Aplicação do conceito One Health na área hiperendêmica de fasciolíase humana do Altiplano Boliviano: biologia dos limneídeos, dinâmica populacional, …

Abstract Fascioliasis is a freshwater snail-borne zoonotic disease. The Northern Bolivian Altiplano is a very high altitude endemic area where the highest human prevalences and intensities have been reported. Preventive chemotherapy by treatment campaigns is yearly applied. However, liver fluke infection of cattle, sheep, pigs and donkeys assures endemicity and consequent human infection and re-infection risks. A One Health action has therefore been implemented. Activity concerns lymnaeid vectors and environment diversity. Studies included growth, egg-laying and life span in laboratory-reared lymnaeids. Different habitat types and influencing factors were assessed. All populations proved to…
Capparis spinosa (Capparaceae); A Survey on Morpho-ecologic Variation for Different Populations of Iran
2021
Capparis spinosa grows naturally from the Atlantic coast of the Canary Islands and Morocco to the Black Sea, in Crimea and Armenia, and to the east side of the Caspian Sea in Iran. Capparis species are valuable as a resource for medicine, food, improving soil fertility, stabilizing dunes, fuel, timber, and livestock feed. In this research, sixteen populations of Capparis spinosa were collected from different locations in Iran and quantitative and qualitative data of morphological characters were revised. A multivariable statistical analysis was performed for the morphological characters of Capparis populations. The populations were classified into two main groups using a Ward's hierarchical…

Effect of Land-Use Change on the Changes in Human Lyme Risk in the United States
2022
The spatial extent and incidence of Lyme disease is increasing in the United States, particularly in the Upper Midwest and Northeast. Many previous studies have explored the drivers of its spatial pattern, however, few studies tried to explore the drivers for the changes of Lyme disease. We here compared the spatial patterns of changes of human Lyme cases and incidence in the Northeast and Upper Midwest between 2003–2005 and 2015–2017, and applied two different approaches (i.e., a statistical regularization approach and model averaging) to investigate the climatic and landscape factors affecting the risk change between the two periods. Our results suggested that changes in land-use variable…
