Remarks: |
The 16S-23S rRNA intergenic spacer (IGS) regions found in six Listeria species were characterized. PCR amplification of the 16S-23S IGS with a "generic primer" set generated products of about 340 bp (small) and 550 to 590 bp (large) with DNA from all Listeria strains tested. Seven Listeria monocytogenes serotype 4b strains and one L. monocytogenes serotype 4d strain also had an additional PCR product of ca. 360 bp. The 360-bp PCR product from one of these L. monocytogenes serotype 4b strains was identical in nucleotide sequence to the small 340-bp IGS, except that it contained an 18-bp tandem repeat. The small rRNA IGSs of L. innocua, L. ivanovii, L. seeligeri, L. welshimeri, and L. grayi were 83 to 99% homologous to that of L. monocytogenes. The large rRNA IGS of L. monocytogenes was 81 to 96% homologous to those of the other Listeria species and agreed with current taxonomic division among these species. The nucleotide sequences of the central 274 bp of the large rRNA IGS of strains from seven different L. monocytogenes serotypes were highly homologous; however, serotype-specific differences were noted, and four groups were identified within L. monocytogenes based on this analysis. |

Remarks: |
The phylogenetic interrelationships of members of the genus Listeria were investigated by using reverse transcriptase sequencing of 16S rRNA. The sequence data indicate that at the intrageneric level the genus Listeria consists of the following two closely related but distinct lines of descent: (i) the Listeria monocytogenes group of species (including Listeria innocua, Listeria ivanovii, Listeria seeligeri, and Listeria welshimeri) and (ii) the species Listeria grayi and Listeria murrayi. At the intergeneric level a specific phylogenetic relationship between the genera Listeria and Brochothrix was evident. The sequence data clearly demonstrated that the genus Listeria is phylogenetically remote from the genus Lactobacillus and should not be included in an extended family Lactobacillaceae. |

Remarks: |
A molecular method based on restriction fragment length polymorphism (RFLP) of PCR-amplified fragments of the 23S rRNA gene was designed to rapidly identify Listeria strains to the species level. Two fragments (S1, 460 bp, and S2, 890 bp) were amplified from boiled DNA. S2 was cut with the restriction enzymes XmnI or CfoI and, if needed, S1 was digested by either AluI or ClaI. This method was first optimized with six reference strains and then applied to 182 isolates collected from effluents of treatment plants. All isolates were also identified by the API Listeria kit, hemolysis, and phosphatidylinositol-specific phospholipase C production (PI-PLC) on ALOA medium. The PCR-RFLP method unambiguously identified 160 environmental strains, including 131 in concordance with the API system, and revealed that 22 isolates were mixed cultures of Listeria monocytogenes and Listeria innocua. Discrepant results were resolved by a multiplex PCR on the iap gene, which confirmed the PCR-RFLP data for 49 of the 51 discordances, including the 22 mixed cultures. Sequencing of the 16S rRNA gene for 12 selected strains and reconstruction of a phylogenetic tree validated the molecular methods, except for two unclassifiable strains. The 158 single identifiable isolates were 92 L. monocytogenes (including seven nonhemolytic and PI-PLC-negative strains), 61 L. innocua, 4 Listeria seeligeri, and 1 Listeria welshimeri strain. The PCR-RFLP method proposed here provides rapid, easy-to-use, inexpensive, and reliable identification of the six Listeria species. Moreover, it can detect mixtures of Listeria species and thus is particularly adapted to environmental and food microbiology. |

Remarks: |
We have recently cloned and characterized the inlC gene of Listeria monocytogenes which belongs to the listerial internalin multigene family and codes for a 30-kDa secreted protein containing five consecutive leucine-rich repeats. Here, we show that in L. monocytogenes inlC is located between the rplS gene (encoding the 50S ribosomal protein L19), and the infC gene (encoding the translation initiation factor 3). By direct and inverse polymerase chain reactions (PCR), we cloned a 5.4-kb region containing a homologous gene (termed i-inlC) from L. ivanovii, the other pathogenic member of the genus Listeria. In this microorganism, the i-inlC gene is preceded by another internalin gene, i-inlD, which seems to be specific for L. ivanovii, as this gene could not be detected in L. monocytogenes by Southern hybridization with an i-inlD gene probe. The i-inlD gene also encodes a small secretory internalin (i-InlD), which shares extended homology with (i-)InlC. Upstream of i-inlD are genes for 23S rRNA and 5S rRNA, and two tRNA genes [Asn-tDNA (GTT) and Thr-tDNA(GTT)]. The 3' terminus of the Thr-tRNA gene appears to be the site of an insertion of a genetic element including i-inlC and i-inlD. A putative transcriptional regulator gene, the product of which contains the TetR family signature, is located downstream of i-inlC. This chromosomal position of the two inlC genes on their respective chromosomes may be due to horizontal transfer of this gene. Transcription of i-inlC and i-inlD is strictly dependent on the transcriptional activator PrfA, which regulates transcription of most of the known virulence genes (including inlC) of L. monocytogenes and of L. ivanovii. |
