NewsUrban rats spread deadly bacteria as they migrate, study finds
Urban rats spread deadly bacteria as they migrate within cities that can be the source of a potentially life-threatening disease in humans, according to a six-year study that also discovered a novel technique for testing rat kidneys.

NewsScientists introduce new engineered drug candidate for Mycobacterium abscessus to save lives
Scientists have introduced a promising drug candidate engineered to target a deadly and emerging infection. They took a hyper-detailed look into the problem of Mycobacterium abscessus, and chemically re-engineered a widely-used rifamycin antibiotic.

NewsResearch advances on ‘displacing’ antibiotic resistance gene from bacteria
Scientists have identified essential genetic code for a method called plasmid curing, which aims to ‘displace’ antibiotic resistance genes from bacteria.
-
NewsUltimate self-sacrifice: Bacteria activate unusual defense to evade viral attack
Scientists discover that the restriction modification system in some bacteria can kill the cell as a last resort if viruses try to thwart it. They trigger their own death using components of the very same systems that the phages were trying to inhibit.

NewsNew molecular label could lead to simpler, faster tuberculosis tests
Chemists have demonstrated that they can label a glycan called ManLAM using an organic molecule that reacts with specific sulfur-containing sugars. These sugars are found in only three bacterial species, including the microbe that causes TB.

NewsScientists uncover the link between ‘good’ gut bacteria and rheumatoid arthritis
After spending years tracing the origin and migration pattern of an unusual type of immune cell in mice, researchers have shown how activity of “good” microbes in the gut is linked to rheumatoid arthritis and, potentially, other autoimmune diseases.

News$2.7 million NIH grant to fund first comprehensive syphilis test
With a four-year, $2.7 million grant from NIAID, researchers aim to develop a one-step confirmatory laboratory test that can definitively diagnose active syphilis infection within 10 minutes.
-
NewsA digestive ‘treasure chest’ shows promise for targeted drug treatment in the gut
A new approach to drug design can deliver medicine directly to the gut in mice at significantly lower doses than current inflammatory bowel disease treatments.

NewsDesigner microbe shows promise for reducing mercury absorption from seafood
Scientists who inserted DNA-encoding methylmercury detoxification enzymes into the genome of an abundant human gut bacterium found it detoxified methylmercury in the gut of mice and dramatically reduced the amount that reached other tissues.

NewsStudy of facial bacteria could lead to probiotics that promote healthy skin
Researchers have revealed the dynamics of interactions between two dominant skin bacterial species in more detail than previously possible, shedding light on when and how new bacterial strains emerge on the skin of the face.
-
NewsBacteria deployed as living test tubes to study human gene mutations
Bioengineers have developed a new simple approach to rapidly check on human gene changes and also screen chemicals as potential drugs by turning everyday bacteria into living test tubes.
-
NewsBacteria use ancient war trick to outsmart viruses – and it could help us fight superbugs
Scientists have discovered a new type of immune defense in E. coli bacteria that turns viral infection machinery against the virus itself. They’ve named it Kongming after the Chinese military strategist who famously used enemy weapons to defeat his foes.

NewsNovel compound inhibits the growth of tumor-associated Fusobacteria
Researchers seeking ways to eliminate fusobacteria in carcinomas have made an unexpected discovery: their control compound, FUS79, which did not target a specific transcript, exhibited strong activity against five fusobacterial strains without affecting other tested bacterial species.
-
NewsResearchers reveal how human genetics and intratumoral microbiota affect colorectal cancer
A study shows that the single-nucleotide polymorphism (SNP) rs2355016—a tiny DNA change that some people carry—affects how intratumoral microbiota adhere to tumor cells, promoting colorectal cancer progression.
-
NewsBroader antibiotic use could change the course of cholera outbreaks, research suggests
Disease modeling research suggests that, for some cholera outbreaks, prescribing antibiotics more aggressively could slow or stop the spread of the disease and even reduce the likelihood of antibiotic resistance.
-
NewsFungi dwelling on human skin may provide new antibiotics
Researchers have uncovered a molecule produced by yeast living on human skin that showed potent antimicrobial properties against a pathogen responsible for a half-million hospitalizations annually in the United States.
-
NewsA hidden control center: How bacteria regulate their attack strategies
Researchers have discovered that a key bacterial protein, CsrA, gathers in a droplet-like structure inside cells to control when and how bacteria activate their disease-causing genes.
-
NewsBacteria’s mysterious viruses can fan flames of antibiotic damage, according to new model
Researchers built a model that allows them to diminish phage communities from a mouse gut microbiome — and then bring them back — without affecting the bacteria. A test run found evidence that phages may increase gut bacteria’s sensitivity to antibiotics.

NewsAntibiotic resistance: Towards drugs to disarm bacteria
Researchers have identified the mutation frequency decline (Mfd) protein, a virulence factor produced by all bacteria and essential for them to resist the host immune system. This protein has the additional function of promoting spontaneous and random mutations.

NewsTick researchers identify new strain of rickettsia bacteria that causes spotted fever infections in humans
In a residential backyard in Maine, researchers stumbled upon a surprise finding: rabbit ticks harboring a new type of bacteria related to a group of pathogens that can cause sometimes life-threatening spotted fever rickettsioses (SFR) infections in humans.
