Horizontal Gene Transfer and Loss of Serotype-Specific Genes in Listeria monocytogenes Can Lead to Incorrect Serotype Designations with a Commonly-Employed Molecular Serotyping Scheme

Brown, P., Kucerova, Z., Gorski, L., Chen, Y., Ivanova, M., Leekitcharoenphon, P., … Kathariou, S. (2022, December 6). (K. Chousalkar, Ed.). MICROBIOLOGY SPECTRUM, Vol. 12.

author keywords: Listeria monocytogenes; PCR; serotype; foodborne pathogens; horizontal gene transfer
MeSH headings : Pregnancy; Female; Humans; Aged; Listeria monocytogenes / genetics; Serogroup; Serotyping; Gene Transfer, Horizontal; Listeriosis
TL;DR: Serotyping remains extensively employed in Listeria epidemiologic investigations, and a multiplex PCR-based serotyping scheme is widely used, however, the PCR gene targets can be lost or gained via horizontal gene transfer, leading to novel PCR profiles without known serotype designations or to incorrect serotype assignments.
