Bartonellosis (Cat-Scratch Disease)


Cats and Humans, but may also be carried by Dogs, Cattle, and Rodents

Overview / Symptoms

  • Caused by Bartonella henselae, a type of bacteria spread through contact with infected cats (via bites or scratches) or through exposure to cat fleas
  • Human symptoms include bumps or blisters at the site of injury, fatigue, fever, headache, swelling of lymph nodes near site of injury, and malaise
  • Typically clears without treatment in healthy humans, but may need to be treated with antibiotics in some cases
  • More serious for people with compromised immune systems, such as AIDS patients
  • Cats become infected through the bites of infected fleas or via cat fights
  • Dogs (both wild and domestic), cattle, and rodents may carry other species of Bartonella, but it is not known if these can be transmitted to humans
