We isolated five bacterial strains from patients diagnosed as having nocardiosis. Bacterial species were identified based on the similarities in the nucleotide sequences of 16S ribosomal RNAs. Three of the five strains were identified as Nocardia asteroids, but unexpectedly other two were Streptomyces hygroscopicus and Rothia dentocariosa. The latter two species are not members of the family No...
Identification of clinical isolates of Nocardia to the species level is important for defining the spectrum of disease produced by each species and for predicting antimicrobial susceptibility. We evaluated the usefulness of PCR amplification of a portion of the Nocardia 16S rRNA gene and subsequent restriction endonuclease analysis (REA) for species identification. Unique restriction fragment l...
Nocardia veterana is a recently characterized species within the genus Nocardia, and only three human clinical isolates have been reported for this species. We describe a case of ascitic fluid infection in an immunocompromised patient due to N. veterana. To our knowledge, this is the first report of a Nocardia sp. strain from ascitic fluid and the fourth report of N. veterana isolated from huma...
Introduction: In our Solar System the asteroid belt is compositionally zoned, with the asteroids similar in reflection spectrum to the carbonaceopus meteorites dominating the outer-half of the main belt. In the outer-half of the main belt about one-half of the carbonaceous asteroids are hydrous, based on their infrared spectra [1]. The asteroids in the inner-half of the main belt are predominan...
Background : Identification of Nocardia spp. in routine medical laboratories is based on phenotypic methods that is often time- consuming. The objective of this study was to diagnose Nocardia agents by PCR technique in BAL samples of patients with suspected tuberculosis admitted to hospitals in Tehran. Materials and Methods: In this study, 116 BAL samples of patients admitted in Baqiyatallah, I...
Nocardia spp. are rarely isolated in extrapulmonary clinical specimens. We describe the first case of olecranon bursitis caused by Nocardia asiatica. The patient, a traveler returning from Thailand, was successfully treated with linezolid.
Rifampin was glycosylated by a pathogenic species of Nocardia, i.e., Nocardia brasiliensis. The structures of two glycosylated compounds (RIP-1 and RIP-2) isolated from the culture broth of the bacterium were determined to be 3-formyl-23-(O-[beta-D-glucopyranosyl])rifamycin SV and 23-(O-[beta-D-glucopyranosyl])rifampin, respectively. Both compounds lacked antimicrobial activity against other gr...
Background & Aims: Nocardia asteroides is gram-positive, partially acid-fast, aerobic actinomycetes which cause a wide range of skin infections, and pulmonary, cerebral, and ocular infection. Case Presentation: A 60-year-old man with diabetes presented with ocular ulcers in 2015. Through the medical records evaluation, physical examination, and biochemical evaluation of the patient, Nocardia as...
There are currently only a few thousand asteroids with known classifications. Our aim is to increase this number to over 20,000 by classifying asteroids identified in the Sloan Digital Sky Suvey (SDSS) Moving Object Catalogue using an artificial neural network that has been developed using the Neural Network Toolbox in Matlab. With this neural network, we are able to provide classifications for...
Pericarditis with hemodynamic compromise is a rare manifestation of infection with Nocardia asteroides. To our knowledge, only six cases have been reported previously. In contrast to other cases of pericardial disease due to Nocardia, culture of the pericardial fluid in our case was negative while culture of pericardial tissue led to the diagnosis. Surgical intervention and appropriate antibiot...
