The typical Escherichia coli, the laboratory rat of microbiology, is a tiny 1-2 thousandths of a millimeter long. Now, by blocking cell division, two researchers at Concordia University in Montreal have grown E. coli that stretch three quarters of a millimeter. That's up to 750 times their norma... Read More
Sexual biology may be the key to uncovering why Anopheles mosquitoes are unique in their ability to transmit malaria to humans, according to researchers at Harvard T. H. Chan School of Public Health and University of Perugia, Italy. Through analysis of 16 Anopheles genomes, they found that these... Read More
I liked the discussion of the interaction of bacteria and Leishmania in sandfly guts; it was very interesting! Here is another suggestion if you need a topic to discuss:
Delivery of a functional anti-trypanoso... Read More
In a basement laboratory at the University of Pennsylvania, two roboticists have harnessed the innate sensing, swimming, and swarming abilities of bacteria to power microscopic robots. Even though their work sounds like the prologue to a dark science fiction film, Ph.D. students Elizabeth Beatti... Read More
Although natural selection is often thought of as a force that determines the adaptation of replicating organisms to their environment, Harvard researchers have found that selection also occurs at the level of neurons, which are post-mitotic cells, and plays a critical role in the emergence of A...

The slide was prepared from blood of infected animals (cattle). The smear was stained with poly-chrome methylene blue which demonstrated blue colored bacillary body and light pink colored capsule (McFadyean's reaction).
The animal had the symptoms of high fever, convulsion and sudden death. ... Read More
Saudi Arabia has not done enough to investigate and control a deadly new MERS virus that has killed hundreds of people there and remains in many ways a mystery, United Nations health experts said on Monday.
Cases of Middle East Respiratory Syndrome (MERS) are surging again, but Saudi health o... Read More

We, as most animals, host many different beneficial bacteria. Being beneficial to the host often pays off for the bacteria, as success of the host determines the survival and spread of the microbe. But if bacteria grow too much they may become deadly. In a new study published in the latest editi... Read More
Tiny parasitic hookworms infect nearly half a billion people worldwide, almost exclusively in developing countries. Researchers say sequencing the genome of a particular species could help develop more effective drugs.
Other hookworm species cause more disease among humans, but Ancylostoma ce... Read More
In one of the most comprehensive analyses of immune function performed to date, researchers analyzed blood samples from 105 sets of healthy twins. They measured immune cell populations and their chemical messengers—204 parameters in all—before and after participants received a flu shot. Differen... Read More
Emulsifiers, which are added to most processed foods to aid texture and extend shelf life, can alter the gut microbiota composition and localization to induce intestinal inflammation that promotes the development of inflammatory bowel disease and metabolic syndrome, new research shows.

When Terrance Williams was 21, he met a man in Syracuse, and the two became friends. Some weeks later, they became sexually involved. Williams and this partner—who, in court papers, is referred to only as “the victim”—used protection in their relationship, at first. But one night, Williams’s par... Read More
Plants and Microorganisms are the major sources of drugs till date. Most of these "natural products" come from a few genera of soil and marine bacteria that have long been known for their prolific chemistry. The classical process of discovering drugs from microorganisms have two drawbacks- it is... Read More
Because viruses must bind to cell surface molecules to initiate replication, the use of soluble receptors to block virus infection has long been an attractive therapeutic option. Soluble receptors have been developed that block infection with rhinoviruses and HIV-1, but these have not been licen... Read More
Significant accumulations of polyphosphate granules have been found in three common sponge species of the Caribbean coral reef, indicating that microorganisms that live on marine sponges are pulling phosphorus out of the water to feed themselves and survive in a deep-water environment where very...

A dangerous, often deadly, type of bacteria that lives in soil and water has been released from a high-security laboratory at the Tulane National Primate Research Center in Louisiana. Officials say there is no risk to the public. Yet despite weeks of investigation by multiple federal and state a... Read More
An otherwise balanced review of selected aspects of Ebolavirus transmission falls apart when the authors hypothesize that ‘Ebola viruses have the potential to be respiratory pathogens with primary respiratory spread.’
The idea that Ebolavirus might become transmitted by the respiratory route ... Read More
President Ellen Johnson Sirleaf of Liberia on Friday urged the United States to maintain its assistance to her country as it continues to fight to recover from the Ebola outbreak, which began about one year ago.
In a meeting at the White House with President Obama, Ms. Johnson Sirleaf asked f... Read More
A potentially life-threatening gastrointestinal infection is more common than previously estimated, federal health officials reported Wednesday.
The infection, caused by a bacterium known as Clostridium difficile, or C-diff, causes nearly 500,000 illnesses in the United States each year and k... Read More
