Granulomatous infections are commonly associated with mycobacteria, brucellosis, actinomycosis, nocardiosis, spirochetes, and fungi. Rarely, granuloma formation is a host response to other bacterial infection. Osteomyelitis and osteitis that reactivate many years after the primary episode is a known phenomenon. A reactivation that presents as a granulomatous disease is rare. We present a case o...

Nocardiosis is often misdiagnosed as tuberculosis in patients with HIV, as both diseases have similar manifestations. We describe the successful management of a case of advanced AIDS with disseminated Nocardial infection due to N. asteroides. Nocardial infection needs to be suspected in a patient with HIV infection when there is chest radiographic abnormality and when thrice sputum microscopy f...

The organism responsible for endocarditis of a prosthetic aortic valve was identified as Nocardia asteroides. The patient was treated with intravenous amikacin (250 mg four times a day) and intravenous imipenem (1.5 g four times a day). The valve was replaced under this new antibiotic regimen. This is the first report of survival after prosthetic valve nocardiosis.

Nocardial brain abscesses remain a clinical challenge. We successfully treated a patient with nocardial brain abscess, mycetoma, pneumonia, and glomerulonephritis. Nocardial soft tissue involvement, mycetoma, is well known. However, the fact that actinomycetoma can metastasize may not be as well appreciated. The association between nocardiosis and glomerulonephritis should be better clarified.

We read with interest the article on pulmonary nocardiosis in southern Taiwan by Chen et al. In their study, eight of the 20 patients with pulmonary nocardiosis had pleural effusion and three of these patients had empyema thoraces. Among these three nocardial empyema cases, the authors reported a 61-year-old man with diabetes mellitus and chronic liver disease suffering from an acute course of ...

Nocardiosis is a rare cause of opportunistic infection post hematopoietic stem cell transplant (HSCT) occurring in about 0.3% of patients. The risk factors include delayed immune reconstitution, prolonged neutropenia, and graft-versus-host disease. The most common site of infection is the lung, followed by the brain and the skin. Concomitant pulmonary and central nervous system (CNS) nocardiosi...

TOPIC: Chest Infections TYPE: Fellow Case Reports INTRODUCTION: Pulmonary nocardiosis is an uncommon disease with a diverse range of radiographic appearances. We report interesting case pulmonary in renal transplant patient presenting as dense, rapidly enlarging anterior lung mass invasion into the chest wall. CASE PRESENTATION: Our 41-year-old male history autosomal dominant polycystic kidney ...

ObjectiveTo analyse relevant changes in incidence, clinical and microbiological characteristics of nocardiosis over the last 24 years at current institution.Materials methodsThe records patients with (2006–2018) were reviewed then compared a previous cohort (1995–2006). Nocardia isolates identified by 5’-end-16S-rRNA-gene-PCR targeting first 500 bp gene sequencing. Susceptibility tests determin...

Nocardia are gram-positive and partially acid-fast bacteria with saprophytic lives in the environment. These groups of bacteria are able to enter the human body through traumatic inhalation and may consequently cause Nocardiosis infections. Case Presentation: A 32-year-old man was referred to Al-Zahra Hospital with symptoms such as fever, gradual weight loss, and persistent coughing. First, th...
