  1. Barbour A, Restrepo B. Antigenic variation in vector-borne pathogens. Emerg Infect Dis. 2000;6:449-57 pubmed
    ..Antigenic variation poses a challenge in the development of vaccines against vector-borne pathogens. ..
  2. Barbour A, Bundoc V. In vitro and in vivo neutralization of the relapsing fever agent Borrelia hermsii with serotype-specific immunoglobulin M antibodies. Infect Immun. 2001;69:1009-15 pubmed
    ..The study established that a Vlp protein was the target of a neutralizing antibody response, and it also indicated that the conformation and/or the native topology of Vlp were important for eliciting that immunity. ..
  3. Barbour A, Bunikis J, Fish D, Hanincová K. Association between body size and reservoir competence of mammals bearing Borrelia burgdorferi at an endemic site in the northeastern United States. Parasit Vectors. 2015;8:299 pubmed publisher
    ..These empirical findings as well as inferences from modeling suggest that small mammals on the basis of their sizes are more competent as reservoirs of B. burgdorferi in this environment than medium-to large-sized mammals. ..
  4. Barbour A, Jasinskas A, Kayala M, Davies D, Steere A, Baldi P, et al. A genome-wide proteome array reveals a limited set of immunogens in natural infections of humans and white-footed mice with Borrelia burgdorferi. Infect Immun. 2008;76:3374-89 pubmed publisher
    ..These results indicate that the majority of deduced proteins of B. burgdorferi do not elicit antibody responses during infection and that the limited sets of immunogens are similar for two different host species. ..
  5. Cook V, Barbour A. Broad diversity of host responses of the white-footed mouse Peromyscus leucopus to Borrelia infection and antigens. Ticks Tick Borne Dis. 2015;6:549-58 pubmed publisher
    ..The study demonstrated the diversity of host responses to infection and immunization in this species and identified quantitative traits that may be suitable for forward genetics approaches to reservoir-pathogen interactions. ..
  6. Krause P, Fish D, Narasimhan S, Barbour A. Borrelia miyamotoi infection in nature and in humans. Clin Microbiol Infect. 2015;21:631-9 pubmed publisher
    ..Antibiotics that have been used effectively include doxycycline for uncomplicated B. miyamotoi infection in adults and ceftriaxone or penicillin G for meningoencephalitis. ..
  7. Norris S, Barbour A, Fish D, Diuk Wasser M. Response to Esteve-Gassent et al.: flaB sequences obtained from Texas PCR products are identical to the positive control strain Borrelia burgdorferi B31. Parasit Vectors. 2015;8:310 pubmed publisher
    ..burgdorferi B31 positive control strain. ..
  8. Barbour A, Travinsky B. Evolution and distribution of the ospC Gene, a transferable serotype determinant of Borrelia burgdorferi. MBio. 2010;1: pubmed publisher
  9. Barbour A, Putteet Driver A, Bunikis J. Horizontally acquired genes for purine salvage in Borrelia spp. causing relapsing fever. Infect Immun. 2005;73:6165-8 pubmed
    ..These were located among the rRNA genes. Phylogenetic analysis indicated that these genes had a different evolutionary history than those of orthologs in other spirochetes. ..
