Antimicrobial resistance and genetic diversity of strains from different clinical sources in horses.

Introduction: is a major cause of infections and reproductive disorders among horses, ranked in recent French studies as the sixth most frequently isolated bacterial pathogen in equine clinical samples. The proportion of multidrug-resistant (MDR) is therefore significant in a context where MDR strains are considered a major global concern by the World Health Organization.

Methods: In this study, we used a genomic approach to characterize a population of 119 equine strains collected by two laboratories specialized in animal health in Normandy (France).

Factors Associated with Owner-Reported Euthanasia in Equids in France.

There is limited evidence regarding the proportion of dead equids in France that were euthanized and the factors influencing the decision-making of euthanasia. The better understanding of which could facilitate research on improvement of welfare, especially on end of life issues. The aim of this study was to estimate the proportion of euthanasia and identify associated factors in equids in France.

Relationship between rifampicin resistance and RpoB substitutions of Rhodococcus equi strains isolated in France.

Objectives: Study of the rifampicin resistance of Rhodococcus equi strains isolated from French horses over a 20-year period.

Methods: Rifampicin susceptibility was tested by disk diffusion (DD) and broth macrodilution methods, and rpoB gene sequencing and MLST were performed on 40 R. equi strains, 50.

Compilation of 29 years of postmortem examinations identifies major shifts in equine parasite prevalence from 2000 onwards.

Horses are infected by a wide range of parasite species that form complex communities. Parasite control imposes significant constraints on parasite communities whose monitoring remains, however, difficult to track through time. Postmortem examination is a reliable method to quantify parasite communities.

Identification of levers for improving dead equine traceability: A survey of French equine owners' perception of regulatory procedures following their animal's death.

The core of the French equine traceability system is the census database (SIRE) managed by the French horse and riding institute (IFCE). Following the death of an equine, owners are legally obliged to take charge of cadaver removal by contacting a rendering company directly or after registration on the national ATM-équidés ANGEE association (ATM) website, which proposes negotiated prices for removal and recording of the death in the SIRE database. Despite these offers, ATM notes few users.
