Nocardia aurantiaca is a species of bacteria from the genus Nocardia that has been isolated from soil in Thailand. [1]
The rifamycins are a group of antibiotics that are synthesized either naturally by the bacterium Amycolatopsis rifamycinica or artificially. They are a subclass of the larger family of ansamycins. Rifamycins are particularly effective against mycobacteria, and are therefore used to treat tuberculosis, leprosy, and mycobacterium avium complex (MAC) infections.
Nocardiosis is an infectious disease affecting either the lungs or the whole body. It is due to infection by a bacterium of the genus Nocardia, most commonly Nocardia asteroides or Nocardia brasiliensis.
Nocardia is a genus of weakly staining Gram-positive, catalase-positive, rod-shaped bacteria. It forms partially acid-fast beaded branching filaments. It contains a total of 85 species. Some species are nonpathogenic, while others are responsible for nocardiosis. Nocardia species are found worldwide in soil rich in organic matter. In addition, they are oral microflora found in healthy gingiva, as well as periodontal pockets. Most Nocardia infections are acquired by inhalation of the bacteria or through traumatic introduction.
The Gemmatimonadota are a phylum of bacteria established in 2003. The phylum contains two classes Gemmatimonadetes and Longimicrobia.
Rebeccamycin (NSC 655649) is a weak topoisomerase I inhibitor isolated from Nocardia sp. It is structurally similar to staurosporine, but does not show any inhibitory activity against protein kinases. It shows significant antitumor properties in vitro (IC50=480nM against mouse B16 melanoma cells and IC50=500nM against P388 leukemia cells). It is an antineoplastic antibiotic and an intercalating agent.
Pseudomonas aurantiaca is an orange Gram-negative soil bacterium, originally isolated from the rhizosphere soil of potatoes. It produces di-2,4-diacetylfluoroglucylmethan, which is antibiotically active against Gram-positive organisms. It has shown potential for use as a biocontrol agent against plant-pathogenic microbes. Based on 16S rRNA analysis, P. aurantiaca has been placed in the P. chlororaphis group.
The Nocardiaceae are a family of aerobic, non-fastidious, high G+C, Gram-positive actinomycetes that are commonly found in soil and water. Members of this family have been isolated from Antarctic soils. Nocardiaceae present coccobacilli, filamentous or, rarely, fragmented and palisading forms, and filamentous species grow in a branching morphological pattern similar to fungal hyphae.
Nocardia veterana is a species of bacteria from the genus Nocardia that has been isolated from human bronchial lavage.
Amycolatopsis orientalis is a Gram-positive bacterium in the phylum Actinomycetota. It produces several substances with antimicrobial properties, including the antibiotic drug vancomycin.
Nocardia farcinica is a species of bacteria, once thought to be associated with farcy, and a member of the genus Nocardia. This species is very similar in phenotype to Nocardia asteroides, to the degree that some isolates of N. asteroides were later found to be Nocardia farcinica.
Nocardia ignorata is a species of bacteria and a member of the genus Nocardia. Its type strain is IMMIB R-1434T.
Amycolatopsis rifamycinica is a species of Gram-positive bacteria in the genus Amycolatopsis. It produces the rifamycin antibiotics, which are used to treat mycobacterial diseases such as tuberculosis and leprosy. The type strain of Amycolatopsis rifamycinica has been reclassified several times. When it was first isolated from a French soil sample in 1957, it was identified as Streptomyces mediterranei. In 1969, the species was renamed Nocardia mediterranei because its cell wall was thought to resemble that of Nocardia species. The species was renamed Amycolatopsis mediterranei in 1986 after finding that it is not susceptible to Nocardia phage and has a cell wall that lacks mycolic acid. Finally, in 2004, it was determined that strain DSM 46095 represented a new species, independent of Amycolatopsis mediterranei, based on 16S ribosomal RNA sequencing. The new species was named Amycolatopsis rifamycinica.
Nocardia alni is a species of bacteria from the genus Nocardia that has been isolated from the root nodules of Alnus glutinosa.
Streptomyces aurantiacus is a bacterium species from the genus Streptomyces which produces aurantin, pamamycin-621, aurantimycin A, aurantimycin B, aurantimycin C, aurantimycin D, dihydronancimycin and ancimycin.
Arcicella aurantiaca is a Gram-negative, strictly aerobic, vibrioid and non-motile bacterium from the genus of Arcicella which has been isolated from stream water in Kaohsiung in Taiwan.
Arsenicitalea aurantiaca is an arsenic-resistan bacteria from the family of Devosiaceae which has been isolated from high-arsenic sediments from the Jianghan Plain in China.
Prauserella rugosa is a bacterium from the genus Prauserella which has been isolated from the rumen of cattle.
Pseudonocardia aurantiaca is a Gram-positive and aerobic bacterium from the genus of Pseudonocardia which has been isolated from soil from Jianchuan in China.
Niabella aurantiaca is a Gram-negative, strictly aerobic and non-spore-forming bacterium from the genus of Niabella which has been isolated from greenhouse soil from Yeoju inn Korea.
Chitinophaga aurantiaca is a Gram-negative, rod-shaped, facultatively anaerobic and non-motile bacterium from the genus of Chitinophaga.
