NewsFirst evidence of fungal pathogen becoming more deadly when co-infected with tuberculosis
Co-infection of Mycobacterium tuberculosis, together with Cryptococcus neoformans, is a grave public health concern, increasing the risk of death significantly. Researchers have found that in the presence of Mycobacteria, the fungus changed its cell density, cell diversity, and capsule size.

News Huayunuo approval positions China at forefront of viral hepatitis innovation, says GlobalData
Huahui Health has recently secured conditional approval from China for Huayunuo (Libevitug Injection), marking it as the first domestically developed monoclonal antibody (mAb) drug for chronic hepatitis D virus (HDV) infection in adults with or without compensated cirrhosis.

NewsScrub typhus a threat in the home, study in South India finds
Most human scrub typhus infections could occur inside villages rather than during agricultural work, suggests new research conducted with the help of communities living in Tamil Nadu.

NewsElevated E. coli, staph still detected in Potomac river 4 weeks after sewage spill
Nearly a month after a wastewater pipe broke and spewed hundreds of millions of gallons of raw sewage into the Potomac River just north of Washington, D.C., the latest water testing results continue to show high levels of E. coli and S. aureus, including antibiotic-resistant MRSA.

NewsNew single-cell transcriptomic clock reveals intrinsic and systemic T cell aging in COVID-19 and HIV
Scientists developed a new single-cell transcriptomic clock called T immune cell transcriptomic clock (Tictock) to measure aging in specific immune cells. They found that in patients with acute Covid-19, the infection increased the biological age of naïve CD8 T cells.

NewsScientists home in on Acinetobacter baumannii’s resistance evolution
Scientists have found a way to understand how Acinetobacter baumannii is evolving - and how best to strategize a fight against it. They have produced a huge whole-genome look at the rise of this resistance, pointing the way to new strategies in staying ahead of the pathogen.

NewsHoly Grail: One vaccine may provide broad protection against many respiratory infections and allergens
In a new study in mice, researchers have developed a universal vaccine formula that protects against a wide range of respiratory viruses, bacteria and even allergens.

NewsNew findings on infection with the Epstein-Barr virus
Researchers have identified genetic and non-genetic factors that help the body fight the Epstein-Barr virus. Using a new technique, they were able to estimate the amount of EBV in the blood and find correlations in large health data sets – for example, an increased viral load in people with HIV infections, but also in smokers.

NewsMissed opportunity: Study shows low vaccination rates among expectant mothers in Norway against COVID-19 and influenza
A study of over 50,000 pregnant women in Norway during the 2023/24 influenza season found that only 29.9% were vaccinated against influenza and 12.1% against COVID-19 during pregnancy, remaining far below recommended targets.

NewsNewly discovered virus linked to colorectal cancer
Researchers have discovered a previously undescribed virus in a common gut bacterium, Bacteroides fragilis. The virus appears more frequently in patients with colorectal cancer.
-
NewsNew review points to faster, safer vaccine development
A new review examines viral mimic systems that reproduce key features of dangerous pathogens such as SARS-CoV-2, the virus that causes Covid-19, without the ability to replicate or cause disease. These systems allow researchers to study infection safely, quickly, and in a wider range of laboratories.

NewsResearchers discover how tuberculosis bacteria use a “stealth” mechanism to evade the immune system
New research reveals that mycobacteria release tiny packages called extracellular vesicles that fuse with the membranes of immune cells. These vesicles contain specialized lipids—fatty molecules—that make the cell membrane more rigid.

NewsPrenatal infection increases risk of heavy drinking later in life
Exposure to infection and other immune stress in the womb increases the likelihood of alcohol misuse in adulthood, a risk that may be reduced through prenatal antioxidant treatment, a new study shows.

NewsNovel vaccine protects against C. diff disease and recurrence
A novel vaccination approach cleared the harmful gut bacterium Clostridioides difficile in an animal model of infection. An experimental vaccine administered to the mucosal lining of the colon protected against illness, death, tissue damage and infection recurrence.

NewsExposing a hidden anchor for HIV replication
Scientists investigating HIV have revealed a previously unknown role for the viral protein integrase, which helps HIV insert itself into human DNA. A new study provides the first direct evidence that integrase plays a critical structural role earlier on in HIV’s life cycle — when the virus matures into an infectious force.

NewsAntimicrobial resistance in foodborne bacteria remains a public health concern in Europe
Antimicrobial resistance (AMR) in common foodborne bacteria such as Salmonella and Campylobacter continues to be a public health concern across Europe, according to a new joint report from EFSA and ECDC.

NewsComplexity key to preventing infection after heart surgery
Research indicates that uniform materials could be the culprit behind deadly infections that can occur when using synthetic materials for cardiovascular grafts.
-
NewsMacrophage immune cells need constant reminders to retain memories of prior infections
Researchers have discovered that immune cells known as macrophages remain poised to fight repeat infections due to the persistent presence of signaling molecules left behind during previous infections.

NewsPower grids to epidemics: study shows small patterns trigger systemic failures
Why do some systems collapse suddenly after what seems like a minor disturbance? In nature, a local disease outbreak can quickly escalate into an epidemic. New research suggests that in many cases, the key isn’t the entire system – but its smallest building blocks.

NewsBooster jabs reduce the risks of COVID-19 deaths, study finds
Booster vaccines reduced the risk of COVID‑19–related hospitalisation and death, according to a new study of over 3 million adults who had the autumn 2022 vaccine in England.
