Nocardia cyriacigeorgica has recently been described as an "emerging" pathogen. However, DNA-DNA hybridization results confirm that Nocardia asteroides drug pattern type VI, which has long been recognized as a common and significant pathogen in the United States, belongs to the species N. cyriacigeorgica.

Nocardia spp. can lead to local or disseminated infections, especially in immunocompromised patients. Combination therapy of amikacin and imipenem is commonly used to treat severe nocardial infections. We describe a patient with imipenem-resistant Nocardia cyriacigeorgica, which, to our knowledge, has not been previously reported among isolates of this species.

Meteorites contain a record of impacts during all stages of asteroid origin and evolution: the formation and accretion of chondritic particles; the alteration, metamorphism and melting of asteroids; and the erosion and disruption of asteroids by hypervelocity impacts. A review of meteorite classification shows that numerous meteorites are not readily classified because they do not fit simple mo...

We report a detection of statistically significant color variations for a sample of 7,531 multiply observed asteroids that are listed in the Sloan Digital Sky Survey Moving Object Catalog. Using 5-band photometric observations accurate to ∼0.02 mag, we detect color variations in the range 0.06-0.11 mag (rms). These variations appear uncorrelated with asteroids physical characteristics such as d...

In this study, the hierarchical stability of the seven known large size ratio triple asteroids is investigated. The effect of the solar gravity and primary's J2 are considered. The force function is expanded in terms of mass ratios based on the Hill's approximation and the large size ratio property. The empirical stability parameters are used to examine the hierarchical stability of the triple ...

isfrared photometry at 1,2, 1.6, and 2.2pm (JHK) is reported 56 asteroids in the Em, Koronis and, Maria dynamiwd famij. These data are consistent with a simi!ar surface composition all of the asteroids of each family. The infrared CO1OS-S within :h family cluster in the region observed for the S taxonomic SS, but Em asteroids may belong to a separable K class. Aster243 Ida, which was observed b...

We report a female patient who repeatedly developed pancreatitis after trimethoprim-sulfamethoxazole (TMP/SMX) use. During childhood she had undergone an ureterosigmoidostomy after which she had been on TMP/SMX 480 mg daily as prophylaxis for pyelonephritis for many years. The patient presented with abdominal pain caused by acute pancreatitis. No other cause, except for TMP/SMX use, could be id...

Nocardiosis is an extremely rare infection, which usually happens in immunocompromised hosts. Here we report a case with muscular and pulmonary infection of Nocardia in a membranous glomerulonephritis patient only treated with steroids for immunosuppression. This case revealed an uncommon Nocardia infection site, and a disseminated Nocardiosis occurs in a mild immunosuppressed patient.

A patient with severe non-healing microscopically proven Nocardia keratitis was treated with maximal topical amikacin followed by amniotic membrane transplantation (AMT) 2 months later (single-layer epithelial side-down). Epithelial healing was achieved, but neovascularization continued. This case report indicates that AMT combined with topical antibiotic provides pain relief and allows epithel...
