Each year, 2 million people get an infection that is resistant to antibiotics, the CDC has reported. Twenty-three thousand of them die as a result of the infection, and many more die from related complications.
Carbapenem-resistant Enterobacteriaceae (CRE) are just one variety of antibiotic-r... Read More
Bad bacteria could soon have no place left to hide, thanks to new materials that turn the cell’s own defences against them.
Scientists at The University of Nottingham and GSK Consumer Healthcare have developed a technique that could locate the potential source of an infection by hijacking the... Read More
What effect does the varroa mite, and the viruses it transmits, have on bee colonies? To find out, scientists have developed a new computer model to that simulates a honey bee colony over the course of several years.
Shown in the video on this page, the BEEHAVE model was c0-funded by BBSRC and... Read More
Scientists have discovered that bacteria found in a traditional Japanese pickle can prevent flu. Could this be the next superfood?
The research, which assesses the immune-boosting powers of Lactobacillus brevis from Suguki – a pickled turnip, popular in Japan – in mice that have been exposed ... Read More
Modern archeologists, excavating ancient Egyptian tombs, have often found something unexpected amongst the tombs’ artifacts: pots of honey, thousands of years old, and yet still preserved. Through millennia, the archeologists discover, the food remains unspoiled, an unmistakable testament to the... Read More
The drug tamoxifen appears to kill a fungus associated with a deadly brain infection that afflicts HIV/AIDS patients, according to a University of Rochester study published online today by mBio, the journal of the American Society for Microbiology.

Bacitracin test done on a lawn of Streptococcus pyogenes grown on blood agar. The zone of inhibition around the bacitracin disc, approx 14mm measuring the entire length of the zone, indicates sensitivity. The zone of inhibition is red because the red blood cells did not lyse. Grown for 24 hr... Read More
Growing cells – in a laboratory in space or on earth – forms a fundamental basis of modern microbiology, supporting everything from culturing microbes to novel drug design and growing human tissues for use in research and development. The problem is that cells grown on a 2D Petri dish do not ... Read More
Thank you for the great podcast! You've explained our story very well and it was funny to listen to it. I didn't know that "Speak friend and enter" is from lord of the rings! I just wanted to explain the name CYCLOPS because this was a question mark in t... Read More
On the list of substances you really don’t want to mess with, elemental mercury is pretty high up. Inhalation or absorption of the volatile metal can quickly lead to irreversible poisoning. Unfortunately, Hg is also a hallmark of industrial society.....Mercury-resistant bacteria carry a collecti... Read More
This month the World Health Organization (WHO) will meet to decide whether or not to destroy the last living strains of the variola virus, which causes smallpox. Since the WHO declared the disease eradicated in 1979, the scientific community has debated whether or not to destroy live virus sampl... Read More
The following picture shows the isolated black colonies of Salmonella on Salmonella-Shigella (S-S) Agar. S-S Agar is used as a selective and differential medium for the isolation of Salmonella and some Shigella species. The inclusion of bile salts is to inhibit gram-positive organisms. Ferric ci...

An Auckland scientist has invented molecules that can attach themselves to any surface in a few minutes and modify every type of cell or virus. The potential for the technology is huge - from attacking cancer cells to protecting newborn babies. Read More
While genetics likely play a role in some instances of colorectal cancer, a new study in mice suggests gut bacteria could also influence development of intestinal tumors. Researchers from the Icahn School of Medicine at Mount Sinai found that giving antibiotics to mice to disrupt their microbial... Read More
In this paper we describe the perspective of following the achievements in medicine, where gut microbiome transplants are proving to be a powerful method to overcome several gastrointestinal disorders and many other physiological problems, to possible solve diseases in plants. There is strong si... Read More
The TWiVome discusses an miRNA based strategy to mitigate risk of gain of function studies, and identification of a second receptor required for Lassa virus entry.
Quorum sensing is one of the most amazing things about bacteria. More and more research is focusing on potential quorum sensing applications in biomedicine and many other fields of life sciences.
This is a video that I made about QS for a competition in my University. No previous science bac... Read More
Food-poisoning outbreaks linked to disease-causing strains of the bacterium Escherichia coli are normally associated with tainted meat products. However, between 20-30% of these are caused by people eating contaminated vegetables, as was seen in the 2011 outbreak in Europe that caused 53 deaths.... Read More
