|Title:||Baccilary Angiomatosis: Negative Results Using Normal Balb/c And Balb/c Nude Mice.|
|Abstract:||Baccilary angiomatosis has recently been described as a disease that can spread systematically and that is potentially fatal. It is caused by Bartonella henselae and B. quintana, and presents as especially pronounced signs and symptoms in patients suffering from acquired immunodeficiency syndrome (AIDS). To clarify the pathogenesis of the disease and to try to define the relationships among baccilary angiomatosis, cat scratch disease and Carrión's bartonellosis, the authors of this study have attempted to develop an experimental model using mice that were immunocompetent as well as those that had their cellular immunity genetically compromised. A known concentration of B. henselae was inoculated intradermally in Balb/c an isogenic mice or an athymic group of the same lineage. Blood samples were taken on days 0, 3, 7, 10, 14, 28, and 60 after inoculation for indirect immunofluorescence antibody testing. On the 21st and 60th day, one animal from each group was sacrificed and a post mortem carried out including histological evaluation of the liver, spleen, lymph nodes, skin and other organs. Hemocultures of the sacrificed animals were collected. All results of serologic response, cultures and histologic examination were negative. The authors discuss the methodology, especially the use of isogenic animals of the same lineage in B. henselae infection, with and without immunodeficiency, and the resources for the negative results of histopathology, serology and cultures.|
