Topic: Bartonella Henselae


In the News (Fri 25 Dec 09)

  
  Bartonella henselae
henselae ranges from 0.3 to 0.6 by 0.3 to 1.0 nm and its optimum temperature is greater than 38 degrees celsius.
henselae is a slow growing organism so when it is cultured from blood, lymph nodes, or other tissue it takes nine to forty days for colonies to appear.
henselae causes endocaritis which is vegetation of bacteria on the surface of the endocardium or in the endocardium itself.

 Bartonella
In fact, it involves infection by a bacterium called “Bartonella henselae” which is spread by fleas.
Infection with Bartonella henselae in the immunocompetent person leads to “cat scratch disease.” The innoculation site (a bite or scratch) develops a small red bump (a “papule.”) About 2-3 weeks following contact with the infected cat, the lymph node in the area of the contact will swell and become painful and a fever develops.
It has been suggested that Bartonella infection may be a the root of numerous chronic inflammatory conditions of the cat.
