Can you identify the bacteria?!

While doing the virtual lab, I was a little confused at what we were supposed to be doing and so I just followed through the motions without a clue.  After doing it I quickly learned I was soon to be identifying some type of bacteria.  After going through all of the steps I learned the bacteria I was dealing with was Bartonella henselae.  Many species of Bartonella able to cause disease in humans are transmitted by a vector, or directly from an animal reservoir.

Common Bartonella sicknesses

  • B. bacilliformis by sandflies causes Oroya fever. 
  • B. quintana from body lice causes trench fever
  • B. henselae from cats causes cat scratch disease (CSD)
    • it generally reveals as lymph glands swelling, possible skin lesions at the site of inoculation and may be joined with fever, fatigue, and other symptoms.
  • Patients can be susceptible and and develop a different disease called bacillary angiomatosis, caused by infection of B. henselae or B. quintana.
