A towering figure in microbiology, our friend Fred Neidhardt died on October 7, 2016 at his retirement home, the Academy Village near Tucson AZ. He made fundamental and abiding contributions to research, teaching, academic administration, and social issues. In each, he left deep-rooted mar... Read More
Happy bacteria couple drawn on TSA plate using a MRSA culture.
This picture illustrates how happy bacteria can become when people don't take all the antibiotic treatment correctly. Antibiotic resistance is a big problem nowadays. Read More
A device used during open-heart surgery that infected at least 12 patients at a Pennsylvania hospital last year was probably tainted at the plant in Germany where it was made, a federal investigation has found.
The device, called a heater-cooler machine, uses water to regulate the temperature... Read More
The oxidase test is performed using a reducing agent to detect bacteria’s ability to produce cytochrome c oxidase, an enzyme in the electron transport chain. The reducing agent (N,N,N′,N′-tetramethyl-p-phenylenediamine (TMPD)) changes or produces a purple color as it become oxidized. Pseudom... Read More
A new microscopic technique is enabling scientists to observe the antibiotic daptomycine live in action. This marks an exciting first, because even though doctors have been prescribing this antibiotic for over a decade, its precise mechanisms have remained unclear.
First, the scientists tagg... Read More
Daniel Haeusser, an Assistant Professor in the Biology Department of Canisius College in Buffalo, New York, discusses the misconception of assuming that photosynthesis exists as single process of strict coupling between energy conversion and carbohydrate production. Read More
U.S. public health officials are bracing for a wave of babies with severe Zika-related birth defects. The latest official numbers suggest 808 pregnant women in the U.S. appear to have been infected with Zika. Yet doctors are also steeling themselves for the possibility of birth abnormalities in ...

A single season of intense melting buffeted Antarctica in 2001-2002. It yielded changes that ranged from speeding up microbial food webs to shifting penguin populations. A special section in the October issue of BioScience examines the impacts on two very different Antarctic ecosystems.

Cranial neural crest cells--which give rise to the bones and cartilage of the skull--are vulnerable to Zika virus, report Stanford University School of Medicine researchers September 29 in Cell Host & Microbe. The discovery, made by infecting in vitro cultures of human cells, offers a potential ... Read More
Organisms that have the catalase enzyme can detoxify the cell of hydrogen peroxide by converting it to oxygen gas. Bubbles indicate oxygen gas production after the addition of hydrogen peroxide directly to colonies growing on the TSA plate.
For the past several decades, farmers have been abandoning their plows in favor of a practice known as no-till agriculture. Today, about one-third of U.S. farmers are no longer tilling their fields, and still more are practicing conservation tillage—using equipment that only disturbs the soil to... Read More
Florida announced a new Zika transmission zone on Thursday, saying that the virus had popped up in a mile-square patch of northern Miami and that five people had been infected.
The area, around the Little Haiti neighborhood, goes from NW 79th Street in the north to NW 63rd Street in the south... Read More
Advancing Partners & Communities is excited to launch part one of a two-part compelling, original video series showcasing the work in Sierra Leone to improve primary health care services at health posts and community levels. This first video focuses on the efforts needed to rebuild these service... Read More
A specific strain of the fungus, Fusarium oxysporum, circulates in the water distribution systems of five French hospitals, in two widely separated cities. This microbe is potentially a life-threatening risk to immunocompromised patients. The research is published September 23, 2016 in Applied a... Read More
A microbe that ‘eats’ both methane and iron: microbiologists have long suspected its existence, but were not able to find it - until now. Researchers at Radboud University and the Max Planck Institute for Marine Microbiology in Bremen discovered a microorganism that couples the reduction of iron... Read More
It is (almost boringly) obvious that cell-to-cell communication is vital in multicellular organisms. To function properly, all cells in a tissue have to know – and let their neighbors know – where exactly they are, which tasks they're performing right now, when it's time to differenti... Read More
Small regulatory RNA molecules are vital for salmonella and other bacteria potentially harmful to humans: This RNA type controls gene activity and allows bacteria to quickly adjust to changing conditions of living and stress as are typical during an infection, for example, when entering the bloo...

In a very interesting development, a latest study has debunked the belief that it was safe to eat food fallen on the floor if picked up within “five seconds”.
Professor Donald W Schaffner, a food microbiologist at Rutgers University in New Jersey, said a two-year study he led concluded that no ... Read More
The bonded carbons are shown using E. coli, E. faecalis, and C. violaceum. Using BBL's CHROMagar, we were able to show the pi bonds in pink (E. coli) and blue (E. faecalis). Read More
