Helicobacter is a Gram-negative rod with a helical shape on gram stain. The most known strain is H. pylori, which causes ulcers and chronic gastritis and is said to affect up to 50% of the human population. This particular strain, Helicobacter fennelliae is most commonly found in the feces an... Read More
The time before the symptoms of a viral infection appear is called the incubation period. During this time, viral genomes are replicating and the host is responding, producing cytokines such as interferon that can have global effects, leading to the classical symptoms of an acute infection (e.g....

I took these combined pictures after growing S. aureus ST151 and ST3028 on blood agar plates. Both strains were isolated from cases of subclinical mastitis The plates were incubated at 37 C for 24 or 48 hrs as shown in the picture. ST3028 is one of the novel strains recently identified in ou... Read More
Rapid detection of antibiotic resistance is vital in assessing the appropriate antibiotic therapy for an infection. Participants will present data on two new inex... Read More
In 1976, a group of health workers took a pair of film cameras to what was then known as Zaire and documented their discovery of a new, deadly virus.
Today we know that virus as Ebola.
A 27-year-old Belgian microbiologist named Peter Piot and his colleagues were the first to scientifically... Read More
Modern biology has attained deep knowledge of how cells work, but the mechanisms by which cellular structures assemble and grow to the right size largely remain a mystery. Now, researchers may have found the key in a dynamic agglomeration of molecules inside cells.

A group of fungi growing on the surface of stagnant black tea left open to the environment. I've found this leads to beautiful morphologies when I try it. Read More
Sputum specimen from sick of fibrosis cystic can hold many microbes and yeast. This specimen sent to our laboratory Mycobacteriology of Polyclinic University of Messina for mycobacteria research, shows yeast cells with Ziehl-Neelsen stain. Read More
Did you know that you have bacterial friends that are keeping you healthy? Let the Science ACEs give you a quick introduction on the microbiome and its implications for healthcare. This is our submission for the ASM Global Video Challenge 2015! Read More

Engineered E. coli can store long-term memories of chemical exposure, other events in their DNA.
MIT engineers have transformed the genome of the bacterium E. coli into a long-term storage device for memory. They envision that this stable, erasable, and easy-to-retrieve memory will be well su... Read More
As the focus of the Ebola issue shifts from management to recovery and prevention, an array of post-infection effects have cropped up in survivors of the virus. Vision and hearing problems have resulted from infection with the Ebola virus, and researchers are now faced with the task of determin... Read More
A report in Biology Letters shows that the drool of herbivores might help defeat the toxic fungal defences of the plants they graze on.
Grazing or cutting some plants induces a noxious chemical to be produced which deters hungry plant-eaters from revisiting them. The chemicals, called alkaloi... Read More
The arrival in the United States of a Liberian man infected with the Ebola virus shows how easily the disease can travel and how thin the procedures are, relying heavily on the honesty of travelers and the diligence of airport workers. Some experts say that the system, given its inherent weaknes... Read More

Your gut is a genius. Inside it exists an astonishing ecosystem of trillions of micro-organisms—more than 10 times the number of human cells in our bodies! This ecosystem of microbes—the human gut microbiota—deeply influences our phy... Read More
When scientists launch a spacecraft into space, they're also launching thousands of bacteria along with it.
This article was originally published in the January 2015 issue of Popular Science.
To prepare the Curiosity rover for its trip to Mars, NASA scrubbed it with alcohol and baked it at... Read More
In the not too distant future each of us will be able to colonize our gut with genetically modified “smart” bacteria that detect and stamp out disease at the earliest possible moment. This scenario may sound like the premise for a sci-fi flick, but it is a very real possibility. Microbiome engin... Read More
This episode: Genes taken from bacteria may have been important for the evolution of distinct groups of archaea!

A chemist at Washington University in St. Louis is studying siderophores, iron chelating molecules released by bacteria during an infection, with the thought of using them to design personalized antibiotic therapy that would avoid the rapid evolution of resistance that plagues antibiotic drug di...
