In this educational webinar, Dr. Edward Breitschwerdt will present a series of landmark clinical case studies illustrating the diverse and underrecognized manifestations of Bartonella infection. Drawing from decades of research and clinical investigation, the session highlights non-traditional transmission routes, including needlestick exposure, perinatal transmission, household spread, and tissue-localized infection, as well as the profound limitations of standard serologic and single-timepoint molecular testing.

Through cases spanning neurology, psychiatry, pediatrics, oncology, and One Health family investigations, attendees will gain practical insight into when to suspect Bartonella infection, why it frequently evades detection, and how advanced culture and molecular methods can uncover clinically relevant infection that would otherwise remain hidden.

Special focus is placed on:

• Bartonella as a stealth, low-burden intravascular pathogen
• Delayed, absent, or misleading antibody responses
• Bloodstream versus tissue-localized infection
• Diagnostic timing and test selection
• The importance of a One Health perspective in complex cases
