“…The FC is a highly contagious bacterial disease of domestic and wild birds and is considered as a major threat to the poultry industries worldwide [6,7,67]. The disease is often associated with severe economic loss in the poultry industry due to high mortality and production loss.…”

“…The Gram-negative bacterium Pasteurella multocida is the etiologic agent of FC [4]. The disease magnitudes of FC can range from acute septicemia to chronic and localized infections with wattles, sinuses, legs, wing joints, and footpads often swollen and enlarged, and mortalities have been reported up to 20% [5,6]. The route of infection is oral or nasal with transmission through nasal exudate, faces, contaminated soil, equipment, and people [7].…”

“…Control of FC is primarily ensured by disinfection management and antibacterial therapy has been used extensively in the treatment of infected individuals [6]. However, the prolonged, indiscriminated, and unnecessary overuse of antibiotics in the poultry farms have resulted in an increased incidence of antimicrobial resistance (AMR) and multi-drug resistant (MDR) isolates of P. multocida, posing a serious threat to public health and livestock [8].…”

“…Though the outbreak of FC in Bangladesh is comparatively lower compared to other countries [6] and the number of isolates is few in number, this study was aimed to utilizing different bio-molecular techniques to investigate baseline information for the characteristic analysis of P. multocida. In addition, we have employed the state-of-the-art WGS technology to study the genotypic diversity and underlying genetic contents such as VFGs, AMR genes (ARGs), and metabolic functional potentials of two MDR and biofilm-forming isolates of P. multocida causing FC in laying hens in Bangladesh.…”

Background and Aim: Fowl cholera (FC) caused by Pasteurella multocida is a highly contagious bacterial disease of global importance for poultry production. The severity and incidence of FC caused by P. multocida may vary considerably depending on several factors associated with the host (including species and age of infected birds), the environment, and the bacterial strain. This study aimed to investigate the genetic diversity of multidrug-resistant P. multocida strains isolated from FC outbreaks in laying hens from commercial farms of Bangladesh. Materials and Methods: We collected 57 samples of suspected FC, including 36 live and 21 dead laying hens. P. multocida isolates were characterized by biochemical and molecular-biological methods. Results: Twenty-two strains of P. multocida were isolated from these samples through phenotypic and genotypic characterization. The strains were grouped into two distinct random amplification of polymorphic DNA (RAPD) biotypes harboring a range of pathogenic genes; exbB, ompH, ptfA, nanB, sodC, and hgbA. In this study, 90.90% and 81.82% P. multocida strains were multidrug-resistant and biofilm formers, respectively. Whole-genome sequencing of the two representative RAPD phylotypes confirmed as P. multocida type B: L2:ST122, harboring a number of virulence factors-associated genes (VFGs), and antimicrobial resistance (AMR) genes (ARGs). In addition, pan-genome analysis revealed 90 unique genes in the genomes of P. multocida predicted to be associated with versatile metabolic functions, pathogenicity, virulence, and AMR. Conclusion: This is first-ever report on the association of P. multocida genotype B: L2:ST122 and related VFGs and ARGs in the pathogenesis of FC in laying hens. This study also provides a genetic context for future researches on the evolutionary diversity of P. multocida strains and their host adaptation.

“…Although Bordetella avium is most commonly associated with bordetellosis in commercial turkeys (169,170), it is also frequently found in backyard and wild turkeys (171,172). Pasteurella multocida is a pathogen known for its acute nature and substantial mortality in both chickens and waterbirds (173,174) and has a seemingly global distribution in backyard chickens, having been reported from areas such as Upper Egypt (175), Ethiopia (176), Zimbabwe (112), Tanzania (177), Denmark (178), California (113), and India (179). The spillover and potential spillback of P. multocida ssp.…”

A Review of Pathogen Transmission at the Backyard Chicken–Wild Bird Interface

Habitat conversion and the expansion of domesticated, invasive species into native habitats are increasingly recognized as drivers of pathogen emergence at the agricultural-wildlife interface. Poultry agriculture is one of the largest subsets of this interface, and pathogen spillover events between backyard chickens and wild birds are becoming more commonly reported. Native wild bird species are under numerous anthropogenic pressures, but the risks of pathogen spillover from domestic chickens have been historically underappreciated as a threat to wild birds. Now that the backyard chicken industry is one of the fastest growing industries in the world, it is imperative that the principles of biosecurity, specifically bioexclusion and biocontainment, are legislated and implemented. We reviewed the literature on spillover events of pathogens historically associated with poultry into wild birds. We also reviewed the reasons for biosecurity failures in backyard flocks that lead to those spillover events and provide recommendations for current and future backyard flock owners.
