Abstract
Understanding the ecological factors that drive the spatial patterns of parasites transmission is essential to predict their distribution under global change and to direct proactive surveillance efforts. Here, we systematically reviewed the literature to assess the main ecological drivers responsible for the spatial distribution and transmission of the zoonotic cestode Echinococcus multilocularis, the aetiological agent of alveolar echinococcosis, focusing on wild hosts. The 23 retrieved studies suggested that the dispersal of definitive hosts, climatic and biotic factors (distribution of intermediate hosts, composition of host communities) shape continental-scale distribution patterns of E. multilocularis, whereas the relative importance of climate and land cover in driving E. multilocularis distribution at a smaller (country/regional) scale varies with the geographic area considered. At a local scale, two additional factors contribute to determine the distribution of micro-foci of transmission: the trophic relationships between carnivores definitive hosts and small mammals intermediate hosts, and the defecation and marking behaviour of definitive hosts.
期刊介绍：
Food and Waterborne Parasitology publishes high quality papers containing original research findings, investigative reports, and scientific proceedings on parasites which are transmitted to humans via the consumption of food or water. The relevant parasites include protozoa, nematodes, cestodes and trematodes which are transmitted by food or water and capable of infecting humans. Pertinent food includes products of animal or plant origin which are domestic or wild, and consumed by humans. Animals and plants from both terrestrial and aquatic sources are included, as well as studies related to potable and other types of water which serve to harbor, perpetuate or disseminate food and waterborne parasites. Studies dealing with prevalence, transmission, epidemiology, risk assessment and mitigation, including control measures and test methodologies for parasites in food and water are of particular interest. Evidence of the emergence of such parasites and interactions among domestic animals, wildlife and humans are of interest. The impact of parasites on the health and welfare of humans is viewed as very important and within scope of the journal. Manuscripts with scientifically generated information on associations between food and waterborne parasitic diseases and lifestyle, culture and economies are also welcome. Studies involving animal experiments must meet the International Guiding Principles for Biomedical Research Involving Animals as issued by the Council for International Organizations of Medical Sciences.
