title: In vitro growth of Mycobacterium lepraemurium under the influence of macrophage cultures.
abstract: Elongation and limited multiplication of Mycobacterium lepraemurium was observed extracellularly when the bacilli spotted on a coverslip were placed face to face with cultures of mouse peritoneal macrophages adhering to the inside of a test tube held at an angle of 15 degree. There was no doubt that certain growth-promoting but unstable factors were released from the macrophages.
