General Veterinary Microbiology: Flagella

Flagella

FLAGELLA

Flagella are hair like helical appendages that protrude through the cell wall. They are responsible for bacterial motility. The diameter of the flagellum is 0.01-.0.02 um. It is thinner than the flagella or cilia of eukaryotes. Location of the flagella varies depending on the species.

Monotrichous: Single polar flagellum. Eg: Pseudomonas aeruginosa
Lophotrichous: A cluster of polar flagella. Eg: Pseudomonas fluorescens
Amphitrichous: Single or clusters of flagella at both cell poles. Eg: Aquaspirillum serpens
Peritrichous: Surrounded by lateral flagella. Eg: Salmonella typhi
Atrichous: No flagella
