Cell extracts prepared by ultrasonic disruption of 17 strains of the 'rhodochrous' complex and related taxa were compared by polyacrylamide gel electrophoresis and for immunologic relatedness, by skin test reactions. Two organisms, Jensenia canicruria and Nocardia calcarea, gave similar gel patterns and skin test reactions, and are considered to be identical. Extracts of nocardia rubra showed a...
Kwapinski, J. B. (University of New England, Armidale, N.S.W., Australia). Antigenic structure of Actinomycetales. VI. Serological relationships between antigenic fractions of Actinomyces and Nocardia. J. Bacteriol. 86:179-186. 1963.-A total of 52 chemical fractions were obtained by a comprehensive technique of preparation from three strains of Actinomyces and three strains of Nocardia. The che...
AIM This study aims to describe the clinical features and management of Nocardia scleritis. METHODS The authors retrospectively reviewed medical charts of three patients with microbiologically proven Nocardia scleritis and reviewed literature. RESULTS All the patients presented with areas of well-demarcated, circumscribed abscess. No specific clinical feature could be attributed to the caus...
BACKGROUND Nocardia keratitis following surgical management of penetrating corneal injury is very rare. CASE A 38-year-old male presented with a deep stromal corneal infiltration with hypopyon of 10 days duration in his left eye. He had undergone a corneal tear repair on that eye 15 days prior to the onset of keratitis. The infiltrations were along the sutured corneal tear tracts. Before pres...
Pulmonary tuberculosis and pulmonary nocardiosis are similar in most clinical symptoms and radiological manifestation. In the developing countries like Egypt where tuberculosis is very common, anti-tuberculosis drugs are started on basis of radiology and clinical symptoms. This study included 600 sputum specimens collected from 200 patients diagnosed as pulmonary tuberculosis from three chest h...
Background. Risk factors for Nocardia infection in organ transplant recipients have not been formally assessed in the current era of transplantation. Methods. We performed a matched case-control study (1:2 ratio) between January 1995 and December 2005. Control subjects were matched for transplant type and timing. Univariate matched odds ratios were determined and conditional logistic regression...
Nocardia is a ubiquitous microorganism related to pyogranulomatous infection, which is difficult to treat in humans and animals. The occurrence of the disease is on the rise in many countries due to an increase in immunosuppressive diseases and treatments. This report of cases from Brazil presents the genotypic characterization and the antimicrobial susceptibility pattern using the disk-diffusi...
BACKGROUND Cystic fibrosis (CF) patients are predisposed to infection and colonization with different microbes. Some cause deterioration of lung functions, while others are colonizers without clear pathogenic effects. Our aim was to understand the effects of Nocardia species in sputum cultures on the course of lung disease in CF patients. MATERIAL AND METHODS A retrospective study analyzing t...
Nocardia species are ubiquitous in natural environments and can cause nocardiosis. Trimethoprim-sulfamethoxazole has long been the monotherapy treatment of choice, but resistance to this treatment has recently emerged. In this study, we used microplate Alamar Blue assays to determine the antimicrobial susceptibility patterns of 65 standard Nocardia isolates, including 28 type strains and 20 cli...
The properties of 42 strains of nocardoid (nocardioform) bacteria were compared. The results indicate that the organism previously called Nocardia turbata does not belong to the genus Nocardia nor does it fit into any of the previously described genera.
