(microbiology)
A genus of bacteria in the family Spirochaetaceae; thin, helical cells with bent or hooked ends.

Leptospira

 

a genus of microorganisms of the family Treponemataceae; the causative agent of leptospirosis.

There are two species of Leptospira: L. interrogans (parasitic) and L. biflexa (saprophytic). Leptospira have a thin axial filament surrounded by a cytoplasmatic spiral serving as the organ of locomotion (4–8 microns [μ] long, sometimes to 20 μ; 0.10–0.25 μ wide). Pathogenic leptospira die quickly upon exposure to sunlight, high temperature, acids, alkalis, and disinfectants.

Leptospirosis is water borne disease caused by a sphirochaete bacterium called Leptospira spp.
It is caused by leptospira bacteria that enter a person's body through breaks in the skin or wounds, the eyes and nose when in contact with floodwaters, vegetation and moist soil contaminated with the urine of infected animals, especially rats.
Leptospirosis, which is caused by Leptospira bacteria, is a widespread zoonotic disease transmitted naturally from domestic and wild animals to humans, who can become infected through contact with water, food, or soil contaminated with urine from infected animals.
Patel added that rats and cattle are the permanent carriers of leptospira bacteria and humans get infected from faeces of cattle and rats that transmit the bacteria to places where water logging occurs after a spell of incessant rainfall.
All the pathogenic leptospires were formerly classified as members of the species Leptospira interrogans; the genus has recently been reorganised and pathogenic leptospires are now identified in several species of Leptospira.
