The medically important aerobic actinomycetes: epidemiology and microbiology
The epidemiology and microbiology of the major medically important aerobic actinomycetes, which have been a major source of interest for the commercial drug industry and have proved to be extremely useful microorganisms for producing novel antimicrobial agents, are reviewed.
New Nocardia taxon among isolates of Nocardia brasiliensis associated with invasive disease
Screening of invasive isolates of N. brasiliensis for susceptibility to ciprofloxacin will identify most isolate of the new taxon, which likely represents a new Nocardia species.

Obese children had similar estradiol levels and equivalent bone ages at a younger chronological age than nonobese children, and the role of leptin in both obesity and pubertal development is not directly correlated with the estradio level.
DNA amplification and restriction endonuclease analysis for differentiation of 12 species and taxa of Nocardia, including recognition of four new taxa within the Nocardia asteroides complex
These studies provide the first evidence for the separate identities of four antibiogram-defined (but currently unnamed) groups within the N. asteroides complex and the presence of two subgroups within N. transvalensis.
Cefotaxime-resistant Nocardia asteroides strains are isolates of the controversial species Nocardia farcinica
This work found the pattern of resistance to cefotaxime and cefamandole in 19% of 200 clinical N. asteroides isolates, the first recognition that N. farcinica has a specific drug resistance pattern and confirms the previously described concept that drug resistance patterns of N. Asteroides may be associated with specific taxonomic groups.
Comparison of species distribution and antimicrobial susceptibility of aerobic actinomycetes from clinical specimens.
Findings show that unusual species of aerobic actinomycetes can cause infection, colonization, or both and that antimicrobial resistance varies markedly by species.
Laboratory identification of Rothia dentocariosa and its occurrence in human clinical materials.
The importance of recognizing this organism is based on the fact that it is frequently isolated from human clinical materials and must be differentiated from morphologically similar organisms of the genera Actinomyces and Nocardia, which contain pathogenic members.

The strains studied were unique among nocardiae in having both alpha- and beta-esterase activity and the arylsulfatase activity at 14 days and antimicrobial susceptibility patterns, including susceptibility to erythromycin were the only routinely available methods that would separate N. nova strains from other members of N. asteroides.

These strains are the first described clinical isolates identified as B. casei, which was previously considered to be a nonpathogenic species.
