Historical distribution and host-vector diversity of Francisella tularensis, the causative agent of tularemia, in Ukraine
Abstract Background Francisella tularensis, the causative agent of tularemia, is a zoonotic agent that remains across much of the northern hemisphere, where it exists in enzootic cycles.In Ukraine, tularemia has a long history that suggests a need for sustained surveillance in natural foci.To better characterize the host-vector diversity and spatia
