lysogeny defined in 1951 yearlysogeny - lysogeny;
lysogeny - Relationship between bacteriophage of a non-virulent (temperate) kind and bacterium. The temperate bacteriophage does not multiply after entering bacterial cell, nor cause lysis, but instead its genetic material, DNA, becomes attached to that of the bacterium and is reproduced with it at each division of the bacterial cell. This attached condition, the prophage state, may continue through many generations of the bacterial cells. Bacteria carrying prophage are said to be lysogenic; with rare exceptions their other characteristics are unaltered. Spontaneous change to production of complete bacteriophage particles, with lysis of the bacterial cell, occurs occasionally in a lysogenic cell, and can be induced (prophage induction) by treatments that induce mutations in other organisms. Prophage, and other kinds of genetic elements having similar relationship with bacteria are termed episomes.
