What are symptoms of spirochetes?
Spirochaetes are organisms that can infect the colon of people with normal or compromised immune systems. Infected patients can present with a variety of gastrointestinal symptoms, including diarrhoea and rectal bleeding.
Are spirochetes bad?
Spirochetes cause several diseases in man and animals, including syphilis, Lyme disease, stomach ulcers, cat scratch fever, trench mouth, pyorrhea, and necrotizing ulcerative gingivitis. This list is by no means exhaustive, as there are several diseases caused by these bugs.
Are spirochetes contagious?
There can be lesions on the genitals that look like genital warts, but are caused by spirochetes rather than the wart virus. These wart-like lesions, as well as the skin rash, are highly contagious. The rash can occur on the palms of the hands, and the infection can be transmitted by casual contact.
Where are spirochetes found?
Spirochetes are a group of six genera of spiral-shaped, slender bacteria of varying length. They are either free-living or host-associated. They are found in the human oral cavity, gastrointestinal tracts of humans, mammals, insects, and in marine environments.
What human diseases are caused by spirochetes?
Of mammalian pathogens, some of the most invasive come from a group of bacteria known as the spirochetes, which cause diseases such as syphilis, Lyme disease, relapsing fever and leptospirosis. Most of the spirochetes are characterized by their distinct shapes and unique motility.
Where can I find a picture of a spirochete?
Visit the Microbe Zoo for pictures and information about spirochetes and other bacteria which live in the cow rumen. For more technical information try the Intestinal Spirochete Homepage, the Spirochete List Server, or the Borrelia and Treponema Molecular Genetics servers.
Where do spirochetes embed themselves in the colon?
Pathophysiology Electron microscopic studies reveal that generally spirochetes embed themselves in the luminal border of colonocytes without invasion The mechanism of diarrhea in noninvasive cases is believed to be related to loss of absorptive surface from loss of microvilli Invasive cases are uncommon and the mechanisms of invasion are unclear
Can a dog with diarrhea have a spirochete?
In dogs with diarrhea, spirochetes can appear in the feces in large numbers. Whether the spirochetes are causal to the diarrhea or alternatively, mechanically dislodged from the crypts by diarrhea induced by other etiologic factors, remains an area of active debate. In a small number of cases]
What do spirochetes look like in a cow?
Both syphilis and Lyme disease are caused by these bacteria, and other species are important symbionts in the stomachs of cows and other ruminants. Spirochetes are long and slender bacteria, usually only a fraction of a micron in diameter but 5 to 250 microns long. They are tightly coiled, and so look like miniature springs or telephone cords.

How is Spirochetosis of the small intestine treated?
Symptomatic patients are generally treated with metronidazole, although symptoms may resolve without treatment A basophilic, fringe-like, end on end attachment of filamentous densely packed spirochetes on the surface epithelium of the large intestine or appendix generally in an otherwise normal study
How is the diagnosis of colonic spirochaetosis made?
It is therefore unclear whether the spirochaetes colonising the colon are true pathogens. Diagnosis is typically made by histological examination, with the biopsy specimen showing a band‐like growth of spirochaetes adherent to the colonic luminal surface, giving an accentuated brush‐border appearance.
Can a PCR detect nontreponemal spirochetes in stool?
Biopsy or resection showing the presence of the nontreponemal spirochetes Brachyspira aalborgi or Brachyspira pilosicoli on the surface epithelium of the large intestine or appendix PCR or culture may detect B. aalborgi or B. pilosicoli in stool, but the significance is unclear
