摘要: Pasteurella multocida causes fowl cholera, a highly contagious and severe disease in chickens water fowls. The is not well described less intensive production systems, including scavenging family poultry developing countries. P. was isolated from 25.9% of healthy-looking ducks 6.2% free-range farms at slaughter slabs market. On experimental infection with 1.2 to 2.0×108 organisms the type strain (NCTC 10322T), 12-week-old expressed cholera clinical signs significantly more times (372 signs) than those 4-week-old, 8-week-old 16-week-old (173, 272 187 were severe. In birds (188 other age groups (117, 80, 83 signs, respectively) frequent. transmitted seeder (n=12) sentinel (n=30), which develo...
