Cat scratch disease : Overview, Causes, & Risk Factors

Alternate Names : CSD, Cat scratch fever, Bartonellosis

Definition

Cat scratch disease is a disease caused by bartonella bacteria. It is believed to be transmitted by cat scratches and bites, or exposure to cat saliva.

Overview, Causes, & Risk Factors

Cat scratch disease is caused by Bartonella henselae. The disease is spread through contact with an infected cat (a bite or scratch), or contact with cat saliva on broken skin or the white of the eye.

About 2 – 3 weeks after becoming infected, lymph node swelling (lymphadenopathy) occurs near the site of the scratch or bite.

Occasionally, an infected lymph node may form a tunnel (fistula) through the skin and drain (leak fluid). Cat scratch disease is a common cause of chronic swollen lymph nodes in children.

Antibodies

Antigens are large molecules (usually proteins) on the surface of cells, viruses, fungi, bacteria, and some non-living substances such as toxins, chemicals, drugs, and foreign particles. The immune system recognizes antigens and produces antibodies that destroy substances containing antigens.
