[1] Formerly known as Pseudomonas testosteroni, this bacillus was reclassified with molecular methods in 1987 and renamed as Comamonas testosteroni as it is known to use testosterone as the solely carbon source to grow. (imjsu.org)
After the biochemical identification tests and the use of VITEK-2 Compact (Biomerieux, France) automated microbial identification system, pathogenic bacteria was identified as Comamonas testosteroni . (imjsu.org)
There has been an increase in bacterial infections caused by Comamonas testosteroni and antibiotic resistance of the bacteria. (imjsu.org)
The intention of this study was to identify the bacterial pathogens infecting Oreochromis niloticus (Nile tilapia) and Clarias gariepinus (African catfish), and to establish the antibiotic susceptibility of fish bacteria in Uganda. (e-fas.org)
This observed resistance is most probably intrinsic to those bacteria, suggesting minimal levels of acquired antibiotic resistance in fish bacteria from the study area. (e-fas.org)
Antibiotic1

Degradation3
3,17β-Hydroxysteroid dehydrogenase (3,17β-HSD) from C. testosteroni is a Testosterone -inducible protein and a key enzyme in steroid degradation. (idexlab.com)
In this study, using Comamonas testosteroni as a model organism, we demonstrated the involvement of Comamonas biofilms in denitrification under bulk aerobic conditions and elucidated the influence of nitrate respiration on its biofilm lifestyle. (ntu.edu.sg)
Under bulk aerobic condition, biofilms of C. testosteroni were capable of reducing nitrate, and intriguingly, nitrate reduction significantly enhanced viability of the biofilm-cells and reduced cell detachment from the biofilms. (ntu.edu.sg)
Taking these factors together, this study reveals that nitrate reduction occurs in mature biofilms of C. testosteroni under bulk aerobic conditions, and the respiratory reduction of nitrate is beneficial to the biofilm lifestyle by providing more metabolic energy to maintain high viability and a higher level of c-di-GMP to reduce cell detachment. (ntu.edu.sg)
Using samples collected from the Sooke, Nanaimo, and Cowichan Rivers on Vancouver Island, British Columbia, we show that the E. muelleri microbiome is distinct from the ambient water and adjacent biofilms and is dominated by Sediminibacterium, Comamonas , and unclassified Rhodospirillales. (nature.com)
In addition, no study has yet determined if freshwater sponge microbiomes differ from adjacent biofilms. (nature.com)
Our study clearly demonstrates that the resistance profile varies in community-based intra-abdominal infections. (turkishjournalpediatrics.org)
Plasmid1
However, whereas pK2.4-EGFP-4 could integrate into the chromosomal DNA of C. testosteroni and knock out the βhsd gene promoter, pBB2.4-EGFP-8 could replicate in C. testosteroni cells as a free plasmid DNA. (idexlab.com)
Microbial1
These studies have found that, like marine sponges, freshwater sponges are primarily populated by Proteobacteria, Bacteroidetes, and Actinobacteria, though the resident microbial communities still differ substantially from those of marine sponges [ 5 ]. (nature.com)

Elucidating the mechanism of 3,17β-HSD gene (βhsd) regulation may help us to generate prospective C. testosteroni mutants for bioremediation. (idexlab.com)
Two potential promoters and two repeat sequences (RS, 16 bp), spaced to each other by 1661 bp, were also found upstream of the βhsd gene C. testosteroni. (idexlab.com)
In addition, a brp gene knock-out mutant of C. testosteroni was prepared. (idexlab.com)
These knock-out mutants showed an enhanced expression of both the βhsd gene and the hsdA gene (the latter coding for 3α-HSD/CR) in the presence of Testosterone . (idexlab.com)
Our data reveal that the βhsd gene undergoes complex regulation involving the two promoters, a loop structure via the two repeat sequences, and the steroid Testosterone . (idexlab.com)
Environments2
Comamonas testosteroni is a gram-negative bacillus which commonly occurs in various environments worldwide. (imjsu.org)
