Leptospirosis is induced by pathogenic Spirochaetales, belonging to the genus Leptospira. Now this genus is divided in several genomospecies : at least 7 for the pathogenic strains. But up to now, for experimental diagnosis and epidemiological studies, the serological classification was still used. This type of classification is based on agglutinating antibodies produced by animals infected by this bacteria. So the genus Leptospira was divided in 2 species, the saprophytic one L. biflexa s.l. and the pathogenic L. interrogans s.l. The basic taxon is the serovar. Because of close antigenic communities, several serovars are gathered in a serogroup (Usually, names of serovars and serogroups are written in roman but for the serogroup, the first letter is a capital). Each of the strains of L. interrogans s.l could induce leptospirosis. Leptospires in contaminated material may infect a man or another Mammal. Penetrating in the blood vessels, they multiply and reach several

European consensus statement on leptospirosis in dogs and cats.

Leptospirosis is a zoonotic disease with a worldwide distribution affecting most mammalian species. Clinical leptospirosis is common in dogs but appears to be rare in cats. Both dogs and cats, however, can shed leptospires in the urine. This is problematic as it can lead to exposure of humans. The control of leptospirosis, therefore, is important not only from an animal but also from a public h...
