NewsBirding enthusiasts can help songbirds avoid salmonella epidemics
Biologists are developing a tool to predict when deadly salmonella outbreaks are likely to happen in wild songbird populations so that people can protect their feathered friends by taking down bird feeders at the right time.

NewsProbiotic living microneedles designed by interbacterial competition for accelerated infected wound healing
Probiotic therapy offers a promising strategy for chronic infected wound management. Inspired by bacterial competitive interactions, researchers developed a multifunctional microneedle (MN) platform to overcome the limitations of weak competitiveness and poor penetration across biofilm barriers.

NewsA gentler way to model deadly lung infections in old age
Researchers report a refined mouse model that successfully mimics chronic Pseudomonas aeruginosa lung infection in old age. The study introduces an agar bead-based delivery strategy that allows bacteria to persist in the lungs of aged mice without causing rapid death.

NewsVaccine against foot-and-mouth disease could deliver $1.3 billion a year in global livestock benefits
A new foot-and-mouth disease vaccine is projected to deliver over $1.3 billion in annual benefits and transform global livestock resilience.

NewsSunlight-activated nanospray enables painless, antibiotic-free therapy for infected diabetic wounds
A research team has reported a multifunctional photodynamic nanospray for chronic infected wounds that harnesses natural sunlight to address persistent bacterial infections, impaired healing and severe pain simultaneously.

NewsGut bacteria protect mice with influenza A from bacterial pneumonia, study finds
Select gut bacteria protect mice against post-influenza virus secondary bacterial pneumonia, according to a study which sought to define whether intestinal bacteria influenced some individuals’ vulnerability to secondary bacterial infections following primary respiratory viral infection.
-
NewsCat disease challenges what scientists thought about coronaviruses
Researchers have uncovered new details about how a once-deadly coronavirus disease in cats spreads through the immune system. For years, the prevailing belief was that the virus behind feline infectious peritonitis infected just one type of immune cell.
-
NewsResearcher reveals secrets of bacteria that can swim upstream
Rather than washing pathogens away, strong fluid currents act as “guide rails” that align bacteria and accelerate their upstream migration. They discovered that this creates a “two-way invasion” where pioneer cells reach the source within minutes, seeding colonies that spread threefold faster than in still water.

NewsResearchers uncover the secret route of prostate infections
A research team has developed a “mini prostate” organoid model using adult stem cells. Using this model, the scientists could follow a bacterial prostatitis infection step by step under controlled conditions and identify exactly how the bacteria attack.

NewsUK: COVID-19 vaccine hesitancy decreased over time, though mistrust persists among certain groups
Most COVID-19 vaccine hesitancy is rooted in concerns that can be addressed and effectively reduced over time, according to a new study following more than 1.1 million people in England between January 2021 and March 2022 during the COVID-19 pandemic.

NewsClinical trial in Ethiopia targets the trachoma scourge
A new study documents the outcomes of an evaluation of fluorometholone as adjunctive medical therapy for trachomatous trichiasis surgery, part of an initiative to better prevent blindness and improve quality of life for those affected.

NewsNew study finds higher hantavirus risk in drier, underdeveloped areas
In a recent study of the contiguous USA, researchers found that the risk of disease from hantavirus is higher in drier, underdeveloped geographic areas with more socioeconomic vulnerability and increased numbers of unique rodent species.
-
NewsResearchers revive failing antibiotics with two-faced Janus nanoparticles
Researchers have restored the power of failing antibiotics by combining them with two-sided nanoparticles, ultra-small building blocks of materials less than 100 nanometers across. The nanoparticles showed a remarkable ability to compromise bacterial cell walls, leaving them vulnerable to attack.

NewsHow Mtb safeguards itself from foreign DNA
Researchers have discovered how a key protein in the tuberculosis bacterium helps protect it from the influence of foreign DNA inserted into its genome. Understanding how this protein – called Lsr2 – functions could help develop drugs that target it, thereby aiding in the fight against TB.
-
NewsNew test shows which antibiotics actually work
Drugs that act against bacteria are mainly assessed based on how well they inhibit bacterial growth under laboratory conditions. A critical factor is whether the active substances actually kill the pathogens in the body. Researchers have presented a new method for measuring how effectively antibiotics kill bacteria.
-
NewsTB harnesses part of immune defense system to cause infection
Scientists have made a discovery that helps explain why humans and animals are so susceptible to contracting tuberculosis – and it involves the bacteria harnessing part of the immune system meant to protect against infection. They team discovered that MTB survives within the cells of its host by targeting Dectin-1.

NewsA high-protein diet can defeat cholera infection
A new study has found that diets high in casein, the main protein in milk and cheese, as well as wheat gluten, could make a dramatic difference in the amount of cholera bacteria able to infect the gut.
-
NewsStudy: How can we stop the spread of flu?
Researchers wanted to find out how the flu spreads, so they put college students already sick with the flu into a hotel room with healthy middle-aged adult volunteers. The result? No one caught the flu.
-
NewsCholera vaccine completes phase 1 trial
A clinical trial shows promising results for PanChol, a single-dose oral vaccine aimed at the up to 4 million annual cholera cases worldwide.

NewsSub-lethal water disinfection may accelerate the spread of antibiotic resistance
A new study reveals that environmental stressors do not merely kill bacteria; they can also prime surviving cells to take up resistance genes more efficiently, raising concerns about how antibiotic-resistant bacteria may spread in aquatic environments.
