NewsDirect rescue of segmented negative-sense RNA viruses from complementary DNA in monkey kidney Vero cells
This technology enables the direct rescue of segmented negative-sense RNA viruses from complementary DNA in monkey kidney Vero cells, facilitating safer and more efficient live-attenuated vaccine production.

NewsPartners in crime produce extreme antibiotic resistance
A study shows how environmental bacteria enter the lungs during an infection and transfer antibiotic resistance genes to disease-causing bacteria.
-
NewsNovel plasmid confers phosphorylation-driven streptomycin resistance in plant pathogen
The genetic basis underlying the unusually high-level streptomycin resistance observed in the field-derived strain TX-0702 of Clavibacter michiganensis has remined unknown until a new study identified a previously uncharacterized plasmid.

NewsSunlight and PVC pipes create a hidden driver of antibiotic resistance
New research shows that chemicals leaching from everyday PVC—especially after exposure to sunlight—can dramatically speed up the spread of resistance genes between bacteria. The effect was strongest at low to moderate concentrations, where the leachate triggered bacterial stress responses without killing the microbes.
-
NewsGene-sharing myth challenged as bacteria shown to police DNA exchange
A new study reveals that bacteria can actively limit the spread of antibiotic resistance genes, using a newly characterized mechanism that blocks DNA transfer between cells. It focuses on how bacteria exchange genetic material through tiny intercellular bridges known as nanotubes.
-
NewsCinnamic acid blocks plasmid conjugation to slow antibiotic resistance spread
A new study reveals that cinnamic acid, a widely used food additive found in cinnamon, can effectively inhibit plasmid‑mediated conjugation, a major route for the global spread of antibiotic resistance genes (ARGs).

NewsMapping the hidden gene highways of wastewater biofilms
A new study uncovers the hidden microbial connections within wastewater biofilms by combining Hi-C sequencing with multi-omics to directly map which phages and plasmids are associated with which microbial hosts.

NewsBacterial hitchhikers can give their hosts super strength
Molecular hitchhikers living within bacteria can make their hosts extra resistant to medical treatment by corralling them into tightly packed groups. The study introduces a previously unknown avenue through which bacterial infections can become more difficult to treat.

NewsNext generation genetics technology developed to counter the rise of antibiotic resistance
The new Pro-Active Genetics (Pro-AG) tool called pPro-MobV is a second-generation technology that uses an approach similar to gene drives to disable drug resistance in populations of bacteria.

NewsResearchers develop novel tracking method to reveal spread of antibiotic resistance across Hong Kong’s environment
Researchers have harnessed citywide genetic data and developed a novel genome-resolved tracking method to uncover precisely how antibiotic-resistant bacteria and their resistance genes move across Hong Kong’s environment.
-
NewsResearchers subvert plasmids to combat antibiotic resistance
Scientists have devised a way to track the evolution and spread of antibiotic resistance in individual bacteria by measuring competition among plasmids. Plasmids evolve independently but also help drive bacterial evolution, including the development of resistance to antimicrobial compounds. They are the primary way that resistance can jump from one type of bacteria to another.

NewsGenetic culprits IDed in capture of 100 years of antibiotic resistance evolution
The genetic culprits responsible for the spread of multidrug resistance (MDR) in bacteria have been identified by new research mapping 100 years of bacterial evolution.
-
NewsStudy identifies gene clusters in rhizobia linked to robust legume growth
A new study identified clusters of rhizobial genes that appear to move rapidly through bacterial populations and drive greater plant biomass in host plants. Understanding the interplay of host and bacterial genomes will help to optimize plant growth by improving the rhizosphere.

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.
-
NewsPrecision medicine could be possible in the fight against antibiotic resistance
The first-of-its-kind in-depth bacterial evolutionary map could pave the way for the development of precision treatments for certain antibiotic-resistant infections, such as urinary tract infections.

NewsDeadly antibiotic-resistant ‘superbug’ bacteria spreading in Malaysian hospital
A virulent strain of antibiotic-resistant ‘superbug’ that causes severe disease has been found circulating in a Malaysian hospital - posing significant challenges to global public health, a new study reveals.
-
NewsRice research team creates universal RNA barcoding system for tracking gene transfer in bacteria
An interdisciplinary group of researchers at Rice University has developed an innovative RNA “barcoding” method to track gene transfer in microbial communities, providing new insights into how genes move across species.
-
NewsCuriosity-driven experiment helps unravel antibiotic-resistance mystery
An international collaboration has achieved an important breakthrough in understanding the genetic mechanisms that allow bacteria to build resistance to drugs.
-
NewsResearchers have uncovered how foreign DNA can evade bacterial defense systems and neutralize them
A new study reveals how bacterial defense mechanisms can be neutralized, enabling the efficient transfer of genetic material between bacteria.

NewsSymbiotic bacterium affects reproduction of biological control insect
Researchers have revealed that the symbiotic bacterium Rickettsia induces strong cytoplasmic incompatibility (CI) in the predatory mirid bug, Nesidiocoris tenuis, which preys on agricultural pests such as whiteflies and thrips.
