Its worldwide spread, outside the original endemic foci of Southeast Asia and Australia, is favoured by global warming and the diabetes mellitus pandemic, which is the main predisposing factor.In humans, melioidosis is an opportunistic infection, following professional (rice farmers, soldiers) or accidental contamination, by inhalation or inoculation. B. pseudomallei is a facultative intracellular bacterium that can overcome host immune defences, induce acute, subacute, or chronic invasive infection, or remain latent for years. The acute infection is polymorphic, bacteraemic in more than 50% of cases, frequently complicated by shock, and revealed by visceral abscesses, most often pulmonary. It is fatal in 20 to 50% of cases, the prognosis depending on the delay before the establishment of effective first-line antibiotic therapy, using ceftazidime or carbapenems, and therefore on the speed of bacteriological diagnosis.B. pseudomallei is a saprophytic bacterium, resident of the rhizosphere where it has developed and accumulated capacities to overcome environmental stresses and competition with organisms living in such ecosystem.

The sources of bacteria or antimicrobial resistance genes are linked to human activities: urban, hospital and industrial discharges, livestock farms). The role of sanitation systems-sewerage, wastewater treatment and sludge treatment (WWTP)-in the problem of AMR has not yet been clearly established by the scientific community. The data available to date show that they eliminate part of the bacteria, genes and antibiotics, although this is not their primary vocation. WWTPs thus play an important filtering role to limit dissemination in the environment. On the other hand, some authors warn against their potential involvement in the selection of new resistant germs, given the conditions conducive to the exchange of genetic material between microbial strains of various types and exposed to selective agents. Today, knowledge of the mechanisms involved in the selection of antibiotic resistance and the fate of bacteria and resistance genes within sanitation systems remains limited.

Vincent Mouly joined this laboratory for his PhD in 1982, and defined the different populations of myoblasts appearing during development in birds and then in humans. Together, they demonstrated the impact of the limit in proliferation of the precursor cells on the regenerative capacity of human skeletal muscle, and their group developed models to evaluate the regenerative potential of skeletal muscle in vitro, measuring the telomeric erosion, and identified the involvement of a stress pathway in the proliferative arrest of muscle progenitors. A platform to produce human immortalized muscle cell lines was the successful result of this research, initiated with François Gros and W. E. Wright. The in vivo regenerative potential of human muscle cells was evaluated by injection into muscles of immunodeficient mice. Their group in collaboration with the clinical team of Professor Jean Lacau St-Guily and Professor Sophie Perié completed a successful autologous myoblast transplantation clinical trial for Oculo-pharyngeal muscular dystrophy.
