Biofilm formation, virulence and antimicrobial resistance of different Campylobacter jejuni isolates from a poultry slaughterhouse.

Biofilm formation, virulence and antimicrobial resistance of different Campylobacter jejuni isolates from a poultry slaughterhouse. Food Microbiol. 2019 Oct;83:193-199 Authors: García-Sánchez L, Melero B, Jaime I, Rossi M, Ortega I, Rovira J Abstract The fastidious requirement of the zoonotic pathogen Campylobacter jejuni contrasts with its ability to overcome harsh conditions. Different strategies might be involved in the survival and persistence of C. jejuni through the poultry food chain. Therefore, the aims of this study were to get insights in the survival strategies in the poultry slaughterhouse environment by (i) characterizing factors such as biofilm formation, virulence and antimicrobial resistance in environmental isolates and (ii) understanding the possible link between the phenotypic and genetic characterization using whole genome sequencing (WGS). Results have shown that three STs: ST 443 (PFGE A), ST 904 (PFGE C) and ST 3769 (PFGE G), out of the six studied, formed biofilms with variable intensity according to different conditions (temperatures -37 °C, 30 °C, 25°C- and materials -stainless steel and plastic-). High levels of antimicrobial resistance were found in isolates to ciprofloxacin, nalidixic acid and tetracycline as well as to two common detergents used in the slaughterhouse. A combination of several changes in the genome of ST 904 (PFGE C) including mutations, insertions in antimicrobial resistance gen...

Source: European Union, European Centre for Disease Prevention and Control (ECDC). Published: 5/28/2019. This 25-page report presents the results of the third round of the external quality assessment on antimicrobial susceptibility testing for national public health laboratories for Campylobacter (Campylobacter EQA3-AST) within the Food- and Waterborne Diseases and Zoonoses Network (FWD-Net). It is part of a European Union protocol for harmonized monitoring of antimicrobial resistance in human Salmonella and Campylobacter isolates. Campylobacteriosis, followed by salmonellosis, is the leading cause of zoonotic foodborne d...

Conclusion This study confirms the in vitro antibacterial activity of BIOCITRO® against Gram-negative and Gram-positive bacteria. For most of the strains, the product reached the bactericidal effect at the same concentration of the bacteriostatic effect and maximum difference between MIC and MBC was two dilution steps. The less susceptible species of the study were S. enterica ssp. enterica and E. coli with MBC90 values of 256 and 128 μg/mL, respectively, while the most susceptible was C. perfringens with MBC90 of 16 μg/mL. After short exposition time to the product, the significant effect over the viability of ...

In conclusion, association rule mining is an effective tool for identifying patterns of multidrug resistance within antimicrobial susceptibility testing data and evaluating the statistical and biological significance of the patterns. Rule quality measures used to sort and differentiate rules should be tested using resampling procedures to minimize the false discovery rate. Rule mining identified consistent multidrug resistance patterns involving beta-lactams, sulfisoxazole, tetracycline, gentamicin, and streptomycin in E. coli isolated from chicken carcasses and meat between 2004 and 2012. The generally low rule overlap su...

The risk of reintroducing previously eradicated animal diseases into the European Union is omnipresent as considerable amounts of food products of animal origin (POAO) from endemic countries are continuously imported legally and illegally into the EU. Additionally, these pr...

ute;nguez L Abstract Consumers require safety foods but without losing enough supply and low prices. Food concerns about antimicrobial residues and antimicrobial-resistant (AMR) bacteria are not usually appropriately separated and could be perceived as the same problem. The monitoring of residues of antimicrobials in animal food is well established at different levels (farm, slaughterhouse, and industry), and it is preceded by the legislation of veterinary medicines where maximum residues limits are required for medicines to be used in food animal. Following the strategy of the World Health Organization, one of th...

The objective of this review is to provide a complete report of the prevalences of AMR among zoonotic bacteria that present the greatest threats to NHP, occupational, and public health. High prevalences of AMR exist among Shigella, Campylobacter, and Yersinia, including resistance to antimicrobials important to public health, such as macrolides. Despite improvements in regulations, standards, policies, practices, and zoonotic awareness, occupational exposures to and illnesses due to zoonotic pathogens continue to be reported and, given the documented prevalences of AMR, constitute an occupational and public health risk. Ho...
