Mosquito saliva, which is injected into the host as a mosquito probes for a blood vessel, contains a collection of chemicals which include anticoagulants to prevent blood clotting, vasodilators to keep blood vessels wide, and anesthetics to prevent us from sensing the mosquito. Saliva also conta... Read More
Many years ago, Homo sapiens mated with Neanderthals. Today a small percentage of our genome remains Neanderthal, and in a study discussed on this episode of the science show This Week in Evolution, we show that some important genes of our innate immune response - the early response against path...

Science Pirates Songs presents the Bacteria Song by New Mexico State University 2003. These animated songs are from the adventure learning game, 'Science Pirates: The Curse of Brownbeard', which guide middle school students through concepts in both science and food safety. Read More
Misdiagnosis can lead to severe consequences for patients, and is a serious clinical issue. The newly emerging Candida auris requires higher doses of antifungal medications to treat an infection than does C. albicans, highlighting the importance of proper diagnosis. Thus far, the most accurate d... Read More
As the durations of manned space missions increase, it is vitally important to understand the long-term consequences of microbial exposure on human health in closed human habitats. One mission of the Microbial Observatory Experiments on the International Space Station is to examine the traits an... Read More
Well you may ask what virus ?
and I tell you West Nile Virus ( but I want to change it to WNV ). Every year when mosquito season arrives it will bring a lot of diseases . one of them is the memory loss. you may ask how does memory loss concern WNV?
Thousands of people are liv... Read More
The anaerobic, Gram-positive Clostridium difficile is a big problem. It causes rampant diarrhea and tissue necrosis, with more than 150,000 annual cases in the United States alone. Many of the disease manifestations of C. difficile are mediated by two exotoxins that C. difficile produces: TcdA a... Read More
Just like you and me, bacteria have ‘favorite’ foods – though in the case of bacteria, 'favorite' translates to those which are energetically favorable or most accessible. Different bacteria have different preferences, based on their environments and the neighboring microbes that compete for or ... Read More
Chronic wasting disease is a prion disease of cervids (deer, elk, moose) that is potentially a threat to human health. A role for environmental prion contamination in transmission is supported by the finding that plants can take up prions from the soil and transmit them to animals. 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
Virus populations do not consist of a single member with a defined nucleic acid sequence, but are dynamic distributions of nonidentical but related members called a quasispecies (illustrated at left). While next-generation sequencing methods have the capability of describing a quasispecies, the ... Read More
The Journal of Bacteriology is celebrating its centennial this year – one hundred years of valuable scientific discoveries! To illustrate the wide variety of noteworthy results published over the years, the journal is publishing a Classic Spotlight series, in which experts in the field highlight... 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.

In recent years, researchers have learned that gut microbiota play a role in a number of human diseases, including Clostridium difficile infection, irritable bowel syndrome, Parkinson’s disease, and autism spectrum disorder. The revelations have scientists hopeful that fecal microbiota transplan... Read More
Welcome back to Dispatches from ASM Microbe! Today we’ll continue Microbe 2016 highlights of the microbiome, focusing on the non-human microbiome research being presented during the conference.
As mentioned yesterday, commencement of the National Microbiome Initiative was met with great exci... Read More
Many people have a new awareness of the disease known as amyotrophic lateral sclerosis, or ALS, thanks to the Ice Bucket Challenge initiated by the ALS Association. Fewer might know that retroviruses have been proposed to play a role in the development of the disease. Read More
Jeremy joins the TWiVeroids to tell the amazing story of how the function of the HIV-1 protein called Nef was discovered and found to promote infection by excluding the host protein SERINC from virus particles.

Scientists from the University of Queensland and a biotechnology company discovered a new class of antibiotics, which is a kind of synthetic sugar. And the new antibiotics can significantly decrease the drug resistance caused by bacteria, and kill them. These new antibiotics can be a powerful dr... Read More
The sages of TWiV explain how chronic wasting disease of cervids could be caused by spontaneous misfolding of prion protein, and the role of the membrane protein Axl in Zika virus entry into cells.

I enjoy mixing Hallowe'en with my classes. In this blog post, I show how my microbiology students do exactly that, with humor and style. In addition, my freshman writing students do the same with their course on symbioses and parasitism. Enjoy...and #HappyMicrobialHalloween! Read More
