Gram stain done on S. pyogenes showing the characteristic long G+ streptococcus chains. Culture grown on blood agar for 48 hrs at 37 degree’s C. Read More
Acid Fast stain done on a mix of Staphylococcus aureus and Mycobacterium smegmatis. Carbol fuchsin was applied to the smear and set over a steaming water bath for 10 min to help penetrate the mycolic acid in the cell wall, then rinsed with acid alcohol which washes the carbol fuchsin out of al...

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...

B. cereus was grown on urea agar for 6 days at 37 degrees C to induce spore formation.
The endospore stain was done using malachite green as the primary stain and safranin as counter the stain. Malachite green was applied to the smear and set over a steaming water bath for 10 min (stain was no... Read More
Romance often sparks between colleagues, and scientists are no different. Nature profiles four super-couples who have combined love and the lab.
When physicists Claudia Felser and Stuart Parkin were introduced at a conference on applied magnetics, they felt an immediate attraction. But then, ... Read More
Scientists grew Boechera stricta plants in soil inoculated with microbes from natural B. stricta habitats to study the flowering time phenotype.
The technique researchers employed to isolate soil microbes to study their effect on a single plant phenotype can potentially be applied to other st... Read More
A diagnostic tool that’s about the size of a credit card has identified a highly prized gut microbe.
The microbe contains interesting genetic sequences, but it has proven challenging to culture in the lab.
Researchers used the device, called SlipChip, to isolate microbes from a patient’s g... Read More
The burger patty that slides off the plate, the ice cream treat that plops on the picnic table, the hot dog that rolls off the grill – conventional wisdom has it that you have five seconds to pick it up before it is contaminated.
Fact or folklore?
“A dropped item is immediately contaminate... Read More
The calorie free sweetener erythritol is widely used in Asia; it is also gaining popularity in Europe and America. At the Vienna University of Technology, a new cheap method has been developed to produce erythritol from straw with the help of mould fungi.
Erythritol has many great advantages:... Read More
A virus not known to cause disease kills triple-negative breast cancer cells and killed tumors grown from these cells in mice, according to Penn State College of Medicine researchers. Understanding how the virus kills cancer may lead to new treatments for breast cancer.
Adeno-associated virus... Read More
Using two yeasts that have been used to brew tea and beer for centuries, researchers at Fred Hutchinson Cancer Research Center have revealed how reproductive barriers might rapidly arise to create species boundaries. Schizosaccharomyces pombe has been used to brew beer in Africa, whereas its clo... Read More
As many patients know, treating wounds has become far more sophisticated than sewing stitches and applying gauze, but dressings still have shortcomings. Now scientists are reporting the next step in the evolution of wound treatment with a material that leads to faster healing than existing comme... Read More
Microbiology World is a bi-monthly e-magazine, which publish articles based on Microbiology and related fields of Life Sciences. Microbiology World has been established in 2013 and has been supported by several organizations.
I, editor in chief of this magazine, would be glad... Read More
Tannery tanning fluid sample stained with Live/Dead BacLight under UV light. Either 40x or 100x oil immersion. Green bacteria indicate living cells, while Orange bacteria indicate dead cells. Some of the green cells were moving around even after staining! Read More
In the hunt for early life, geobiologists seek evidence of ancient microbes in the form of trace fossils – geological records of biological activity – embedded in lavas beneath the ocean floor. Filamentous titanite (a calcium titanium silicate mineral) microtextures found in 3.45 billion-year-ol... Read More
Bacteria in a drop of water spontaneously form a bi-directional vortex, with bacteria near the center of the drop swimming in the opposite direction of bacteria swimming near the edge. New computer simulations, confirmed by a novel experiment, explain how that vortex comes to be.

Scientists at the University at Buffalo are turning to an old class of antibiotics to fight new superbugs resistant to modern medicine.
A $4.4 million grant from the National Institutes of Health will allow UB researchers to develop new dosing regimens for polymyxin antibiotics.
Developed ... Read More
People who get bitten by a blacklegged tick have a higher-than-expected chance of being exposed to more than one pathogen at the same time.
The new research, published online today in the journal PLOS ONE, was conducted by scientists at Bard College, Sarah Lawrence College, and the Cary Insti... Read More
Many pathogenic bacteria use special secretion systems to deliver toxic proteins into host cells. LMU researchers have determined the structure of a crucial part of one of these systems – which are possible targets for novel antibiotics.
