Case Reports in Ophthalmology 2019To present a previously unreported cause of bacterial endophthalmitis manifesting as delayed post-traumatic endophthalmitis ultimately responsive to total capsulectomy.
PURPOSE
To present a previously unreported cause of bacterial endophthalmitis manifesting as delayed post-traumatic endophthalmitis ultimately responsive to total capsulectomy.
CASE REPORT
A patient presented with chronic endophthalmitis that occurred after ocular trauma with organic material and was eventually isolated. After a prolonged treatment course, including two pars plana vitrectomies and total capsulectomy, the patient achieved 20/80 visual acuity at 1-year follow-up.
CONCLUSION
This is the first reported patient with endophthalmitis due to , a Gram-positive bacillus found in soil that rarely causes human infection. The infection had a delayed presentation despite early prophylactic antibiotics and was ultimately eliminated with total capsulectomy. Removal of lens and lens capsule may be necessary in the management of post-traumatic endophthalmitis unresponsive to more conservative therapy, particularly in cases involving atypical organisms and lens capsule violation.

This work aims at functional studies of the multienzyme complexes produced by Oerskovia turbata JCM 3160 and reveal of their subunit structures. The multienzyme complexes were isolated, enzymatic assayed, the whole genome sequence was determined in fine scale, and the subunit structure was identified by Maldi-TOF mass spectrometry. The isolated multienzyme complexes here show similar particle size with the xylanosomes produced by Cellulosimicrobium cellulans F16, have at least two conserved multi-domain proteins, while differ significantly in enzymatic activities and low molecular weight subunit compositions. This is the first report of the enzymatic activities and subunit structures of xylanosome produced by Oerskovia turbata, providing insights into its diverse capability as well as degrading bias on hemicelluloses.

Oerskovia turbata is a yellow, motile actinomycete, which before now has only been found in soil and has not been known to cause disease in man or animals. It was isolated from 29 cultures of blood taken during 6 months from an urban pensioner after homograft replacement of his aortic valve. The combination of ampicillin, sulfamethoxazole, and trimethoprim was lethal for O. turbata in vitro; however, antimicrobial therapy alone failed to eradicate the patient's infection. Cure was achieved after the infected homograft was replaced with a prosthetic aortic valve. Although the source of O. turbata in this patient is unknown, sterilization of homograft valves with antimicrobial solutions is difficult. Moreover, environmental contamination during cardiopulmonary bypass is common. Oerskovia turbata is another opportunistic pathogen of man.

Here we report a case of acalculus cholecystitis, which presented with features of obstructive jaundice of one-week duration. The patient underwent cholecystectomy and bile grew a mixed culture of Oerskovia turbata and Myroides spp. Being a rare isolate, characteristic features of the former are described in this report. The patient recovered without any complication.

A case of Broviac catheter-related bacteremia in a 3-year-old boy infected with Oerskovia turbata is discussed. The blood cultures of the patient remained positive despite antibiotic therapy, and only with catheter removal was his blood sterilized. The microbiology and antimicrobial susceptibilities of this organism are described.

Re-evaluation of the status of the genus Oerskovia, reclassification of Promicromonospora enterophila (Jáger et al. 1983) as Oerskovia enterophila comb. nov. and description of Oerskovia jenensis sp. nov. and Oerskovia paurometabola sp. nov.
Phylogenetic analysis of Promicromonospora enterophila indicates that this taxon clusters with Cellulomonas species, adjacent to Cellulomonas turbata (basonym Oerskovia turbata). 16S rDNA analysis, DNA-DNA reassociation, riboprinting, peptidoglycan analysis and determination of phenotypic properties of various strains of P. enterophila and C turbata reveal that they form a cluster that can be distinguished unambiguously from other Cellulomonas species by morphology, amino acid composition of the cell wall and 16S rDNA signatures. As a result of thispolyphasic study, it appears taxonomically reasonable to re-establish the genus Oerskovia for C turbata and to reclassify P. enterophila as Oerskovia enterophila comb. nov.; two novel species, Oerskovia jenensis sp. nov. (type strain DSM 46000T = CIP 100330T) and Oerskovia paurometabola sp. nov. (type strain DSM 14281T = LMG 20385T), are also proposed.

The deoxynivalenol (DON)-degrading bacterium JB1-3-2 was isolated from a rhizosphere soil sample of cucumber collected from a greenhouse located in Zhenjiang, Eastern China. The JB1-3-2 strain is a Gram-stain-positive, nonmotile and round actinomycete. Growth was observed at temperatures between 15 and 40 ℃ (optimum, 35 ℃), in the presence of 15% (w/v) NaCl (optimum, 3%), and at pH 3 and 11 (optimum, 7). The major cellular fatty acids identified were anteiso-C, iso-C and anteiso-C. Genome sequencing revealed a genome size of 4.11 Mb and a DNA G + C content of 72.5 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the JB1-3-2 strain was most closely related to type strains of the Oerskovia species, with the highest sequence similarity to Oerskovia turbata NRRL B-8019 (98.2%), and shared 98.1% sequence identity with other valid type strains of this genus. Digital DNA‒DNA hybridization (dDDH) and average nucleotide identity (ANI) showed 21.8-22.2% and 77.2-77.3% relatedness, respectively, between JB1-3-2 and type strains of the genus Oerskovia. Based on genotypic, phylogenetic, chemotaxonomic, physiological and biochemical characterization, Oerskovia flava, a novel species in the genus Oerskovia, was proposed, and the type strain was JB1-3-2 (= CGMCC 1.18555 = JCM 35248). Additionally, this novel strain has a DON degradation ability that other species in the genus Oerskovia do not possess, and glutathione-S-transferase was speculated to be the key enzyme for strain JB1-3-2 to degrade DON.
