Identification of Leptotrichia goodfellowii infective endocarditis by next-generation sequencing of 16S rDNA amplicons. Cold Spring Harb Mol Case Stud 2021; 7:mcs.a005876.

Abstract
The oral aerotolerant anaerobe Leptotrichia goodfellowii is an unusual cause of endocarditis and is amenable to treatment with β-lactam antibiotics. Because this organism is difficult to identify by conventional methods, molecular detection is a key diagnostic modality. Broad-range 16S rDNA PCR followed by Sanger sequencing constitute the first-line molecular approach, yet poor DNA quality, contaminating DNA, or low template quantity make identification challenging. Here we report a case of culture-negative, aortic and mitral valve endocarditis in a 66-yr-old woman with a history of cardiomyopathy, atrial fibrillation with intracardiac pacer, poor dentition, and recent tooth infection. In this case, 16S rDNA amplicon Sanger sequencing was not sufficient for pathogen identification because of interfering DNA, but deconvolution of the clinical sample using reflexive next-generation amplicon sequencing enabled confident identification of a single pathogenic organism, L. goodfellowii. The patient developed a sigmoid colon perforation and died despite additional surgical treatment. Most Leptotrichia endocarditis cases have been subacute and have been successfully treated with antibiotics, with or without valve replacement. This case highlights both an unusual etiologic agent of endocarditis, as well as the rational utilization of advanced molecular diagnostics tools for characterizing serious infections.

Abstract
BACKGROUND The presence of more than one bacterial agent is relatively rare in infective endocarditis, although more common in prosthetic cases. Molecular diagnosis from a removed heart tissue is considered a quick and effective way to diagnose fastidious or intracellular agents. CASE PRESENTATION Here we describe the case of postpartum polymicrobial prosthetic valve endocarditis in a young woman. Sneathia sanguinegens and Mycoplasma hominis were simultaneously detected from the heart valve sample using broad range 16S rRNA polymerase chain reaction (PCR) followed by sequencing while culture remained negative. Results were confirmed by independent PCR combined with denaturing gradient gel electrophoresis. Before the final agent identification, the highly non-compliant patient left from the hospital against medical advice on empirical intravenous treatment with aminopenicillins, clavulanate and gentamicin switched to oral amoxycillin and clavulanate. Four months after surgery, no signs of inflammation were present despite new regurgitation and valve leaflet flail was detected. However, after another 5 months the patient died from sepsis and recurrent infective endocarditis of unclarified etiology. CONCLUSIONS Mycoplasma hominis is a rare causative agent of infective endocarditis. To the best of our knowledge, presented case is the first report of Sneathia sanguinegens detected in this condition. Molecular techniques were shown to be useful even in polymicrobial infective endocarditis samples.

Subacute Bacterial Endocarditis with Leptotrichia goodfellowii in a Patient with a Valvular Allograft: A Case Report and Review of the Literature. Case Rep Infect Dis 2016; 2016:3051212.

Abstract
Leptotrichia species are normal constituents of the oral cavity and the genitourinary tract microbiota that are known to provoke disease in immunocompromised patients and rarely in immunocompetent individuals. Following the description of Leptotrichia goodfellowii sp. nov., two cases of endocarditis by this species have been reported. Here, we report a case of Leptotrichia goodfellowii endocarditis in an immunocompetent patient with a valvular allograft. The isolation and identification of Leptotrichia can be challenging, and it is likely that infection with this pathogen is significantly underdiagnosed. A definitive identification, as in this case, most often requires 16S rRNA gene sequencing, highlighting the increasingly important role of this diagnostic modality among immunocompetent patients with undetermined anaerobic bacteremia.

Abstract
Although biofilms have been shown to be reservoirs of pathogens, our knowledge of the microbial diversity in biofilms within critical areas, such as health care facilities, is limited. Available methods for pathogen identification and strain typing have some inherent restrictions. In particular, culturing will yield only a fraction of the species present, PCR of virulence or marker genes is mainly focused on a handful of known species, and shotgun metagenomics is limited in the ability to detect strain variations. In this study, we present a single-cell genome sequencing approach to address these limitations and demonstrate it by specifically targeting bacterial cells within a complex biofilm from a hospital bathroom sink drain. A newly developed, automated platform was used to generate genomic DNA by the multiple displacement amplification (MDA) technique from hundreds of single cells in parallel. MDA reactions were screened and classified by 16S rRNA gene PCR sequence, which revealed a broad range of bacteria covering 25 different genera representing environmental species, human commensals, and opportunistic human pathogens. Here we focus on the recovery of a nearly complete genome representing a novel strain of the periodontal pathogen Porphyromonas gingivalis (P. gingivalis JCVI SC001) using the single-cell assembly tool SPAdes. Single-cell genomics is becoming an accepted method to capture novel genomes, primarily in the marine and soil environments. Here we show for the first time that it also enables comparative genomic analysis of strain variation in a pathogen captured from complex biofilm samples in a healthcare facility.

Abstract
A 74-year-old woman visited an otolaryngology clinic with pharyngeal pain, and was diagnosed with a peritonsillar abscess. She received antibiotics and underwent incisional drainage, but displayed high white blood cell and blast cell counts, and was referred to our hospital. Gram-negative rods (Leptotrichia trevisanii) were detected in blood cultures performed on admission. She was diagnosed with bacteremia and acute myelogenous leukemia (FAB classification: M1). After antibiotic therapy, she temporarily recovered from the bacteremia, but subsequently died on day 34. Although Leptotrichia trevisanii bacteremia is extremely rare, clinicians should consider it in cases involving immunocompromised patients with oral lesions.

Abstract
We describe an episode of Leptotrichia trevisanii bacteraemia in a neutropenic hemato-oncology patient receiving chemotherapy for Refractory Anemia with Excess Blasts-2 (RAEB-2). Although Leptotrichia spp. colonize the oral cavity and genitourinary tract, serious episodes of bacteraemia might occur in immunocompromised patients, particularly in those with severe neutropenia. Therefore, microbiologists should consider the possibility of Leptotrichia spp. septicemia in patients with blood cultures positive for gram negative bacilli, when routine microbiology tests fail to reveal a correct identification of the organism.

Abstract
A straight, non-sporulating, Gram-variable bacillus (HKU24(T)) was recovered from the blood culture of a patient with metastatic breast carcinoma. After repeated subculturing in BACTEC Plus Anaerobic/F blood culture broth, HKU24(T) grew on brucella agar as non-hemolytic, pinpoint colonies after 96 h of incubation at 37 degrees C in an anaerobic environment and aerobic environment with 5% CO2. Growth was enhanced with a streak of Staphylococcus aureus. HKU24(T) was non-motile and catalase-negative, but positive for alkaline phosphatase, beta-glucosidase, and alpha-glucosidase. It hydrolyzed phenylphosphonate and reduced resazurin. 16S rRNA, groEL, gyrB, recA, and rpoB sequencing showed that HKU24(T) occupies a distinct phylogenetic position among the Leptotrichia species, being most closely related to Leptotrichia trevisanii. Using HKU24(T) groEL, gyrB, recA, and rpoB gene-specific primers, fragments of these genes were amplified from one of 20 oral specimens. Based on phenotypic and genotypic characteristics, we propose a new species, Leptotrichia hongkongensis sp. nov., to describe this bacterium.

Abstract
The anaerobic bacterium, Leptotrichia buccalis (Lb), belongs to the normal oral flora of humans and is seldom found in clinically significant specimens. However, on rare occasions, Lb has been isolated from blood cultures from patients with lesions of the oral mucosa, in particular from patients with neutropenia. Over a period of 6 months, Lb was isolated from blood cultures in our laboratory from 2 immunocompetent patients. The identification characteristics of Lb are described including the typical morphology at microscopy. Furthermore, we review the bacteraemic cases reported so far together with present knowledge of the pathogenicity and epidemiology of Lb.

Abstract
Leptotrichia species typically colonize the oral cavity and genitourinary tract. These anaerobic bacteria belong to the normal flora of humans and are seldom found in clinically significant specimens. However, on rare occasions, Leptotrichia has been isolated from blood cultures of patients with lesions in the oral mucosa, in particular from patients with neutropenia. These organisms should be considered potential pathogens in neutropenic patients, especially when breaks in the mucosal barriers are present through which they frequently spread to the bloodstream. Leptotrichia has also been recovered from immunocompetent persons, e.g. patients with endocarditis. Although their role in infections remains elusive and not much is known, they have been suggested as emerging pathogens. The present review deals with taxonomy, diagnosis, clinical importance, pathogenesis, host defence, infection control, and spectrum of Leptotrichia infections, and ends with a few typical case reports. Currently, six species have been validly published, but a number of yet uncultivable species exist. Molecular methods recovering uncultivable species should be used to get a real idea of their role as pathogens.

Abstract
Sixty strains of Gram-negative, anaerobic, rod-shaped bacteria from human sources initially assigned to Leptotrichia buccalis (n=58) and 'Leptotrichia pseudobuccalis' (n=2) have been subjected to polyphasic taxonomy. Full-length 16S rDNA sequencing, DNA-DNA hybridization, RAPD, SDS-PAGE of whole-cell proteins, cellular fatty acid analysis and enzymic/biochemical tests supported the establishment of four novel Leptotrichia species from this collection, Leptotrichia goodfellowii sp. nov. (type strain LB 57(T)=CCUG 32286(T)=CIP 107915(T)), Leptotrichia hofstadii sp. nov. (type strain LB 23(T)=CCUG 47504(T)=CIP 107917(T)), Leptotrichia shahii sp. nov. (type strain LB 37(T)=CCUG 47503(T)=CIP 107916(T)) and Leptotrichia wadei sp. nov. (type strain LB 16(T)=CCUG 47505(T)=CIP 107918(T)). Light and electron microscopy showed that the four novel species were Gram-negative, non-spore-forming and non-motile rods. L. goodfellowii produced arginine dihydrolase, beta-galactosidase, N-acetyl-beta-glucosaminidase, arginine arylamidase, leucine arylamidase and histidine arylamidase. L. shahii produced alpha-arabinosidase. L. buccalis and L. goodfellowii fermented mannose and were beta-galactosidase-6-phosphate positive. L. goodfellowii, L. hofstadii and L. wadei were beta-haemolytic. L. buccalis fermented raffinose. With L. buccalis, L. goodfellowii showed 3.8-5.5 % DNA-DNA relatedness, L. shahii showed 24.5-34.1 % relatedness, L. hofstadii showed 27.3-36.3 % relatedness and L. wadei showed 24.1-35.9 % relatedness. 16S rDNA sequencing demonstrated that L. hofstadii, L. shahii, L. wadei and L. goodfellowii each formed individual clusters with 97, 96, 94 and 92 % similarity, respectively, to L. buccalis.

Abstract
We present the case of a 64-year-old previously healthy man admitted for long evoluating fever. Buccal examination showed severe parodontitis. Blood cultures were positive for Leptotrichia buccalis and computed abdominal tomography discovered a hepatic abscess. So far, only exceptional cases of systemic diseases associated with Leptotrichia buccalis infections have been described in immunocompetent patients. Thus, in cases of severe parodontitis and long evoluating fever, attention must be paid to secondary anaerobic infections even in immunocompetent subjects.
