描述(由申请人提供):活动性肺结核引起肺腔,在肺腔中结核细菌生长到高水平。空腔结核更容易传染给他人,患者更难治疗,而且更有可能导致耐药性。该提案将把结核腔可重复发展的动物模型与新的放射成像技术和传统药理学工具结合起来,以确定结核腔是否可以作为细菌逃离高浓度药物并产生耐药性的避难所。该研究的最后一部分将确定,在结核病动物模型中,将免疫抑制药物与抗生素联合使用是否有助于加速结核病的治愈。
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.
