Enteric Bacterial Pathogens

The classical biotype of Vibrio cholerae O1 was responsible for the first six cholera pandemics, but is relatively unknown, with only 20 genome sequences (50% of which come from the same geographic area) for […]

Cholera is thought by many to be a disease of the Victorian era. However, Yemen has recently experienced one of the largest ever cholera epidemics. The first cases were declared in September 2016, and […]

Little is known about the emergence and spread of the first antibiotic-resistant populations. It is believed, for example, that the very common penicillinase gene, blaTEM-1, discovered for the first time in E. coli in Greece […]

This project intends to share expertise, developments, equipement and bioinformatics tools to apply Oxford Nanopore Technology sequencing to the detection, diagnostic and characterization of pathogens of public health importance. It corresponds to a collaboration […]

In 1970, ten years after the beginning of the 7th pandemic (Indonesia, 1961), cholera hit Africa, where it has remained entrenched. Three decades later, the reported incidence of indigenous cholera in sub-Saharan Africa was […]

The agent of epidemic dysentery, the bacterium Shigella dysenteriae type 1, was isolated in Japan in 1897 by Dr Kyoshi Shiga during a massive epidemic of bloody diarrhea that caused 20,000 deaths over a […]

The Unit includes two National Reference Centers (CNR) and a WHO Collaborating Center. Our interests are the population dynamics of bacterial enteric pathogens such Salmonella, Shigella/Escherichia coli and Vibrio, with a special focus on […]

CRISPR polymorphism is a powerful tool to subtype Salmonella strains and is now used in routine for epidemiological investigations. This tool gets a CRISPR profile by identifying the presence of known spacers and direct […]
