species, especially and , 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 and isolates. Recently, acquired linezolid-resistance mechanisms have been reported in spp.

- This study examines plasmid-mediated quinolone resistance (PMQR) in bacteria from chickens, their eggs, and poultry farm environments in northeastern Tunisia, analyzing 139 samples.
- Researchers found high resistance rates against various antibiotics, including a 100% resistance to erythromycin and tetracycline, with all quinolone-resistant strains carrying a specific mutation in the GyrA protein.
- Additionally, the study identified a new sequence type (ST13450) among eleven isolates and highlights the novel presence of PMQR genes in Tunisia, marking a significant finding in the field.
Characteristics of infection in intensive care unit before (2007-2010) and after (2011-2014) the beginning of an antimicrobial stewardship program.

Objectives: To investigate the factors associated with isolates in intensive care unit (ICU) before and after an antimicrobial stewardship program.
Materials: Monocentric retrospective cohort study. Patients admitted to the ICU in 2007-2014 were included.
The gene is the most widespread gene encoding aminoglycoside-modifying enzyme and conferring resistance to tobramycin, streptomycin and kanamycin. The variant gene confers resistance to both aminoglycosides and fluoroquinolones (FQ). A total of 132 isolates, including 91 and 41 , were selected from broiler hens isolates.
