Abstract
Molecular manipulation has been a limiting factor in C. jejuni research for many years. Recent advances in molecular techniques adapted for C. jejuni have furthered our understanding of the organism. This unit is dedicated to common molecular tools in bacterial research specifically tailored for C. jejuni. These include colony PCR, DNA isolation, and RNA isolation. The unit also reviews techniques for genetic manipulation, such as the use of plasmids, natural transformation, electroporation, conjugation, and transposition. In addition, a reporter system, the arylsulfatase assay, can be used to study gene expression.
