Gallibacterium anatis as an emerging pathogen in pet birds: biofilm formation contributes to treatment challenges and persistence

These results support the idea that G. anatis is a potentially important pathogen, with a biofilm-forming ability that contributes to treatment failure and environmental persistence. The 45% prevalence of multidrug resistance (MDR) highlights the pressing need for antimicrobial stewardship in avian veterinary medicine. Given the zoonotic potential of G. anatis, our study underscores the importance of One Health surveillance efforts in mitigating risk to both poultry and humans.
