Gram-negative bacteria pose a particular challenge to any enterprising phage. First the phage is met by the outer membrane (OM)—a barrier to surmount that also can be used as a convenient handgrip for adsorption. Next hazard is the nuclease-infested periplasm with its jungle of peptidoglycan. An... Read More
Viruses inspire many different types of art, but I was unaware of the number of people who make viruses out of fiber! Keep reading for some photographs of what I have found. Read More
In this blog entry, I explore how students can use their creativity to learn microbiology in innovative and often artistic ways. It makes learning more personal! Read More
Hello dear TWIM'ers!
Firstly I would like to apologize in advance for my poor English skills since my native language is Portuguese. This past few years much has been the attention towards drug resistant bacteria. I am aware that a couple of your podcast touched this subject, but a few weeks ... Read More
The novel avian H7N9 influenza virus has caused more than 130 human infections with 43 deaths in China. New research, conducted under the supervision of Kansas State University's Juergen Richt, is showing promise in helping to fight this deadly virus.
"Emergence of a novel drug-resistant H7N9... Read More
Buried deep in the mud along the banks of a remote salt lake near Yosemite National Park are colonies of bacteria with an unusual property: they breathe a toxic metal to survive. Researchers from the University of Georgia discovered the bacteria on a recent field expedition to Mono Lake in Calif... Read More
Only 148 cases of Guinea worm disease were found in the world in 2013, a 73 percent drop from the 542 cases found one year earlier, the Carter Center announced Thursday.
Along with polio, Guinea worm is one of two diseases hovering on the brink of extinction, with fewer than 1,000 cases annua... Read More
The life-threatening disease typhoid fever results from the ongoing battle between the bacterial pathogen Salmonella and the immune cells of the body. Prof. Dirk Bumann's research group at the Biozentrum of the University of Basel has now uncovered how the typhoid pathogen repeatedly manages to ... Read More
The most abundant photosynthetic organism in the world sheds countless little sacs into the oceans, which could be having a dramatic impact on marine ecosystems, according to a new study. These microbial buds contain proteins and genetic material, which may influence the growth of other marine m... Read More

It seems that nearly every day, scientists connect another medical condition to atypical gut bacteria populations. Researchers have claimed that gut bacteria play a role not just in digestive health but even in basic brain function and mental health. Certain bacteria are so clearly good for us t... Read More
Researchers at the Nanoscience Center (NSC) of University of Jyväskylä in Finland have developed a novel method to study enterovirus structures and their functions. The method will help to obtain new information on trafficking of viruses in cells and tissues as well as on the mechanisms of virus... Read More
Well, it’s here. The mosquito-borne chikungunya virus finally trekked its way into the Western Hemisphere, arrived in the Americas, and has begun infecting Caribbean mosquitoes, confirming one of the worst fears of public health officials on this side of the prime meridian. This pathogen, notori... Read More
The human microbiome, the collection of trillions of microbes living in and on the human body, is not random, and scientists believe that it plays a role in many basic life processes. As science continues to explore and better understand the role of the human microbiome. A new report from the Am... Read More
Infectious diseases like AIDS and hepatitis are never pretty. But the pathogens that cause many potentially deadly infections turn out to be absolutely beautiful when viewed under powerful microscopes.
"Nowadays scientists use X-ray crystallography and more recently by cryo-electron microscop... Read More
Microbes are essential partners in all aspects of plant physiology, but human efforts to improve plant productivity have focused solely on the plant. Due to the change in environment the pathogenic microbesare growing rapidly whcich gives the negative impact that is diseases to human, animal and... Read More
Single-celled organisms have been shown to avoid bad trading partners, build local business ties, diversify or specialize in a particular commodity, save for a rainy day, eliminate the competition and otherwise behave in ways that seem to follow market-based principles.The question, a team of sc...

Tick-borne diseases are a global health problem. Based on data from large cross-sectional surveys conducted in the U.S., the CDC increased estimates of Lyme disease incidence in 2012 from approximately 30,000 new cases to over 300,000 in 2012. In comparison, the CDC estimates roughly 56,000 annu... Read More
Two small RNAs (sRNAs) working in concert enable the deadly enterohemorrhagic Escherichia coli (EHEC) 0157:H7 to attach to and initiate infection in epithelial cells that line the digestive tract, according to a study published in mBio, the online open-access journal of the American Society for ...
