Genetic analyses shed light on the origin of the small hive beetle recently reported on Reunion Island

The small hive beetle is a parasite of honey bees. It was first detected on Reunion Island in July 2022. Genetic analyses conducted by ANSES's Sophia Antipolis Laboratory have revealed that the specimens that arrived on the island are similar to those found in China and the Philippines.

"One Health" collaboration on a bacterium with multiple resistance to antibiotics in horses

Scientists from ANSES, the Dynamicure joint research unit (Inserm/Universities of Caen and Rouen) and Caen University Hospital recently joined forces to study Klebsiella pneumoniae , a bacterium that is pathogenic to humans and horses. By analysing strains of K. pneumoniae collected from horses over a period of almost 30 years, they found a wide diversity of strains, some with increased antibiotic resistance

A method for tracking the spread of a new Campylobacter species

ANSES has developed a method for culturing Campylobacter hepaticus. Cases of poultry becoming infected with this bacterium have increased in France since 2019. Culturing it should provide an opportunity to track its spread on farms through genetic characterisation.

Contaminant detection: a new score to assess the performance of testing laboratories

Scientists at ANSES have created a new score for statistically assessing the detection capabilities of testing laboratories. This score can be used when it is necessary to verify the ability of laboratories to detect a contaminant such as a pathogen or chemical in a sample.
Transmission of pathogens between pollinators

Transmission of pathogens between pollinators

A study carried out in eight European countries confirms that pathogens can be transmitted from one species of pollinating insect to another. The health of wild pollinators can therefore be affected when a contaminated colony of honeybees is established nearby. Unlike in previous studies, the results did not show any significant effect of the type of crop grown in bee foraging areas.

Discovery of triple resistance to antiparasitic drugs in equines

For the first time in France, a single farm has been found infested with digestive parasites known as cyathostomins, or small strongyles, resistant to all three classes of antiparasitic drugs authorised for equines. They were discovered as part of a study carried out by an ANSES team on a racehorse stud farm.

Towards the integrated surveillance of antimicrobial resistance

Bacterial resistance to antibiotics is a major health problem for both humans and animals. In France, the use of antibiotics and the distribution of resistant bacteria are covered by several surveillance schemes that do not consistently or sufficiently collaborate with one another. The Surv1Health project, which has just been completed, aimed to identify ways of breaking down silos in the surveillance of antimicrobial resistance and making it more useful as part of the ‘One Health’ approach.

Vector-borne diseases: a concern for cattle health

The common factor linking bluetongue, epizootic haemorrhagic disease, besnoitiosis, etc. is that they are all caused by pathogens transmitted to ruminants by arthropods such as ticks, midges or mosquitoes. ANSES has funded a review of studies carried out in metropolitan France, which highlighted the many gaps in current knowledge about the vectors found on cattle farms and the pathogens they can transmit. Such knowledge is nevertheless essential given current global changes, which are having an impact on vector distribution and therefore on the epidemiology of vector-borne diseases in livestock.

Approval of water analysis laboratories: a joint ANSES/OFB portal

On 25 March 2024, ANSES and the French Biodiversity Agency (OFB) inaugurated a joint portal to provide access to both of their information systems dedicated to applications for the approval of water analysis laboratories. The OFB handles environmental approvals and ANSES handles water quality monitoring approvals.

The main Mycoplasma bovis subtype in France actually conceals two lineages

A study of Mycoplasma bovis , a bacterium that is pathogenic for cattle, has revealed the presence of two lineages in France, whereas the population of bacteria of the main circulating subtype was previously thought to be homogeneous. This discovery will help improve surveillance of this bacterium.
