Recently recognized outbreaks, or clusters of MRSA in community settings have been associated with strains that have some unique microbiologic and genetic properties, compared with the traditional hospital-based MRSA strains, which suggests some biologic properties, e.g., virulence factors like ...

A new research study of the effect of a commonly used strategy to reduce the spread of antibiotic-resistant bacteria in hospital intensive care units (ICU) shows that the strategy had no significant effect. That's the surprising finding of a multisite study led by Mayo Clinic investigators. The ... Read More
Frog and toad skins already are renowned as cornucopias of hundreds of germ-fighting substances. Now a new report in ACS's Journal of Proteome Research reveals that the toad brains also may contain an abundance of antibacterial and antiviral substances that could inspire a new generation of medi...

A recent study has revealed some of the bacteria found on orthodontic retainers, worn after orthodontic treatment is completed, can be associated with the hospital superbug MRSA, a condition which can lead to blood poisoning.
The research, carried out by the UCL Eastman Dental Institute in L... Read More
In the eerie bluish-purple depths of an Antarctic lake, scientists have discovered otherworldly mounds that tell tales of the planet’s early days.
Bacteria slowly built the mounds, known as stromatolites, layer by layer on the lake bottom. The lumps, which look like oversized traffic cones, r... Read More
The human microbiota -- the communities of commensal bacteria that live in our gut, mouth, and on our skin -- have recently been hailed as a forgotten organ, and praised for the positive impact they have on our health. Recent research has suggested that the 1014 or so organisms, representing mor... Read More
What would you conclude if you read the following headlines: Man sexually transmits insect-borne disease to wife (Fox News); Zika virus: First insect borne STD? (HuffPo); Scientist gives insect-borne disease to wife during sex (New York Magazine), and A scientist contracts a mosquito-borne virus... Read More

Manuka honey could be an efficient way to clear chronically infected wounds and could even help reverse bacterial resistance to antibiotics, according to research presented at the Society for General Microbiology's Spring Conference in Harrogate.
Professor Rose Cooper from the University of W... Read More
You can't see them, or smell them or taste them. They can be in our water and in our food, multiplying so rapidly that conventional testing methods for detecting pathogens such as E.coli, Salmonella and Listeria come too late for the tens of thousands of Canadians who suffer the ill effects of t...

Bacterial genes that make urine less acidic could be good targets to prevent catheter blockage, according to research presented at the Society for General Microbiology's Spring Conference in Harrogate. The findings could lead to new strategies to prevent serious infections, particularly in long-... Read More
El podcast del Microbio Nº190 and 191 describes the recent metagenomic results that point towards the existence of a 4th do... Read More
Vaccination would help to address the current cholera epidemic in Haiti, say US researchers. They believe the measure should be deployed alongside efforts to provide clean drinking water and improved sewage treatment. At present, no such vaccination is planned. Experts disagree over whether vacc... Read More
Almost everyone knows about Escherichia coli O157:H7, the culprit behind many headline-making outbreaks of foodborne illness in the United States. But the lesser-known relatives of this pathogenic microbe are increasingly of concern to food safety scientists. Read More
This digitally-colorized scanning electron micrograph (SEM) depicted large numbers of Gram-positive Enterococcus sp. bacteria.
“Enterococci, leading causes of nosocomial bacteremia, surgical wound infection, and urinary tract infection, are becoming resistant to many and sometimes all standard ... Read More
Altering microbial enzymes can lead to more powerful drugs that are effective against bacteria resistant to traditional antibiotics.
The evolution of antibiotic-resistant bacteria has left researchers scrambling to develop new, stronger antibiotics. Now researchers have successfully used a met... Read More
Glenn Rall, a virologist at Fox Chase Cancer Center, sent me the following note:
Baruch S. Blumberg, Nobel Laureate in 1976 for discovery of Hepatitis B (and the eventual development of the vaccine, which probably has saved hundreds of thousands of lives since its introduction), died this pas... Read More
Scientists from Columbia University, Georgia Institute of Technology and the University of Granada have for the first time reconstructed active enzymes from four-billion-year-old extinct organisms. By measuring the properties of these enzymes, they can examine the conditions in which the extinct... Read More
Bacteria that grow in the antennae of wasps help ward off fungal threats by secreting a 'cocktail' of antibiotics explains a scientist at the Society for General Microbiology's Spring Conference in Harrogate. Read More
