What are Spirochaetes And how do you classify them?
The spirochetes are presently classified in the Class Spirochaetes in the order Spirochetales and are divided into three major phylogenetic groupings, or families. The first family Spirochaetaceae contains species of the genera Borrelia, Brevinema, Cristispira, Spirochaeta, Spironema, and Treponema.
What Kingdom is a spirochetes in?
Spirochetes are classified as bacteria in the order Spirochaetales and contain two families—the Spirochaetaceae and the Leptospiraceae. The Spirochaetaceae family includes four genera: Spirochaeta, Cristispira, Treponema, and Borrelia.

Which microorganism is a spirochaete?
spirochete, (order Spirochaetales), also spelled spirochaete, any of 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.
What are the characteristics of Spirochaetes?
Spirochetes are gram-negative, motile, spiral bacteria, from 3 to 500 m (1 m = 0.001 mm) long. Spirochetes are unique in that they have endocellular flagella (axial fibrils, or axial filaments), which number between 2 and more than 100 per organism, depending upon the species.
Is Lyme disease recognized in Canada?
Lyme disease is emerging in Canada due to expansion of the range of the tick vector Ixodes scapularis from the United States. National surveillance for human Lyme disease cases began in Canada in 2009. Reported numbers of cases increased from 144 cases in 2009 to 2025 in 2017.
Can you get Lyme disease in the UK?
Lyme disease can be contracted anywhere in the UK but is more common in the south of England and the Scottish Highlands. Only a small minority of ticks in the UK are infected with the bacteria that cause Lyme disease.
Is Borrelia burgdorferi prokaryotic or eukaryotic?
classified in the prokaryotic kingdom Monera.
Are the spirochaetes present in the mouth pathogenic?
Reaction between infected periodontal tissue and monoclonal antibodies to Treponema pallidum has suggested that uncharacterized pathogen-related oral spirochaetes have surface structures and functions analogue to this well recognized pathogen.
