The incidence of Lyme disease has continued to rise despite attempts to control its spread. Vaccination of zoonotic reservoirs of human pathogens has been successfully used to decrease the incidence of rabies in raccoons and foxes. We have previously reported on the efficacy of a vaccinia virus vectored vaccine to reduce carriage of Borrelia burgdorferi in reservoir mice and ticks. One potential drawback...
Immunization with the Ixodes scapularis protein, subolesin, has previously been shown to protect hosts against tick infestation and to decrease acquisition of Anaplsma marginale and Babesia bigemina. Here we report the efficacy of subolesin, a conserved tick protein that can act as a regulator of gene expression, expressed from vaccinia virus for use as an orally delivered reservoir – targeted vaccine...
Lyme disease is a major human health problem which continues to increase in incidence and geographic distribution. As a vector-borne zoonotic disease, Lyme disease may be amenable to reservoir targeted strategies for control. We have previously reported that a vaccinia virus (VV) based vaccine expressing outer surface protein A (OspA) of Borrelia burgdorferi, the causative agent of Lyme disease, protects...
Studies of the protein function of Borrelia burgdorferi have been limited by a lack of tools for manipulating borrelial DNA. We devised a system to study the function of a B. burgdorferi oligopeptide permease (Opp) orthologue by complementation with Escherichia coli Opp proteins. The Opp system of E. coli has been extensively studied and has well defined substrate specificities. The system is of interest...
