Infective endocarditis with glomerulonephritis associated with cat chlamydia (C. psittaci) infection

A patient with glomerulonephritis and endocarditis is described who had evidence of feline Chlamydia psittaci infection. Treatment with antichlamydial drugs resulted in resolution of the glomerulonephritis and the endocarditis. It is recommended that screening for chlamydia is included in the investigation of patients with suspected or obscure endocarditis.
