Swab taken from the lab table top and incubated on TSA for 48 hrs, left at room temperature for 72 hrs then held at refrigerated temperature for a month. Pictured is one of the resulting fungal growths: white with no spore formation, droplets can be seen as possible result of respiration. Read More
While isolating organisms growing in a water system a dark Fungal growth was noted. I love isolating fungi and staining them in a manner that produces contrast among the hyphae. This fungi is yet to be identified but through the lense of a microscope it looks comparable to a tree in the fall a... Read More
Thank you to everyone who created a log phase masterpiece, to our esteemed judges, and to everyone who voted for People's Choice on Facebook! We received 117 amazing entries from 26 countries and 17 U.S. states. Special congratulations to our winners! View this year’s winners... Read More
The image of Red Lord Ganesha on this MacConkey agar plate is made of Serratia marcescens. It is just an expression that microorganisms are ubiquitous and miraculous in nature just as our gods.
Serratia marcescens produces a blood red pigment called prodigiosin (latin word prodigiosus meaning ... Read More
The leading infectious cause of severe respiratory disease in infants, respiratory syncytial virus (RSV), is also a major cause of respiratory illness in the elderly. Approved vaccines do not yet exist, and despite the development of partial immunity following infection during childhood, individ... Read More
This artwork is made from Escherechia coli in Mac Conkey Agar ( MCA ) and shows the other side of the biggest Buddhist temple in Indonesia and Southeast Asia built by the Syailendra dynasty called “Borobudur”, that included one of the wonders of the world from Indonesia.
With the Zika virus spreading toward the United States, threatening pregnant mothers and the 2016 Olympics, aid workers have placed hope in a familiar fish.
In the wake of Hurricane Katrina, the Virginia-based non-profit Operation Blessing helped avert an outbreak of the West Nile virus in Ne... Read More
Researchers at University of California, San Diego School of Medicine have received a five-year, $9.5-million award from the National Institute of Allergy and Infectious Diseases at the National Institutes of Health (NIH) to establish an interdisciplinary center to define the systems biology of ...

A near-atomic level map of Zika virus shows its structure to be largely similar to that of dengue virus and other flaviviruses, but with a notable difference in one key surface protein, report scientists funded by the National Institute of Allergy and Infectious Diseases (NIAID), part of the Nat...

Several weeks ago we perfected a plaque assay for Zika virus, based on our existing assays for enteroviruses. Shown is a photograph of two plates stained with crystal virolet with clearly delineated plaques. The cells are Vero and the Zika virus strain is MR766, an African isolate. Anyone intere... Read More
Researchers at the University of California, Berkeley, who have discovered more than 1,000 new types of bacteria and Archaea over the past 15 years lurking in Earth's nooks and crannies, have dramatically rejiggered the tree to account for these microscopic new life forms. Read More
As reported in a new study in the the journal Proceedings of Royal Society B: Biological Sciences, scientists have taken a step toward identifying the genetic mechanisms that makes some lowland leopard frogs in Arizona resistant to Batrachochrytrium dendrobatridis (Bd) infections that cause the ...

Engineers have developed a rapid, low-cost genetic test for Zika. The $2 device, about the size of a soda can, doesn’t require electricity or technical expertise and only needs a bit of saliva. Read More
Zika's hypothesized attraction to human neural stem cells may come from its ability to hijack a protein found on the surface of these cells, using it as an entryway to infection. In Cell Stem Cell on March 30, researchers at the University of California, San Francisco show that the AXL surface r... Read More
Viruses have proven to be wily foes. Attempts to fend off viruses that cause the common cold or flu have failed, and new viral outbreaks such as dengue, Ebola, or Zika continue to elude drugs.
Given these challenges, scientists are tackling the problem from a different angle. The want to boos... Read More
I enjoy having my microbiology students explore their creativity in interesting ways. One approach is to have my micronauts "paint" on Petri dishes using luminous bacteria. In the past, I have inviting people to "vote" on their favorites, and hand out microbiologically themed gifts. This has ... Read More
I had my #Bio350 micronauts write one page "Nanobiographies" of their #MicrobialTermPapers. I'm very pleased. 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...

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
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
