NewsResearcher to study the arms race between bacteria and viruses
The two-way defence mechanisms of bacteria and phages, viruses of the bacteria, can offer a solution to antibiotic resistance problems.
-
NewsHypervirulent bacteria emerging in healthy people
New ’hypervirulent’ strains of the bacterium Klebsiella pneumoniae have emerged in healthy people in community settings, prompting researchers to investigate how the human immune system defends against infection.

NewsMould and algae blooms cited by patients as triggers for chemical intolerance
Toxic mould spawned by the moisture left behind by flood waters from Hurricane Idalia could lead to severe health problems for people who suffer from chemical intolerance, scientists have warned.

NewsAntibiotics promote the growth of antibiotic-resistant bacteria in the gut
Antibiotic-resistant bacteria get extra nutrients and thrive when the drugs kill ‘good’ bacteria in the gut, a new study reveals.
-
NewsNew species of marine bacteria isolated from a deep-sea cold seep
Scientists have isolated a new species of marine bacteria that multiplies by a unique budding mechanism and releases viruses to facilitate nitrogen metabolism.
-
NewsPatrolling honey bees expose spread of antimicrobial resistance
Bees could become biomonitors, checking their neighbourhoods to determine how far antimicrobial resistance (AMR) has spread, according to new research.
-
NewsTeam find promising bacterial suicide gene against citrus Huanglongbing and canker
Researchers have found that an endolysin encoded by the CaLas prophage has dual resistance to Huanglongbing and citrus canker.
-
NewsResistant E. coli rises despite drop in ciprofloxacin use
Community circulation of ciprofloxacin-resistant E. coli paradoxically increased after six-year reduction in antibiotic prescriptions.
-
NewsCargo system inhibits E.coli biofilms with a fraction of the antibiotic dose
Scientists have designed a bacteria-targeted cargo system that is capable of inhibiting a quinolone resistant Escherichia coli biofilm using much lower levels of antibiotic. The researchers, from Koç University School of Medicine in collaboration with College of Science, Department of Chemistry, encapsulated the antibiotic ciprofloxacin into superparamagnetic iron oxide nanoparticles ...

NewsSoil microplastics could usher superbugs into food supply
Micro- and nanoplastics in agricultural soil could contribute to antibiotic resistant bacteria with a ready route into our food supply, a new study warns.
-
NewsResearchers decode new antibiotic clovibactin
Researchers have discovered and deciphered the mode of action of a new antibiotic, clovibactin, which is derived from a soil bacterium.
-
NewsResearchers reveal how Salmonella relatives grow together in the gut
Scientists investigating the dynamics of bacterial coexistence in the gut discovered how a secondary group of bacteria can thrive when closely related resident bacteria are present.
-
NewsLifestyle changes while on antibiotics can help to fight AMR
Cooking food thoroughly and avoiding some types of vegetables and salad during a course of antibiotic treatment could potentially reduce antibiotic resistance, by preventing bacteria carrying resistance genes getting into the gut.
-
NewsOxygen charge can battle multidrug-resistant pathogens
Researchers have introduced a molecular singlet oxygen battery that can be ‘charged’ with reactive oxygen, which it then releases in deep tissue layers to target methicillin-resistant staphylococcus.
-
NewsSynthetic antibiotic could be effective against drug-resistant superbugs
Researchers have found a new antibiotic strategy to defeat gram-negative bacteria like Salmonella, Pseudomonas and E. coli, making use of a synthetic molecule that works fast and is durable in animal tests.
-
NewsAMR poses threat in all 35 countries in the Americas
569,000 deaths were linked to bacterial antimicrobial resistance in all 35 countries of the WHO Region of the Americas, according to a new study.
-
NewsResearchers reveal how the herpes virus HCMV deceives its host cells
Researchers have created a detailed map of the spatial interactions between viral and host cell proteins within HCMV particles, revealing that certain host cell proteins are recruited by viral proteins and play a role in viral replication.

NewsEgyptian cotton gene grants powerful resistance to resurging blight
An overlooked gene found in Egyptian cotton confers powerful resistance to bacterial blight, a plant disease that is threatening cotton production worldwide.
