Denouement and Comment: Cat-Scratch Disease

Shortly after the biopsies were performed, the child's father was available to provide additional history. The father was scratched by the family's kitten shortly after its acquisition 1 month before. He was given penicillin prophylaxis. He developed a fever and axillary lymphadenopathy 1 week later, a course of illness that suggested cat-scratch disease.

Pathologic specimens demonstrated small, rodlike organisms on Warthin-Starry staining of the lymph node (Figure 3B, inset). The B henselae genome was detected by polymerase chain reaction testing of the muscle tissue. Convalescent B henselae serology remained at the same titers (IgM < 1:16; IgG, 1:128) as during the acute phase of the illness. Cat-scratch disease is a well-known cause of fever and lymphadenopathy in children. The causative agent, B henselae, is a pleomorphic, aerobic, gram-negative bacterium commonly found in the oral flora of cats and kittens as well as other animals.¹
