Ioannou P, Vorria A, Samonis G. Cellulosimicrobium Infections in Humans-A Narrative Review. Antibiotics (Basel) 2024; 13:562. [PMID: 38927228 PMCID: PMC11201038 DOI: 10.3390/antibiotics13060562] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2024] [Revised: 06/13/2024] [Accepted: 06/14/2024] [Indexed: 06/28/2024] Open
Abstract
Cellulosimicrobium species (formerly known as Oerskovia) are Gram-positive filamentous bacteria in the family Promicromonosporaceae and are more commonly found in sewage and soil. The present study aimed to identify all the published cases of Cellulosimicrobium species infections in the literature, describe the epidemiological, clinical, and microbiological characteristics, and provide data regarding its antimicrobial resistance, treatment, and outcomes. A narrative review was performed based on a PubMed and Scopus database search. In total, 38 studies provided data on 40 patients with infections by these species. The median age of patients was 52.5 years, and 55% were male. The most common infection types were bacteremia, infective endocarditis (IE), osteoarticular infections, peritoneal dialysis-associated peritonitis, and endophthalmitis. Antimicrobial resistance to vancomycin and the combination of trimethoprim and sulfamethoxazole was minimal, and vancomycin was the most commonly used antimicrobial for treating these infections. Overall mortality was minimal for all infections, except for bacteremia and IE, which carried high mortality rates.

Aviles FA, Kyndt JA. Cellulosimicrobium fucosivorans sp. nov., isolated from San Elijo Lagoon, contains a fucose metabolic pathway linked to carotenoid production. Arch Microbiol 2021; 203:4525-4538.

Abstract
Cellulosimicrobium strain SE3T was isolated from the San Elijo coastal lagoon near San Diego. A whole genome-based phylogenetic comparison shows great heterogeneity within the Cellulosimicrobium genus. Based on average nucleotide identity, whole genome-based comparison, and the presence of a unique L-fucose metabolic pathway, strain SE3T was shown to belong to a novel species within the genus, together with five other strains. The name Cellulosimicrobium fucosivorans sp. nov. is proposed, with strain SE3T as the type strain. The strain encodes a unique alpha-L-fucosidase and the L-fucose metabolic pathway is homologous to the one recently described in Campylobacter jejuni. C. fucosivorans is able to grow on L-fucose, and interestingly, the biosynthesis of the yellow carotenoid is dependent on the presence of L-fucose in the media. The ability to metabolize fucose and the linked production of carotenoids are expected to provide C. fucosivorans with a competitive advantage in the sunny coastal lagoon area.

A case report of the differential diagnosis of Cellulosimicrobium cellulans-infected endocarditis combined with intracranial infection by conventional blood culture and second-generation sequencing. BMC Infect Dis 2020; 20:893. [PMID: 33243151 PMCID: PMC7689970 DOI: 10.1186/s12879-020-05559-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2020] [Accepted: 10/30/2020] [Indexed: 11/25/2022] Open
Abstract
Background Cellulosimicrobium cellulans is a gram-positive filamentous bacterium found primarily in soil and sewage that rarely causes human infection, especially in previously healthy adults, but when it does, it often indicates a poor prognosis. Case presentation We report a case of endocarditis and intracranial infection caused by C. cellulans in a 52-year-old woman with normal immune function and no implants in vivo. The patient started with a febrile headache that progressed to impaired consciousness after 20 days, and she finally died after treatment with vancomycin combined with rifampicin. C. cellulans was isolated from her blood cultures for 3 consecutive days after her admission; however, there was only evidence of C. cellulans sequences for two samples in the second-generation sequencing data generated from her peripheral blood, which were ignored by the technicians. No C. cellulans bands were detected in her cerebrospinal fluid by second-generation sequencing. Conclusions Second-generation sequencing seems to have limitations for certain specific strains of bacteria.

Isolated from Colombian Caribbean soils. ENVIRONMENTAL TECHNOLOGY 2020; 41:2337-2349.

Abstract
Biodiesel is considered to be a natural substitute for fossil fuel. The comparatively low toxicity of biodiesel and its susceptibility to microbial biodegradation could reduce its environmental impact. Currently, biodiesel is sold previously mixed with petroleum-based hydrocarbons. The aim of this work was to measure the biodegradation potential of commercially available biodiesel, using bacterial strains (BBCOL-001, BBCOL-002, and BBCOL-003) isolated from a tropical forest soils in the Colombian Caribbean. According to nucleotide sequencing of the gene encoding for 16S rRNA, the strains belong to members of the genus Cellulosimicrobium. GC-MS analysis showed that biodiesel-oil alkanes were degraded by an average of 81.5% with optical density reaching 0.2-0.3 in minimal salt media at 37°C for 5 days. Individual diesel-oil alkanes were degraded by the strains at rates between 64.9% to 100%. The increase in bacterial biomass confirmed the use of the substrates by the microorganisms, suggesting these hydrocarbons are a carbon source. Changes in the biochemical behaviour of the strains suggested their capacity to adapt to environmental conditions might be an important resource for bioremediation.

Abstract
Background Cellulosimicrobium species, formely known as Oerskovia species, are gram-positive bacilli belonging to the order Actinomycetales. They rarely cause human infections. The genus comprises two pathogenic species in humans: C. cellulans and C. funkei. Based on a case report, we provide a review of the literature of infections caused by Cellulosimicrobium/Oerskovia, in order to improve our knowledge of this unusual infection. Case presentation An 82-year-old woman with aortic prosthetic valve presented to the hospital with fever and heart failure. Further work up revealed the diagnosis of C. cellulans infective endocarditis (IE). The strain was identified by MALDI-TOF MS, API Coryne and 16S rRNA sequencing. The patient was deemed not to be an operative candidate and died despite the antibiotic therapy 35 days after admission. Conclusions Reviewing cases of Cellulosimicrobium species infections and communicating the successful and unsuccessful clinical experiences can assist future healthcare providers. Our case and those previously reported indicate that Cellulosimicrobium species usually infect immunocompromised patients or foreign body carriers. The most frequent pattern of infection is central venous catheter related bacteremia. The optimal treatment should include foreign body removal and valve surgery should be considered in case of IE.

Bacteremia caused by cellulosimicrobium in a bone marrow transplant patient: A case report and literature review. IDCases 2018; 11:64-66. [PMID: 29619323 PMCID: PMC5881518 DOI: 10.1016/j.idcr.2018.01.007] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2017] [Revised: 01/16/2018] [Accepted: 01/17/2018] [Indexed: 11/23/2022] Open
Abstract
Background Cellulosimicrobium sp. is a ubiquitous gram-positive bacillus that was formerly known as Oerskovia. This bacterium is found in soil and decaying plant material and is rarely associated with infections in humans. Case report We report the case of a 44 year-old woman with history of bone marrow transplant that developed Cellulosimicrobium sp. bacteremia secondary to a central line infection. She was admitted with presumed sepsis. Blood cultures from central line and periphery revealed the growth of gram-positive rods that were further identified as Cellulosimicrobium sp. by MALDI-TOF. She was treated with vancomycin and line removal. Microbiologic cure was achieved; however, she developed hospital-acquired pneumonia, which led to a fatal outcome. Conclusion To our knowledge, there are only 15 documented cases of Cellulosimicrobium sp. bacteremia. Our case illustrates the potential pathogenicity of this bacterium and the importance of appropriate antimicrobial therapy and removal of infected central catheters. It is essential to know that gram-positive bacilli should not be disregarded as contaminants when recovered from multiple blood cultures. In this situation, a full microbiologic identification must be attempted.

Abstract
Cloacal or fecal Gram's stains and bacterial cultures are routinely performed during avian physical examinations to assess the microbial flora of the gastrointestinal tract. Although cloacal or fecal Gram's stains and bacterial cultures are considered routine diagnostic procedures, the level of agreement between the individual tests has not been determined. To investigate the level of agreement between results from Gram's stain and bacterial culture when used to assess cloacal or fecal samples from psittacine birds, samples were taken from 21 clinically healthy Hispaniolan Amazon parrots ( Amazona ventralis ) and tested by Gram's stain cytology and bacterial culture. Most bacteria (97.2%) identified by Gram's stain were gram positive. However, gram-negative organisms were identified in 7 of 21 (33.3%; 95% confidence interval: 13.3%-53.3%) birds. Escherichia coli was the only gram-negative organism identified on culture. Agreement between results of Gram's stain and culture was fair (weighted κ = 0.27). The results of this study suggest that Gram's stains and bacterial culture may need to be performed with a parallel testing strategy to limit the likelihood of misclassifying the microbial flora of psittacine patients.

Abstract
Cellulosimicrobium cellulans has been reported as a rare cause of human pathogenesis. Infections mainly occur in immunocompromised patients and very often are associated with a foreign body. We report the first case of septic arthritis caused by C. cellulans in an immunocompetent patient. Our patient suffered a penetrating palm tree thorn injury to his left knee 8 weeks before admission. Although no foreign objects were found, they were suspected because previous reports suggest a frequent association with this microorganism, and open debridament was performed. Removal of foreign bodies related to this organism must be considered a high-priority treatment in these patients to achieve a complete recovery.
