BACKGROUND: Nocardiosis is a rare disease with polymorphic presentations. Epidemiology and clinical presentation could change with the increasing number of immunocompromised patients. METHODS: Medical records and microbiologic data for patients affected by nocardiosis and treated in the university hospital of Marseille between 2004 and 2014 were retrospectively analyzed. RESULTS: We analyzed 34 patients infected by Nocardia spp during this period...

An overview on the microbial sterol catabolism is described with a focus on the catabolic step of the 3β-hydroxy-5-en structure. Cholesterol oxidase transforms this structure into the corresponding 3-keto-4-en feature, and thus initiates the sterol molecule catabolism. The oxidase has been found in a large number of microorganisms, especially in actinobacteria as species of Rhodococcus and Streptomyces Other actinobacteria as species of Mycobacterium and Nocardia possess NAD(P)-dependent dehydrogenase for this catabolic step...

Mycobacteria are endowed with a highly impermeable mycomembrane that confers intrinsic resistance to many antibiotics. Several unique mycomembrane glycolipids have been isolated and structurally characterized, but the underlying organization and dynamics of glycolipids within the cell envelope remain poorly understood. We report here a study of mycomembrane dynamics that was enabled by trehalose-fluorophore conjugates capable of labeling trehalose glycolipids in live actinomycetes. We identified fluorescein-trehalose analogs that are metabolically incorporated into the trehalose mycolates of representative Mycobacterium, Corynebacterium, Nocardia and Rhodococcus species...

A rubber-degrading bacterial consortium named H2DA was obtained from an enrichment culture with natural rubber latex and rubber-processing factory waste in Vietnam. Gel permeation chromatography analysis revealed that only the strain NVL3 degraded synthetic poly(cis-1,4-isoprene) into low-molecular-weight intermediates among the three strains found in the H2DA. The 16S-rRNA gene sequence of NVL3 showed the highest identity with that of Nocardia farcinica DSM 43665(T). NVL3 accumulated aldehyde intermediates from synthetic poly(cis-1,4-isoprene) on a rubber-overlay plate as indicated by Schiff's staining...

A 72-year-old man with a history of blastoid variant stage IV relapsed refractory mantle cell lymphoma presented with new central nervous system (CNS) symptoms. Brain imaging was positive for rim-enhancing lesions along with a mitral valve mass on the echocardiogram. It was a challenge to establish the exact aetiology of these lesions in this patient. He was empirically treated with chemotherapy on the presumption that the brain lesions were secondary to progressive malignancy. However, brain biopsy was negative for malignancy and blood cultures were found positive for Nocardia kroppenstedtii sp nov...

Tuberculosis (TB) is one of the most common zoonotic infectious diseases in the world. Identification of Mycobacterium isolates is essential for proper treatment of TB. The aim of this study was to identify Mycobacterium isolates collected from TB patients in Alborz Province, Iran, by region of differentiation (RD)-typing. Fifty samples from tuberculosis patients were cultured in pyruvate and glycerinated Lowenstein-Jensen medium. DNA was extracted from the isolates by the van Solingen method and subjected to polymerase chain reaction (PCR)-16SrRNA, PCR-IS6110, and RD-typing with primers RD1, RD4, RD9, and RD12, respectively...

Despite the development in the identification of Nocardia spp., common challenges exist in the laboratory diagnosis and management of nocardiosis. We report two cases of disseminated nocardiosis in a patient with hematologic disorder and in a patient with systemic lupus erythematosus, where the cooperation between various specialists was essential to set up the adequate diagnosis of disseminated nocardiosis.

OBJECTIVES: The aims of this study were to explore the clinical distribution, by species, of the genus Nocardia and to assess the antimicrobial susceptibilities of the 10 most prevalent species identified in Spain. METHODS: Over a 10 year period (2005-14), 1119 Nocardia strains were molecularly identified and subjected to the Etest. The distribution and resistance trends over the sub-periods 2005-09 and 2010-14 were also examined. RESULTS: Of the strains examined, 82...

The bacterium Nocardia terpenica IFM 0406 is known as the producer of the immunosuppressant brasilicardin A. Here, we report the completely sequenced genome of strain IFM 0406, which facilitates the heterologous expression of the brasilicardin biosynthetic gene cluster but also unveils the intriguing biosynthetic capacity of the strain to produce secondary metabolites.

Differentiation of Tsukamurella from the other related genera, such as Nocardia, Rhodococcus, and Gordonia; and species identification within these genera has been difficult in most clinical microbiology laboratories, as they share similar phenotypic properties.

The marine sponge-derived actinomycete, strain ST01-07T, was isolated from Xestospongia sp. collected from the Andaman Sea. The strain was characterised taxonomically by polyphasic approach. The strain contained meso-diaminopimelic acid in the peptidoglycan, whole cell sugars were arabinose, galactose, glucose, mannose, and ribose. Mycolic acids that co-migrated with those from the type strain of Nocardia araoensis NBRC 100135T were observed in whole cell extract. MK-8(H4-cycl) was the predominant menaquinone...

BACKGROUND: Nocardia is an opportunistic pathogen that can cause life-threatening disease. We aimed to characterize the epidemiological, microbiological, and clinical features of nocardiosis in the tropical north of Australia. METHODS: We conducted a retrospective cohort study of nocardiosis diagnosed between 1997 and 2014. Population-based incidences were calculated using district population data. RESULTS: Clinically significant nocardiosis was identified in 61 patients...

BACKGROUND: Nocardia is a genus of gram-positive Actinomycetes that are ubiquitous in decaying organic material, soil, and water. Some Nocardia species can infect humans, mainly by airborne transmission. Several reports describe disseminated infections, which are rare and mostly affect strongly immunocompromised patients because intact T-cell-mediated immunity is the major protective mechanism. CASE REPORT: We report a case of disseminated pulmonary, cerebral, and cutaneous infection with Nocardia farcinica in a 66-year-old kidney transplant recipient treated with low-dose triple immunosuppression...

Many toxic insecticides used worldwide as well as some chemical warfare agents are phosphotriester derivatives. Therefore, detoxification of organophosphorus compounds has become the subject of many studies and in particular bioremediation, based on the phosphotriesterase catalysed hydrolysis of these compounds, has shown to be an effective and ecological methodology. In order to identify new bacterial phosphotriesterases, a simple and sensitive fluorimetric screening method on solid media was employed that allowed the selection of six strains with phosphotriesterase activity...

Bacterial mycetoma is a neglected disease mainly observed in tropical area countries and typically associated with rural conditions, making its presence in developed countries of temperate climate areas rare. However, we report the first case of an autochthonous mycetoma case in continental France that originated from a new Nocardia species. A Gram-positive filamentous bacterium (OFN 14.177(T)) was isolated from a pus sample from the mycetoma of a male French patient 92 years old suffering from chronic lymphocytic leukemia...

Nocardiosis is a rare cause of opportunistic infection post hematopoietic stem cell transplant (HSCT) occurring in about 0.3% of patients. The risk factors include delayed immune reconstitution, prolonged neutropenia, and graft-versus-host disease. The most common site of infection is the lung, followed by the brain and the skin. Concomitant pulmonary and central nervous system (CNS) nocardiosis is an extremely rare entity as presented in our case. We present the case of a 72-year-old male at 137 days post transplant presenting with complaints of headache and slurred speech...
