The pathogenesis of ''Leptospira'' depends on virulence of the bacteria and susceptibility of the host. Leptospires invade tissues through moist skin or via mucous membranes, aided by their motility. They may invade via receptor-mediated endocytosis and then pass through the body via the blood stream. Antibodies clear the organisms from the blood stream after about 10 days of infection.

The organisms may persist in the renal tubules, uterus, eye or meninges. They evade phagocytosis possibly via macrophage apoptosis and damage red blood cell membranes and endothelial and liver cells, leading to haemolytic anaemia, jaundice, [[Pigmentation and Calcification - Pathology#Haemoglobin|haemoglobin pigmentation]], haemoglobinuria and haemorrhage in acute leptospirosis.

The fluorescent antibody technique can be used for identification in tissues. Silver impregnation, molecular techniques such as PCR and Serology using microscopic agglutination test or ELISA can also be used.
