Nocardiosis is an uncommon Gram-positive bacterial infection caused by aerobic actinomycetes in the genus Nocardia. Nocardia spp. have the ability to cause localized or systemic suppurative disease in humans and animals. Nocardiosis is typically regarded as an opportunistic infection, but approximately one-third of infected patients are immunocompetent. We report a rare case of pulmonary nocard...

Nocardiosis has been reported increasingly in recent two decades, probably due to improvement in isolation of the organism and increased burden of immune compromised patients. Nocardia occasionally has been reported in healthy people. A case series of definitive Nocardiosis (2002 to 2010), clinical characteristics, underlying diseases, immune status and in-patient outcome were studied in a tert...

Although Nocardiosis has considerable recurrence and mortality rates, characteristics and risk factors of Nocardia infection have not been assessed in patients with rheumatic diseases. Here, we examined the characteristics and risk factors of Nocardia infection in rheumatic disease patients in our hospital. Ten rheumatic disease patients who developed Nocardia infection were identified by retro...

Nocardiosis is an opportunistic infection in patients with depressed cell-mediated immunity. Inhalation is the primary route for exposure via dust particles. Patients with acquired immune deficiency syndrome (AIDS) are at increased risk of disseminated disease. A challenge in the diagnosis of pulmonary nocardiosis is that it can mimic other pulmonary diseases. Nocardia farcinica tends to be a m...

Nocardiosis is a rare but well-established opportunistic infection. We are presenting two cases of Nocardiosis diagnosed in the microbiology laboratory, one in an immuno-competent elderly patient and the other in a immunocompromised patient with AIDS. The first case was of pulmonary Nocardiosis which was caused by the Nocardia asteroides complex and concomitant infections with Staphylococcus au...

A case of pulmonary nocardiosis is reported in a patient with malignant lymphoma and hypoimmunoglobuliwmia. The nocardiosis initially appeared as a dense infiltration in the right qper lobe, subsequently as bilateral long infiltrations. Nocardia asteroides was found in infralaryngeal secretion obtained by transtracheal aspiration. Treatment with sulfadine, lrimethoprim, and sulfamethoxazole (Se...

Pulmonary nocardiosis is a rare disease, which mainly affects immunocompromised hosts such as uncontrolled diabetics; HIV patients; and patients on immunosuppressive therapies such as anticancer drugs, systemic steroids, and transplant recipients. The diagnosis is often missed and delayed, resulting in inappropriate treatment and thus higher mortality. We are reporting a case of pulmonary nocar...

A case of a localized testicular abscess due to Nocardia asteroides in a patient on immunosuppressive therapy for a myeloproliferative disorder is reported. Subsequent fatal dissemination of the infection to the prostate, lungs, and liver occurred. This represents the second reported case of nocardiosis of the testis. Extrapulmonary forms of nocardiosis must be recognized so that appropriate tr...
