presence of fungal agents in lesions of two patients in tehran was studied. one of them had clinical symptoms of mycetoma in his foot, and the other had a skin infection in his arm. examination of the lesions indicated nocardia asteroides. these patients did not show any evidence of nocardia infection in other parts of the body. negative results were obtained from the cultures of blood and sputum.

Menaquinones were the only isoprenoid quinones found in 48 corynebacteria and actinomycete strains examined. Dihydromenaquinones having nine isoprene units were the main components isolated from Gordona, Mycobacterium, Corynebacterium bovis, Corynebacterium glutamicum and a strain labelled Nocardia farcinica, but dihydromenaquinones having eight isoprene units were characteristic of other Coryn...

Human nocardiosis may present as an acute or a chronic infection. Although a saprophyte Nocardia spp are responsible for superficial skin infections, pulmonary infections, and disseminated nocardiosis usually involving patients who are immunosuppressed and debilitated. Infections in immunocompetent individuals are usually chronic and present non-specific symptoms. Invasive and disseminated noca...

We report a case of endogenous Nocardia endophthalmitis in a patient with systemic lupus erythematosus (SLE). He developed a parafoveal lesion in the right fundus while on systemic corticosteroid and antibiotic treatment. Initially we suspected a fungal origin and treated him with antifungal drugs. The intraocular disease progressed without improvement and advanced to the vitreous cavity. Nocar...

Sixteen strains designated Mycobacterium farcinogenes, fifteen Mycobacterium senegalense, and ten Nocardia farcinica were, together with strains of Mycobacterium and Nocardia, subjected to numerical phenetic analyses using 96 unit characters. The data were examined using the simple matching (SSM), Jaccard (SJ) and pattern (DP) coefficients and clustering achieved using the unweighted average li...

Nocardiosis is an uncommon infection caused by the aerobic actinomycete nocardia. Identification of the pathogen is essential for the definitive diagnosis and for an effective treatment. This report describes a case of chronic granulomatous pleuritis caused by nocardia. A 59 year old Japanese man had a history of repeated pyothorax. Right pleural decortication and thoracic drainage were perform...

The spectrum of infections with Nocardia spp. is heterogeneous. It has classically been associated with lung, brain, or skin involvement. We describe an unusual presentation of Nocardia asiatica (N. asiatica) in an Iraqi patient with myasthenia gravis suffering from a disseminated infection and presenting with an anterior mediastinal cystic mass. N. asiatica has only been three times described ...

A novel actinomycete strain YIM 33378T was isolated from a soil sample collected from Lijiang, Yunnan Province, China. Based on the results of phenotypic and genotypic characteristics, strain YIM 33378T should be assigned to a new species of the genus Nocardia, for which the name Nocardia lijiangensis sp. nov. is proposed. The type strain is YIM 33378T (= CCTCC AA 204005T = KCTC 19028T). The Ge...

We constructed a pair of Nocardia-Escherichia coli shuttle vectors, pNV18 and pNV19, by combining the mycobacterial plasmid pAL5000 with the E. coli vector pK18 or pK19. These vectors have a number of useful features, including small size (4.4 kb), a multiple cloning site, and blue/white selection. To our knowledge, pNV18 and pNV19 are the first cloning vectors for practical use in Nocardia spp.
