The bacteria that cause the life-threatening disease cholera may initiate infection by coordinating a wave of mass shapeshifting that allows them to more effectively penetrate the intestines of their unwitting victims, according to a study led by Princeton University.
The researchers discover... Read More
After decades of research and countless control attempts, dengue fever--a mosquito-borne viral disease--continues to infect an estimated 390 million people around the world each year. Now, researchers have reported in PLOS Neglected Tropical Diseases that the mosquitos that carry dengue virus (D... Read More
To find an effective vaccine against malaria it is crucial to test candidate vaccines on larger groups of people than previously thought - according to a new study published in PLOS Computational Biology. The researchers from Erasmus MC Rotterdam and Radboud University Medical Center Nijmegen de... Read More
Mosquitos carrying a greater number of malaria-causing parasites may be more likely to cause infection in the people they bite, according to a new study published in PLOS Pathogens.
More than 100 years have passed since scientists first discovered that infectious mosquitos inject malaria-caus... Read More
Vincent, Michael, and Michele explain the use of an electrochemical gradient to eliminate bacterial biofilms, and how phage susceptibility can be transferred by exchange of receptor proteins.
Greetings TWiM Team
Thinking about the revised estimates for the number of bacterial and human cells in the body from 10:1 to about 1:1, I was wondering what the microbiome cell to self cells ratio is for different species.
I pr... Read More
When Kaci Hickox, a Doctors Without Borders nurse, returned to New Jersey from working with Ebola patients in West Africa in 2014, she was surprised by her reception. Instead of a quiet return to her home in Maine after four weeks on the front line of Ebola treatment, she was quarantined by the ... Read More
The mention of Zika can strike fear in the hearts of pregnant women. With infections increasing around the world, including in the US, researchers are fighting the clock to figure out how the virus can have such horrific effects in some people. Read More

As we shake off the holidays, 2017 brings a new opportunity for personal reflection. For many trainees, it is also a great time to focus one’s professional goals, including those related to microbiology and microscopy. In celebration of the new year, I’d like to reflect on some of the advanced m... Read More
It was a peer review request that got Alessia Ruggieri and her group at University of Heidelberg to look more closely at how Dengue virus manipulates the cellular translation and stress machineries during infection.
In a previous study, Ruggieri showed that Hepatitis C virus infection induced... Read More
Candida albicans has the ability to form hyphae. When given space on a YPD agar plate, it can spread to take up that space. This organism was inoculated on the surface in a streak and, after an initial incubation at 30C, was incubated at 25C for three weeks. The appearance of the C. albicans as ... Read More

"What is the best way to test for Trichomonas vaginalis in a cost effective manner? It's a classic trade-off between money and assay sensitivity." Read More
The TWiV academia discuss induction of diarrhea by the capsid protein of an astrovirus, and association of a fungal RNA virus with white-nose syndrome of North American bats.
Food microbiology is an important issue we cover on this blog, because food safety is vital to prevent foodborne illness. The use of technologies like whole-genome sequencing help identify and pinpoint the source of microbial contaminants, but how do microbes become contaminants in the first pla... Read More
Some microbes can form memories—although, inconveniently for scientists who study the process, they don’t do it very often.
Rockefeller University researchers and their colleagues at the University of California, Berkeley, have found a way to make bacteria encode memories much more frequently... Read More
El sistema CRISPR, su descubrimiento y posibles applicaciones: En el episodio de hoy contamos con la presencia del Dr. Francisco Mojica de la Universidad de Alicante.
Aprovechamos una visita suya a la Universidad de Puerto Rico para poder compartir la trayectoria de uno de... Read More
If you are lucky enough to be still alive and working in 2050... How might the clinical microbiology laboratory have changed by that time? Nobody can accurately predict the future, but here are my personal thoughts... Read More
The hamlet of Resolute Bay is a tiny Arctic village in the Nunavut territory of Canada with a population that hovers at or below 300. Over hundreds of perhaps even thousands of years, the traditional Inuit diet in Resolute Bay and elsewhere has been dictated by the Arctic environment. The diet i... Read More
