In 2008, three clinical isolates (W9405(T), W9409 and W9575) were obtained from bronchial wash or sputum specimens from patients from the state of Arizona and characterised by polyphasic analysis. All three clinical isolates 16S rRNA gene sequences were found to be 100% identical to each other and showed the strains belong in the genus Nocardia. BLASTn searches in the GenBank database of near full-length 16S rRNA gene sequences showed the highest sequence similarities to the type strains of Nocardia takedensis (98.

Nocardia species are ubiquitous in the environment with an increasing number of species isolated from clinical sources. From 2005 to 2009, eight isolates (W9042, W9247, W9290, W9319, W9846, W9851T, W9865, and W9908) were obtained from eight patients from three states in the United States and Canada; all were from males ranging in age from 47 to 81 years old; and all were obtained from finger (n = 5) or leg (n = 3) wounds. Isolates were characterized by polyphasic analysis using molecular, phenotypic, morphologic and chemotaxonomic methods.

The mutant prevention concentration (MPC) for ciprofloxacin was determined for two Rhodococcus equi strains. The MPC for both strains was 32 mug/ml, which is above the peak serum concentration of ciprofloxacin obtainable by oral administration in humans. Nine single nucleotide changes corresponding to eight amino acid substitutions in the quinolone resistance-determining regions of DNA gyrase subunits A and B were characterized.

Members of the genus Nocardia are responsible for cutaneous, pulmonary and disseminated human infections. From 2003 to 2008, four nocardioform strains (W8027, W8681, W9071 and W9241(T)) were isolated from patients in the state of Florida, USA. Ribosomal gene sequencing analysis suggested that a novel species of the genus Nocardia had been isolated.

Four nocardioform bacterial strains isolated from clinical respiratory sources were characterized using a polyphasic taxonomic approach. On the basis of 16S rRNA gene sequence analyses, these strains were found to be 100 % similar to each other and were shown to belong to the genus Nocardia. Chemotaxonomic data [major menaquinone: ω-cyclic isoprene side chain MK-8(H₄(cycl)); major polar lipids: diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol and phosphatidylinositol mannosides; major fatty acids: monounsaturated fatty acids with a considerable amount of tuberculostearic acid; and mycolic acids (52-62 carbon atoms)] were consistent with the assignment of the novel strains to the genus Nocardia.

Comparative sequence analysis showed that genetic diversity was generated in the coding region of this gene by both tandem repeats and point mutations. Each unique sequence in an outbreak cluster was assigned an arbitrary number or CSP sequence type.
