The pectoral girdle is a complex structure which varies in its morphology between species. A major component in birds is the furcula, which can be considered equivalent to a fusion of the paired clavicles found in many mammals, and the single interclavicle found in many reptiles. These elements are a remnant of the dermal skeleton and the only intramembranous bones in the trunk. Postnatally, the furcula plays important mechanical roles by stabilising the shoulder joint and acting as a mechanical spring during flight...

Despite the importance of gut microbiota for broiler performance and health little is known about the composition of this ecosystem, its development and response towards bacterial infections. Therefore, the current study was conducted to address the composition and structure of the microbial community in broiler chickens in a longitudinal study from day 1 to day 28 of age in the gut content and on the mucosa. Additionally, the consequences of a Campylobacter (C.) jejuni infection on the microbial community were assessed...

Salmonella enterica serovar Pullorum/Gallinarum is an important infectious pathogen that has caused widespread problems for chicken industry. Traditional Salmonella serotyping is an expensive and time-consuming process. In this study, we developed a rapid one-step polymerase chain reaction (PCR) method to identify S. Pullorum/Gallinarum. The PCR-based assay focuses on flhB, which shows a deficient region only in S. Pullorum/Gallinarum, compared with that of other serovars. The specificity and sensitivity of the PCR system were evaluated...

The use of antibiotics in farm management (growing crops and raising animals) has become a major area of concern. Its implications is the consequent emergence of antibiotic resistant bacteria (ARB) and accordingly their access into the human food chain with passage of antibiotic resistance genes (ARG) to the normal human intestinal microbiota and hence to other pathogenic bacteria causative human disease. Therefore, we pursued in this study to unravel the frequency and the quinolone resistance determining region, mecA and cfr genes of methicillin-susceptible Staphylococcus aureus (MSSA), methicillin-resistant S...

Ingestion of foreign bodies is common in clinical practice. Most ingested foreign bodies will pass through the gastrointestinal (GI) tract without any problems. While GI tract injury due to the ingested foreign body such as a toothpick, a fishbone, a date pit, or a chicken bone, is common, duodenal perforation is rare. In this report, our experience with this rare entity is shared. We present a 38-year-old male patient with GI tract perforation in the bulbus of the duodenum due to a leg of glasses. The patient was admitted to our hospital with severe abdominal pain...

The objective of this ring test was to investigate the prececal phosphorus (P) digestibility of soybean meal (SBM) in broiler chickens using the trial protocol proposed by the World's Poultry Science Association. It was hypothesized that prececal P digestibility of SBM determined in the collaborating stations is similar. Three diets with different inclusion levels of SBM were mixed in a feed mill specialized in experimental diets and transported to 17 collaborating stations. Broiler chicks were raised on commercial starter diets according to station-specific management routine...

The effects of in ovo injection of raffinose (RFO) as a prebiotic on growth performance, relative weight of proventriculus, gizzard, drumstick and breast muscles, and ileum mucosa morphology were examined in Cobb 500 broilers. A total of 240 fertilized eggs were divided into 4 groups: a non-injected with intact shell and 3 levels of RFO solution (1.5, 3.0, and 4.5 mg in 0.2 mL of an aqueous diluents). The RFO solution was injected into the air sac on d 12 of incubation. In total 144 birds were fed a standard diet and management and sacrificed at d 21 post hatch for collection of samples...

BACKGROUND: Newcastle disease (ND), caused by Newcastle disease virus (NDV), is a devastating disease of poultry and wild birds. ND is prevented by rigorous biocontainment and vaccination. One potential approach to prevent spread of the virus is production of birds that show innate resistance to NDV-caused disease. Induced pluripotent stem cell (iPSC) technology allows adult cells to be reprogrammed into an embryonic stem cell-like state capable of contributing to live offspring and passing on unique traits in a number of species...

Angiogenic capacity of biomaterials is a key asset to drive vascular ingrowth during tissue repair and regeneration. Here we design a unique angiogenic microcarrier based on sol-gel derived mesoporous silica. The microspheres offer a potential angiogenic stimulator, Si ion, 'intrinsically' within the chemical structure. Furthermore, the highly mesoporous nature allows the loading and release of angiogenic growth factor 'extrinsically'. The Si ion is released from the microcarriers at therapeutic ranges (over a few ppm per day), which indeed up-regulates the expression of hypoxia inducing factor 1α (HIF1α) and stabilizes it by blocking HIF-prolyl hydroxylase 2 (PHD2) in HUVECs...

Chicken eggshells (ES) as alkaline sorbent were immobilized in a fixed bed to remove typical heavy metals from acid mine drainage (AMD). The obtained breakthrough curves showed that the breakthrough time increased with increasing bed height, but decreased with increasing flow rate and increasing particle size. The Thomas model and bed depth service time model could accurately predict the bed dynamic behavior. At a bed height of 10 cm, a flow rate of 10 mL/min, and with ES particle sizes of 0.18-0.425 mm, for a multi-component heavy metal solution containing Cd(2+), Pb(2+) and Cu(2+), the ES capacities were found to be 1...

Necrotic enteritis (NE) is a major problem in antibiotic-free (ABF) chicken flocks and specific strains of Clostridium perfringens are known to induce NE. The objective of this study was to develop a chicken intestinal ligated loop model in order to compare the virulence of various C. perfringens strains recovered from consecutive ABF flocks with and without NE. Intestinal loops were surgically prepared in 10 anaesthetized specific-pathogen-free chickens and alternately inoculated with C. perfringens isolates or brain heart infusion (BHI) media...

Daniel Ricquier
The present text summarizes what was my contribution, starting in 1975, to the research on the uncoupling protein 1 (UCP1), the mitochondrial uncoupler of brown adipocytes. The research on UCP1 aimed at identifying the mechanisms of heat production by brown adipocytes that occurs in mammals either at birth or during cold exposure and arousal in hibernators. With others and in particular Dr. David Nicholls, I participated in the first experiments that contributed to the identification of UCP1. Important steps were the obtention of UCP1 antibodies followed with my main collaborator and friend Frédéric Bouillaud with the initial cloning of the UCP1 cDNA and gene from rats and humans...

Constant surveillance of live poultry markets (LPMs) is currently the best way to predict and identify emerging avian influenza viruses (AIVs) that pose a potential threat to public health. Through surveillance of LPMs from 16 provinces and municipalities in China during 2014-2016, we identified 3,174 AIV-positive samples and isolated and sequenced 1,135 AIVs covering 31 subtypes. Our analysis shows that H5N6 has replaced H5N1 as one of the dominant AIV subtypes in southern China, especially in ducks. Phylogenetic analysis reveals that H5N6 arose from reassortments of H5 and H6N6 viruses, with the hemagglutinin and neuraminidase combinations being strongly lineage specific...

A suitable analytical method is required to study the behaviour of florfenicol (FF) and its metabolite florfenicol amine (FFA) in broiler's feathers. An LC-MS/MS method was developed, assessed, and intralaboratory-validated for FF and FFA analyses. We chose cloramphenicol-d5 as an internal standard, acetone as a solvent for the extraction of the analytes and dichloromethane for the clean-up. Through LC-MS/MS analysis, we established a detection limit of 20 μg kg(-1), as well as a calculated quantification limit of 24...

Exposure to ochratoxin A (OTA) can lead to changes in global gene expression. This study investigated the individual expression of genes turned on and off in renal cells of chicks after different durations of exposure to dietary OTA. One hundred and eighty day-old male broiler chicks (Ross 308) were randomly assigned to a 3 × 3 factorial arrangement of treatments (3 levels of OTA: 0, 1 and 2 mg OTA/kg diet and 3 time periods: 7, 14 and 21 d). Birds were allocated to 36 pens (4 replicate pens of 5 birds each per treatment)...

Growth hormone (GH), or somatotropin, is a protein that may enhance physical performance and facilitate growth and wound healing. For this reason, growth hormones and their recombinant analogues are prohibited in human sports by the World Anti-Doping Agency (WADA) and in horseracing under Article 6 of the International Agreement on Breeding, Racing and Wagering published by the International Federation of Horse Racing Authorities (IFHA). Identifying the illicit use of GHs in both human athletes and racehorses is challenging, especially when differentiating between endogenous and exogenous GHs, and between analogues of GH from different species...

Excess phosphorus (P) in peri-urban regions is an emerging issue, whereas there is global depletion of quality mined supplies of P. The flow of P across the landscape leading to regional surpluses and deficits is not well understood. We computed a regional P budget with internal P flows in a fairly discreet peri-urban region (Lower Fraser Valley, BC) with closely juxtaposed agricultural and non-agricultural urban ecosystems, in order to clarify the relationship between food production, food consumption and other activities involving use of P (e...

Macrophages play important roles in mediating virus-induced innate immune responses and are thought to be involved in the pathogenesis of bacterial superinfections. The innate immune response initiated by both low pathogenicity AIV and bacterial superinfection in their avian host is not fully understood. We therefore determine the transcripts of innate immune-related genes following avian H9N2 AIV virus infection and E. coli LPS co-stimulation of avian macrophage-like cell line HD11 cells. More pronounced expression of pro-inflammatory cytokines (IL-6 and IL-1β) as well as the inflammatory chemokines (CXCLi1 and CXCLi2) was observed in virus infected plus LPS treated HD11 cells compared to H9N2 virus solely infected control...
