 From feces. An unstable variant closely 

 related to Escherichia coli characterized 

 by irregular lactose fermentation. When 

 cultured on lactose indicator agar, it 

 appears not to ferment lactose. After 

 some days, lactose-fermenting papillae 

 appear growing on or out of the original 

 colonies. Subcultures from these sec- 

 ondary colonies give typical lactose 

 fermentation but subculture from the 

 primary colony, avoiding contact with the 

 papillae, gives delayed fermentation of 

 lactose and when again plated will pro- 

 duce non-fermenting colonies on which 

 fermenting papillae later appear.
