In pig production, the widespread conventional indoor system with a slatted floor currently dominates. However, this production is becoming less socially acceptable. addition to general environmental protection issues, animal welfare, absence of suffering and distress, management pain also constitute societal concerns. context, alternative systems are gaining ground. Although they popular consumers other citizens, these have their critical points. Here, we reviewed international scientific...
We report the first and only case of a porcine epidemic diarrhea (PED) outbreak occurring in December 2014 northern France, we show using full-length genome sequence French PED virus (PEDV) isolate that it was PEDV indel strain close to German strains recently isolated.
This report describes the work developed during execution of Review Impact MICrobiome In Assesment (RIMICIA) project. project has performed a comprehensive and critical assessment evidence-based research about: i) impact dietary compounds in human some domestic animals (i.e., poultry, ruminants pigs) gut microbiome; ii) most representative vitro vivo models microbiota currently used microbiome studies; iii) methodology to measure changes microbiota. also gathered appraised information about...
A triplex real-time PCR assay to quantify Mycoplasma hyopneumoniae in specimens from live and dead pigs was developed validated. The minimal dose of Myc. required induce pneumonia specific pathogen-free determined.This TaqMan test simultaneously detected three genes encoding the proteins P46, P97 P102. All strains analysed were detected, including isolated countries (France, England Switzerland) several pig farms (n = 33), specific. estimated detection thresholds 1.3 genome equivalents...
A new multiplex qPCR, targeting Mycoplasma (M.) hyopneumoniae, M. hyorhinis and flocculare, was developed the relationship between detection of those mycoplasma species extent gross pneumonia-like lesions in slaughtered pigs lungs were investigated.The qPCR method targets p102, p37 fruA genes has limits 14, 146 16 genome equivalents μl-1 for respectively. In all, 671 collected analysed, among them 666 scored macroscopic pneumonia categorized according to (no or minor lesions, moderate...
Infection by Toxoplasma gondii postnatally can occur after ingestion of contaminated meat or water (tissue cysts/oocysts). In Europe, percentage borne infections is estimated between 30 and 63 %, out which pork makes the most important source. The aim this study was to (i) investigate seroprevalence T. in intensive pig farms from western France; (ii) identify risk factors associated with seropositivity.Data were collected November 2006 February 2008 60 farrow-to-finish farms, where sera...
This report describes the detection of a triple reassortant swine influenza A virus H1avN2 subtype. It evolved from an avian-like H1avN1 that first acquired N2 segment seasonal H3N2, then M 2009 pandemic H1N1, in two reassortments estimated to have occurred 10 years apart. study illustrates how recurrent infections increase co-infection risk and facilitate evolutionary jumps by successive gene exchanges. recalls importance appropriate biosecurity measures inside holdings limit persistence...
In order to assess influenza D virus (IDV) infections in swine France, reference reagents were produced specific pathogen free pigs ensure serological and virological analyses. Hemagglutination inhibition (HI) assays carried out on 2090 domestic pig sera collected 2012–2018 102 farms. Only 31 from breeding sows sampled 2014–2015 six farrow-to-finish herds with respiratory disorders contained IDV-specific antibodies. two of them, within-herd percentage positive samples (73.3% 13.3%,...
Mycoplasma hyorhinis and M. flocculare are commonly co-isolated with hyopneumoniae (primary agent of swine enzootic pneumonia) in gross pneumonia-like lesions, but their involvement the disease process remains unknown. T cells play an immuno-pathological role during mycoplasmal infections. Dendritic (DCs) major antigen-presenting involved cell activation differentiation. In this study, we investigated cytokine (IL-6, IL-8, IL-10, IL-12, TNF-α) production by porcine bone-marrow-derived DCs...
