Hydrogensulphide producing variants of Escherichia coli.

摘要: In Denmark 26 isolates of hydrogensulphide producing Escherichia coli were found during a period 14 months beginning in May 1969. The occurred 25 different patients nine hospitals three geographical areas and they belonged to 13 serotypes 11 fermentation types. It is therefore concluded that do not belong one but many clones E. coli. Experimentally it shown the H2S capacity from possessed by ordinary Also has been demonstrated variants can transfer its for production an under circumstances pointing towards episome as most plausible mechanism. idea themselves originated immediately suggests itself, there are at present sufficient data substantiate idea.
