In the 1960’s, the microbicide triclosan, was introduced in the United States, and soon after, human weight started to increase dramatically. For some time, researchers have wondered whether triclosan could have played a role in disrupting endocrine dysfunction and contributing to the obesity ep... Read More
The TWiXers discuss a study on vertical transmission of Zika virus by Aedes mosquitoes, and uncovering Earth's virome by mining existing metagenomic sequence data.

Washington, DC – August 17, 2016 – The multidrug-resistant yeast Candida auris, which has caused fatal infections in some hospitalized patients, has at least two different growth patterns and some of its strains are as capable of causing disease as the most invasive type of yeast called Candida ...

Leonilde M. Moreira, PhD, has been studying the Burkholderia complex for 15 years. The bacteria, known for causing pneumonia or septicemia in some individuals, can survive for prolonged periods in moist environments. During the last 10 years, it has become one of the more predominant bacteria se... Read More
From the EIDA2Z conference at Boston University, Vincent, Alan and Paul meet up with Ralph Baric, Felix Drexler, Marion Koopmans, and Stacey Schultz-Cherry to talk about discovering, understanding, protecting, and collaborating on emerging infectious diseases.

Polio returns to Nigeria, Zika virus spreads in Miami, and virus infection of plants attracts bumblebees for pollination, from the virus gentlepeople at TWiV.
Although the Gram-negative bacterium Vibrio cholerae (right) is normally associated with human pathogenic disease, most V. cholerae cells spend their lives in an aquatic environment, and only a few of the many serotypes are able to cause disease. When strains acquire the right genetic makeup – s... Read More
Host: Jeff Fox with special guest, Emma Wilson.
Emma H. Wilson of the University of California, Riverside, talks with Jeff Fox about efforts, with her collaborators to determine more precisely how Toxoplasma gondii parasites disrupt the mammalian brain—in this case, the brains of mice... Read More
Jennifer joins Vincent, Elio, and Michael to talk about the work of her laboratory on how a respiratory virus enhances bacterial growth by dysregulating nutritional immunity.

Washington, DC - August 18, 2016 - A team of researchers from Utah State University, Logan, has characterized the consensus genome sequences of three historically important Zika virus strains. This work is an important step towards developing antiviral therapeutic and preventive strategies again... Read More
While carbapenems aren’t allowed to be given to feedlot animals, other beta-lactam antibiotics are. This is a large class of drugs that includes extended-spectrum cephalosporin drugs. There is no direct line between the use of these extended-spectrum cephalosporins and selection for carbapenem r... Read More

Dear Vincent, Elio, Michael, and Michelle,
I've just recently finished TWiM number 133 and wanted to comment about the use of the term "secondary metabolite" throughout the episode and often in the primary literature. Michael pointed out that a se... Read More
Zika virus RNA has been detected in New World monkeys from the Northeast region of Brazil. This finding suggests that primates may serve as a reservoir host for the virus, as occurs in Africa. Read More
