Peritrichous
flagella all over (peri- perimeter)
Peritrichous refers to the arrangement of flagella on a bacterial cell that are distributed all over its surface. Peri means “all around” and trichous means “hairy.” Therefore, peritrichous bacteria have flagella that are distributed all over the surface of the cell, giving it a hairy appearance. These flagella are used for bacterial motility, allowing the bacteria to move towards favourable environments or away from unfavourable ones.
Peritrichous arrangement of flagella is quite common among bacterial species, and it is believed to provide better motility in liquid environments. These bacteria can swim in any direction, and their movement often resembles a tumbling motion. Despite their ability to move, peritrichous bacteria can also attach to surfaces, forming biofilms. Different bacteria have varying numbers and lengths of flagella, which can affect their swimming speed and behaviour.
Overall, the peritrichous arrangement of flagella is an important characteristic of many bacterial species, allowing them to move and colonize diverse environments.
