          Abstract

          Leptospirosis is a neglected zoonotic disease. In 2015, leptospirosis was diagnosed in 2 prison inmates in South Africa. Using real-time PCR and DNA sequencing, we identified Leptospira interrogans serogroup Icterohaemorrhagiae in rodents and water samples within the prison. Leptospirosis might be frequently underdiagnosed in South Africa.

          Virulence of the zoonotic agent of leptospirosis: still terra incognita?

          Pathogenic leptospires are the bacterial agents of leptospirosis, which is an emerging zoonotic disease that affects both animals and humans worldwide. In this Review, the recent advances in our understanding of the epidemiology, taxonomy, genomics and the molecular basis of virulence in leptospires, and of how these properties contribute to the pathogenesis of leptospirosis, are discussed.

            Rapid tests for diagnosis of leptospirosis: current tools and emerging technologies.

            Leptospirosis is an emerging zoonosis with a worldwide distribution but is more commonly found in impoverished populations in developing countries and tropical regions with frequent flooding. The rapid detection of leptospirosis is a critical step to effectively manage the disease and to control outbreaks in both human and animal populations. Therefore, there is a need for accurate and rapid diagnostic tests and appropriate surveillance and alert systems to identify outbreaks. This review describes current in-house methods and commercialized tests for the rapid diagnosis of acute leptospirosis. It focuses on diagnostic tests that can be performed with minimal training and limited equipment in less-developed and newly industrialized countries, particularly in resource-limited settings and with results in minutes to less than 4 hours. We also describe recent technological advances in the field of diagnostic tests that could allow for the development of innovative rapid tests in the near future. © 2013 Elsevier Inc.

              Mixed Leptospira Infections in a Diverse Reservoir Host Community, Madagascar, 2013–2015

              We identified mixed infections of pathogenic Leptospira in small mammals across a landscape-scale study area in Madagascar by using primers targeting different Leptospira spp. Using targeted primers increased prevalence estimates and evidence for transmission between endemic and invasive hosts. Future studies should assess rodentborne transmission of Leptospira to humans.
