The first isolation of Nocardia
nova from an HIV-1 infected individual in Japan.
A) Cepa 1-4c (Sphingomonas sp.) inhibicion, B) cepa 1-7c (Sinorhizobium sp.) antagonista 50-50, C) cepa 2-7a (Nocardia
cerradoensis) Sumamente positiva y la cepa 2-10bp (Burkholderia phytofirmans) antagonista 50-50.
Kinyoun stain was 100% sensitive and specific for Nocardia
 has done the same process of isolation of the endophytic Actinomycetes from roots, stems, and leaves of herbaceous and woody plants in the sterile environment of Chiang Mai, Thailand, where the largest group of isolates they found were Microbispora sp, Streptomyces, Nocardia
, and Micromonospora.
Accurate identification of Nocardia
species is burdened by its characteristic branching on Gram staining, which makes it seem acid fast and mimics Mycobacterium tuberculosis.

Cultures grew variable branching filamentous bacteria after 3 days of incubation, later identified as Nocardia
pseudobrasiliensis using high-performance liquid chromatography (HPLC method done in Quest Diagnostics Infectious Diseases, a reference laboratory in California).
There was no evidence of malignancy, but multiple filamentous bacteria consistent with the Nocardia
species were identified.
(41%), followed by staphylococci (11%), Burkholderia cepacia (7%), and Nocardia
The genus Nocardia
is a group of environmental bacteria that usually manifest as an opportunistic infection in immunocompromised hosts.
(3,4) Other pathogens known to cause concretions on the lacrimal canaliculus include, Candida albicans, Aspergillus niger, Fusobacterium species, and Nocardia
In particular, several species belonging to Nocardia
, Mycobacterium, and Rhodococcus have been identified (61,62).
(1) The most common organisms involved in the development of this condition include the fungus Madurella mycetomatis and the Actinomycetes Nocardia
Brasieliensis, Actinomadura madurae and Actinomadura pelletieri.
Based on morphological, biochemical and microscopic observations, these isolates were assigned to four genera (data not shown)--Streptomyces (26 no.), Nocardia
(12), Micromonospora (1) and Saccharopolyspora (2).
There were 42 dominant actinobacteria species belonging to 10 genera, in which Nocardiopsis, Kribbella, Nocardia
, Arthrobacter and Umezawaea were not reported in previous research (Gonzalez et al., 2005).
