Article Synopsis
- Bovine viral diarrhoea (BVD) is a significant economic threat to livestock due to its complex transmission and diverse pestiviruses (BVDV-1, -2, and HoBi-like pestivirus), prompting eradication plans in several countries, including France since 2019.
- A study collected 1,037 BVDV-positive cattle samples in France from 2011 to 2023, revealing that two main BVDV-1 genotypes (1e and 1b) make up 88% of the sequences, with other less common genotypes also identified.
- Phylogenetic analysis showed different global distribution patterns for the main genotypes, but their relative frequencies have remained stable in France since
is a major aetiological agent of bovine respiratory disease worldwide. Genome-based analyses are increasingly being used to monitor the genetic diversity and global distribution of , complementing existing subtyping schemes based on locus sequencing. However, these analyses have so far provided limited information on the spatiotemporal and population dynamics of circulating subtypes.

We conducted a descriptive study to investigate EP prevalence and spatial distribution in an endemic region: the Camargue and the Plain of La Crau in France. In spring 2015 and 2016, we carried out sampling at stables (total n = 46) with a history of horses presenting chronic fever or weight loss.

- Q fever is a disease caused by the bacteria Coxiella burnetii that primarily affects ruminant animals and can be transmitted to humans through inhalation of contaminated aerosols.
- * The study aimed to analyze dust samples from various farm buildings to assess the presence and amount of C. burnetii, especially in relation to cases of abortions in animals, which may indicate Q fever outbreaks.
- * Results indicated that C. burnetii DNA was more frequently detected on sheep and goat farms compared to cattle farms, suggesting that these environments could serve as indicators of possible contamination.
Q fever is a worldwide zoonosis caused by the bacterium Coxiella burnetii. In domestic ruminants, Q fever main clinical manifestations are abortions. Although the clinical signs may differ between ruminant species, C.
