If flagella are absent, how do theses bacteria move through mammallian tissue?
Bacteria can hitch a ride in the blood stream or lymphatic system, this is called transmigration.


They can live on the surface of your skin and be ingested when you put your fingers in your mouth, which is how your gut is colonized with E. coli when you are a neonate. You can contaminate your other mucous membranes with bacteria, like those lining your mouth, genital region (glans for men, vagina for women), and the like. Bacteria can also be inhaled and transmigrate through the tissues lining your lungs.


Those bacteria that are not scavenged by macrophages, and other immune cells soon set up shop where the environment is cosy, usually on the skin, in mucous membranes (which include the gut) or in the blood stream .
