李斯特菌属目前由17种组成，其中包括自2009年以来新描述的9种李斯特菌。基因组和表型数据清楚地定义了一组独特的六个物种（狭义李斯特菌），这些物种具有共同的表型特征（例如，在低温下生长的能力，鞭毛运动性）;这组包括病原体单核细胞增生李斯特菌。其他11种（广义李斯特菌）代表三个不同的单系群，这可能需要承认为单独的属。这三个拟议的属不含病原体，是非运动的（除了格雷李斯特菌），能够减少硝酸盐（除了佛罗里达李斯特菌），并为阴性的Voges-Proskauer测试（除了L。grayi）。与所有其他李斯特菌物种不同，拟议中的新属Mesolisteria的物种不能在7 °C以下生长。虽然大多数新的李斯特菌物种仅在少数国家被鉴定，但用于快速表征推定李斯特菌分离株的分子工具的可用性可能会导致未来鉴定代表这些新物种的分离株。广义李斯特菌分离株的鉴定不仅可以更好地理解李斯特菌的进化和李斯特菌的毒力特征，而且还具有实际意义，因为李斯特菌物种的检测通常被食品工业用作检测允许李斯特菌存在、生长和持续存在的条件的标志物。单核细胞增多症这篇综述将提供一个全面的关键总结，我们目前的理解的特点和分布的新李斯特菌物种的重点是广义李斯特菌。
The genus Listeria is currently comprised of 17 species, including 9 Listeria species newly described since 2009. Genomic and phenotypic data clearly define a distinct group of six species (Listeria sensu strictu) that share common phenotypic characteristics (e.g., ability to grow at low temperature, flagellar motility); this group includes the pathogen Listeria monocytogenes. The other 11 species (Listeria sensu lato) represent three distinct monophyletic groups, which may warrant recognition as separate genera. These three proposed genera do not contain pathogens, are non-motile (except for Listeria grayi), are able to reduce nitrate (except for Listeria floridensis), and are negative for the Voges-Proskauer test (except for L. grayi). Unlike all other Listeria species, species in the proposed new genus Mesolisteria are not able to grow below 7 °C. While most new Listeria species have only been identified in a few countries, the availability of molecular tools for rapid characterization of putative Listeria isolates will likely lead to future identification of isolates representing these new species from different sources. Identification of Listeria sensu lato isolates has not only allowed for a better understanding of the evolution of Listeria and virulence characteristics in Listeria but also has practical implications as detection of Listeria species is often used by the food industry as a marker to detect conditions that allow for presence, growth, and persistence of L. monocytogenes. This review will provide a comprehensive critical summary of our current understanding of the characteristics and distribution of the new Listeria species with a focus on Listeria sensu lato.
