The bacterium Salmonella Typhi causes typhoid fever in humans, but leaves other mammals unaffected. Researchers at University of California, San Diego and Yale University Schools of Medicine now offer one explanation — CMAH, an enzyme that humans lack. Without this enzyme, a toxin deployed by the bacteria is much better able to bind and enter human cells, making us sick.
Joy and goodwill aren’t the only things we start spreading to friends, family, colleagues -- even strangers -- this time of year. Late fall and early winter also signal the start of annual spread of the influenza virus.
As Ebola raises difficult questions, ethics trailblazers answer with a road map for 21st-century nursing
Beginning today, anyone can download a safe and free app that will put their computer or Android-based mobile device to work to form a virtual supercomputer to help The Scripps Research Institute screen millions of chemical compounds to identify new drug leads for treating Ebola.
Researchers reveal that a protein responsible for regulating the body's sleep cycle, or circadian rhythm, also protects the body from developing sporadic forms of cancers.
To stop the spread of HIV in Africa, researchers at UCLA, using a complex mathematical model, have developed a strategy that focuses on targeting “hot zones,” areas where the risk of HIV infection is much higher than the national average.
In support of Strategies for Fighting Ebola: A Columbia University Summit to Help End the Epidemic, held this week at the Columbia Club in New York City, MavenMagnet, a multinational big data-based research company, conducted a study to understand the current U.S. public perceptions of Ebola.
Redbay ambrosia beetles can bring the laurel wilt disease to avocado trees, ravaging the trees and crop. But UF/IFAS researchers may have found a biological control for the beetles.
Diagnosing HIV and other infectious diseases presents unique challenges in remote locations that lack electric power, refrigeration, and appropriately trained health care staff. To address these issues, researchers funded by the National Institutes of Health (NIH) have developed a low-cost, electricity-free device capable of detecting the DNA of infectious pathogens, including HIV-1.
Of about 450 different species of mosquitoes in the Anopheles genus, only about 60 can transmit the Plasmodium malaria parasite that is harmful to people. The team chose 16 mosquito species that are currently found in Africa, Asia, Europe, and Latin America, but evolved from the same ancestor approximately 100 million years ago.
The bacterium Helicobacter pylori is strongly associated with gastric ulcers and cancer. To combat the infection, researchers at University of California, San Diego School of Medicine and Jacobs School of Engineering developed LipoLLA, a therapeutic nanoparticle that contains linolenic acid, a component in vegetable oils. In mice, LipoLLA was safe and more effective against H. pylori infection than standard antibiotic treatments.
A Creighton physics faculty member and alum is part of a research group that discovered a new way the body fights bacterial infection.
Johns Hopkins biomedical engineers have developed a free, browser-based online tool that could speed up the creation of new drugs to treat or prevent Ebola virus infections.
Just-published findings in the journal AIDS raise concern about potential long-term harmful impact of “antiretroviral therapy” on in-utero infants whose mothers are HIV-positive, but who are not infected with HIV themselves.
In a comprehensive new study published today in the journal Cell Host and Microbe, the University of Wisconsin-Madison’s Yoshihiro Kawaoka and a team of researchers have revealed methods for thwarting influenza viruses by shutting down the cellular machinery they need, like cutting the fuel line on a bank robber’s getaway car.
The Baltimore study is the second Ebola vaccine trial being led by the University of Maryland School of Medicine CVD, the first currently taking place in Mali, West Africa. The Mali trial is being performed by CVD-Mali in partnership with the Ministry of Health of Mali.
A nasal vaccine in development by researchers at The University of Texas at Austin has been shown to provide long-term protection for non-human primates against the deadly Ebola virus.
Microbiologists at NYU Langone Medical Center say they have what may be the first strong evidence that the natural presence of viruses in the gut — or what they call the ‘virome’ — plays a health-maintenance and infection-fighting role similar to that of the intestinal bacteria that dwell there and make up the “microbiome.”
Another family of viruses, deadly in some cases, may have already jumped from fruit bats into humans in Africa, according to a study published today in the journal Nature Communications.
A new study from Penn Medicine researchers in the Center for Clinical Epidemiology and Biostatistics demonstrated that bed bugs, like the triatomines, can transmit Trypanosoma cruzi, the parasite that causes Chagas disease, one of the most prevalent and deadly diseases in the Americas.
