Abstract

Counts of acid-fast bacilli were made on homogenates of whole liver, whole spleen, and two femurs of CBA mice killed at various time intervals after intravenous infection with Mycobacterium lepraemurium. The growth curves so obtained showed that the bacillus multiplied faster in bone marrow than in liver or spleen. No evidence of redistribution during the early part of infection was obtained. The time of appearance of significant numbers of bacilli (10(7)) in the bone marrow was used to make estimates of viability of M. lepraemurium suspensions. Several applications of the techniques described are discussed.

摘要

对静脉注射感染鼠麻风杆菌后在不同时间间隔处死的CBA小鼠的全肝、全脾和两根股骨匀浆进行抗酸杆菌计数。由此获得的生长曲线表明,该杆菌在骨髓中的繁殖速度比在肝脏或脾脏中更快。在感染早期未发现重新分布的证据。利用骨髓中出现大量杆菌(10⁷)的时间来估计鼠麻风杆菌悬液的活力。讨论了所述技术的几种应用。
