Antibiotic Susceptibility Test (AST) Disc in Blood sample

I am sunil pandey from kathmandu Nepal, studying B.Sc in medical microbiology at nobel college. this is AST disc in MHA from blood sample, shows the clear zone of inhibition(Kirby -Bauer disc diffusion Method). I have done this experiment as part of my study "susceptibility of antibiotics in ba... Read More

Footage From 1976 Documents Discovery of Ebola Virus

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

Divide and Conquer: novel trick helps rare pathogen infect healthy people

New research into a rare pathogen has shown how a unique evolutionary trait allows it to infect even the healthiest of hosts through a smart solution to the body’s immune response against it.

Scientists at the University of Birmingham have explained how a particular strain of a fungus, Crypto... Read More

Staph ‘gangs’ share nutrients during infection: study

Antibiotic-resistant bacteria can share resources to cause chronic infections, Vanderbilt investigators have discovered. Like the individual members of a gang who might be relatively harmless alone, they turn deadly when they get together with their “friends.”

The findings, reported Oct. 8 in... Read More

Cells' powerhouses were once energy parasites: Study upends current theories of how mitochondria began

Parasitic bacteria were the first cousins of the mitochondria that power cells in animals and plants -- and first acted as energy parasites in those cells before becoming beneficial, according to a new study.

Amphibian communities collapse in wake of viral outbreak

Two closely related viruses that have been introduced to northern Spain in recent years have already led to the collapse of three different species of amphibian -- the common midwife toad, the common toad, and the alpine newt -- in the protected area of Picos de Europa National Park. In all, six... Read More

Primitive microbes stole bacterial genes on a surprising scale

A University of Otago researcher is part of an international team that has discovered that horizontal gene transfer (HGT) played a surprisingly large role in the evolution of primitive microbes known as archaea.

HGT, which involves acquiring genetic material from another unrelated organism in... Read More

Fine Reading: Trans-kingdom Cross Talk – Small RNAs on the Move

We have lived with the discovery of small RNAs as regulatory molecules for nearly 30 years, so for most readers of this blog this is old hat. But some of us oldsters are still reeling from the novelty and importance of the findings. It seems odd that a subject of this significance, one that has ... Read More

Bio-art: The Marriage of Art and Microorganisms

A short interview with artist Selin Balci on her use of microbes as an artistic medium. Here's a quote from the piece on SkyLife.com...

"Bio-art has not yet been defined in a way that is accepted by artists. Some artists, for example, make DNA models and call that BioArt. To me, BioArt has to... Read More

Scientists Discover First ‘Virological Penicillin’

Chinese researchers have discovered what they say is the first ‘virological penicillin’ – MIR2911, a molecule found naturally in a Chinese herb called honeysuckle.

Honeysuckle (Lonicera japonica) is a well-known Chinese herb. In Traditional Chinese Medicine, it has been used to effectively tr... Read More

Gelatin Hydrolysis

Pseudomonas aeruginosa, Escherichia coli and Serratia marcescens were inoculated into gelatin agar using the stab method and incubated for 1 week at 37 degree’s C. If the organism has gelatinase then it can break down the gelatin (protein) into polypeptides and then amino acids which can then ... Read More

Rats and Their Alarming Bugs

If the past few years have taught us anything, it’s that our well-being is intimately linked to the health of animals.

The current Ebola epidemic probably got its start when someone came into contact with an infected animal, perhaps a monkey or a fruit bat. The virus causing Middle East respi... Read More

CDC Launches Ebola Response Team

In the two days since the second U.S. Ebola patient was diagnosed, the U.S. Centers for Disease Control and Prevention (CDC) has assembled a new team to battle the threat of Ebola. This team has no steady lineup, but it will be deployed anywhere in the country that sees a new case of Ebola, CDC ... Read More

Study reveals how deadly MERS virus enters human cells

Cornell researchers have uncovered details of how the deadly Middle East respiratory syndrome coronavirus (MERS-CoV) enters host cells, findings that help explain how it can infect many cell types – a hallmark of viral pathogenicity. The results also offer possible new avenues for treatment.
