全球麦地那龙线虫根除规划已将4个国家的麦地那龙线虫病（麦地那龙线虫病）人间感染人数减少到49例。然而，家畜（狗和猫）的感染最近已被确认，并且正在增加。通常，麦地那龙线虫（麦地那龙线虫）通过从水中摄入桡足类动物传播。尽管采取了一些干预措施，包括在出现蠕虫时将狗拴起来，但受感染的狗的数量继续增加。一种假设是，狗可能通过摄入供应水中的桡足类动物而感染。目的研究桡足类动物在乍得典型温度条件下能否在水容器中存活。方法在塑料、玻璃、葫芦和金属四种容器中播种桡足类动物，并置于模拟乍得温度下。结果金属容器中的桡足类在4 h内全部死亡，而塑料容器、玻璃容器和葫芦容器中8 h后仍有活桡足类存在。结论提供的水是为潜在宿主提供的。金属容器为桡足类动物创造了最不适宜生存的环境。塑料容器对桡足动物的死亡率几乎没有影响。使用金属容器盛水可能是一种有用的工具，有助于中断脱水。犬类间的麦地那氏传播。
IntroductionThe global Guinea Worm Eradication Program has reduced numbers of human infections of Guinea worm disease (dracunculiasis) to 49 cases in four countries. However, infections of domestic animals (dogs and cats) have recently been recognized and are increasing. Typically, Guinea worm (Dracunculus medinensis) transmission occurs via the ingestion of copepods from water. Despite several interventions, including tethering of dogs while worms emerge, the number of infected dogs continue to increase. One hypothesis is that dogs could be infected through the ingestion of copepods in provisioned water.ObjectivesThe purpose of this study was to determine whether copepods can survive in water containers under typical Chadian temperatures.MethodsFour container types (plastic, glass, gourd, and metal) were seeded with copepods and exposed to simulated Chadian temperatures.ResultsAll copepods in the metal containers died within 4 h. Conversely, after 8 h live copepods were still present in plastic, glass, and gourd containers.ConclusionsIf provisioned water is provided to potential hosts ofD. medinensis, metal containers create the most inhospitable environment for copepods. Plastic containers have little effect on copepod mortality. The use of metal containers for water provisions could be a useful tool assisting with the interruption ofD. medinensistransmission among dogs.
