The clinical appearance of infection due to Nocardia spp. varies widely. The low sensitivity of direct microscopy and the slow growth of the organism challenge the laboratory diagnosis. We present the case of a skin abscess in an immunocompetent man caused by Nocardia brasiliensis. Diagnosis was made by cultivation and 16S rRNA sequencing. Using indirect immunofluorescence and Western blot, a s...

INTRODUCTION We present 4 local cases of nocardiosis in HIV-infected patients and discuss the diagnosis, clinical syndromes and therapy of nocardiosis. CLINICAL PICTURE Two cases presented with pulmonary nocardiosis, one had a cervical lymph node abscess and one had disseminated nocardiosis with pulmonary, cerebral and soft tissue involvement. TREATMENT Combination therapy is often employed...

Pulmonary nocardiosis is commonly recognized as an opportunistic infection in patients with predisposing immunosuppressive conditions. However, reports of pulmonary nocardiosis in the immunocompetent host are rare. Here, we report a case series of four patients with pulmonary nocardiosis without a predisposing condition.

Pulmonary nocardiosis is an infrequent and severe infection due to Nocardia species, microorganisms that may behave both as opportunists and as primary pathogens. Diagnosis of pulmonary nocardiosis is frequently delayed and a high level of suspicion is required in patients with underlying diseases or chronic corticosteroid therapy. Hereby we are presenting a case of pulmonary nocardiosis mimick...

BACKGROUND AND PURPOSE Nocardia is an uncommon pathogen in humans, and most patients with nocardiosis are immunocompromised, with variable etiologies. To understand the incidence, clinical characteristics, treatment and outcome of pulmonary and bloodstream nocardiosis, we conducted a retrospective study in two tertiary care hospitals in northern Taiwan. METHODS We reviewed laboratory culture ...

Disseminated nocardiosis is a well-described infection occurring in immunosuppressed individuals. Of the several species of Nocardia, Nocardia farcinica is being increasingly recognized as a pathogen capable of causing severe systemic disease. Described here is a case of disseminated nocardiosis with involvement of the brain, eyes, lymph nodes, and lung with biopsy-proven N. farcinica, with a d...

Nocardiosis is a rare infection that in more frequent in patients with systemic lupus Erythematosus and its clinical manifestations are nonspecific.while concurrent treatment by corticosteroids is an independent risk factor for nocardiosis it increases both diagnostic and mangement problems.this article presents a 35 years old woman who has systemic lupus Erythematosus.she was hospitalized due ...
