Induction of Acinetobacter baumannii natural competence

Bacteria acquire and spread genetic information through several means. Some bacteria form a long, thin tube called a pilus, mediating transfer of DNA by direct cell-to-cell contact, in a process known as conjugation. Some bacterial take up environmental DNA and incorporate it into their existing... Read More
