NewsResearch into zoonotic disease risks requires a One Health approach
A new evidence brief, based on a study by the Juno Evidence Alliance conducted in collaboration with CABI’s One Health Hub, has highlighted that a One Health approach is needed in research into zoonotic disease risks around the world.

NewsMalaria parasites move on right-handed helices
After penetrating the skin, the malaria parasite moves with helical trajectories, almost always turning toward the right. Researchers demonstrated that the pathogen uses these right-handed helices to control its motion as it transitions from one tissue compartment to another.

NewsEmerging human and canine leptospirosis in New South Wales shows separate transmission pathways
A geospatial study of leptospirosis outbreaks in New South Wales suggests that humans and dogs may have largely independent transmission pathways.

News‘FluWarning’ system raises early alerts for virus spillovers
How can we monitor the cross-species transmission of avian flu? The answer is FluWarning, a digital system that reports abnormal changes in flu viruses. It analyses their genetic code, looking for subtle but significant changes that could indicate cross-species transmission.

NewsNew vaccine against a deadly virus acts fast and protects for over a year
A research team has developed a vaccine made from a non-infectious version of the Crimean-Congo hemorrhagic fever virus that protects quickly and provides long-lasting immunity.

NewsGlobal Virus Network awards pandemic preparedness grants to advance global surveillance and early detection of viral threats
The Global Virus Network (GVN) is awarding pandemic preparedness research grants, totaling $160,000, to scientists across four continents, supporting innovative, investigator-led projects designed to enhance viral surveillance, early detection, and scientific preparedness.

NewsStudy unveils structure, identification and characterization of the RibD-enolase complex in Francisella
A study aiming to identify anti-tularemia drug targets determined the atomic structure and identified its components of the native RibD-enolase protein complex in Francisella novicida.

NewsImpact of pasteurization on dairy calves’ gut microbiota: A study of milk feeding and early microbial colonization
A new study highlights the impact of pasteurization on microbial diversity in dairy calves, underlining the importance of balancing pathogen safety and microbial health. It suggests that while pasteurization prevents pathogen transmission, it also reduces beneficial microbial transfer.

News$3.7 million awarded for research into sand flies, vectors of parasitic disease leishmaniasis
Professor Gideon Wasserberg at UNC Greensboro has been awarded a prestigious $3.7 million National Institutes of Health R01 grant to advance his research on controlling sand flies, the vectors of the parasitic disease leishmaniasis.

NewsA microbial blueprint for climate-smart cows
Recent research has shown that feeding cows red seaweed can dramatically cut the amount of methane that is produced and released into the environment. A new study sheds light on that process and reveals which microbes in the cow’s gut might help reduce methane.

NewsHepatitis E virus from rats can also infect humans in individual cases – a new zoonotic pathogen?
It has only been known for a few years that humans can also be infected with a variant of the hepatitis E virus that is usually prevalent in rats. Following reports of individual cases, mainly from Hong Kong and Spain, the first infection with ratHEV has now also been described in a patient from Germany.

NewsPig disease vaccine effectiveness linked to T cell response
A new study shows that the effectiveness of current vaccines against porcine reproductive and respiratory syndrome virus (PRRSV) is due to the response of T cells against the disease, rather than the production of antibodies. The work is an important step in identifying specific targets for vaccines on a rapidly mutating virus.

NewsWild birds are driving the current U.S. bird flu outbreak
Researchers traced the introduction and spread of highly pathogenic H5N1 viruses during the first 18 months in North America using genomic sequencing and migratory flyway analysis, discovering that the viruses were spread primarily by wild migrating birds.

NewsNew test could allow for more accurate Lyme disease diagnosis
Researchers have developed a new way to detect the Lyme disease bacterium Borrelia burgdorferi, allowing for faster and more accurate diagnosis.

NewsManganese is Lyme disease bacterium’s double-edged sword
For decades, Lyme disease has frustrated both physicians and patients alike. Caused by the corkscrew-shaped bacterium Borrelia burgdorferi, the infection, if left untreated, can linger for months, leading to fever, fatigue and painful inflammation. Source: U.S. Centers for Disease Control and Prevention This digitally colorized scanning electron microscopic ...

NewsImaging reveals bacterial symbionts in the ovaries of tiny, aquatic crustaceans
Researchers have imaged a heritable form of bacterial symbiosis inside the reproductive system of tiny crustaceans known as ostracods. Bacteria from the genus Cardinium live inside the egg cells and tissues of ostracod ovaries, transmitted from mothers to offspring.

NewsRainfall and temperature shape mosquito fauna in Atlantic Forest bromeliads, including malaria vectors
Results from a study of mosquito larvae conducted in a natural area in the municipality of São Paulo (Brazil) may help estimate the effects of climate change on disease transmission risk in the biome.

NewsCracking leishmaniasis: new DNA test to track infection
A new study offers an innovative way to track the spread of leishmaniasis, a parasitic disease affecting both animals and humans. Researchers developed a fast, reliable method to identify sand fly species, detect Leishmania parasites, and determine the source of their blood meals from a single sample.

NewsMissing links for rabies in Peru highlights global threats of health inequity
Researchers found that efforts to track dog-related rabies in poorer areas of Peru’s second largest city were lacking even though more dogs were found to have the disease there than in wealthier neighborhoods.

NewsEgypt becomes the seventh country in the Eastern Mediterranean Region to eliminate trachoma as a public health problem
The World Health Organization (WHO) today announced that Egypt has successfully eliminated trachoma as a public health problem, marking a historic public health milestone for the country and WHO’s Eastern Mediterranean Region (WHO EMR).
