Background: Gordonia polyisoprenivorans is a ubiquitous aerobic actinomycetes bacterium that rarely cause infections in humans. Here, we report a case of G. polyisoprenivorans catheter-related bacteremia in an AIDS patient.
Case Presentation: A 37-year-old man with a past medical history of AIDS-related lymphoma suffered bacteremia caused by a Gram-positive corynebacterium. The strain was identified as a Gordonia species by matrix-assisted laser desorption ionization-time of flight mass spectrometry and confirmed to G. polyisoprenivorans by 16S rRNA combined with gyrB gene sequencing analyses. The patient was treated with imipenem and had a good outcome.
Conclusions: The findings from our case and previously reported cases indicate that malignant hematologic disease, immunosuppression, and indwelling catheter heighten the risk for G. polyisoprenivorans infection. Molecular methods should be employed for proper identification of G. polyisoprenivorans to the species level.

Article Synopsis
- * Over a 35-day period, these microbiomes achieved a remarkable 99% reduction of DEHP, with specific bacterial groups identified as key contributors to the degradation process.
- * In addition, certain bacterial strains, like Gordonia sp. and Gordonia polyisoprenivorans, were found to degrade DEHP by 65-97% within just 7 days, showing potential for broader application in addressing plastic pollution.

The intrinsic issue associated with the application of microbes for practical pollution remediation involves maintaining the expected activity of engaged strains or consortiums as effectively as that noted under laboratory conditions. Faced with various stress factors, degraders with dormancy ability are more likely to survive and exhibit degradation activity. In this study, a hydrocarbonoclastic and halotolerant strain, Gordonia polyisoprenivorans ZM27, was isolated via stimulation with resuscitation-promoting factor (Rpf).

The strain 135 is able to utilize a wide range of aromatic compounds. The aim of this work was to study the features of genetic organization and biotechnological potential of the strain 135 as a degrader of aromatic compounds. The study of the genome of the strain 135 and the pangenome of the species revealed that some genes, presumably involved in PAH catabolism, are atypical for and belong to the pangenome of .
