A new tool -- a type of ultraviolet light called UVC -- could aid hospitals in the ongoing battle to keep drug-resistant bacteria from lingering in patient rooms and causing new infections.
Some hospitals have already begun using UVC machines in addition to standard chemical disinfection to k... Read More
Drugs used to treat HIV could affect how the body responds to syphilis, inadvertently contributing to a current outbreak, a new study suggests.
In this study, researchers investigating the outbreak hypothesize that medications used in highly active antiretroviral therapy (HAART), the gold sta... Read More
A panel of small molecules that inhibit Zika virus infection, including one that stands out as a potent inhibitor of Zika viral entry into relevant human cell types, was discovered by researchers from the Perelman School of Medicine at the University of Pennsylvania. Publishing in Cell Reports t... Read More
New research conducted at the University of Miami in Coral Gables, Florida and the National Cancer Institute, in Bethesda, Maryland demonstrate that a subset of bacteriophages, dubbed “superspreaders,” potentially play a major role in transmitting antimicrobial resistance. The research, describe... Read More
Trudy joins the the TWiVlords to discuss new tests for detecting prions in the blood, and evidence showing that foamy retroviruses originated in the seas with their jawed vertebrate hosts at least 450 million years ago.
Hosts: Read More
Many mBiosphere readers will know that the influenza A virus infects multiple species, and this ability to infect birds, humans, and other mammals such as pigs is one of the ways virions can exchange genetic information, leading to new viruses able to cause major outbreaks. However, few mBiosphe... Read More
The world has a problem: an exploding human population, which will require crop yields to double by 2050 without increasing crop acreage. Solving this problem will necessitate help from some of the smallest members of Earth’s population using a concept that has both George Washington Carver and ... Read More
With Chagas disease becoming more prevalent in the United States, a diagnostic to quickly and easily detect infection is needed. Today, IDRI (Infectious Disease Research Institute) announces that a fusion antigen it developed and patented is being used as part of a Chagas disease diagnostic test... Read More
Although cases of Zika virus infection appear to be decreasing, the mosquito-borne virus likely will become endemic in the Americas and continue to cause outbreaks and sporadic cases. Given the serious complications of Zika virus infection, particularly in cases of congenital infection, research... Read More
If it sometimes seems like the idea of antibiotic resistance, though unsettling, is more theoretical than real, please read on.
Public health officials from Nevada are reporting on a case of a woman who died in Reno in September from an incurable infection. Testing showed the superbug that ha... Read More
A team of researchers from the Massachusetts General Hospital (MGH) and the Ragon Institute of MGH, MIT and Harvard has found that the most common bacterial community in the genital tract of healthy South African women is associated with a more than four-fold increase in the risk of acquiring HI...

Bacterial cells have an added layer of protection, called the cell wall, that animal cells don’t. Assembling this tough armor entails multiple steps, some of which are targeted by antibiotics like penicillin and vancomycin.
Yet one step in the process has remained a mystery because the molecu... Read More
Following the recent Zika outbreak in Miami-Dade County, a multidisciplinary team of physicians with the University of Miami Health System and Miller School of Medicine published a case study January 11 in the New England Journal of Medicine, describing in detail the nation’s first locally trans...

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
