Comparative genomics unveils extensive genomic variation between populations of Listeria species in natural and food-associated environments

Jingqiu Liao,
Xiaodong Guo,
Shaoting Li
et al.

Abstract: Comprehending bacterial genomic variation linked to distinct environments can yield novel insights into mechanisms underlying differential adaptation and transmission of microbes across environments. Gaining such insights is particularly crucial for pathogens as it benefits public health surveillance. However, the understanding of bacterial genomic variation is limited by a scarcity of investigations in genomic variation coupled with different ecological contexts. To address this limitation, we focused on List… Show more

“…Although some CCs are present globally and are very similar at the core-genome level, their accessory genome can vary from region to region [ 24 ]. Within these variations in the accessory, some genetic elements may affect virulence.…”

“…The primary reason for this phenomenon may be attributed to the different environments in which the strains reside. Hence, in order to adapt to these unique environments, the strains have evolved genes that are specific to these environments to counteract environmental pressures ( Liao et al, 2023 ). This is also very intriguing, as it allows for the exploration of the differences among L. monocytogenes strains in different regions, analyzing the unique characteristics of strains in different areas, thereby studying the evolutionary patterns of strains in that region, and subsequently devising targeted prevention and control measures for that region.…”
