One health
Communicable diseases remain one of the major causes of mortality worldwide. There are disparities in the numbers of individuals affected by disease between low-and-middle-income countries and those in developed nations. Microbes will play in important role in drug discovery: producing anticancer drugs and antimicrobials. Applying One Health principles, to understand the interaction of pathogens and the human host, development of diagnostics, treatments, and disease prevention, applied microbiologists can shape global health and wellbeing outcomes.

NewsNasal spray could transform treatment of deadly cerebral malaria
Master’s student Taznita Kista is exploring whether a nano-enabled nasal spray could change how cerebral malaria is treated. Her work focuses on a nose-to-brain drug delivery system using niosomes.
NewsFlu vaccine no longer required for U.S. military
The U.S. military is ending its long-standing requirement that service members receive the annual flu shot, a decision announced by Defense Secretary Pete Hegseth.

IBS treatment response predicted by gut microbiome in new study
Researchers investigating irritable bowel syndrome with diarrhea observed distinct characteristics of patients’ gut microbiomes that predicted whether they responded to the low FODMAP diet or rifaximin — or did not respond to treatment.
NewsNew research reveals mechanisms behind coffee’s positive effects on the gut-brain axis
First of its kind research shows the potential role of coffee as a further intervention to promote positive gut health and its effects on the gut-brain axis. Coffee was found to positively affect perceived mood and stress levels in individuals taking part in this study.
NewsE. coli and ‘good’ bacteria balanced by breastmilk in baby gut microbiomes
Sugars contained exclusively in breast milk are helping to feed an important balance of bacteria in babies’ developing gut microbiomes, according to a study that describes how babies who are breastfed maintain a mutually beneficial co-existence of E. coli and Bifidobacterium.
NewsResearchers disable antimicrobial resistance in cystic fibrosis-associated bacteria
A newly discovered mechanism renders antibiotic-resistant bacteria vulnerable by disabling both their individual resistance and a process known as cross-protection, the ability of resistant bacteria to shield nearby, otherwise sensitive strains.
NewsMetagenomic software advance boosts research into microbial diversity
Researchers studying the diversity of microbes in environmental samples now have access to a new tool that opens the door to cheaper, more accessible analysis of their samples.
NewsStudy shows links between Alzheimer’s and gut health can lead to prevention
Researchers analysed more than 120 everyday factors, including diet, medical history, gut bacteria, and lifestyle, to identify which of them are most strongly associated with Alzheimer’s risk. People who had their appendix removed showed substantially elevated Alzheimer’s risk.
NewsIs asphalt bad for our health? And can algae help?
Scientists studying how asphalt emissions impact respiratory health are also working on less toxic, lower-emitting asphalt formulations. One project involves growing a strain of algae that could reduce VOC emissions using wastewater from a treatment plant.
NewsResearchers combine polarized light and a magnetic field to spot malaria under the microscope
Researchers have developed a new microscopy method that uses a magnetic field and polarized light to provide quantitative measurements that could enable faster and more objective detection of malaria in blood.
NewsRising measles cases highlight gaps in vaccination coverage and public health system vulnerabilities
The Global Virus Network (GVN) is closely monitoring a significant resurgence of measles in the United States and globally, reflecting a growing vulnerability in public health systems.
NewsCDI breakthroughs lead to new drug development deal for deadly NTM bacteria
Scientists have developed new compounds against non-tuberculous mycobacteria which are now the subject of a new collaboration and license agreement with the Switzerland-based and publicly listed BioVersys AG.
NewsEarly immune responses linked to protective HIV antibodies
In a new study of broadly neutralizing antibodies and their potential for an HIV vaccine, researchers analyzed fragments of cell-free RNA and DNA circulating in the blood. This makes it possible to track immune responses, viral genetic variation, and other microbes from the same blood sample.
NewsNew research reveals cell proteins that drive severe viral infections
Researchers have identified two human cell proteins, NUP98 and NUP153, that play a crucial role in how viruses such as tick-borne encephalitis virus (TBEV), West Nile virus, and dengue virus replicate in the body.
NewsMillions suffering needlessly with curable hepatitis C, new analysis reveals
Millions of Americans are still battling potentially deadly hepatitis C even though they could be cured with antiviral drugs they are not receiving, a new analysis reveals.
NewsHas life-saving HIV therapy contributed to increased rates of a sexually transmitted disease?
A study has uncovered an unintended consequence of a major medical breakthrough: while the availability of HIV treatments in the late 1990s dramatically improved survival, they also contributed to a resurgence in syphilis, a sexually transmitted infection.

NewsScientists map how HIV hijacks human cells—and how cells can fight back
Scientists have opened a new door to understanding HIV by creating the first comprehensive genetic roadmap of how the virus interacts with real human cells. They identified a multitude of hidden players in HIV infection, human proteins that either help the virus thrive or work to stop it.

NewsOral-gut axis points to salivary biomarkers for early gastric cancer detection
A recent study has identified distinct microbial “signatures” within the oral cavity and gut that serve as robust biomarkers for the early detection of gastric cancer (GC). Research shows how specific lactic acid-producing bacteria (LAB) migrate from the mouth to colonize the gastrointestinal tract.
