Role of Pasteurella surface polysaccharides in pathogenesis and immunity

牲畜感染在全世界造成重大经济损失。多杀性巴氏杆菌会导致多种牲畜疾病，包括牛的出血性败血症和家禽的禽霍乱。多杀性巴氏杆菌的两种表面多糖结构，荚膜和脂多糖，是多杀性巴氏杆菌致病的关键。我们的数据表明，改变这些结构的量/含量也会影响疫苗性能。该项目旨在确定这些多杀性巴氏杆菌结构的产生是如何控制的，以及这些结构的变化是否会影响其感染不同动物/鸟类的能力。利用这些信息，该项目旨在开发具有上级疾病覆盖率的最先进的牲畜疫苗。

Livestock infections cause major economic losses worldwide. The bacterium Pasteurella multocida causes multiple diseases in a range of livestock, including hemorrhagic septicaemia in cattle and fowl cholera in poultry. Two surface polysaccharide structures, capsule and lipopolysaccharide, are crucial for P. multocida to cause disease. Our data indicate that varying the amount/content of these structures also affects vaccine performance. This project aims to identify how the production of these P. multocida structures are controlled and if changes to these structures affect its ability to infect different animals/birds. Using this information, the project aims to develop state-of-the-art livestock vaccines with superior disease coverage.
