Researchers in the US have developed a silver nanoparticle-based paper test to simultaneously detect dengue, yellow fever and Ebola. This could provide a cheap and reliable diagnosis for all three diseases, that’s as quick as a home pregnancy test.
The test is made from strips of paper contai... Read More
Since life originated on Earth between 3.8 and 3.9 Ga ago, microorganisms have significantly shaped and influenced the chemistry of Earth’s surface and subsurface environments. Reconstructing the evolution of early microbial life depends mainly on finding organic and mineral remnants of microbia... Read More
The entry of enveloped viruses into cells begins when the membrane that surrounds these virus particles fuse with a cell membrane. The process of virus-cell fusion must be tightly regulated, to make sure it happens in the right cells. The fusion activity of measles viruses isolated from the brai... Read More
Switchgrass successfully removed up to 40 percent of the PCBs from contaminated soils in lab experiments. When a PCB-oxidizing microorganism joined in, the removal rate reached 47 percent.
The researchers investigated how adding an aerobic PCB-oxidizing microorganism could enhance the oxidati... Read More
Canned fruit is often safer than the frozen variety according to University of NSW Associate Professor Julian Cox, an expert in food microbiology.
"The heat treatment used to make canned products shelf stable in ambient temperatures is much more than sufficient to kill micro-organisms includi... Read More
According to the Review on Antimicrobial Resistance commissioned by the UK Prime Minister, failing to address the growing problem of drug-resistant infections could cause 10 million deaths a year and cost up to $100 trillion USD by 2050.
Now, researchers from the Hebrew University of Jerusal... Read More
A new study suggests that bacteria may be able to jump between host species far easier than was previously thought. Researchers discovered that a single genetic mutation in a strain of bacteria infectious to humans enables it jump species to also become infectious to rabbits. The discovery has m... Read More
Four Web-based training modules developed by Johns Hopkins Medicine for emergency department personnel who treat patients with infectious diseases are now available on the Centers for Disease Control and Prevention (CDC) website.
Titled Ebola Preparedness: Emergency Department Guidelines, the... Read More
The appearance of infectious diseases in new places and new hosts, such as West Nile virus and Ebola, is a predictable result of climate change, says a noted zoologist affiliated with the Harold W. Manter Laboratory of Parasitology at the University of Nebraska-Lincoln.
In an article publishe... Read More
A new family of bacteria that are common in malaria mosquitoes has been described by researchers at Swedish University of Agricultural Sciences (SLU) and Uppsala University in Sweden, Justus-Liebig-Universität Giessen, Germany, and the Veterinärmedizinische Universität, Austria. Now, attempts ar... Read More
It’s a firmly established fact straight from Biology 101: Traits such as eye color and height are passed from one generation to the next through the parents’ DNA.
But now, a new study in mice by researchers at Washington University School of Medicine in St. Louis has shown that the DNA of ba... Read More
New research from the University of Alabama at Birmingham suggests that Fusobacterium necrophorum more often causes severe sore throats in young adults than streptococcus — the cause of the much better known strep throat. The findings, published today in the Annals of Internal Medicine, suggest ... Read More
Pure culture of Pseudomonas sp. isolated from rain collected at Virginia Tech, USA.
Incubation Conditions: 48 hours at 28°C + 24h at 20°C on EMB Agar
It can be distinguished two types of colonies following a gradient of culture density.

To determine how long Ebola virus could remain infectious in a body after death, National Institutes of Health (NIH) scientists sampled deceased Ebola-infected monkeys and discovered the virus remained viable for at least seven days. They also detected non-infectious viral RNA for up to 70 days ... Read More
Living deep underground ain't easy. In addition to hellish temperatures and pressures, there's not a lot to eat. Which is why oil reservoirs are the microbes’ cornucopia in this hidden realm.
Microbes feast on many oil reservoirs, but it has been unclear how the micro-organisms got to those ... Read More
Fecal microbiota transplantation can be effective for recurrent Clostridium difficile infection, but new-onset obesity could follow transplant of stool from an overweight donor, a new study finds
"Fecal transplant has helped a lot of people who have run out of other options," Dr. Colleen R. K... Read More
In this short blog post, I "write" on Petri dishes with bioluminescent bacteria to create words and poems in "living light." I also write a haiku to quorum sensing in the same style! Read More
Strain: Pseudomonas aeruginosa PA14
Medium: M8 minimal medium agar plates
Incubation Conditions: 48 hours at 37°C
Pseudomonas aeruginosa is a gram-negative, rod-shaped and monoflagellated bacterium that has an incredible nutritional versatility. Swarming motility, a flagellum-dependent behavi... Read More
