Flagellate bacteria
WebMany bacteria swim in liquid or swarm over solid surfaces by synthesizing rotary flagella. The same bacteria that are motile also commonly form nonmotile multicellular aggregates called biofilms. Biofilms are an important part of the lifestyle of pathogenic bacteria, and it is assumed that there is a motility-to-biofilm transition wherein the ...

WebMar 2, 2024 · Comma-shaped bacteria – Vibrio. Vibrio are curved bacteria that appear like a comma with 1 – 3 whip-like structures at one end. Helical or spiral bacteria – Spirilla. Spirillas have a spiral or helical shape with whip-like flagella at one end. They are divided into two subtypes based on thickness, flexibility and motility of the cell. The three types of flagella are bacterial, archaeal, and eukaryotic. The flagella in eukaryotes have dynein and microtubules that move with a bending mechanism. Bacteria and archaea do not have dynein or microtubules in their flagella, and they move using a rotary mechanism. Other differences among these three types are:
