The TWiV team is together in New York City for a conversation with Nobel Laureate Harold Varmus about his remarkable career in science.
Recently, one of the Journal of Bacteriology Classic Spotlight series highlighted the numerous studies on bacterial spores that have been published in the journal throughout the years. Bacterial endospores, the resilient and relatively quiescent bacterial structures first identified in the 1800s... Read More
Have you ever gone to the beach, ready for a day of sun and sand, only to find a warning sign? One of the most common reasons beaches close is due to the presence of coliform bacteria. These indicator bacteria, such as Escherichia coli, are used as markers for fecal waste, since their presence c... Read More
No matter the niche field a scientist pursues, there is one aspect of almost all career paths that scientists have in common: teaching. Whether lecturing a quorum of undergraduates about bacterial genetics, mentoring a research fellow as they learn the lab protocols, or presenting an invited lec... Read More
Smithsonian.com delves into the weeds of horizontal gene transfers (HGT) in bacteria. A feat that is largely unique to bacteria, it allows bacteria to trade DNA with other bacteria.
Bacteria can "exchange DNA as easily as we might exchange phone numbers, money or ideas".
Explore some of ... Read More
The Gram-positive bacterium Enterococcus faecium is a member of the ESKAPE pathogens for which drug resistance has been a growing problem. How E. faecium becomes drug resistant has been a long-standing question, and is the focus of a new study now available in Antimicrobial Agents and Chemothera... Read More
Transmission of Zika virus (ZIKV) was first detected in Colombia in September 2015. As of April 2016, Colombia had reported over 65,000 cases of Zika virus disease (ZVD). We analysed daily surveillance data of ZVD cases reported to the health authorities of San Andres and Girardot, Colombia, bet... 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
This episode: Bacteria in hydrothermal vents that feed their host tubeworms evacuate when their hosts perish!
(9 MB, 9.8 minutes)
The latest Zika virus news from the ConTWiVstadors, including a case of female to male transmission, risk of infection at the 2016 summer Olympics, a DNA vaccine, antibody-dependent enhancement by dengue antibodies, and sites of replication in the placenta.
The TWiP ternion solve the case of the Man from Mexico, and discuss a transgenic toxoplasma vaccine for chickens using Eimeria tenella.
Vincent speaks with Sandy Weller about her career and her work on the mechanisms of synthesis, maturation, cleavage and packaging of viral DNA genomes.

Michael and Vincent present Spotlights, brief reviews of classic papers in the Journal of Bacteriology, and explain how a single bacterial species can reverse autism-like social deficits in the offspring of obese mice.
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
In systems biology studies, the integration of multiple omics measurements (i.e., genomics, transcriptomics, proteomics, metabolomics, and lipidomics) has been shown to provide a more complete and informative view of biological pathways. Thus, the prospect of extracting different types of molecu... Read More
If it looks like a duck and quacks like a duck, it’s likely a duck – so goes the saying that illustrates the simplest explanation is usually the right one. But what about duck decoys used in conjunction with bird calls? Misidentification can be a deadly error – and the same goes for microbes. Mi... Read More
As we highlighted in our previous blog, antibiotic stewardship – the careful use of appropriate antibiotic administration – can have positive effects. A small change from a difference in clinical lab reporting led to less drug use, which led to fewer drug-resistant infections. When we think of a... Read More
Microbial communities are essential drivers of soil functional processes such as nitrification and heterotrophic respiration. Although there is initial evidence revealing the importance of soil type in shaping microbial communities, there has been no in-depth, comprehensive survey to robustly es... Read More
There’s no way to avoid the news of a growing concern for drug-resistant infections. In both life-threatening and relatively superficial infections, the ability to successfully treat microbial infections with antimicrobials is decreasing. Our only recourse is to use the drugs we have carefully w... Read More
