A case of septic arthritis caused by N. asiatica is reported in a 72-year-old man with a history of chronic obstructive pulmonary disease and pneumoconiosis, who presented with subacute knee swelling following a recent episode of pneumonia.
Abstract
ABSTRACT Nocardia asiatica is a rare opportunistic pathogen typically associated with pulmonary and central nervous system infections; however, musculoskeletal infections are uncommon. We report a case of septic arthritis caused by N. asiatica in a 72-year-old man with a history of chronic obstructive pulmonary disease (COPD) and pneumoconiosis. The patient presented with subacute knee swelling following a recent episode of pneumonia. Gram staining of intraoperative synovial samples revealed branching filamentous organisms, and the isolate was identified as N. asiatica by mass spectrometry. Although the patient was transferred to another center during the initial phase of management, follow-up information obtained after discharge confirmed a favorable clinical recovery without recurrence. Our report contributes to the limited literature on the clinical manifestations, organ tropism, and antimicrobial susceptibility patterns associated with N. asiatica infection.
Abstract Introduction Nocardia is a rare group of opportunistic bacteria that normally causes infections in immunocompromised patients. It can involve multiple organ systems: most frequently the lungs, followed by the skin, central nervous system, bones, and joints. Within this group, Nocardia farcinica is among the mo...

A 77-year-old woman with a medical history of hypertension and diabetes presented with ulcerated purplish-red nodules on the lower extremities that had persisted for 3 months, and subsequent treatment with oral trimethoprim–sulfamethoxazole led to gradual regression of the lesions and scar formation.

Nocardiosis is an uncommon infection that presents as a chronic, debilitating illness with radiographic manifestations simulating lung cancer or tuberculosis. Immunocompromised hosts may develop a fulminant disease resembling acute bacterial pneumonia or disseminated disease. We report a case of a juvenile lupus who de...
Streptococcus intermedius is a gram-positive commensal associated with suppurative infections. Pediatric pulmonary abscesses due to S. intermedius are rare, and outcomes in children with severe neurological comorbidities are poorly characterized. A 5-year-old boy with refractory epilepsy and global developmental delay...
