25. Delayed Invasion of the Kidney and Brain by Borrelia crocidurae in Plasminogen-Deficient Mice
Borrelia crocidurae is an etiologic agent of relapsing fever in Africa and is transmitted to humans by the bite of soft ticks of the genus Ornithodoros. The role of the plasminogen (Plg) activation system for the pathogenicity of B. crocidurae was investigated by infection of Plg-deficient (plg−/−) and Plg wild-type (plg+/+) mice. No differences in spiro

26. Characterization of Borrelia coriaceae antigens with monoclonal antibodies.
Three monoclonal antibodies (F6F3, F6B11, and F6B3) were developed against Borrelia coriaceae antigens. All three antibodies appeared to be specific for this species and did not cross-react with Borrelia burgdorferi (strains B31 and IRS), Borrelia hermsii, Borrelia anserina, Leptospira interrogans serovar hardjo, or Treponema hyodysenteriae, as determined by

27. Endosymbionts of ticks and their relationship to Wolbachia spp. and tick-borne pathogens of humans and animals.
The presence, internal distribution, and phylogenetic position of endosymbiotic bacteria from four species of specific-pathogen-free ticks were studied. These included the hard ticks Ixodes scapularis (the black-legged tick), Rhipicephalus sanguineus (the brown dog tick), and Haemaphysalis longicornis and the African soft tick Ornithodoros moubata.
