“…La leptospirosis se consideraba una enfermedad ocupacional y aunque esta aseveracibn a h es vilida, se ha demostrado que la infecci6n es cada vez mis com6n por actividades recreativas, puesto que el riesgo ocupacional en paises desarrollados, se ha disminuido notoriamente persistiendo a h en el irea agropecuaria por el contacto direct0 entre campesinos y animales (4, 5,8,12,15,19,20). Ahora bien, en nuestro pais no se dan condiciones de alto desarrollo por lo tanto el riesgo de infecci6n es mayor, sobre todo a nivel agropecuario dado el elevado porcentaje de animales domCsticos y silvestres infectados en nuestra zona (1,23,24).…”

Resumen Se realizó una prospección serológica en 239 campesinos de la zona sur de Chile, con el fin de pesquisar la existencia de anticuerpos frente a diferentes serotipos de leptospiras. Del total de muestras analizadas 47 (19,67%) resultaron positivas, de las cuales la mayoría lo hizo a títulos bajos, siendo mayor el número de reaccionantes en hombres que en mujeres y también en aquellos que desempeñan labores pecuarias. Los serotipos que reaccionaron más frecuentemente a las pruebas serológicas fueron en orden decreciente: pomona, hardjo e icterohaemorrhagiae. Zusammenfassung Epidemiologische Aspekte der menschlichen Leptospirose auf ländlichem Milieu Bei 239 Bewohnern auf dem Lande der Südzone Chiles wurde eine serologische Untersuchung durchgeführt mit dem Zweck, das Vorhandensein von Antikörpern gegen verschiedene Leptospiraserotypen nachzuforschen. Es stellte sich heraus, daß von der Summe der untersuchten Proben 47 (19,67 %) positiv waren; die Mehrheit davon hatte niedrige Titer. Die Anzahl der Reagenten war bei Männern größer als bei Frauen sowie auch bei denen, die beim Vieh arbeiteten. Die am häufigsten bei den serologischen Proben reagierenden Serotypen waren, in abnehmender Reihenfolge, folgende: pomona, hardjo und icterohaemorrhagiae. Summary Epidemic aspects of human leptospirosis in rural areas (Chile) In 239 inhabitants in southern Chile a serological study was carried out to detect antibodies against various Leptospira serotypes. It was found that 47 (19.67 %) of the samples were positive, most of them having a low titre. The number of reactors was higher in men than in women and also in persons who worked with cattle. The most often found serotypes, in descending frequency, were pomona, hardjo and icterohaemorrhagiae.

Leptospirosis and the Environment: A Review and Future Directions

Leptospirosis is a zoonotic disease of global importance with significant morbidity and mortality. However, the disease is frequently overlooked and underdiagnosed, leading to uncertainty of the true scale and severity of the disease. A neglected tropical disease, leptospirosis disproportionately impacts disadvantaged socioeconomic communities most vulnerable to outbreaks of zoonotic disease, due to contact with infectious animals and contaminated soils and waters. With growing evidence that Leptospira survives, persists, and reproduces in the environment, this paper reviews the current understanding of the pathogen in the environment and highlights the unknowns that are most important for future study. Through a systematic Boolean review of the literature, our study finds that detailed field-based study of Leptospira prevalence, survival, and transmission in natural waters and soils is lacking from the current literature. This review identified a strong need for assessment of physical characteristics and biogeochemical processes that support long-term viability of Leptospira in the environment followed by epidemiological assessment of the transmission and movement of the same strains of Leptospira in the present wildlife and livestock as the first steps in improving our understanding of the environmental stage of the leptospirosis transmission cycle.
