Leptospira in Working Horses From Rural Ecuador: A Neglected Occupational Risk

Journal of Tropical Medicine, Volume 2026, Issue 1, 2026.
Neglected tropical zoonotic diseases such as leptospirosis continue to have a significant impact on animal and human health, especially in low‐income countries due to limitations in surveillance and knowledge gaps to guide mitigation. In this context, equines have the potential to play an important role in the maintenance and transmission of Leptospira

Characterization of two new putative adhesins of Leptospira interrogans

Microbiology, 2017
We here report the characterization of two novel proteins encoded by the genes LIC11122 and LIC12287, identified in the genome sequences of Leptospira interrogans, annotated, respectively, as a putative sigma factor and a hypothetical protein. The CDSs LIC11122 and LIC12287 have signal peptide SPII and SPI and are predicted to be located mainly at the ...

Epidemiologic features of equine Leptospira interrogans of human significance

Preventive Veterinary Medicine, 1998
Leptospirosis is a zoonotic bacterial disease caused by Leptospira interrogans. There is a serologic evidence that horses are exposed to L. interrogans and, as a shedder of these organisms, can be a threat to humans. We examined risk factors associated with the risk of testing seropositive to three L. interrogans serovars (L.

The transcriptional response of pathogenic Leptospira to peroxide reveals new defenses against infection-related oxidative stress.

PLoS Pathogens, 2020
Pathogenic Leptospira spp. are the causative agents of the waterborne zoonotic disease leptospirosis. Leptospira are challenged by numerous adverse conditions, including deadly reactive oxygen species (ROS), when infecting their hosts.
