The symptoms associated with cellulitis usually occur within 24 hours after getting bitten or scratched. Patients may develop the following:

  • Swelling and redness
  • High body temperature
  • Tenderness of the skin
  • Possible discharge of puss
  • Lymph nodes in the affected skin area may become enlarged
  • Chills and fever

Where to learn more


Pasteurellosis is a bacterial infection caused by a bite or scratch from animals – mostly cats. It often causes cellulitis once the Pasteurella multocida bacteria enter the bloodstream through the broken skin.

People who spend a lot of time with cats and dogs are more at risk of contracting the disease. Once infected, patients may experience swelling and redness, high body temperature, tenderness of the skin, possible discharge of puss, lymph nodes in the affected skin area may become enlarged, and chills and fever.

Possible complications that may be caused by this condition include septicemia, meningitis, respiratory tract infection, appendicitis, liver abscess, and peritonitis, to name a few.

By eating foods and consuming nutrients that can help in strengthening the immune system, there’s a better chance of fighting off the bacteria and infection caused by pasteurellosis. As for treatment, it’s vital to immediately clean the wound and apply antibacterial cream to prevent further infection.

Getting the wound checked by a healthcare provider is also important to ensure that there are no complications.
