We describe a case of intermediate leptospirosis resulting from Leptospira licerasiae infection in a traveler returning to Japan from Brazil. Intermediate leptospirosis should be included in the differential diagnosis for travelers with fever returning from South America. This case highlights the need for strategies that detect pathogenic and intermediate Leptospira species.

Background: Leptospiraceae comprise a diverse family of spirochetal bacteria, of which many are involved in infectious diseases of animals and humans. Local leptospiral diversity in domestic animals is often poorly understood. Here we describe the incidental detection of Leptospira (L.

The study about Leptospira, particularly pathogenic strain, was conducted in the flood-prone area in the Special Capital Region of Jakarta. The aim of this study was to discover and identify the serovars of pathogenic Leptospira in the environment, which might infect human during flooding. Seventy-three samples, consisted of 36 samples of environmental water and 37 samples of soil, were collected from 5 districts of Jakarta.

Pathogenic spp. is the etiological agent of leptospirosis. The high diversity among species provides an array to look for important mediators involved in pathogenesis.

serovar Varillal, a group II intermediate pathogen species/serovar discovered in the Peruvian Amazon city of Iquitos, is commonly recognized in this region by sera from humans (at least 40% seroprevalence) without a known clinical history of leptospirosis. This high frequency of human seroreactivity remains unexplained. To test the hypothesis that the oral route of infection might explain the high rate of human seroreactivity against , an experimental infection model using was developed, given that rats were one of the original reservoir hosts identified as being colonized by this leptospire.
