NewsResearch team discovers molecular mechanism for a bacterial infection
Researchers have discovered the mechanism by which the bacterial pathogen Shigella flexneri, the causative agent of dysentery, manipulates molecular activity to assure its survival against its host’s natural defenses.
-
NewsResearchers awarded $3 million grant to explore gut health
A $3 million grant has been awarded to investigate the energy generating processes of gut Bacteroides and how they impact our well-being.
-
NewsScientists ID combination of bacterial strains that could treat antibiotic-resistant gut infections
Researchers have isolated 18 bacterial strains from stool from healthy people that could potentially be an effective treatment for antibiotic-resistant bacterial infections in patients with chronic inflammatory intestinal conditions.
-
NewsScientists evolve microbial cultures that can sense pH changes
Scientists have successfully evolved microbial cultures that possess the ability to sense pH changes, enabling rapid responses to environmental fluctuations.
-
NewsImmune response to dengue can predict risk of severe reinfections
Researchers have found that natural killer T (NKT) cells influence whether the immune response generates protective antibodies that neutralise dengue virus or harmful ones that could exacerbate the disease in future infections.
-
NewsResearchers home in on vaccine target in an ancient scourge
Researchers and doctors have collected one of the most extensive genomic surveys of the syphilis bacterium to date and correlated the genetic data with clinical information about the patients who provided the samples.
-
NewsTwo-dose schedule could make HIV vaccines more effective
Researchers have found that the first dose primes the immune system, helping it to generate a strong response to the second dose, a week later.
