Microbial World
Microbial life is everywhere - a largely invisible world of astonishing metabolic diversity that helped to create the biosphere and that continues to support life on earth. In fact, there are more bacterial cells inside your gut and on your skin than there are cells in your entire body. So, we are not only living in a microbial world… we are microbial worlds!”


This Curation Blog aims to be a comprehensive and entertaining source of microbial news.

Small Things Considered: Sex to the Rescue | Microbial World | Scoop.it

Life is tough out there. If chemistry (via oxidizing radicals) doesn’t get you, sunlight (via UV irradiation) will. No wonder that cells, both prokaryotic and eukaryotic, have an intense preoccupation with keeping their DNA intact.

Eawag: Antibiotic resistance genes accumulating in Lake Geneva | Microbial World | Scoop.it

Large quantities of antibiotic-resistant bacteria enter the environment via municipal – and especially hospital – wastewater streams. Although wastewater treatment plants reduce the total number of bacteria, the most hazardous – multiresistant – strains appear to withstand or even to be promoted by treatment processes. This was demonstrated by Eawag researchers in a study carried out in Lake Geneva, near Lausanne.

Princeton University - 'Universal' vaccines could finally allow for wide-scale flu prevention | Microbial World | Scoop.it

An emerging class of long-lasting flu vaccines
could do more than just save people the trouble
of an annual flu shot.
Princeton University-based researchers have
found that the “universal” vaccine could for the
first time allow for the effective, wide-scale prevention
of flu by limiting the influenza virus’ ability
to spread and mutate.
