There are two families, ''[[:Category:Leptospiraceae|Leptospiraceae]]'' and ''[[:Category:Spirochaetaceae|Spirochaetaceae]]''.
There are two families, ''[[:Category:Leptospiraceae|Leptospiraceae]]'' and ''[[:Category:Spirochaetaceae|Spirochaetaceae]]''.
''Leptospiraceae'' include the pathogens of the genus, ''Leptospira'', whereas ''Spirochaetaceae'' include the pathogens of the genera ''[[Borrelia]]'' and ''[[Brachyspira hyodysenteriae|Brachyspira]]''. Spirochaetes may cause zoonotic infections.

==Characteristics==
==Characteristics==
''Spirochaetes'' are spiral or helical Gram-negative bacteria. They are motile organisms as they have endoflagella. The position of their flagella is used to distinguish this bacteria, they run length ways and cause a twisting motion. They have lengths between 5 and 250 µm. They are sensitive to dessication and survive poorly in the environment.

==Diagnosis==
They stain poorly with Gram stain as most require specialised media for growth. Serology is required for their identification.
