In this study, a total of four L. monocytogens STs (ST5, ST121, ST120, and ST2) have been identified in two RTE food plants from 2019 to 2020 in Shanghai, China. The L. monocytogenes ST5 was predominant in one RTE food processing plant, and ...A. First remember that Listeria is a facultative intracellular microbe, so it can exist inside and outside host cells. Inside host cells it uses actin to polymerize and jut itself forward (like the actin-rockets in Santa's bag and on the floor), while outside cells it uses flagella to tumble (like the ornaments tumbling off the tree). 4. Q.Listeriosis (Listeria infection) Reviewed: March 2023 . What is listeriosis? Listeriosis is an infection caused by the bacteria Listeria monocytogenes. People become infected by eating foods contaminated with the bacteria.
