SESSIONS

1. Interactions between hosts, Microbiota and Salmonella

Philippe VELGE (France) and Andreas J. BAUMLER (United States of America)

Salmonella is a facultative intracellular bacterium found within a variety of phagocytic and non-phagocytic cells and able to infect a large variety of hosts belonging to the animal and plant kingdoms. In recent years, our vision of Salmonella host cell interaction has considerably evolved. The new paradigm is that Salmonella can enter cells through a variety of invasion factors and cannot only lie in a vacuole but can also evade into the cytosol. Moreover, its virulence potential varied according to the host microbiota. The first aim of this session is thus to show the evolution of Salmonella-host cell interaction paradigms by summarizing the different strategies used by Salmonella serotypes to invade and proliferate into eukaryotic cells. The second aim is to analyze the cross talk between Salmonella, its hosts, and the corresponding microbiota.

 

2. Ecology and epidemiology along the food chain

Marianne CHEMALY (France) and Antonia RICCI (Italy)

Epidemiological investigations for sampling and tracing Salmonella contamination throughout the food chain is the main focus of this session which covers the contamination of the food chain by Salmonella, from farm to fork. Communications addressed to this session should deal with the contamination and follow-up of animals or plants at the primary production level, the contamination during processing and at the retail level. Communications covering emerging serovars in domestic and wild animals, or covering novel aspects of Salmonella ecology in animals or humans are also welcomed in this session.

 

3. Risk assessment and control

Jean-Christophe AUGUSTIN (France) and Régis POUILLOT (Unites States of America)

This session is dedicated to communications dealing with the study of risk associated with the contamination of food by Salmonella and with measures implemented to control the risk. Communications should cover any of the following fields: exposure assessment, risk characterization, risk management, risk-based metrics (ALOP, FSO, PO), microbiological criteria and source attribution. Communications dealing with tools used in quantitative risk assessment (e.g., predictive microbiology, variability / uncertainty, mathematical modelling, dose-response modelling, and statistical inference, decision support tools) are also welcome.

 

4. Antimicrobial resistance

Axel CLOECKAERT (France) and Vincent BURRUS (Canada)

 

5. Whole Genome Sequencing

François-Xavier WEILL (France) and Alison MATHER (United Kingdom)

Over the last decade, high throughput whole-genome sequencing has revolutionized Salmonella genomics. This session is therefore dedicated to the use of whole genome sequencing in particular for:

1- comparative genomics, population structure, and phylodynamics of emerging and/or multidrug resistant Salmonella populations,

2- surveillance and investigation of Salmonella infections.

Communications can cover any of the following fields: bioinformatics infrastructure and analysis tools, genomic data and nomenclature, feasibility studies, compatibility with current typing and subtyping methods.


6. Detection and Characterization

Anne BRISABOIS (France) and Burkhard MALORNY (Germany)

Traditional cultivation, isolation and serotyping as well as molecular detection, identification and strain characterization will be the scope of the session entitled ‘Detection and Characterization’. Since their early development in the first half of the 20th century, conventional cultivation, serotyping and phage typing methods allowed long-term epidemiological surveillance and characterization of most Salmonella isolates issuing from routine analyses. However, with a public health objective, the ever-increasing safety criteria requested by the food chain actors and stakeholders, alternative methodologies popped up aiming at detecting, identifying and quantifying Salmonella in a fast, robust and traceable way and are continuously evolving. Numerous molecular characterization methods able to substitute or to complement traditional serotyping and sub-typing literally exploded during the last 25 years. Some alternative fingerprinting approaches reach or overtake classical methods in terms of sensitivity, some of them allow contamination and outbreak tracing, others allow sound phylogenetic analyses to be conducted. PCR-based methods significantly reduced the time required to detect and quantify Salmonella in various raw or pre-enriched matrices. During this session, novel and alternative methodologies for Salmonella detection and characterization will be explored except those based on whole genome sequencing (session ‘Genomic and applications’).

 

7. Epidemiology and Public Health

Nathalie JOURDAN DA SILVA (France) and Patricia M. GRIFFIN (United States of America)

This session is dedicated to the epidemiology and public health aspects of human salmonellosis. We would welcome studies of disease burden, outbreak investigations, risk factors for disease, and innovative surveillance and investigation methods. Communications about the role of molecular epidemiology (e.g. whole genome sequencing) in surveillance and outbreak detection/investigation are strongly encouraged. Additional suggested topics for communications include emergence, burden, outbreaks, trends, surveillance, study design, and molecular epidemiology.
