  Summary of report: Control of Intestinal Spirochaete Infections in Chickens
Studies in Europe and the United States have found that infection of the caeca with intestinal spirochaetes is associated with the occurrence of wet droppings, delayed onset of egg laying, faecal staining of eggshells, reduced egg weights and reduced carotenoid content of eggs.
There were some spirochaete species differences in their susceptibility to the drugs, but in general there was a high degree of susceptibility of the isolates to most of the drugs.
In general the spirochaete species remain susceptible to a range of antimicrobial agents, although resistance against tylosin was evident for a number of strains.

  Spirochaete   (Site not responding. Last check: 2007-11-06)
The spirochaetes are a phylum of distinctive bacteria, which have long, helically coiled cells.
It has been suggested by Lynn Margulis that eukaryotic flagella were derived from symbiotic spirochaetes, but few biologists accept this, as there is no close structural similarity between the two.
The spirochaetes are divided into three families, all placed within a single order.

 New spirochaete isolated from sheep
The organism was isolated by the investigators from a fluid sample taken from a sheep severely affected with foot rot.
This member of the spirochaete family was isolated by immunomagnetic separation with beads coated with polyclonal anti-treponemal antisera and prolonged anaerobic broth culture.
However, on the basis of 16S rDNA, the organism was found to be very closely related to another unnamed spirochaete isolated from cases of bovine digital dermatitis in the USA.

 Infectious Diseases in History   (Site not responding. Last check: 2007-11-06)
Of the types that appear in this guide, bacilli (singular: bacillus) are rod-like and straight; spirochaeta (singular: spirochaete) are long, slender, and spirally coiled; streptococci (singular: streptococcus) are spherical and tend to grow in chains; staphylococci (singular: staphylococcus) grow in 'bunches of grapes'; and vibrios are curved.
The spirochaete is able to invade any cell of the body, causing damage to organ or structure.
For instance, it may attack the central nervous system to cause loss of positional sense; the brain to bring a distinct form of insanity termed general paralysis of the insane (GPI); the eye, to cause blindness; or the heart, resulting in the failure of that organ.

 Lyme disease: scratching the surface
The excellent Comment by Ulrike Munderloh and Timothy Kurtti (Sept 17, p 962)1 describes the complex life cycle of Borrelia burgdorferi, the spirochaetal agent of Lyme disease, as it traffics between tick and mammalian hosts.
Although this might be true of promptly treated acute B burgdorferi infection, chronic infection that allows the spirochaete's complex pathophysiological mechanisms to unfold can result in tenacious tissue invasion that is extremely difficult to eradicate.

 Diagnosing the increasing incidence of syphilis: News from Oxoid
Figures from the Health Protection Agency show that between 2001 and 2002 syphilis diagnoses went up by 67% and 33% in males and females respectively and, according to the health committee report, in the last six years syphilis rates have increased by 500%.
The causative organism of syphilis is Treponema pallidum, a spirochaete which cannot be grown on culture media or in tissue culture.
The infection is normally diagnosed by the detection of antibody specific for Treponema pallidum in the patient's blood or CSF.

 Spirochaete . Enpsychlopedia
The spirochaetes (or spirochetes) are a phylum of distinctive bacteria, which have long, helically coiled cells.
The genome of spirochaetes are also highly unusual and consists of linear chromosomes and plasmids.Template:Cite journal Most spirochaetes are free-living and anaerobic, but there are numerous exceptions.For example Relapsing fever is caused by Borrelia recurrentis and Weil's disease which is caused by Leptospiractero haemorrhagiae.
It has been suggested by Lynn Margulis that eukaryotic flagella were derived from symbiotic spirochaetes, but few biologists accept this, as there is no close structural similarity between the two.

 Syphilis as a medical problem
If the discovery of the spirochaete and the implementation of the Wasserman test confirmed beyond doubt and conjecture how terribly pervasive syphilis, was, these discoveries also enabled major advances to be made towards adequate treatment.
However, it was not exactly a simple solution: it took a good deal of work to get the exact means of administration worked out, and the early trials of the drug indicated some dangerous side-effects, as might be expected when dealing with a toxic substance.
The Commission also indicated the importance of propaganda and educational work in eradicating these diseases - while syphilis was now curable, there was still no equivalent of salvarsan for gonorrhoea, which was becoming recognised as a more significant danger to personal and national health than had once been thought.

 Glossary of biotechnology and genetic engineering
Bacteria are prokaryotes, and most of them are identified by means of Gram staining (q.v.).
They are classified on the basis of their oxygen requirement (aerobic vs anaerobic) and shape (spherical = coccus; rodlike = bacillus; spiral = spirillum; comma-shaped = vibrio; corkscrew-shaped = spirochaete; filamentous).
Bacteria usually reproduce asexually, by simple cell division, although a few undergo a form of sexual reproduction, termed conjugation.
