How do we define the genetic makeup of an individual? Is it the genetic material found in each cell of that individual (that’s not entirely accurate; mutations and recombinatorial differences can lead to multiple genomes in one individual). And what about the genes carried by our microbiome? The... Read More
If the DNA sequence of a cell is like the operating system of a computer, then the smallest cellular OS has just been written. Called Syn3.0, it encodes everything needed to make a viable, autonomously replicating cell.
Mycoplasma is a genus of bacteria that are the smallest known free-living... Read More
A new study led by researchers at the University of Minnesota has found a three-way link among antibiotic use in infants, changes in the gut bacteria, and disease later in life. The imbalances in gut microbes, called dysbiosis, have been tied to infectious diseases, allergies and other autoimmun... Read More
In the United States, approximately 40,000 people die every year due to pancreatic adenocarcinoma, making it the fourth leading cause of cancer related death. Patients diagno... Read More
Sea stars are lovely marine invertebrates with a round central body connected to multiple radiating legs (photo credit). In the past year millions of sea stars in the west coast waters of North America have melted into piles of slime and ossicles. Sea star associated densovirus might be the caus... Read More
Single-celled organisms called bacterioplankton spend their lives drifting in open ocean, visible to the naked eye only en masse. But don't be fooled by their slight size: These minuscule critters play a hefty role in the carbon cycle. Heterotrophic microbes, by some estimates, process half of t... Read More
THIS IS VIBRIO CHOLERAE O1 OGAWA ISOLATED FROM HUMAN STOOL SWAB PLATED ON BILE SALT AGAR Read More
The coronavirus responsible for Middle East Respiratory Syndrome (MERS) is prevalent in camels throughout Saudi Arabia and has been around for at least 20 years, according to a study to be published in mBio®, the online open-access journal of the American Society for Microbiology.
“Our study ... Read More
Researchers have found that apoptosis, a natural process of programmed cell death, can reactivate latent herpesviruses in the dying cell. The results of their research, which could have broad clinical significance since many cancer chemotherapies cause apoptosis, was published ahead of print in ... Read More
Jason Roberts, a virologist at the Victorian Infectious Disease Reference Laboratory in Melbourne, Australia, creates three-dimensional simulations of viruses showing how the molecules that make up the capsid and genome might move in very short periods of time. I visited Jason in his laboratory ... Read More
An experimental vaccine protected 100 percent of animal models against the highly infectious and virulent bacterium, Clostridium difficile, which causes an intestinal disease that kills approximately 30,000 Americans annually. The research is published ahead of print in Infection and Immunity.

Referenced dataset of host/pathogen interactions for Borrelia burgdorferi: linked to Kegg pathway interactome analysis Read More
Popular Science has just launched a new science blogging network with 13 blogs. Among them are two that have a focus on microbiology, Under the Microscope by JA Tetro and Our Modern Plague by Brooke Borel. Each blog has an inaugural post that outlines the author's vision for future subject matte... Read More
The microbes that call the New York City subway system home are mostly harmless, but include samples of disease-causing bacteria that are resistant to drugs — and even DNA fragments associated with anthrax and Bubonic plague — according to a citywide microbiome map published today by Weill Corne...

In 2009, fish in Israel began dying in droves. And not just any fish, but the St. Peter’s fish, tilapia in the Sea of Galilee—the fish famed in the Bible for feeding the multitudes and paying the temple tax for St. Peter.
As head of the fish disease laboratory for Israel’s Ministry of Agricul... Read More
Last Fall, the great Dr. Margaret McFall-Ngai "virtually visited" my freshman writing class at the University of Puget Sound to discuss symbiosis and Microbial Supremacy with my new students. I had my students read some papers by Dr. McFall-Ngai (including the wonderful "Animals in a Microbial ... Read More
A new virus called Pithovirus sibericum has been isolated from 30,000 year old Siberian permafrost. It is the oldest DNA virus of eukaryotes ever isolated, showing that viruses can retain infectivity in nature for very long periods of time. Read More
Six new cases of Heartland virus disease have been identified in residents of Missouri and Tennessee. The cause of this disease appears to be a member of the Phlebovirus genus in the Bunyaviridae family that was first identified in 2009 and appears to be transmitted by the Lone Star tick (Amblyo...

The World Health Organization launched the first World Antibiotic Awareness week, and from November 16-22 2015 discussion centered on the emerging threat of antibiotic resistance. In this post, I will review the science behind antibiotic resistant-bacteria and how this phenomena is poised to imp... Read More
Given the extent of the Ebola virus outbreak in West Africa, transport of an infected individual to the US was bound to happen. The case is an adult who had contact with an Ebola virus-infected woman in Liberia, then traveled to Dallas. He had no symptoms before arriving in the US and therefore ... Read More
