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

Characterization of a Multiresistance Plasmid Carrying the optrA and cfr Resistance Genes From an Enterococcus faecium Clinical Isolate [PDF]
Frontiers in Microbiology, 2018 Enterococcus faecium E35048, a bloodstream isolate from Italy, was the first strain where the oxazolidinone resistance gene optrA was detected outside China. The strain was also positive for the oxazolidinone resistance gene cfr.

Identification of the Phenicol Efflux Gene fexB and Its Co‐Occurrence With the Oxazolidinone/Phenicol Resistance Gene optrA in Avian Campylobacter jejuni Isolates From Tunisia [PDF]
International Journal of Microbiology, Volume 2026, Issue 1, 2026.Background Campylobacter jejuni, a major foodborne and zoonotic pathogen linked to poultry, is showing rising resistance to last‐resort antimicrobials like oxazolidinones and phenicols. Such resistance threatens both animal and human health. Its ability to acquire genes from gram‐positive bacteria highlights the need for surveillance in avian ...
