WebBacterial flagella refer to the locomotory apparatuses, which help the bacteria to swim in the liquid nutrient medium. The bacteria possessing flagella are the motile organisms or flagellates. Conversely, the non-motile organisms or non-flagellates lack flagella. WebFeb 1, 2024 · Flagella are usually found in gram-negative bacilli. Gram-positive rods (e.g., Listeria species) and cocci (some Enterococcus species, Vagococcus species) also have flagella.
