Nepal is a developing country, where there is more craziness increasing day by day in the field of microbiology.Microbes are remarkably diverse organisms. They live in habitats throughout the world: in fresh and salt water, on land, in the air, and on or inside other organisms. we can see smiley... Read More
In this blog post, I describe how I use the commonly available pGLO plasmid to teach freshman students basic concepts about transformation, receptor recognition, drug resistance mechanisms, and gene regulation. Oh, and fluorescence via GFP! Read More
The tropical disease malaria is caused by the Plasmodium parasite. For its survival and propagation, Plasmodium requires a protein called actin. Scientists of the Helmholtz Centre for Infection Research (HZI) in Germany used high-resolution structural biology methods to investigate the different... Read More
This week’s virology question comes from Eric, who writes:
I’m working on an MPH and in one of my classes we are currently studying the influenza virus. I’d forgotten that the genome is in 8 separate parts. Curious, I’ve been searching but can’t find any information as to why that is?
What... Read More
Throughout the animal kingdom, mothers transfer microbes to their young while giving birth. Different species of tadpoles acquire specific skin bacteria from mother frogs even though they all live in the same pond with the same bacterial background. Emerging chicken eggs get inoculated with micr... Read More
It has been proposed that rotavirus infection promotes the progression of genetically-predisposed children to type 1 diabetes, a chronic autoimmune disease marked by infiltration of activated lymphocytes into pancreatic islets. Non-obese diabetic (NOD) mice provide a model for the human disease.... Read More
Say what you will about our other vices, human beings did not invent cheating. Microbes have been doing it for billions of years. You see, for microbes, cheating can sometimes be an evolutionary advantage. And this can cause it to get out of hand really quickly.

Antibiotics improve growth in children at risk of undernourishment in low and middle income countries, according to researchers at McGill University who have just conducted a research literature review on the subject. Their results, published in the British Medical Journal, suggest that the youn... Read More
Newly published research shows that the use of antibacterial soaps can reduce the spread of harmful bacteria - that often leads to foodborne illness - more effectively than using non-antibacterial soaps. The research, published in the peer-reviewed Journal of Food Protection, used new laboratory... Read More
You may have heard that dollar bills harbor trace amounts of drugs. But those greenbacks in your wallet are hiding far more than cocaine and the flu. They're teeming with life. Each dollar bill carries about 3,000 types of bacteria on its surface, scientists have found. Most are harmless. But ca... Read More
A new genetic analysis revealing the previously unknown biodiversity and distribution of thousands of fungi in North America might also reveal a previously underappreciated contributor to climate change. Pine forests are chock full of wild animals and plant life, but there's an invisible machine... Read More
Over a number of years, epidemiological studies established several well-defined risk factors for cancer, including age, heredity, diet, tobacco use, chronic viral infections, and inflammation. Paradoxically, the success of these studies left little room for incorporation of any new factors or c... Read More
Methane-producing microbes may be responsible for the largest mass extinction in Earth’s history.
Evidence left at the crime scene is abundant and global: Fossil remains show that sometime around 252 million years ago, about 90 percent of all species on Earth were suddenly wiped out — by far ... Read More
Colorectal cancer develops in what is probably the most complex environment in the human body, a place where human cells cohabitate with a colony of approximately 10 trillion bacteria, most of which are unknown. At the 2014 American Association for Cancer Research Annual Meeting in San Diego, re... Read More
An antibiotic-resistant "superbug," long a problem in health-care settings, is now taking up residence in people's homes, a new U.S. study finds. Methicillin-resistant Staphylococcus aureus, commonly referred to as MRSA, was once mainly confined to places like hospitals and nursing homes, where ... Read More
Easter in the United States has become a holiday pretty much about high fructose corn syrup. To that end, here is a description of "Peep Science," using those sugary creatures that inhabit this time of year. In addition is a video that links "Peep Science" and microbiology! Read More
Partial isolate of an unknown organism on trypticase soy agar exhibiting spreading and an irregular-rhizoid form with lobate margins. The pigment is opaque white-beige with a mucoid surface over most of the colony. A dry, dull, matte surface appears toward the outer edges of the colony. The s... Read More
Partial isolate of an unknown organism on trypticase soy agar exhibiting spreading and mounding in an irregular-rhizoid form with lobate margins. The colony exhibited an opaque yellow-orange pigment with a mucoid surface. This sample was obtained from a floor swab and incubated at 37°C. Read More
Corralling desperados with names like bacillus and paenibacillus will require ingenuity and an arsenal of weapons. These outlaws aren't rustling cattle—they're making milk sour and cheese soft and crumbly.
For more than a century, milk has been heated to kill any bacteria or pathogens that ca... Read More
The video shows an ant that is infected with a fungus called Ophiocordyceps unilateralis, which has both infiltrated and commandeered its body. While it devours the ant alive, it also sends its zombified host scurrying up a plant stem. The ant walks along the underside of a leaf and vigorously l... Read More
