Cliniquement, c'est...
Virus de la grippe du porc et risque d’infection chez les travailleurs de l’industrie du porc
La grippe du porc est une maladie virale respiratoire aiguë et très contagieuse qui se propage par les aérosols, et par contacts directs ou indirects avec des animaux malades ou porteurs asymptomatiques. Des flambées de grippe ont lieu tout au long de l'année 2016 chez les porcs, avec une incidence accrue à l'automne et en hiver dans les zones tempérées. Le porc peut aussi être infecté simultanément par des virus influenza humains et aviaires, ce qui donne la possibilité au matériel génétique...
Comparative study on exposure of workers and bystanders during pest control of the Oak Processionary Moth by spray application
Biocidal products used for spray application against the oak processionary moth (OPM) require authorisation in accordance with Regulation (EU) No. 528/2012 of the European Parliament for that use. For authorisation, a risk assessment based on exposure estimation is performed for all intended uses of the respective product. Detailed information on the application process and the resulting exposure of operators and of bystanders was lacking until now. It is expected that the main routes of exposure are dermal and inhalation. Spray applications carried out for control of OPM show significant differences...

Occupational exposure levels of bioaerosol components are associated with serum levels of the acute phase protein Serum Amyloid A in greenhouse workers
BACKGROUND: Occupational exposure to particles may be associated with increased inflammation of the airways. Animal experiments suggest that inhaled particles also induce a pulmonary acute phase response, leading to systemic circulation of acute phase proteins. Greenhouse workers are exposed to elevated levels of bioaerosols. The objective of this study is to assess whether greenhouse workers personal exposure to bioaerosol components was associated with serum levels of the acute phase proteins Serum Amyloid A (SAA) and C-reactive protein (CRP). METHODS: SAA and CRP levels were determined in serum...
