NewsNewly discovered ability of comammox bacteria could help reduce nitrous oxide emissions in agriculture
An international research team has discovered that comammox bacteria can grow using guanidine, a nitrogen-rich organic compound, as their sole energy and nitrogen source, opening new avenues for targeted cultivation of these enigmatic microbes.

NewsResistance found in parasite infecting cutaneous leishmaniasis patient
Researchers who analyzed samples from a 46-year-old patient in Brazil found an amphotericin B-resistant strain of the parasite Leishmania amazonensis circulating for the first time in the country.

NewsCould manure and compost act like probiotics, reducing antibiotic resistance in urban soils?
Urban soils often contain chemical contaminants or trace amounts of antibiotics, along with higher levels of antibiotic-resistant bacteria. New research suggests that boosting urban soil health with compost and treated manure may reduce the amount of ’bad’ bacteria.

NewsEfflux pumps conferring antibiotic resistance found in archaea for the first time
Scientists have discovered antibiotic resistance mechanisms called efflux pumps in archaea for the first time.

NewsFirst-of-its-kind vaccine expands malaria protection for pregnant women
For the first time, immunization with a malaria vaccine has been shown to protect mothers from malaria during pregnancy and to protect for two transmission seasons without booster doses of vaccine.

NewsScientists uncover how microbial enzymes lap up carbon dioxide
The remarkable affinity of the microbial enzyme iron nitrogenase for the greenhouse gas CO2 makes it useful for future biotechnology, a new study suggests.

NewsHydrometeorology and location affect hospitalizations for waterborne infectious diseases in the US
An analysis of 12 years of data collected from over 500 hospitals in 25 different states shows that weather, geographic location, and urban or rural location all appear to influence hospitalizations for waterborne infectious diseases.

NewsC-section antibiotics impact the infant microbiome far less than infant diet
A study has confirmed that although prophylactic antibiotics given ahead of a Caesarian section can cause subtle changes to the infant microbiome, they are much less significant than the impact of how the babies are fed.

NewsDairy farmer study reveals need for greater One Health understanding in AMR management
A new study has found a need for greater engagement and collaboration between veterinarians, farmers and regulators to improve understanding and management of antimicrobial resistance and One Health amongst Aotearoa New Zealand farmers.

NewsEarly life exposure to common chemical permanently disrupts gut microbiome
A study in mice finds that by significantly disrupting the gut microbiome, early life exposure to persistent organic pollutants influenced the development of metabolic disorder in adult mice.

NewsStudy finds shingles increased risk of subsequent cognitive decline
A new study has found that an episode of shingles is associated with about a 20 per cent higher long-term risk of subjective cognitive decline, providing support for getting the shingles vaccine to decrease risk of developing shingles.

NewsNew evidence for a connection between antibiotic use and autoimmune diseases
A new connection has been revealed between depletion of gut bacteria caused by antibiotics and development of autoimmune diseases. Clearance of dead cells involves not only local signals from within a tissue but also distant signals from other parts of the body.

NewsResearchers find promising new weapon against certain types of antibiotic-resistant bacteria
Researchers have discovered a new combination of substances that appears to combat a range of bacteria that causes conditions such as stomach ulcers and urinary tract infections, and that are increasingly developing antibiotic resistance.

NewsNew method for protection from plant pathogens could help support global food security.
By modifying a plant intracellular immune receptor (NLR), researchers have developed a potential new strategy for resistance to rice blast disease, one of the most important diseases threatening global food security. The collaborative team from the UK and Japan have recently published their research in PNAS. This could have implications ...

News City birds found to be carriers of antimicrobial resistant bacteria
Researchers have found that wild birds such as ducks and crows living close to humans, for example in cities, are likely to carry bacteria with antimicrobial resistance (AMR).

NewsScientists reveal how bacteria in lakes fight climate change
Methane is a potent greenhouse gas frequently produced in the sea and in fresh water. Lakes in particular release large quantities of this climate-killer. Fortunately, however, there are microorganisms that counteract this: They are able to utilize methane to grow and generate energy, thus preventing it from being released into ...

NewsLargest study of its kind finds common lab tests aren’t reliable for diagnosing Long COVID
A new study found that most routine laboratory tests are not reliable for diagnosing Long Covid, also known as Post-Acute Sequelae of SARS-CoV-2 infection (PASC).

NewsTicks’ secret allies: Bacteria’s hidden hand in tick survival
A new study of the relationship between the brown dog tick, Rhipicephalus sanguineus, and its Coxiella-like symbiotic bacteria reveals the bacteria help the ticks by providing essential B vitamins and possibly other nutrients like L-proline.

NewsStudy reveals oleoyl-ACP-hydrolase underpins lethal respiratory viral disease
Respiratory infections can be severe, even deadly, in some individuals, but not in others. Scientists have gained new understanding of why this is the case by uncovering an early molecular driver that underpins fatal disease.
