The present study, the first to spatially characterize Leptospira spp.Abstract:
The present study, the first to spatially characterize Leptospira spp. infection among equids in the Brejo Paraibano micro-region of the Paraiba state in the northeast of Brazil, investigated 257 animals in 26 farms properties. Serum samples from 204 horses, 46 mules and seven donkeys were serologically diagnosed using the microscopic agglutination test (MAT). The distribution of Leptospira spp. was studied by employing specific antigens from 24 different Leptospira serovars. All farms were georeferenced and their distribution visualised on a map of the Brejo Paraibano micro-region. In addition, rainfall data were obtained from the same year, in which the sampling was performed. Among the 20 farms found to harbour animals with leptospirosis, 14 (70%) exhibited low prevalence, five (25%) medium prevalence and one (5%), high prevalence. Certain areas had a higher density of infected farms and required intervention to control the infection. Many serovars were widely distributed, while others were more common in particular areas. There was no significant association between the prevalence of Leptospira spp. infection and rainfall.read more

TL;DR: A general framework for the application of spatial analytical tools for leptospirosis was proposed and the quality of the epidemiological data, the selection of covariates and spatial analytical techniques should be carefully considered in future studies to improve usefulness of evidence as tools to support leptosphereirosis control.

TL;DR: Assessment of geographic and ecological features among Leptospira serovars in a subtropical area of Brazil where leptospirosis is endemic to highlight environmental conditions that facilitate or limit Leptonospira spread and survival and reconstruct its geographical distribution is suggested.

Geoprocessing and spatial analysis for identifying leptospirosis risk areas: a systematic review.
TL;DR: The results point to a progressive interest of health professionals in applying these techniques for monitoring and conducting epidemiological analyses of leptospirosis, besides indicating a greater need for intersectoral integration between health professionals and others, in the use of spatial analysis and GIS techniques.

Equine leptospirosis: Experimental challenge of Leptospira interrogans serovar Bratislava fails to establish infection in naïve horses
Tiago J. Zilch,Jen‐Jie Lee,Muhammad Zain Saleem,Hui Zhang,Hui Zhang,Victor S. Cortese,Nathan Voris,Sean P. McDonough,Thomas J. Divers,Yung-Fu Chang +9 more
TL;DR: Differences between groups were found in CBC, differential counts and serum biochemistry panel (or profile), suggesting that leptospiral challenge triggered an inflammatory response, and it may suggest that L. interrogans serovar Bratislava is neither pathogenic nor host-adaptedserovar for horses, although these results might have varied if another strain from the same serovars had been used instead.

Are geoprocessing, environment, and health a possible combination?
TL;DR: The use of geoprocessing techniques allows one to gather socioeconomic, health, and environmental data on a spatial basis, however, interpretation of associations between epidemiological and environmental variables requires the geop rocessing system design.

TL;DR: Intervention measures for the prevention of canine leptospirosis should include reducing access to potentially infectious bodies of water that are close to canine homes, and to large areas of wetlands and public open space in the general vicinity.

Leptospira seroprevalence and associations between seropositivity, clinical disease and host factors in horses.
TL;DR: The results suggest that horses with increasing age and exposed to factors associated with outdoor life had an increased seroprevalence for sv Bratislava, indicating that horses get infected from outdoor and/or are exposed to shedding from other horses (management dependent).
