Comparative studies were carried out to investigate the proliferations of avian type tuberclebacilli and nonphotochromogens in developing eggs.<BR>A volume of 0.2ml of mycobacterial cell suspension of 2 mg/ml was inoculated into yolk sacof 5 day old developing egg. After an appropriate time of incubation proliferations of mycobacteria were estimated by counting microscopically and by culturing. The experimentsshowed avian type tubercle bacilli grew more rapidly than nonphotochromogens. These twogroups of mycobacteria influenced differently on the hatching of the developing eggs afterintra-yolk sac inoculation, i. e., the eggs inoculated with nonphotochromogens hatched completely, while a quarter to a half of the eggs inoculated with avian type tubercle bacilli did not hatch.<BR>Several strains of "unclassified mycobacteria" not yet classified were examined by this experimental method and their growth characteristics in yolk of developing eggs were discussed.
