Scientists who unlocked the genetic code of bacteria grown from a soldier who died of dysentery say it revealed a superbug that was resistant to antibiotics decades before those drugs were in common use.
The discovery sheds light on the history of antibiotic resistance, which has become a glo... Read More
Whooping cough may be evolving to outsmart the currently used vaccine, say researchers.
Analysis of strains from 2012 shows the parts of the pertussis bacterium that the vaccine primes the immune system to recognise are changing.
It may have "serious consequences" in future outbreaks, UK r... Read More
"... These results, gained with a novel method for blotting (E. M. Southern, manuscript in preparation), have also led to the identification of the Bam Hl recognition sequence". It is rather unusual to find unpublished work referred to in the abstract of a paper, to put it mildly. But this was e... Read More
This one is a bit more tricky; both Giardia and Cryptosporidium are possible. The symptoms are more those of Cryptosporidium, so that would be my semi-educated guess. Most of that education comes through you, with some help of some CDC... Read More
Microbes around us is an introductory open on line course of microbiology. Key words are: bacteria, virus, biodiversity, microbial evolution, extremophiles, microbiota, rumen, nitrogen cycle, biotechnology, industrial microbiology, biodegradation, biofuel, microbial engineering, infectious disea...

New findings show programmable biomaterials can be delivered using needle injection to induce an immune response and fight deadly diseases.
One of the reasons cancer is so deadly is that it can evade attack from the body's immune system, which allows tumors to flourish and spread. Scientists ... Read More
Scientists have captured the first detailed microscopy images of ultra-small bacteria that are believed to be about as small as life can get. The existence of ultra-small bacteria has been debated for two decades, but there hasn't been a comprehensive electron microscopy and DNA-based descriptio... Read More
The World Health Organization (WHO) announced plans on October 24 to produce millions of doses of two experimental Ebola vaccines by the end of 2015.
Hundreds of thousands of doses should be available to help affected countries before the end of June, the WHO said at the conclusion of a meeti... Read More
“She did pioneering work in genetics, but it was her husband who won a Nobel price.” So said an obituary in the British newspaper The Guardian regarding Esther Lederberg, a North American microbiologist married to Joshua Lederberg from 1946 to 1966 . Being married to and working along such a... Read More
This is our first ever recommendation of an article published outside the usual scientific venues, but after all the hype we have heard about the human microbiome we were delighted to finally read a balanced account of what the research tells us and what it does not tell us. Plus, this article w... Read More
Just as humans utilize roads and freeways to move cars and resources around our cities, fungus use fluid networks to move nutrients and nuclei through their cells. Dr. Marcus Roper of UCLA explains how these networks function with remarkable efficiency and prevent microscopic traffic jams.

As will be argued below the present definition of a prokaryote is highly unsatisfactory. To give an example: a prokaryote is "a cell or organism lacking a nucleus and other membrane-enclose organelles, usually having its DNA in a single circular molecule" (Brock, Biology of Microorganisms, 10th ...

Considered as an obsolete theory for many years, the transmission of acquired traits has returned to the forefront of debate thanks to the development of epigenetic research. In this context, a team of researchers has described how in Paramecia, mating types are transmitted from generation to ge... Read More
Scientists who work on genomics and are funded by the US National Institutes of Health (NIH) must post their data online so that others can build on the information, the agency has said in an update to its guidelines.
The change, which expands the remit of an earlier data-sharing policy, is ... Read More
A deadly disease that is wiping out salamanders in parts of Europe will inevitably reach the U.S. through the international wildlife trade unless steps are taken to halt its spread, says University of Maryland amphibian expert Karen Lips.
The recently described fungus, Batrachochytrium salama... Read More
For the past four decades the Nikon Small World competition has placed photography under the microscope, with eye-catching results. This year’s 20 finalists, announced Thursday, are no exception, zooming in on microorganisms, minerals and even electronic circuitry to find beauty hidden from the ... Read More

A music video making the rounds on YouTube entitled “One Truth,” is dedicated to all of the brave researchers, healthcare workers, and others who have put their lives on the line to save people during the recent outbreak of Ebola virus disease. Pardis Sabeti, MD, DPhil, an NIH-funded New Innovat... Read More
Microorganisms are very diverse and include all the bacteria and archaea and almost all the protozoa. They also include some members of the fungi, algae, and animals such as rotifers. Many macro animals and plants have juvenile stages which are also microorganisms. Some microbiologists also clas... Read More
An international research collaborative has determined that a promising anti-malarial compound tricks the immune system to rapidly destroy red blood cells infected with the malaria parasite but leave healthy cells unharmed. St. Jude Children’s Research Hospital scientists led the study, which ap... Read More
