Proposal of a new genus, Gordona, for slightly acid-fast organisms occurring in sputa of patients with pulmonary disease and in soil.

    Journal of general microbiology
  • 1 September 1971
TLDR
The genus Gordona shows characters intermediate between the genera Mycobacterium and Nocardia, and can be isolated from sputa of patients with lung cavities or bronchiectasis and from soil by prior treatment with alkali.
Studies on the epidemiology of nontuberculous mycobacteriosis in Japan.
The epidemiology of mycobacterial disease in Japan changed considerably over the period 1971 to 1984. During this time, the incidence of pulmonary disease caused by Mycobacterium tuberculosis has
Cefotaxime-resistant Nocardia asteroides strains are isolates of the controversial species Nocardia farcinica
TLDR
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.
Therapeutic effect of a new antibacterial substance ofloxacin (DL8280) on pulmonary tuberculosis.
TLDR
A new antibacterial substance, ofloxacin (DL8280), was used in the treatment of pulmonary tuberculosis as single doses of 300 mg daily for 6 to 8 months, and resistance of tubercle bacilli to the agent appeared in patients who did not show negative conversion.
Human disease due to Mycobacterium smegmatis.
TLDR
The similarity of M. smegmatis to M. fortuitum and the failure to recognize that the former is an environmental species may have contributed to previous failures to recognize it as a human pathogen.
Lung Infection Caused by Gordona aurantiaca (Rhodococcus aurantiacus)
TLDR
It is reported that Gordona aurantiaca (Rhodococcus Aurantiacus) caused a lung infection in humans and a 50-year-old male farmer is shown, the first report of infection by this organism.
Clinical and laboratory features of Nocardia nova
TLDR
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.
Identification of mycobacteria.
TLDR
An identification system for the genus Mycobacterium is presented, based on data from 637 strains, and the total number of characteristics used for identification is 59, as 12 characteristics are used in two tables.
A co-operative numerical analysis of rapidly growing mycobacteria.
TLDR
All nine major clusters defined in the study were of named species; however, three of these were noted to contain two or more species and the reduction of some of these to synonymy with prior epithets is discussed.
Adansonian classification of mycobacteria.
  • M. Tsukamura
  • Biology, Medicine
    Journal of general microbiology
  • 1 November 1966
TLDR
Mycobacterium aurum is a new species consisting of rapidly growing scoto-chromogenic mycobacteria with urease, nicotinamidase and pyrazina-midase and some strains also with acetamidases and allantoinase.
