Abstract
Cedecea lapagei is a gram-negative, non-encapsulated, facultative anaerobic bacterium that has been reported in only a few cases with varying clinical presentations, drug susceptibility, and treatment since its first isolation in 1981. This study aimed to describe a case report of C. lapagei in Peru and systematically review the documented case reports of individuals infected with C. lapagei. A 59-year-old man who had become bedridden with Parkinson's disease and had epilepsy presented with a 1-week history of fever and sore throat and was admitted. Physical examination revealed an obtundation state and abolished vesicular murmur in the right hemithorax. During hospitalization, the patient was diagnosed with various infections, including tuberculosis, for which he received broad-spectrum antibiotics. In the absence of clinical improvement, a urine culture was performed showing C. lapagei (detected by BD Phoenix M50 system, Vernon Hills, IL). The patient received amoxicillin/clavulanate and was discharged. Case reports of C. lapagei were also searched in five databases on January 28, 2023. Twenty cases of C. lapagei were reported worldwide between 2006 and 2022, 16 of which involved adults. Fever was the most common manifestation (75%), and pneumonia was the primary form of presentation (45%). Moreover, 90% of the patients had at least one comorbidity, and 15% died. Also, most of the isolates were sensitive to ciprofloxacin (81%), meropenem (62%), and amikacin (60%). Overall, C. lapagei should be suspected in compromised hosts, particularly those with pneumonia. Although the bacterium can affect various organs and the antibiotic susceptibility pattern is variable, quinolones, tetracyclines, and carbapenems seem to be the first therapeutic option.

Thompson DK, Sharkady SM. Genomic Insights into Drug Resistance Determinants in Cedecea neteri, A Rare Opportunistic Pathogen. Microorganisms 2021; 9:microorganisms9081741. [PMID: 34442820 PMCID: PMC8401664 DOI: 10.3390/microorganisms9081741] [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: 07/22/2021] [Revised: 08/09/2021] [Accepted: 08/13/2021] [Indexed: 11/16/2022] Open
Abstract
Cedecea, a genus in the Enterobacteriaceae family, includes several opportunistic pathogens reported to cause an array of sporadic acute infections, most notably of the lung and bloodstream. One species, Cedecea neteri, is associated with cases of bacteremia in immunocompromised hosts and has documented resistance to different antibiotics, including β-lactams and colistin. Despite the potential to inflict serious infections, knowledge about drug resistance determinants in Cedecea is limited. In this study, we utilized whole-genome sequence data available for three environmental strains (SSMD04, M006, ND14a) of C. neteri and various bioinformatics tools to analyze drug resistance genes in this bacterium. All three genomes harbor multiple chromosome-encoded β-lactamase genes. A deeper analysis of β-lactamase genes in SSMD04 revealed four metallo-β-lactamases, a novel variant, and a CMY/ACT-type AmpC putatively regulated by a divergently transcribed AmpR. Homologs of known resistance-nodulation-cell division (RND)-type multidrug efflux pumps such as OqxB, AcrB, AcrD, and MdtBC were also identified. Genomic island prediction for SSMD04 indicated that tolC, involved in drug and toxin export across the outer membrane of Gram-negative bacteria, was acquired by a transposase-mediated genetic transfer mechanism. Our study provides new insights into drug resistance mechanisms of an environmental microorganism capable of behaving as a clinically relevant opportunistic pathogen.

Abstract
Lipoxygenases are found in animals, plants, and fungi, where they are involved in a wide range of cell-to-cell signaling processes. The presence of lipoxygenases in a number of bacteria and protozoa has been also established, but their biological significance remains poorly understood. Several hypothetical functions of lipoxygenases in bacteria and protozoa have been suggested without experimental validation. The objective of our study was evaluating the functions of bacterial and protozoan lipoxygenases by evolutionary and taxonomic analysis using bioinformatics tools. Lipoxygenase sequences were identified and examined using BLAST, followed by analysis of constructed phylogenetic trees and networks. Our results support the theory on the involvement of lipoxygenases in the formation of multicellular structures by microorganisms and their possible evolutionary significance in the emergence of multicellularity. Furthermore, we observed association of lipoxygenases with the suppression of host immune response by parasitic and symbiotic bacteria including dangerous opportunistic pathogens.

Expanding spectrum of opportunistic Cedecea infections: Current clinical status and multidrug resistance. Int J Infect Dis 2020; 100:461-469. [PMID: 32950733 DOI: 10.1016/j.ijid.2020.09.036] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2020] [Revised: 09/07/2020] [Accepted: 09/13/2020] [Indexed: 12/16/2022] Open
Abstract
Members of the bacterial genus Cedecea cause acute infections worldwide in compromised hosts with serious underlying medical conditions. While global reports of Cedecea infections remain sporadic in the medical literature, cases of multidrug-resistant clinical isolates have been documented each year over the past decade, warranting a comprehensive update on this emerging opportunistic pathogen. Here, we review the clinical manifestations, pathogenesis, natural distribution, epidemiology, and antimicrobial resistance of Cedecea species. Acute infection commonly manifests as bacteremia and pneumonia; however, the spectrum of infectious pathologies associated with Cedecea has expanded to include oral and cutaneous ulcers, orbital cellulitis, and peritonitis. The frequency of resistance among reported clinical isolates was highest to ampicillin, cephalothin, cefoxitin, cefazolin, and ceftazidime. Cedecea isolates harboring metallo-β-lactamases exhibited resistance to carbapenems and fourth-generation cephalosporins. Further research is needed to understand the pathogenicity and multidrug resistance of Cedecea species. Appropriate therapeutic management of Cedecea infections depends on antibiotic susceptibility testing because of variable resistance patterns and the enhanced infection risk in vulnerable populations.

Abstract
A 45-year-old man presented with acute sinusitis. He was treated with a 10-day course of trimethoprim/sulfamethoxazole, and a subsequent 14-day course of amoxicillin-clavulanate with no improvement in symptoms. Culture of purulent nasal secretions revealed the rare enterobacter Cedecea lapagei The patient had complete resolution of his symptoms after a 14-day course of gentamicin/dexamethasone nasal rinses. Emerging pathogens have been a timeless concern for physicians, as witnessed by the current SARS-CoV-2 outbreak. C. lapagei has been reported to cause human infection only a dozen times since its discovery, all in severely compromised patients. This is the first documented case of sinusitis reported with C. lapagei and may portend a rising prevalence of disease burden in the general population. This case demonstrates the necessity of obtaining cultures when standard antibiotics result in treatment failure.

J Med Case Rep 2018; 12:328.

Abstract
Background Cedecea lapagei bacterium was discovered in 1977 but was not known to be pathogenic to humans until 2006. In the medical literature there are very few clinical case reports of Cedecea lapagei; none have reported a catastrophic death secondary to a soft tissue hemorrhagic bullae infection. As well as soft tissue infection, rare cases of pneumonia, urinary tract infections, peritonitis, osteomyelitis, bacteremia, and sepsis have been documented with the majority having good outcomes. Here, we present the first case of a fatal outcome in a Cedecea lapagei soft tissue infection with multiple hemorrhagic bullae. Case presentation A 52-year-old Mexican man with antecedents of liver cirrhosis and treated hypertension was brought to our institution with clinical signs of sepsis and 16 to 18 hours of history of pain and edema in his right lower limb. During the course of the first day hospitalized in our institution, he developed several large serohematogenous bullae with ascending progression on his entire right lower limb. He subsequently developed multiple organ failure and septic shock with rapid deterioration, dying on the second day. Bullae fluid samples taken the first day undoubtedly isolated Cedecea lapagei within the second day using MicroScan WalkAway® 96 plus System as well Gram-negative bacteria in MacConkey and blood agar. Conclusions The isolation of Cedecea lapagei was an unexpected etiological finding that will enable physicians in the future to consider this bacterium as a probable cause of serohematogenous bullae infections. We do not exclude contamination although it has never been isolated in bullae fluid in the medical literature. Future encounters with this bacterium should not be taken lightly as it may have the potential to have fatal outcomes.

Abstract
Cedecea neteri, a member of the Enterobacteriaceae family, has only been identified as a human pathogen in a few previous clinical cases, thus complicating assessment of this organism's pathogenicity and medical relevance. Documented infections attributed to C. neteri primarily involved bacteremia in severely immunocompromised patients. We report a rare case of urinary catheter colonization by a multidrug-resistant C. neteri strain in a patient of advanced age with benign prostatic hyperplasia and other chronic comorbidities. This C. neteri isolate was resistant or intermediate to second-generation cephalosporins, penicillins, and certain β-lactamase inhibitor/β-lactam combinations. Analysis of whole genome sequence information for a representative C. neteri strain indicated the presence of multiple open reading frames with sequence similarity to β-lactamases, including a chromosome-encoded AmpC β-lactamase and metallo-β-lactamases, consistent with the resistance phenotype of this bacterium. The presence of an AmpR homolog suggests that the C. neteriampC may be inducible in response to β-lactam exposure. Molecular insights into antibiotic resistance traits of this emerging opportunistic pathogen will be important for administering adequate antibiotic treatment to ensure favorable patient outcomes.
