- Study reports first MDR B. cereus in wild birds in Egypt, isolated from 10.3% of 78 birds.
- Isolates showed β-hemolysis, lecithinase activity, and resistance to ampicillin, amoxicillin, doxycycline; susceptible to ciprofloxacin.
- High MAR indices (0.6-0.8) indicated exposure to high-risk contamination sources.
- Virulence genes hbl and pc-plc present in 100% of isolates; nhe and cytK in 50% and 37.5%.
- Antibiotic resistance genes bla1 and tetA in 100% of isolates; ermA in 75%.
- Wild birds may serve as carriers of toxigenic, antimicrobial-resistant B. cereus strains.
