Listeria monocytogenes is a gram positive bacterium and causes many food-borne infections such as Listeriosis.

[1] Tiling arrays and mutagenesis identified many non-coding RNAs within the L. monocytogenes genome and the location of these non-coding RNAs within the bacterial genome was confirmed by RACE (rapid amplification of cDNA ends) analysis.

An additional comparative study between the pathogenic L. monocytogenes strain and the non pathogenic L. innocua strain identified several non-coding RNAs that are only present within L. monocytogenes which suggests that these ncRNAs may have a role in pathogenesis.

[2] The tables below summarizes the location, flanking genes and also the characteristics of the novel small non-coding RNAs identified and the previously characterized non-coding RNAs present in L. monocytogenes aArrows indicate the sense of the gene on the genome.

Listeria monocytogenes EGD-e strain was used in these studies EMBL accession AL591824.1
