Research

• Tick-borne Relapsing Fever and Borrelia hermsii, Los Angeles County, California, USA
  The primary cause of tick-borne relapsing fever in western North America is Borrelia hermsii, a rodent-associated spirochete transmitted by the fast-feeding soft tick Ornithodoros hermsi. We describe a patient who had an illness consistent with relapsing fever after exposure in the mountains near Los Angeles, California, USA.
  
• Tick-borne Pathogens in Northwestern California, USA
  From a total of 1,180 adult ticks, we found 43 samples positive for Borrelia spp., resulting in a minimum infection prevalence of 3.6%
• Canine Tick-Borne Pathogens in Cyprus and a Unique Canine Case of Multiple Co-Infections Canine tick-borne pathogens such as Ehrlichia canis and Hepatozoon canis are widespread in the Mediterranean basin but have never been reported or investigated in Cyprus
• CHANGING PARADIGMS FOR TICK-BORNE DISEASES IN THE AMERICAS 
  Ticks transmit a greater diversity of viral, bacterial, and protozoan diseases than any other arthropod vector on earth (Jongejan and Uilenberg, 2004; IOM, 2011). Through 2014, at least 27 ecologically and epidemiologically distinct tickborne diseases were identified in the Western Hemisphere; remarkably, nearly half of these were discovered during the last 20 years (see Table A8-1). Against this background of expanding pathogen recognition are also unprecedented surges in the incidence of several tick-borne infections throughout the Americas.
• Bartonella henselae prevalence in domestic cats in California: risk factors and association between bacteremia and antibody titers.
  The isolation of Bartonella henselae, the agent of cat scratch disease, from the blood of naturally infected domestic cats and the demonstration that cats remain bacteremic for several months suggest that cats play a major role as a reservoir for this bacterium.
• Bartonella spp. DNA associated with biting flies from California.
  Bartonella DNA was investigated in 104 horn flies (Haematobia spp.), 60 stable flies (Stomoxys spp.), 11 deer flies (Chrysops spp.), and 11 horse flies (Tabanus spp.) collected on cattle in California. Partial sequencing indicated B. bovis DNA in the horn fly pool and B. henselae type M DNA in one stable fly.
  
• Experimental transmission of Bartonella henselae by the cat flea.
  Bartonella henselae is an emerging bacterial pathogen, causing cat scratch disease and bacillary angiomatosis. Cats bacteremic with B. henselae constitute a large reservoir from which humans become infected.
  
• Human Granulocytic Ehrlichiosis in Northern California: Two Case Descriptions
  with Genetic Analysis of the Ehrlichiae
  We report two cases of human granulocytic ehrlichiosis (HGE) that occurred in northern California in summer 1998. Patients had fever, malaise, and myalgia, reported tick
