Question

Spirochaete bacteria are exceptional in showing fast locomotion through thick mucus because of the presence of

• A. Flagellin in flagellum
• B. Acidic proteins in flagellum
• C. Additional bundles of elastic fibres
• D. None of the above

Answer 1

The correct option is C Additional bundles of elastic fibres

• Spirochete, (order Spirochaetales), also spelled spirochaete, are a group of spiral-shaped bacteria, some of which are serious pathogens for humans, causing diseases such as syphilis, yaws, Lyme disease, and relapsing fever. Examples of genera of spirochetes include Spirochaeta, Treponema, Borrelia, and Leptospira.
• Spirochaete bacteria are exceptional in showing fast locomotion through thick mucus because of the presence of additional bundles of elastic fibres.
  
• So, the correct answer is 'Additional bundles of elastic fibres'.
