NewsScientists blame climate change for spread of infectious diseases and unleashing of ice-locked microbes in Arctic
Climate change is creating new pathways for the spread of infectious diseases like brucellosis, tularemia, or E. coli in the Arctic, according to a broad international consortium of scientists.

NewsHantavirus in Madagascar linked to black rats in agricultural areas
A new study reveals that the black rat is likely responsible for transmitting deadly hantaviruses in rural Madagascar, where forested landscapes have been converted to agriculture and settlements.

NewsAlternative approach to Lyme disease vaccine development shows promise in pre-clinical models
An international research team finds genetically engineered Lyme bacterial proteins could offer long-standing protection against infection while requiring fewer vaccinations.

NewsAMI members develop rapid test for bacterium that costs poultry industry billions globally
Scientists have developed a rapid, sensitive and specific test for a bacterial pathogen that is responsible for necrotic enteritis in poultry, a disease that causes billions in global economic losses annually.

NewsHow a small number of mutations can fuel outbreaks of western equine encephalitis virus
New research shows how small shifts in the molecular makeup of a virus can profoundly alter its fate. These shifts could turn a deadly pathogen into a harmless bug or supercharge a relatively benign virus, influencing its ability to infect humans.

NewsNew carrier birds brought avian flu to Europe, Americas
Unexpected wild species, from pelicans to peregrine falcons, are transporting the virus from poultry farms to new places around the world and changing where the risk of outbreaks is highest.

NewsMuseum collections reveal worldwide spread of butterfly disease
A new study of museum butterfly collections explore how these specimens can be used to track the spread of disease. Ophryocystis elektroscirrha (OE) is a protozoan parasite that can hamper a butterfly’s growth and flight.

NewsPinning down the process of West Nile virus transmission
A US project aims to use mathematical models to analyze how factors like temperature, light pollution, and bird and mosquito abundance affect West Nile virus transmission. The ultimate goal is to advise health departments of the best time of year to kill the bugs.

NewsHidden virus harboured by fruit flies may influence experimental accuracy
A new study suggests the presence of Nora virus in laboratory strains of Drosophila fruit flies influences their resilience to stress and bacterial infection and can confound experimental studies of ageing.

NewsScreening tool tests bee colonies by mimicking pheromones of death
A screening tool tests colonies for hygienic behavior by mimicking the pheromones emitted by sick or dying bees. The test can identify colonies resistant to several pests and pathogens that can decimate bee populations such as Vairimorpha (known to many beekeepers as Nosema) and fungal infections including chalkbrood.

NewsResearchers design genetic tools to develop vaccines more efficiently for African swine fever virus (ASFV)
A synthetic genomic-based reverse genetics tool has been developed for African swine fever virus (ASFV) that helps vaccine development to reduce the economic losses. The system may also be adapted to other emerging viral threats.

NewsHow Zika virus knocks out our immune defenses
Scientists have made striking discoveries regarding the different infection mechanisms of Zika and dengue virus of the same viral family. These understandings pave the way for vaccine development to combat flaviviruses with similarities.

NewsResearchers find live hantavirus is carried in various New Mexico small mammal species
A study was carried out to find out the reasons why human cases of the sin nombre hantavirus were concentrated in one particular region of New Mexico, even though the virus was found in 30 species of rodents and small mammals endemic to a different region.

NewsSusceptibility to bovine TB in cattle traced to key genes
A new study identifying genetic factors contributing to bovine tuberculosis (bTB) susceptibility has found several key genes and pathways involved in the bovine response to Mycobacterium bovis, the causative agent of the disease in cattle.

NewsInfluenza of avian origin confirmed in a sheep in Yorkshire
The UK’s Chief Veterinary Officer has confirmed a case of influenza of avian origin (H5N1) in a single sheep in Yorkshire following repeat positive milk testing.

NewsBartonella and babesia found in brain tissue of child with seizures
In a new case study, researchers have found Bartonella henselae, Babesia odocoilei and Babesia divergens-like MO-1 DNA in brain tissue samples from a young child with seizures and suspected Rasmussen’s encephalitis.

NewsResearchers test new, more reliable method to detect chagas disease
Researchers have successfully tested a faster, more sensitive and reliable way to diagnose Chagas disease, a debilitating parasitic illness that affects approximately 6 million people worldwide.
-
NewsHidden threat: The evolving fungus that spreads through cats and humans
Researchers have developed a better understanding about the molecular basis of the Sporothrix species in virulence and evolution, amid the largest sporotrichosis epidemic in Brazil. The identification of the genetic markers helps to enhance fungal surveillance and strengthen disease control.

NewsH5N1 influenza viral lineages beginning to evade human immunological defenses
A new computer modelling approach predicts the protein-antibody interactions of the potentially pandemic-causing H5N1 avian influenza virus lineage. It helps to understand the viral evolution to ensure high vaccine efficacy.

NewsResearchers discover Achilles heel of Lyme disease pathogen
Researchers discovered and investigated an unique enzyme used in the pathway specific to Borrelia burgdorferi, the parasite that causes Lyme disease. The enzyme serves as the ideal genus-specific target for therapeutic intervention.
