Poultry erysipelas – a case series from 1998–2023, highlighting diagnostic features, farmer interventions and molecular epidemiology

Key Points

• To explore the diagnostic features, interventions by farmers, and molecular epidemiology associated with poultry erysipelas outbreaks.
• Analyzed a series of cases from 1998 to 2023
• Examined diagnostic features of erysipelas
• Evaluated farmer interventions during outbreaks
• Utilized pre-enrichment and selective culture techniques
• Most outbreaks were found in organic and free-range laying hen flocks
• Co-infections were common, necessitating selective culture
• Isolates were often clonal, indicating similar sources of infection
