Emmy Klieneberger-Nobel discovered L-forms while researching this genus, sparking debate about if a shared fried-egg appearance indicated a shared nature. Members of this genus are characteristically pleomorphic in cultures because they incorporate cholesterol directly from media. This genus (10[1])is introduced to cell lines by human breath, necessitating monthly screening. (10[1])Leonard Hayflick developed a culture for this genus after working with animal pleuropneumoniae. A DNA watermark linking to the J. Craig Venter Institute was the culmination of work begun in this genus’s genitalium species. (10[1])Species of Chlamydia and this genus are the main (-5[1])causes of atypical (10[1])pneumonia. The first synthetic organism (-5[1])was derived from members of this (10[1])genus with minimal (10[1])genomes. For 10 points, name this genus of very small bacteria that lack cell walls.
