when it can be most easily, effectively and inexpensively treated.

	Mechanisms behind antibiotic resistance captured on video for the first time In a world-first, scientists have established the cause of antibiotic-resistance in bacteria, capturing video footage showing that bacteria have the ability to change their form in order to avoid detection by antibiotics.
