Capteurs QEPAS pour la surveillance de la qualité de l'air

, 2020
Human activities, at a personal and at an industrial level, cause the release of numerous molecular species in the atmosphere. Even a very low level of certain molecules can lead to the alteration of the air quality.

Rare Taxa Are Key Links in Regional Antimicrobial Resistance Profiles in Dusts Across Diverse North American Regions

Environmental DNA, Volume 6, Issue 6, November–December 2024.
Environmental DNA from dust collected on vehicle cabin air filters was used to define regional antimicrobial resistance gene (ARG) profiles across Canada. Results indicated that qepA dominates resistance profiles across Canada and that ARGs showed positive relationships with human and livestock populations. Network analyses revealed a relatively stable

Occurrence of Florfenicol and Linezolid Resistance and Emergence of optrA Gene in Campylobacter coli Isolates from Tunisian Avian Farms

International Journal of Microbiology, Volume 2024, Issue 1, 2024.
Campylobacter species, especially C. coli and C. jejuni, have been associated with a range of human gastrointestinal diseases. During the last two decades, due to the irrational use of antibiotics in poultry farms, high rates of antimicrobial resistance have been globally reported in C. coli and C. jejuni isolates.
