Visceral leishmaniasis, also called kala-azar, strikes 400,000 people every year and kills around 1 in 10 of its victims. The leishmania parasite, Leishmania donovani, has proven difficult to treat, in part because a large percentage of patients who take the drug of choice, miltefosine, relapse ... Read More
A new method of imaging cells is allowing scientists to see tiny structures inside the 'control centre' of the cell for the first time.
The microscopic technique, developed by researchers at Queen Mary University of London, represents a major advance for cell biologists as it will allow them ... Read More
Artist Sonja Bäumel explores the skin microbiome in her project Cartography of the Human Body. Bacteria isolated from Bäumel’s skin were characterized and grown individually, then used to reconstruct an artificial microbiome with many layers of differently-colored species. Giant petri dishes gre... Read More
We have been using HeLa cells in my laboratory since 1982, when I arrived at Columbia University Medical Center fresh from postdoctoral work with David Baltimore at MIT. I brought with me a line of HeLa cells and used them for 30 years for our research on viruses. Here is a story of how we lost ... Read More
Working with a synthetic gene circuit designed to coax bacteria to grow in a predictable ring pattern, Duke University scientists have revealed an underappreciated contributor to natural pattern formation: time.
In a series of experiments published Oct. 8, 2013, in the journal Molecular Syste... Read More
By caging bacteria in microscopic houses, scientists at The University of Texas at Austin are studying how communities of bacteria, such as those found in the human gut and lungs, interact and develop infections.
In a recent experiment they demonstrated that a community of Staphylococcus aure... Read More
By tinkering with their chemical structures, researchers at the University of California, San Diego School of Medicine have essentially re-invented a class of popular antimicrobial drugs, restoring and in some cases, expanding or improving, their effectiveness against drug-resistant pathogens in...

Greetchen Diaz es una joven investigadora en el area de los virus del papilloma humano (HPV) que son los responsables de las verrugas, pero también aparecen como una de las causas más com... Read More
Bacterial cells use an impressive range of strategies to grow, develop and sustain themselves. Despite their tiny size, these specialized machines interact with one another in intricate ways.
In new research conducted at Arizona State University’s Biodesign Institute, Jonathan Badalamenti, Cé... Read More
A doctoral research project studying the bacterium Brucella pinnipedialis, which commonly occurs in hooded seals, found that this bacterium does not cause disease in hooded seals, as other Brucella bacteria do in other species.
The occurrence of the bacterium B. pinnipedialis in hooded seals ... Read More
Giving babies "good" bacteria may help ease incessant fussing and crying, says a fresh look at past studies.
But researchers say it's too soon to recommend the bacteria, known as probiotics, for colicky babies.
"There is some promise in probiotics, but we need further research to clarify i... Read More
On 4 July, good news arrived in the inbox of Ocorrafoo Cobange, a biologist at the Wassee Institute of Medicine in Asmara. It was the official letter of acceptance for a paper he had submitted 2 months earlier to the Journal of Natural Pharmaceuticals, describing the anticancer properties of a c... Read More
The most important zoos of the future might not house endangered lions or tigers. Instead, they could hold disease-causing bacteria.
Scientists at the University of Texas have begun 3D printing microscopic habitats to study bacterial communities. They say the tiny "cages" are better at repro... Read More
The most well-known advances in nanotechnology have led to dramatically smaller devices that provide us very fast, compact and "smart" electronics including computers, cellphones, and games. In the process we have transformed the way that we communicate with each other. Along with these advances... Read More
This episode: Slime mold cells carry bacteria with them, some for food and some for chemical warfare!
An investigational vaccine appears generally well tolerated and effective against the most common strain of norovirus, reducing the main symptoms of the gastrointestinal (GI) infection, vomiting and/or diarrhea, by 52 percent, suggests research being presented at IDWeek 2013™.
Currently, ther... Read More
A tag team of two bacteria, one of them genetically modified, has a good chance to reduce or even eliminate the deadly disease African trypanosomiasis, or sleeping sickness, researchers at Oregon State University conclude in a recent mathematical modeling study.
African trypanosomiasis, cause... Read More
The mix of bacteria in the vagina changes as women go through menopause. And a certain mix is typical after menopause in women who have vulvovaginal atrophy (VVA), a common cause of vaginal dryness and sexual pain, finds a team at Johns Hopkins and the University of Maryland. They suspect these ... Read More
A universal infant vaccination campaign in China has led the Hepatitis B virus (HBV) to more than double its rate of "breakout" mutations. These mutations may enable the virus to elude the vaccine, necessitating new vaccination strategies. Researchers at the Chinese Centers for Disease Control a... Read More
