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).

NewsFirst detection of zoonotic Rickettsia species in dog ticks from Malawi reveals potential public health risk
An international research team has reported the first molecular detection of Rickettsia bacteria in ticks collected from domestic dogs in Malawi, addressing a significant knowledge gap in understanding tick-borne disease risks in southeastern Africa.

NewsResearchers capture first high-res images of deadly yellow fever virus
Researchers have captured the first high-resolution images of the yellow fever virus (YFV), a potentially deadly viral disease transmitted by mosquitoes that affects the liver.

NewsNew study reveals not all bats carry equal viral risk
A groundbreaking study sheds new light on the relationship between bats and dangerous viruses, showing that contrary to widespread assumptions, not all bats carry viruses with high epidemic potential, only specific groups of species.

NewsAntimicrobial peptides can reduce salmonella in chickens
A new study has found that antimicrobial peptides can combat Salmonella infections in chickens, a major cause of foodborne disease in the U.S. This discovery could help improve food safety and protect public health without relying on antibiotic use.

NewsAI and citizen science reveal potential first detection of invasive malaria mosquito in Madagascar
Researchers used AI and citizen science to identify what may be the first Anopheles stephensi mosquito ever detected in Madagascar — a species capable of spreading deadly malaria across urban Africa. A single smartphone photo submitted through NASA’s GLOBE Observer app led to the discovery.

NewsViral infections at the heart of why honey bees overthrow their queen
Common viral infections shrink a queen bee’s ovaries, reducing both her egg-laying capacity and her production of methyl oleate, a pheromone that normally keeps worker bees loyal. When methyl oleate levels drop, workers will “smell” the queen’s weakness - and begin preparing her successor.

NewsWarmer Nordic springs double the incidence of avian malaria
A unique long-term study, in which biological samples were collected from the same population of blue tits over a 30-year period, shows that rising spring temperatures have doubled the incidence of avian malaria in southern Sweden.

NewsStudy uncovers origins of urban human-biting mosquito, shedding light on uptick in West Nile virus spillover from birds to humans
The research disproves the theory that the mosquito evolved in the London underground by dating the mosquito’s origin back over 1,000 years and identifies the genetic links between bird-biting and human-biting mosquitoes, key to West Nile transmission.

NewsAfter injuries, carpenter ants use amputation to stop potential infections from spreading
Carpenter ants are not squeamish when it comes to caring for the wounded. To minimise the risk of infection, the insects immediately amputate injured legs – thereby more than doubling their survival rate.
