Unlike other Kocuria species that are strictly aerobic, Kocuria kristinae is °C. The genus Micrococcus has been recently divided into Micrococcus, Kocuria. Kocuria is a genus of Gram positive bacteria in the phylum Actinobacteria, including the sequenced species Kocuria rhizophila. Kocuria has been identified in.

Indeed, the Port-A-Cath device might have provided a favorable niche for prolonged survival of the organism and subsequent recurrence. These bacteria have been identified as Kocuria species with the help of automated identification system and other molecular methods including 16S rRNA ribosomal ribonucleic acid evaluation.

Susceptibility towards bacitracin and lysozyme and resistance to nitrofurantoin, furazolidone and lysostaphin can be used to separate this bacterium from Staphylococci.

Emerging Bacterial Infection: Identification and Clinical Significance of Kocuria Species

Evaluation of a commercial microbial identification system based venus fatty acid profiles for rapid, accurate identification of plant pathogenic bacteria. Furthermore, there are no reports of biofilm production by Kocuria in the literature, yet it has been implicated in device-related bacteremia, implying that the colonization of Kocuria on a device will likely result in chronic recurrent bacteremia in a compromised host. Persistent bloodstream infection with Kocuria rhizophila related to a damaged central catheter.

S-Z Names validly published since 01 January Other categories and changes covered by the Rules Candidatus Some prokaryotic names without standing in nomenclature Other categories and changes not covered by the Rules Nomenclature Collections Miscellaneous. Kocuria flava Zhou et al.

This isolate was precisely identified and confirmed as K. A year-old man, a previously known case of diabetic nephropathy with end-stage renal disease undergoing continuous ambulatory peritoneal dialysis CAPD for the last four years, was admitted to kocurua tertiary-care hospital in Puducherry, with complaints of abdominal pain, pedal edema and loose stool for three days.

Kocuria salsicia Yun et al. Case Report A year-old female patient diagnosed with bipolar disease was admitted to the psychiatry department in Cairo University Hospital Kasr Al-Ainy. Misidentification among members of the Kocuria genus cannot be ruled out as other studies have reported such situations [ 513gemus ].

In the era of drug resistance, and prevalence of multi-drug resistant bacteria, occurrence of Kocuria spp in hospitalized patients should not always be ignored as contaminants. Appearance of Kocuria spp on blood agar after 24 hours of aerobic incubation. Received Jul 23; Accepted Aug Footnotes The authors have declared that no competing interests exist. Currently, there are more than 18 species of Kocuria identified based on the 16S rRNA phylogenetic studies. Introduction and background Actinobacteria are a unique and large group of bacterial species containing five classes, nineteen orders, 50 families and around genera as revealed by the 16S rRNA studies.

Proposal for a new hierarchic classification system, Actinobacteria classis nov. Kocuria spp have been reported to be normal flora of human skin and oral cavity and are usually regarded as laboratory contaminants and ignored when isolated gebus the clinical specimens undermining its pathogenic potential. Moreover, several new cases have expanded the clinical spectrum of disease caused by this unusual pathogen.

All the experimental conditions reconfirmed that PKS was not able to produce biofilm.
