描述(申请人提供):活动性肺结核导致肺结核细菌生长到高水平的肺洞。空洞型结核病更容易传播给其他人,患者更难治疗,而且更有可能导致耐药性。这项提议将结合结核空洞可重复发展的动物模型,利用新的放射成像技术和传统药理学工具来确定结核空洞是否作为细菌可能逃脱高浓度药物并产生耐药性的避难所。这项研究的最后部分将确定给予免疫抑制药物和抗生素一起阻止空洞发展是否有助于加速结核病动物模型的治愈。
英文摘要
DESCRIPTION (provided by applicant): Active tuberculosis causes lung cavities where TB-bacteria grow to high levels. Cavitary TB is more transmissible to others, harder to treat in the patient who has it, and more likely to lead to drug resistance. This proposal will combine an animal model in which TB cavities reproducibly develop with novel radiologic imaging technologies and traditional pharmacologic tools to determine whether the TB cavity serves as a sanctuary site where bacteria may escape high drug concentrations and develop resistance. The last part of the study will determine whether giving immunosuppressive drugs which block cavity development together with antibiotics is useful in accelerating cure in an animal model of TB.
