Clinical Utility

Leptospirosisis a geographically widespread disease that humans acquire through contact of skin or mucous membranes with contaminated animal urine. Contaminated water or unclean food preparation surfaces are also possible sources of infection. Leptospirosisis an acute febrile illness caused by members of the genus Leptospira, which includes over 200 serovars. Most infections occur between July and October. Symptoms range from respiratory inflammation to icteric disease involving the kidneys and liver. Leptospira Biflexa-a is a non-pathogenic species that has broad cross-reactivity across the genus, thus it is the organism of choice for detecting anti-Leptospira antibodies in serum.
