It is characterized by a rash, unlike other Leptospira infections.

Genetically different leptospira organisms may be identical serologically and vice versa.

Leptospira was first observed in 1907 from a post mortem renal tissue slice.

Leptospirosis is caused by a spirochaete bacterium called Leptospira spp.

Over the weekend, to Dr. Zaki's surprise, leptospira spirochetes showed up on the tests from among the four patients.

Leptospira, together with the genera Leptonema and Turneria, is a member of the family Leptospiraceae.

The corkscrew-shaped Leptospira interrogans has been on earth as long as its host mammals - mostly dogs, pigs, cattle and rats.

As a large panel of different leptospira need to be subcultured frequently, which is both laborious and expensive, it is underused, mainly in developing countries.

Leptospira interrogans is a Gram negative, obligate aerobe spirochete, with periplasmic flagella.

Leptospira pomona (abdominal pain, muscle pain, vomiting, fever)

Leptospira noguchii is a pathogenic species of Leptospira.

Leptospirosis comes from standing water containing urine from animals infected with leptospira, and the disease can be transmitted to humans via contaminated water or food.

Leptospira, both pathogenic and saprophytic, can occupy diverse environments, habitats and life cycles; these bacteria are found throughout the world, except in Antarctica.

Leptospira are aerobes whose major carbon and energy source during in vitro growth is long-chain fatty acids, which are metabolized by beta-oxidation.

It is worth noting that not all bacteria are removed by 0.2 micron (micrometer) pump filters; for example, strands of thread-like Leptospira spp.

Leptospira bacteria are spread in urine by many wild and domestic animals like rodents, swine and cattle; the urine can contaminate drinking water.

The organism that causes it, Leptospira Ictero- haemorrhagae, is carried by rats and conveyed to man in their urine, either through the skin or alimentary tract.

The outer membrane of Leptospira, like those of most other Gram-negative bacteria, contains lipopolysaccharide (LPS).

Growth of pathogenic Leptospira in an artificial nutrient environment such as EMJH becomes noticeable in 4-7 days; growth of saprophytic strains occur within 2-3 days.

Leptospira are typically cultivated at 30 C in Ellinghausen-McCullough-Johnson-Harris (EMJH) medium, which can be supplemented with 0.21% rabbit serum to enhance growth of fastidious strains.

But the scientists emphasized that the findings were very preliminary and that they needed to test many more people to be sure the illnesses were due to infection with the leptospira spirochete, a form of bacteria.

Leptospira can be cultured in Ellinghausen-McCullough-Johnson-Harris medium, which is incubated at 28 to 30 C. The median time to positivity is three weeks with a maximum of three months.

At its 2002 meeting, the Committee on the Taxonomy of Leptospira of the International Union of Microbiological Societies approved the following nomenclature for serovars of Leptospira.
