BACKGROUND: Pulmonary nocardiosis is a rare but severe infection caused by Nocardia species. This study aimed at describing the clinical characteristics and prognosis of pulmonary nocardiosis. METHODS: An observational, retrospective study was undertaken of patients diagnosed with pulmonary nocardiosis over a 13-year period at the Kinki-Chuo Chest Medical Center, Osaka, Japan. RESULTS: Seven patients with airway nocardial colonization and 59 patients with pulmonary nocardiosis were identified, one of whom had disseminated nocardiosis...

A total of 118 actinobacterial isolates were collected from the three types of termite nests (mound, carton, and subterranean nests) to evaluate their potential as a source of bioactive actinobacteria with antimicrobial activity. The highest number (67 isolates) and generic abundance (7 known genera) of actinobacterial isolates were obtained from carton nests. Streptomyces was the dominant genus in each type of termite nest. In the non-Streptomyces group, Nocardia was the dominant genus detected in mound and carton nests, while Pseudonocardia was the dominant genus in subterranean nests...

To the best of our knowledge, no Chinese case studies concerning Nocardia infection have been published to date. Therefore, the present study aimed to retrospectively evaluate the risk factors, clinical features, imaging results, laboratory abnormalities, treatments and outcomes of nocardiosis in a Chinese tertiary hospital. Data collected from patients with laboratory-confirmed nocardiosis were retrospectively analyzed. A total of 40 patients who had a positive culture of Nocardia were included. The median time between the onset of symptoms and diagnosis was 42 days...

We herein report on a 69-year-old male who developed lung nocardiosis and brain abscessation. In April 2011, he was diagnosed as having systemic lupus erythematosus complicated by peripheral neuropathy. Immunosuppressive therapy with high-dose prednisolone was begun. In November 2011, he developed cryptococcal pneumonia and meningitis, which was treated with liposomal amphotericin and flucytosine for 4 weeks and was maintained with fluconazole. In April 2012, consolidation and peripheral atelectasis in the right middle lobe appeared...

Nocardia species are ubiquitous in the environment with an increasing number of species isolated from clinical sources. From 2005 to 2009, eight isolates (W9042, W9247, W9290, W9319, W9846, W9851T, W9865, and W9908) were obtained from eight patients from three states in the United States and Canada; all were from males ranging in age from 47 to 81 years old; and all were obtained from finger (n = 5) or leg (n = 3) wounds. Isolates were characterized by polyphasic analysis using molecular, phenotypic, morphologic and chemotaxonomic methods...

BACKGROUND: Infections caused by Nocardia farcinica are potentially lethal because of the organism's tendency to disseminate and resist antibiotics. Central nervous system involvement has been documented in 30% of infections caused N. farcinica. METHODS: Case report and review of the literature. RESULTS: A case of primary brain abscess caused by N. farcinica, identified by 16SrRNA sequencing, is presented, and 39 cases reported previously in the literature are reviewed...

Activated sludge plants (ASP) are associated with the stable foaming problem worldwide. Apart from the physical and chemical treatment methods, biological treatment method has been least explored and may prove to be a novel and ecofriendly approach to tackle the problem of stable foam formation. In ASP Nocardia species are commonly found and are one of the major causes for forming sticky and stable foam. This study describes the isolation and characterization of three Nocardia bacteriophages NOC1, NOC2, and NOC3 for the control of Nocardia species...

New methodologies were developed for the identification of Nocardia but the initial diagnosis still requires a fast and accurate method, mainly due to the similarity to Mycobacterium, both clinical and bacteriologically. Growth on Löwenstein-Jensen (LJ) medium, presence of acid-fast bacilli through Ziehl-Neelsen staining, and colony morphology can be confusing aspects between Nocardia and Mycobacterium. This study describes the occurrence of Nocardia spp. in a mycobacterial-reference laboratory, observing the main difficulties in differentiating Nocardia spp...

OBJECTIVES: To correlate the microbiological and clinical features of infections caused by Nocardia species. METHODS: We determined the species and drug susceptibility of 138 Nocardia strains isolated from 132 patients at the University of Texas M. D. Anderson Cancer Center (Houston, TX) from 2002 through 2012 and analyzed the clinical features. RESULTS: The 132 patients included 82 men and 50 women with a mean age of 59.1 years. All except two had underlying cancer, and 47 (35...
