High-resolution Staphylococcus profiling reveals intra-species diversity in a single skin niche

The skin microbiome is dominated by a few key genera, among which Staphylococcus is one of the most well characterized. Recent studies have examined the roles of various Staphylococcus species such as...

Day 7, Share. Inoviruses are filamentous single stranded DNA phages that can be produced continuously and exported by their host without lysis and killing their host. They have a single repeating major coat protein that covers their length and specialised spike proteins. #Drawtober #SciArt #Phagesky

Black and white ink drawing of two long filamentous phages. The one in the background is all the same distance away. In the foreground is a close up of the spike proteins of the closer phage with 5 repeated protein complexes forming what looks almost like a flower, the rest of the inovirus loops around into the background

Day 5, Moon. The physical structures of phages are often compared to the shape and landing action of a lunar lander, with tail fibres reminiscent of the landing struts, to gently settle on the surface of its host. #Drawtober #SciArt #Phagesky

Black and white ink drawing of the moon, with a giant phage on the top right that is half the width of the moon. The moon and phage are white, surrounded by a black circular background of messy, overlapping concentric circles

Turns out CRISPR is rarely beneficial against virulent phages, being most beneficial against those for which resistance mutations are rare!

It’s World #Sepsis Day
Sepsis kills 11 million people each year.

Symptoms incl.:
🔸Fever or shivering
🔸Confusion
🔸Shortness of breath
🔸Rash that does not fade when pressed
🔸Extreme discomfort
🔸Sweaty skin

Seek medical care as soon as possible when an infection is not getting better.

What is sepsis?
Sepsis arises when a person has an infection, and the body's reaction to it injures tissues and organs
