A bacterium infected with a non-replicative bacteriophage (prophage). This infection is called lysogenization. The DNA of the prophage is integrated into the bacterial chromosome and replicates as the bacterium divides. When the prophage repressor is inactivated by artificial manipulation such as UV irradiation or chemicals, phage proliferation is induced. The phenomenon of transduction is observed using lysogens.

非増殖性のバクテリオファージ(プロファージ)の感染を受けた細菌。感染を受けることを溶原化という。プロファージのDNAは細菌の染色体に組み込まれていて,細菌の分裂とともに複製される。紫外線照射や化学物質などの人為的操作でプロファージのリプレッサーが非活性化されるとファージの増殖が誘発される。形質導入の現象は,溶原菌を用いて観察される。
