Bacteria Suppress Their Antibiotic-Resistant Cousins

Bacteria Suppress Their Antibiotic-Resistant Cousins

Researchers studying a dangerous type of bacteria have discovered that the bacteria have the ability to block both their own growth and the growth of their antibiotic-resistant mutants. The discovery might lead to better ways to fight a class of bacteria that have contributed to a growing public health crisis by becoming increasingly resistant to antibiotic treatments.

UT Austin Researchers Evaluate Methodology of Ebola Vaccine Trials

Medical aid workers in full protective gearThe waning number of Ebola cases is good news for West Africa, but for those developing a vaccine for the disease, it means time is running short.

HIV Not As Infectious Soon After Transmission As Thought

HIV Not As Infectious Soon After Transmission As Thought

People who recently have been infected with HIV may not be as highly infectious as previously believed, a finding that could improve global efforts to prevent HIV transmission and save lives.

Silent Ebola Infections Could Be Key to Controlling Outbreak

Silent Ebola Infections Could Be Key to Controlling Outbreak

In a letter published in the Lancet medical journal on October 14, Steve Bellan and Lauren Ancel Meyers, speculate that Ebola may be silently immunizing large numbers of people who never fal ill or infect others. If so, they might bolster front-line health care responses to the ongoing outbreak. Learn more in our press release.

Ebola virus

As Ebola continues to spread in West Africa, it may be silently immunizing large numbers of people who never fall ill or infect others, yet become protected from future infection. If such immunity is confirmed, it would have significant ramifications on projections of how widespread the disease will be and could help determine strategies that health workers use to contain the disease, according to a letter published Tuesday in the Lancet medical journal.

The Math of the Ebola Outbreak

The Math of the Ebola Outbreak

Dr. Lauren Ancel Meyers, a professor in the Department of Integrative Biology, was interviewed by the Huffington Post Science editor David Freeman. Meyers, a pioneer in the mathematical modeling of infectious diseases, discusses Ebola and how outbreaks of infectious diseases are governed by complex mathematics.

Scientists Develop Ebola Vaccine

Scientists Develop Ebola Vaccine
Since 2007, Maria Croyle and her colleageus have been developing a vaccine for the Ebola virus. The oral vaccine has been shown effective in rodents and primates and may soon be ready for human clinical trials. Croyle is a professor in the College of Pharmacy and member of the College of Natural Sciences' Center for Infectious Disease and Inst...

Trapping a Bacterium in a Laser Beam Aids Study of Biofilms

Trapping a Bacterium in a Laser Beam Aids Study of Biofilms

Scientists at The University of Texas at Austin have developed a technique to move and position a single bacterium using a highly focused laser. The precise control offered by this tool will allow researchers to better study how bacterial biofilms form.
