There are several microorganisms that can cause lung lesions in patients infected by the human immunodeficiency virus (HIV) like Mycobacterium tuberculosis, Pneumocystis carinii or Staphylococcus aureus, among others. Rhodococcusequi is an emergent microorganism associated to opportunistic infections in immunocompromised individuals, especially in patients with Acquired Immune Deficiency Syndrome (AIDS). There is not an established regimen to treat this microorganism, neither the duration of it. This report describes a case of Rhodococcusequi lung infection in a HIV patient.
