02/06/2014 Coxiella burnetii infection in dairy cattle herds - increased risk associated with contiguity between herds and animal purchases

Infection with Coxiella burnetii (Cb), the agent responsible for Q fever (for Query fever), occurs mainly after inhalation of aerosols contaminated by ruminant excreta. The spread of Cb between ruminant herds may result from transmission due to contiguity between herds and/or the introduction of infected excretory animals into healthy herds. Infection control strategies (vaccination, pre-sale testing of animals, ...) should be adapted to the predominantly identified route of transmission.

2014/04/16 A fruitful collaboration with the Pasteur Institute - Ixodes ricinus as a vector of the lyme disease agent

In our research unit, ticks, and especially the european tick Ixodes ricinus, are a central research subject. I. ricinus is indeed the vector of numerous pathogens for human as well as livestock. The understanding of fondamental mechanisms concerning the transmission of these pathogens as well as their interactions with the vector are key aspects for these vector-borne pathogens.

08/03/2013 Bovine Neonatal Pancytopenia update

Oniris CHV Since 2006, a new syndrome called Bovine Neonatal Pancytopenia (BNP) has appeared in different European countries (Théron et al., 2010). Although the pathophysiological mechanisms are now better understood thanks to recently published work (Foucras et al., 2011, Deutskens et al., 2011) and recent epidemiological studies reinforce the hypotheses put forward (Sauter-Louis et al., 2011), many unknowns remain. An epidemiological investigation is currently under way in the EPID team of the UMR BioEpAR to determine the risk factors for the occurrence of the disease at both individual and herd level. This is a case-control survey conducted jointly in France (EPID team coordination), Germany, the Netherlands and Belgium, coordinated by the Royal Veterinary College of London. This study is being carried out with the financial support of Pfizer SA. The objectives of the study are to determine the risk factors of the disease at farm and animal level, to determine the risk factors of low incidence (1 or 2 cases) versus high incidence (several cases) at farm level, and to investigate the prevalence of sub-clinical animals in affected farms. The recruitment phase has now been completed (after recruitment of 196 cases from 169 farms), and analyses are in progress.
