Read the detailed description

Approximately 20 volunteers who have received a liver transplant and have been diagnosed with cryptogenic cirrhosis will be included in this study. Blood samples will be analyzed for Bartonella using the state-of-the art Bartonella Alpha Proteobacterium Growth Medium (BAPGM) multi-platform testing, including liquid culture, enriched agar plating and molecular techniques. Blood smears will be analyzed for intra-erythrocytic Bartonella spp. Four-millimeter skin biopsies from non-lesional skin will be acquired from the same patients, processed using our published techniques, and imaged using confocal microscopy and compared to BAPGM test results. additionally, urine samples will be collected and analyzed for microRNAs.

    Four-mm skin biopsies from non-lesional skin will be acquired from the patients, processed using our published techniques with Bartonella biomarkers, and imaged using confocal microscopy.

  • OtherBlood collection

    Blood will be tested for presence of Bartonella DNA and Bartonella antibodies using the Alpha Proteobacterium Growth Medium (BAPGM) multi-platform testing, including liquid culture, enriched agar plating and molecular techniques.Blood smears will be analyzed for presence of intra-erythrocytic Bartonella spp. by immunostaining.
