Information – How Do You Know if You Have a Listeria monocytogenes Infection?

Food Poisoning Bulletin

Listeria monocytogenes is a foodborne pathogen that can make you seriously ill. Listeria monocytogenes infections are tricky, because the symptoms may not show up until 70 days after a person has been exposed. And the symptoms of this infection are similar to the flu, especially in pregnant women, so diagnosis can be difficult. Full article at the link above.

Research – Listeria Species – 20 Members! Welcome – Listeria thailandensis

IJS Microbiology Research

During a screening of Listeria species in food samples in Thailand, a Listeria -like bacterium was recovered from fried chicken and could not be assigned to any known species. Phylogenetic analysis based on the 16S rRNA gene and on 243 Listeria core genes placed the novel taxon within the Listeria aquatica Listeria floridensis Listeria fleishmannii and Listeria costaricensisclade ( Listeria sensu lato), with highest similarity to L. floridensis (98.9 %) and L. costaricensis (98.8 %). Whole-genome sequence analyses based on the average nucleotide blast identity (ANI<86 %), the pairwise amino acid identity (AAI>64 %) and on the percentage of conserved proteins (POCP>77 %) with currently known Listeria species confirmed that the strain constituted a new taxon within the genus Listeria . At the phenotypical level, it differs from other Listeria species by the production of acid from d-tagatose and inositol. The name Listeria thailandensis sp. nov. is proposed for the novel species, and is represented by the type strain CLIP 2015/00305 (=CIP 111635=DSM 107638).
