Nocardia is a gram positive, aerobic branched actinomycete; it is an ubiquitous soil saprophyte. As an infecting agent it has been increasingly identified in humans, especially in immuno-suppressed hosts. Nocardia as a cause of septic arthritis is very unusual. The described genus was Nocardia asteroides in nearly all previously reported cases. We report an unusual case of spontaneous Nocardia ...

Recent studies in the Parkinson's literature have cited a tuberculosis-like germ called Nocardia as being responsible for Parkinson's disease. Kohbata seemingly cemented a relationship between Nocardia and Parkinson's by finding serologic evidence in 20 of 20 Parkinson's patients, acknowledging that blood tests for Nocardia and the mycobacteria such as tuberculosis often cross-react, as they be...

Nocardia species are aerobic, gram-positive, filamentous, partially acid-fast actinomycetes which are found worldwide in soil and decaying organic plant matter. When they infect human beings, they generally enter through the respiratory tract and then disseminate systemically. Rarely has a primary infection occurred as the result of direct inoculation. Isolation of Nocardia from clinical specim...

purpose: to report 3 cases of nocardia keratitis following photorefractive keratectomy (prk). report of outbreak: four eyes of 3 patients (2 female and one male) who had undergone prk by a single surgeon at a single center developed nocardia keartitis 3 to 6 weeks postoperatively. mean age was 25 (range 23-28) years and mean onset of corneal manifestations was 29 (range 21-40) days after prk. c...

26 Antimicrobial susceptibility testing (AST) of clinical isolates of Nocardia is recommended to 27 detect resistance to commonly used antimicrobial agents; such testing is complicated by 28 difficulties in inoculum preparation and test interpretation. In this study, six laboratories 29 performed repetitive broth microdilution testing on single strains of Nocardia brasiliensis, 30 Nocardia cyri...

Recent reports of increasing in vitro sulfonamide resistance in Nocardia prompted us to investigate the findings. Despite the reports, there is a paucity of clinical reports of sulfonamide failure in treatment of nocardia disease. We reviewed 552 recent susceptibilities of clinical isolates of Nocardia from six major laboratories in the United States, and only 2% of the isolates were found to h...

Nocardia cyriacigeorgica is recognized as an emerging pathogen in many parts of the world. We present the first case description of invasive N. cyriacigeorgica pulmonary infection in the United States identified to the species level by 16S rRNA and hsp65 sequence analysis. A subsequent retrospective molecular screening of recent Nocardia clinical isolates at our New York City medical center yie...

INTRODUCTION The authors present IR spectra (0.9–2.5 μm) and narrowband photometry (3.0–3.5 μm) for low-albedo asteroids Ceres, Pallas, and Bamberga. The authors compare the major mineral absorption features to those found in primary carbonaceous chondrite matrix material (CCMM) and secondary alteration products. The observed differences between spectral reflectances between the three C-type as...

The cumulative effects of weak resonant and secular perturbations by the major planets produce chaotic behavior of asteroids on long timescales. Dynamical chaos is the dominant loss mechanism for asteroids with diameters D & 10 km in the current asteroid belt. In a numerical analysis of the long term evolution of test particles in the main asteroid belt region, we find that the dynamical loss h...
