Just heard TWIM 67 -- excellent of course -- and recalled, like Elio, being in basic training in the 60's when meningitis cases occurred on the base and we had to sleep with all the barracks windows open. I think we were double-bunked but can't recall if w... Read More
Breastfeeding until at least nine months of age increases prevalence in the gastrointestinal tract of Lactobacilli and Bifidobacteria, species which are known to contribute to development of a healthy immune system, according to a paper describing the establishment of the intestinal microbiota d...

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
Imagine going to the doctor with an infection and being sent home with a course of drugs. Unknown to your doctor you actually have two infections. If you take the drugs will the other infection go away by itself? What if you take the drugs and the other infection gets worse? This quandary faces ... Read More
Greetings Vincent and Dick,
Hooray for finally mentioning G. pulchrum in episode 62, my most favorite parasite and one worthy of further discussion. As a diagnostic veterinary pathologist, I encounter this spirurid in approximately... Read More
Sherlock Holmes was as much a scientist as a detective. Maybe that’s because his creator, Arthur Conan Doyle, was influenced by a detective of science: Robert Koch, a German doctor who helped prove the existence of germs. In his new book, The Remedy, Thomas Goetz traces connections between the t... Read More
A diagnostic tool that’s about the size of a credit card has identified a highly prized gut microbe.
The microbe contains interesting genetic sequences, but it has proven challenging to culture in the lab.
Researchers used the device, called SlipChip, to isolate microbes from a patient’s g... Read More
A study led by St. Jude Children’s Research Hospital scientists highlights a new approach for developing a universal influenza vaccine that could protect against multiple flu strains, including deadly pandemic strains. The research appears today in the advance online edition of the scientific jo... Read More
One in every three bottlenose dolphin tested in the Indian River Lagoon on Florida's Atlantic coast has antibodies to a bacteria that can make them more vulnerable to other deadly infections, according to a new study.
The finding comes as researchers struggle to figure out what has caused a r... Read More
Like humans, mice start life with sterile lungs that soon get colonized by microbes, which appear to protect the lung tissue from an asthma-like reaction in the presence of dust mites.
Human cells are outnumbered ten-to-one by the microbes that thrive in and on us. Now a study finds that the ... 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
When antibiotics first started being used in the 1940's they were considered a "miracle drug". It seemed that bacterial infections would no longer be a problem for the world. However, recently, one gene is making it seem as though the end of antibiotics is at hand. This gene is New Delhi metallo... Read More
Research on bacterial movement tends to focus on the rod-shaped bacteria. With the aid of small waving flagella, each bacterial cell can push itself in the direction it wishes to go. They can also move in groups, forming large swarms that ripple and slide their way across Petri dishes. Spherical... Read More
Neisseria meningitidis may cause septicemia (bacteria in the blood) and meningitis (infection of the membrane surrounding the brain), but the bacterium colonizes the nasopharynx in 10-20% of the human population without causing disease. Although understanding how the bacterium changes from a com... Read More
Vincent visits the Australian Animal Health Laboratory in Geelong, Australia and speaks with Linfa about his work on bats and bat viruses.

The TWiVome discusses an miRNA based strategy to mitigate risk of gain of function studies, and identification of a second receptor required for Lassa virus entry.
The safety breach at a government lab that may have exposed 84 workers to live anthrax centered on a pivotal lapse in procedure: researchers working with the bacteria waited 24 hours to be sure they had killed the pathogens, half the time required by a new scientific protocol.
The lab designe... Read More
The burger patty that slides off the plate, the ice cream treat that plops on the picnic table, the hot dog that rolls off the grill – conventional wisdom has it that you have five seconds to pick it up before it is contaminated.
Fact or folklore?
“A dropped item is immediately contaminate... Read More
A University of Alberta researcher’s star is rising thanks to her idea to detect deadly pathogens such as E. coli using a paper device only slightly larger than a postage stamp.
Frédérique Deiss, a post-doctoral fellow in the Faculty of Science, is working on ways to help detect food- and wat... Read More
