The recent Ebola outbreak in West Africa has claimed more than 11,300 lives and starkly revealed the lack of effective options for treating or preventing the disease. Progress has been made on developing vaccines, but there is still a need for antiviral therapies to protect health care workers a... Read More
A new discovery by Arizona State University scientists shows exactly how two specific metallic elements in the right kinds of clay can kill troublesome bacteria that infect humans and animals. Read More

Unknown organism seem after washing hands on a hand print grown on TSA. Larger organism (possible Bacillus spp) is circular, edges not smooth, mucoid with rhizoid like growth towards the edges. Second smaller organism is yellow, mucoid, and has something erupting from the center. Read More
I am Bibha Dahal, Graduate Teaching Assistant from South dakota State University, Brookings, SD. I have attached the image of nitrogen fixing bacteria, with water drop like appearance, grown on Nitrogen Free Medium, incubated at 28 degree Celsius for 4 days at microaerophilic condition.
Thank ... Read More
Serratia marcencens and Corynebacterium xerosis on TSA make for a great valentine for any microbiologist! Read More
Researchers from the Institut Pasteur, Inserm, CNRS and Paris Descartes - Sorbonne Paris Cité University recently published a large-scale study in Nature Genetics based on almost 7,000 strains of Listeria monocytogenes -- the bacterium responsible for human listeriosis, a severe foodborne infect...

Having confirmed the first cases of infection in Suriname then in French Guiana, the Institut Pasteur in French Guiana has sequenced the complete genome of the Zika virus, which is responsible for an unprecedented epidemic currently sweeping through the tropical regions of the Americas. Publishe... Read More
Bacterial infection takes hold in the body when a pathogenic microorganism delivers toxins to healthy cells. One way bacteria accomplish this is by releasing vesicles, which act as tiny envelopes transporting toxins and other virulence factors to host cells. These toxins allow the bacteria to "m...

Different view of Unknown Fungal contaminant on 7.5% NaCl BHI after several month at refrigerated temperatures. White hyphae was seen spreading into the agar with no spore formation. Read More
Some kids & I have been swabbing their classroom, and this colony caught my eye, or is it two colonies living in a mutualistic relationship. Perhaps this is commensalism as the red one seems to really like the yellow one. Or perhaps it is the same colony of microbes, somehow producing two differ... Read More
Growth of Acetobacter pasteurianus on glucose, yeast extract, calcium carbonate, ethanol medium.
Formation of acetic acid from ethanol oxidation is shown by a clear halo around bacterial growth due to dissolution of calcium carbonate.
Organism: Acetobacter pasteurianus. Incubation conditions:... Read More

The genomes of two distinct strains of the virus that causes the common lip cold sore, herpes simplex virus type 1 (HSV-1), have been identified within an individual person -- an achievement that could be useful to forensic scientists for tracing a person's history. The research also opens the d... Read More

Cryptococcus cells seen with India Ink staining from CSF of an HIV patient in Tanzania. Taken using nothing more than a smartphone camera. The negatively stained capsule is clearly visible, proving that with very simple techniques and a cellphone you can get very clear images of microorganisms Read More
Microbes are hardly the poster-children of climate change, but they have far more impact than polar bears on Earth’s carbon cycle – and therefore on our climate. A new study published Friday in Science Advances finds that seabed bacteria and archaea (which look like bacteria but have very differ... Read More
SILVER SPRING, Md. - The Walter Reed Army Institute of Research (WRAIR) today announced the initiation of a Phase 2 clinical trial to evaluate the safety and immunogenicity of a prime-boost Ebola vaccine regimen in both healthy and HIV-infected study volunteers. Read More
