Pulmonary nocardiosis (PN) is an infrequent and severe infection due to Nocardia spp., which may behave as both opportunistic and primary pathogens. The presentation of a Nocardia infection is quite variable. We report a case of pulmonary nocardiosis in an immunocompetent 24-year-old female, who was initially treated with meropenem without response. A chest radiograph revealed bilateral irregul...

BACKGROUND Pulmonary nocardiosis mimic pulmonary tuberculosis in most clinical and radiological manifestations. In Tanzania, where tuberculosis is one of the major public health threat clinical impact of nocardiosis as the cause of the human disease remains unknown. The objective of the present study was to isolate and identify Nocardia isolates recovered from TB suspects in Northeastern, Tanza...

An 86-year-old woman with a 6-year history of bronchiectasis and recurrent pneumonia in the right lung presented to our hospital several weeks' bloody sputum. Imaging studies showed ground-glass infiltrative opacities lung, Nocardia species were repeatedly isolated on sputum culture testing. Genetic testing identified wallacei, which was resistant sulfamethoxazole/trimethoprim. Therefore, patie...

Nocardiosis is an infrequent but serious pulmonary infection caused by Gram-positive aerobic actinomycetes. In this paper, we report on a 48-year-old patient with pleuropulmonary nocardiosis and cirrhosis due to chronic hepatitis C virus infection treated with triple antiviral treatment complicated by prolonged neutropenia.

Nocardiosis is an extremely rare infection, which usually happens in immunocompromised hosts. Here we report a case with muscular and pulmonary infection of Nocardia in a membranous glomerulonephritis patient only treated with steroids for immunosuppression. This case revealed an uncommon Nocardia infection site, and a disseminated Nocardiosis occurs in a mild immunosuppressed patient.

The reported case is of primary pulmonary nocardiosis, caused by Nocardia brasiliensis, in a immunocompromised patient, which ended fatally despite appropriate treatment. The partially acid fast filamentous bacterium was predominant on direct examination of the sputum. It was cultured on blood agar, MacConkey agar and by paraffin baiting technique. The bacterium was resistant to cotrimoxazole, ...

Pulmonary nocardiosis (PN) is an infrequent and severe infection due to Nocardia spp. It is more common in immunosuppressed individual. The aim of this study was to evaluate the clinical features, evolution and prognosis of PN in immuno-competent hosts. The study group comprised 4 consecutive immuno-competent patients with pulmonary nocardiosis acquired in a community setting, diagnosed and fol...

Nocardiosis is a localized or disseminated infection caused by gram-positive bacteria of the genus Nocardia. The infection most commonly affects the lungs, skin and central nervous system. Nocardiosis principally occurs in individuals with cellular immunodeficiency and should be considered in the differential diagnosis when such individuals present respiratory, cutaneous or neurological alterat...

We report a case of pulmonary nocardiosis in a 41-year-old asthma patient. Chest radiographs showed bilateral air space and consolidations.Acid-fast branching filaments were demonstrated in sputum, and the grown organism was identified phenotypically and confirmed using16S rDNA sequencing (accession no. KX500116). The patient received a combination of medical treatments, but developed complicat...

Nocardiosis is an opportunistic infection caused by the Gram-positive weakly acid-fast, filamentous aerobic Actinomycetes. The lungs are the primary site of infection mainly affecting immunocompromised patients. In rare circumstances even immunocompetent hosts may also develop infection. Diagnosis of pulmonary nocardiosis is usually delayed due to nonspecific clinical and radiological presentat...
