2. FLAGELLA :
• Flagella are hair like structure that protrude through the cell wall
and are usually exceeding the length of bacteria
• Filament is made up of protein namely FLAGELLIN
• Swimming is one of the locomotion of bacteria in liquid movement which
is aided by flagella

3. CLASSIFICATION OF BACTERIA BASED
ON FLAGELLA
Atrichous
Monotrichous
Cephalotrichous
Amphitrichous
Peritrichous
Lophotrichous

4. • ATRICHOUS :
Bacteria without flagella
EXAMPLE : Xylella
• MONOTRICHOUS :
Bacteria with single flagella at one end.
EXAMPLE : Xanthomonas sp
• CEPHALOTRICHOUS :
Bacteria with several flagella at one end.
EXAMPLE: Pseudomonas fluorescens
• AMPHITRICHOUS :
Bacteria with one flagella at both end.
EXAMPLE : Pseudomonas sp

5. • PERITRICHOUS :
Bacteria with flagella all over its body .
EXAMPLE: Erwinia sp
• LOPHOTRICHOUS :
Two or more flagella at both the poles of the bacterium
EXAMPLE : Spirillum types of bacteria
