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.

NewsBeyond gene scissors: New CRISPR mechanism discovered
Two studies describe how researchers found a novel CRISPR mechanism, Cas12a2, in a family of nucleases that exclusively cleave DNA. In contrast, Cas12a2 was able to broadly cleave both RNA and DNA.

NewsCommon brain parasite can infect your immune cells. Here’s why that’s probably OK
Researchers have determined how our immune systems fight back against the parasite Toxoplasma gondii when it makes it inside the CD8+ T cells meant to destroy it.

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.

NewsFatal infection risk in newborns may increase when this bacteria and fungus mix
A new study reveals that when Streptococcus agalactiae (GBS) interacts with Candida albicans, GBS is more likely to spread disease and become harder to treat in newborns. Infection by both microbes reduces the effectiveness of existing GBS treatments.
-
NewsDiscovery could lead to new treatments for drug-resistant fungal infections
Researchers have identified a molecule that may help turn the tide on fungal infections — butyrolactol A, a chemical compound that targets a deadly, disease-causing fungi called Cryptococcus neoformans.
-
NewsInternational experts connect infections and aging through cellular senescence
Researchers propose the concept of infection-driven senescence (IDS) to describe the phenomenon in which microbial agents, beyond viruses, can trigger cellular senescence in host cells.
-
NewsNew clinical standards strengthen antimicrobial stewardship in tuberculosis care
An international panel of experts from 32 countries has presented specific antimicrobial stewardship standards for TB care for the first time.

NewsNew database to target chronic UTIs – a long-overlooked condition that may begin in childhood
A new database targeting chronic urinary tract infections (UTIs) – a long-overlooked condition that may begin in childhood – is set to help researchers uncover why millions of women and girls worldwide suffer from infections that defy treatment and stump microbiologists.

NewsHow the parasite that ‘gave up sex’ found more hosts – and why its victory won’t last
A study has revealed a genetic shortcut that may help Giardia duodenalis and many other parasites jump to new hosts at the cost of long-term survival. The findings may also help explain how parasites evolve drug resistance.
