One of the most important aspects of a new laboratory protocol is its reproducibility (as previously discussed on ASM’s Microbial Sciences blog). A protocol must produce the same results when performed by different scientists at different labs, and this is especially important when considering n... Read More
If you live with pets, you know where their tongue has been, yet you let them kiss and lick you all they want without even thinking twice about it. I've heard people say that a dog's mouth is very clean, and that their saliva, delivered by licking, can help heal wounds, but is that really true?

“There are many gut microbiome studies on humans and rodents, but not a whole lot on dogs, in particular,” says Johnny Li, a computational biologist at the Nestle Purina PetCare Company, in St. Louis. He recently led a study on the connection between diet and intestinal bacteria on 64 dogs — 32 ... Read More
In this ASM Virtual Lecture Dr. James McSharry, Professor Emeritus, Albany Medical College, describes the structure of the influenza viruses, types of human influenza viruses and their replication in cells, licensed influenza drugs, current influenza vaccines, and the future of influenza vacci...

Molecular diagnosis is creeping into many areas of bacteriology, but the diagnosis of wound infection remains "stubbornly" culture based. What are the barriers to using molecular methods on wound swabs, and are there any potential solutions?... Read More
Bacteria can communicate through a system known as quorum sensing, where, for example the production of toxin in some species is not initiated until a minimum threshold of bacterial cells are present. This allows them to coordinate and therefore strengthen their actions to overcome selective pre... Read More
Viruses may be stealthy invaders, but a study at the Weizmann Institute of Science reveals a new, chatty side of some: For the first time, viruses have been found communicating with one another. This communication – short “posts” left for kin and descendants – helps the viruses reading them to d... Read More
Scientists have discovered how a unique bacterial enzyme can blunt the body’s key weapons in its fight against infection.
Researchers at the University of Illinois at Urbana-Champaign and Newcastle University in the U.K. are investigating how infectious microbes can survive attacks by the bod... Read More
The global industrial microbiology market is expected to witness a y-o-y growth of 6.7% in 2016 over 2015 and reach US$ 9.46 Bn in revenues. North America will continue to be the most lucrative market, accounting for over 25% of the market share.
In addition to increase in food consumption, r... Read More
This episode: Viruses infecting photosynthetic bacteria could transfer immunity to other viruses between their hosts!

Fungal contaminant seen on TSA after several months at refrigerated temperatures. Green spore formation can be seen with exudate droplets through out. Hyphal growth extended up the side of the dish and onto the lid. Read More
The TWiVaniellos discuss a thermostable poliovirus empty capsid vaccine, and two cell genes that act as a switch between entry and clearance of picornavirus infection.
Star Wars – an epic story of war between the forces of good and evil in a galaxy far, far away. The Death Star – the ultimate weapon of destruction. The story is science fiction, but it could be considered an analogy for the constant battle between our immune system and microbial pathogens. Beli... Read More
Scientists have identified a ‘molecular barcode’ in the blood of patients with Ebola virus disease that can predict whether they are likely to survive or die from the viral infection.
A team at the University of Liverpool, in collaboration with Public Health England, Boston University and oth... Read More
A growing body of evidence indicates that the trillions of microbes that live on and inside our bodies affect our health. Collectively, these resident microbes form our microbiome.
In a new paper appearing in the journal Cell Host & Microbe, researchers at the University of Washington report ... Read More
A family of highly drug-resistant and potentially deadly bacteria may be spreading more widely—and more stealthily—than previously thought, according to a new study from Harvard T.H. Chan School of Public Health and the Broad Institute of MIT and Harvard.
Researchers examined carbapenem resi... Read More
Before infecting humans, tick-borne bacteria or viruses first have to get past a tick’s defenses to colonize it. How this occurs is not well understood. To investigate, Yale researchers studied a model of the second-most-common tick-borne infection in the United States, human granulocytic anapla... Read More
The technique that the hepatitis E virus — an emerging liver virus historically found in developing countries but now on the rise in Europe — uses to spread could present a weak spot scientists can exploit to treat the disease, according to a new study.
Princeton University-led researchers re... Read More
The Rapid Drug Susceptibility Testing Consortium (RDST), coordinated by the Critical Path Institute (C-Path) through the Critical Path to TB Drug Regimens (CPTR) initiative, announces the public launch of the Relational Sequencing TB Data Platform (ReSeqTB). ReSeqTB is a data-sharing platform an... Read More
A generation ago, two antibiotic strategies known as cycling and mixing were employed to outwit bacteria. Cycling is like antibiotic crop rotation where certain classes of antibiotics are withdrawn for a period of time. Doctors thought this would combat resistance because bacterial pathogens wou...
