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
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
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
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
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
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.

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...

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
The ultra-small bacteria were discovered in groundwater. The sample was taken from Rifle, Colorado. The cells take on the appearance of tightly-coiled spirals. The bacterial cells are thought to be the smallest that a cell can be and still hold sufficient material to sustain life.
The cells h... Read More
This is a Tease Prep stain of the Fungal Rhizopus with Lactophenol Blue. It is seen under a microscopy at total magnification of 1000x. As shown there are pseudohyphae with conidia formed around the cells. It was the first tease prep stain that clearly shows the artistry of the fungal structure.... Read More
Potentially toxic microbes which pose a threat to our drinking water have undergone a dramatic population explosion over the last 200 years as a result of pollution, research involving experts from The University of Nottingham has found. The study, published in the journal Ecology Letters, looke... Read More
A new paper-based platform has been created for conducting a wide range of complex medical diagnostics. The key development was the invention of fluid actuated valves embedded in the paper that allow for sequential manipulation of sample fluids and multiple reagents in a controlled manner to per...
