Antibiotics Resistance in Enterococcus Isolates from Poultry Waste

2020

Abstract The aim of the study was to evaluate the drug resistance of Enterococcus faecalis and Enterococcus faecium isolated from different types of poultry waste. The study material consisted of feather samples (duck, turkey, chicken), sludge and centrifuge sediment, originating from three poultry farms. The study was conducted in two stages; isolation and identification of Enterococcus bacteria from the waste and evaluation of their drug resistance using Kirby-Bauer method. Contamination of the poultry waste with Enterococcus isolates included E. faecium species (79 %) and E. faecalis (21 %). The most contaminated were sludge and sediment from the centrifuge as well as chicken feathers, i…

Effects of a Lactobacillus salivarius mixture on performance, intestinal health and serum lipids of broiler chickens

2017

The ban or severe restriction on the use of antibiotics in poultry feeds to promote growth has led to considerable interest to find alternative approaches. Probiotics have been considered as such alternatives. In the present study, the effects of a Lactobacillus mixture composed from three previously isolated Lactobacillus salivarius strains (CI1, CI2 and CI3) from chicken intestines on performance, intestinal health status and serum lipids of broiler chickens has been evaluated. Supplementation of the mixture at a concentration of 0.5 or 1 g kg-1 of diet to broilers for 42 days improved body weight, body weight gain and FCR, reduced total cholesterol, LDL-cholesterol and triglycerides, inc…

Host and environmental factors affecting the intestinal microbiota in chickens

2018

The initial development of intestinal microbiota in poultry plays an important role in production performance, overall health and resistance against microbial infections. Multiplexed sequencing of 16S ribosomal RNA gene amplicons is often used in studies, such as feed intervention or antimicrobial drug trials, to determine corresponding effects on the composition of intestinal microbiota. However, considerable variation of intestinal microbiota composition has been observed both within and across studies. Such variation may in part be attributed to technical factors, such as sampling procedures, sample storage, DNA extraction, the choice of PCR primers and corresponding region to be sequenc…

Multi-criteria framework as an innovative tradeoff approach to determine the shelf-life of high pressure-treated poultry

2016

International audience; A multi-criteria framework combining safety, hygiene and sensorial quality was developed to investigate the possibility of extending the shelf-life and/or removing lactate by applying High Hydrostatic Pressure (HHP) in a ready-to-cook (RTC) poultry product. For this purpose, Salmonella and Listeria monocytogenes were considered as safety indicators and Escherichia coli as hygienic indicator. Predictive modeling was used to determine the influence of HHP and lactate concentration on microbial growth and survival of these indicators. To that end, probabilistic assessment exposure models developed in a previous study (Lerasle, M., Guillou, S., Simonin, H., Anthoine, V.,…

Extra-Intestinal Fluoroquinolone-Resistant Escherichia coli Strains Isolated from Meat

2018

Extra-intestinal E. coli are emerging as a global threat due to their diffusion as opportunistic pathogens and, above all, to their wide set of antibiotic resistance determinants. There are still many gaps in our knowledge of their origin and spread pathways, although food animals have been adjudicated vehicles for passing mult-drug resistant bacteria to humans. This study analyzed 46 samples of meat purchased from retail stores in Palermo in order to obtain quinolone-resistant E. coli isolates. Strains were screened for their phylogenetic groups, ST131-associated single nucleotide polymorphisms (SNPs), and then typed by ERIC-PCR. Their set of virulence factors, namely, kpsMII, papA, sfaS, …

Evidence for Human Adaptation and Foodborne Transmission of Livestock-Associated Methicillin-Resistant Staphylococcus aureus

2016

We investigated the evolution and epidemiology of a novel livestock-associated methicillin-resistant Staphylococcus aureus strain, which colonizes and infects urban-dwelling Danes even without a Danish animal reservoir. Genetic evidence suggests both poultry and human adaptation, with poultry meat implicated as a probable source.

Personality and meat consumption: The importance of differentiating between type of meat

2018

Recent research has shown that sociodemographic factors and the Big Five personality traits are related to people's overall level of meat consumption. However, there are important differences among various types of meat (e.g., red meat, poultry, and fish) that might lead to differential patterns in how the consumption of specific types of meat is associated with personality and sociodemographic factors. To disentangle these general and specific relationships, we conducted two studies using two large-scale representative samples from different countries: Germany (N = 13,062) and Australia (N = 15,036). Mostly consistent with our expectations, personality and sociodemographic variables showed…

Limited survey for the occurrence of aflatoxins in cereals and poultry feeds from Rabat, Morocco

2007

Fifty eight (58) samples of cereals for human consumption (20 corn flour, 17 wheat flour) and poultry feeds (n=21) purchased from popular markets of Rabat in Morocco were analyzed for aflatoxins (AF) by HPLC with immunoaffinity column (IAC) clean-up and fluorimetric detection. The incidence of AF in corn, wheat flour and poultry feeds was about 80, 17.6 and 66.6% respectively. High contamination levels were found in corn and poultry feeds samples. Levels of contamination of analyzed samples with AFB1 ranged from 0.23 to 11.2, 0.03 to 0.15 and 0.05 to 5.38 ng/g for corn, wheat and poultry feeds respectively. Results showed also that the contamination of 10% of samples of corn was higher than…

Évaluation des risques relatifs aux mesures de décontamination et de gestion des sous-produits animaux lors des cas de botulisme bovin et aviaire

2022

Le botulisme est une maladie neurologique humaine et animale, le plus souvent d’origine alimentaire, provoquée par l’action de neurotoxines bactériennes (toxines botuliques) produites par la bactérie Clostridium botulinum et qui se manifeste par une paralysie flasque pouvant aller jusqu’à la paralysie respiratoire et l’arrêt cardiaque. Neuf types toxiniques, répartis en une quarantaine de sous-types, sont actuellement connus.En France, le botulisme animal affecte essentiellement les oiseaux (sauvages et domestiques) et les bovins. Chez les volailles, on recense annuellement vingt à trente foyers, majoritairement dus aux types mosaïque C/D (élevages de poulets de chair et de dindes) suivi de…
