Leptospirosis is a blood infection caused by the bacterium Leptospira [8] that can infect humans, dogs, rodents and many other wild and domesticated animals. [8] Signs and symptoms can range from none to mild ( headaches , muscle pains , and fevers ) to severe ( bleeding in the lungs or meningitis ). [ 5 ]
Leptospirosis is treated with the antibiotics doxycycline and penicillin. [28] There are more than 200 diverse pathogenic Leptospira serovars, making it challenging to develop an effective vaccine. [31] However, vaccines for the serovars known as Hardjo, Pomona, Canicola, Grippotyphosa and icterohaemorrhagiae have been developed.
Leptospira (from Ancient Greek λεπτός (leptós) 'fine, thin, narrow, etc.' and Latin spira 'coil') [1] is a genus of spirochaete bacteria, including a small number of pathogenic and saprophytic species. [2] Leptospira was first observed in 1907 in kidney tissue slices of a leptospirosis victim who was described as having died of "yellow ...

The 2017 Puerto Rico Leptospirosis outbreak was an outbreak of leptospirosis that affected Puerto Rico in the fall of 2017, following Hurricane Maria's landfall.. Cases of infectious diseases often spike in the aftermath of intense storms, with flooding and damage to infrastructure leading to a wide variety of problems that increase the chance for transmission and exposure of infectious ...
Solomon Faine (17 August 1926 – 4 February 2021) was a New Zealand-born microbiologist known for his research on leptospirosis.With Dr. Leopold Kirschner, Faine made early epidemiologic descriptions of leptospirosis as an occupational disease of dairy farmers in New Zealand. [1]
Leptospira biflexa are a species of genus Leptospira consisting of pathogenic and free living saprophytic bacterial species. L. biflexa is a free-living saprophytic spirochete that survives exclusively in external environments and was the first saprophytic Leptospira genome to be sequenced unveiling a total of 3,590 protein-coding genes distributed across three circular replicons.

Leptospira alstonii is a gram negative, mobile, spirochete. [1] It is flexible, helical, and motile by means of two periplasmic flagella (axial fibrils). It is obligately aerobic and oxidase positive. It was named after J. M. Alston, a British microbiologist who made significant contributions to the study of Leptospirosis. [2]
