Scientists have identified the gene used by some infectious bacteria to breach defensive natural products produced by plants.
Plants are able to protect themselves from most bacteria, but some bacteria are able to breach their defences.
"Microbes only become pathogens when they find a way ... Read More

Hazel Barton, Ph.D of Northern Kentucky University explains that microorganisms actually form the basis of nearly all the ecosystems that you will find in a cave. Read More
What is a vaccine, and why do we need them? How do vaccines work, and how were they developed? In this lesson, students gauge their previous knowledge about vaccines. They then explore the history and biology of vaccines and create educational posters on the nature of vaccines and public opinion... Read More
Leaking septic systems or manure from adjacent rural properties are the two most common sources of fecal contamination of a well. The University of Wisconsin Water Resources Institute is funding a new research project to refine a methodology to determine the source of well water contamination.

Infectious diseases researchers at Umeå University in Sweden are studying the surface properties of bacteria together with materials scientists. Studies of the outermost parts of the cell walls of bacteria yield new information about the chemical composition of structures that are important for ... Read More
Every villain has his Achilles heel. And microscopic scoundrels are no exception. The challenge for those who wish to ward off microbial bad guys is to identify that weak spot. Now, scientists studying the toxoplasmosis parasite think they’ve done just that. They share the secret in the Proceedi... Read More
New findings on how tuberculosis (TB) bacteria develop multi-drug tolerance point to ways TB infections might be cured more quickly. The results identify both a mechanism and a potential therapy for drug tolerance that is induced in the TB bacteria by the host cells they infect.
The study wil... Read More
A research team from the University of Valencia has discovered that up to 20% of spices and 26% of herbs sold in Spain are contaminated by various bacteria, reducing their quality. The study, which is the first of its kind in Spain, suggests that health and hygiene control systems should be put ... Read More
Nobody’s going to shed a tear for an oiled microbe, but the Deepwater Horizon’s impacts include bacteria, underscoring just how subtle and fundamental the blowout’s ecological consequences may be.
The findings, based on comparisons of microbial flux before and after oil washed ashore, are not... Read More
Fecal bacteria — that is, germs from poop — can be found on 72% of shopping carts, MSNBC reports.
It’s yet another icky finding from University of Arizona microbiologist Charles Gerba, PhD, sometimes called “Dr. Germ.”
In his latest report, Gerba reportedly found traces of fecal bacteria o... Read More
A pioneering treatment to thwart HIV by genetically altering blood cells so the virus cannot invade them has shown promise in the first nine people to receive it.
The treatment involves taking the white blood cells most prone to infection by HIV, called CD4+ cells, from someone with HIV. Thes... Read More

Dear Vincent and Dickson:
I am retired (40 years in computers) and so I have lots of time to study
An electron photomicrograph of two spiral-shaped Treponema pallidum bacteria.
Here we see two Treponema pallidum bacteria scanned by an electron microscope, magnified 36,000X. T. pallidum is the causative agent of syphilis. It contains one of the smallest prokaryotic genomes consisting of abo... Read More
Ben-Yehuda's group identified a previously uncharacterized type of bacterial communication mediated by nanotubes that bridge neighboring cells. The researchers showed that these nanotubes connect bacteria of the same and different species. Via these tubes, bacteria are able to exchange small mol... Read More
Two official investigations have begun into an unpublished study from the 1940s in which a US researcher deliberately infected Guatemalan prisoners and soldiers with syphilis and gonorrhoea.
Both were ordered last November by President Barack Obama after the study came to light through invest... Read More
This diagrams, as a trophozoite, the various forms that the developing malarial parasite undergoes prior to its schizont stage.
As the parasite increases in size, the ring morphology of the early trophozoite disappears, and becomes what is referred to as a mature trophozoite, which undergoes ... Read More
If it's just us in this universe, what a terrible waste of space. For thousands of years, humans have wondered about who and what might be living beyond the confines of our planet: gods, beneficent or angry; a heaven full of sinners long forgiven; creatures as large and strange as our imaginatio...
