Loop-mediated isothermal amplification assays for the rapid discrimination of <i>Treponema pallidum</i> lineages and subspecies Open
Molecular surveillance aimed at identifying the subspecies and lineages of Treponema pallidum is important. Conventional molecular methods for genotyping are effective but are also time-consuming and costly. This study aimed to develop and…

Development and clinical evaluation of a novel SHERLOCK test for <i>Mycoplasma genitalium</i> Open
Mycoplasma genitalium (MG) is a sexually transmitted pathogen associated with urethritis. Nucleic acid amplification tests are the gold standard for its diagnosis but often require specialized equipment, which limits their use in point-of-…

Evaluation of the GeneSoC rapid quantitative PCR system for Treponema pallidum detection Open
The incidence of syphilis, caused by Treponema pallidum (TP), is increasing worldwide. Nucleic acid amplification tests, including quantitative PCR (qPCR), are valuable for diagnosing primary syphilis, particularly using ulcer/lesion swabs…

Prospective evaluation of non-invasive saliva specimens for the diagnosis of syphilis and molecular surveillance of <i>Treponema pallidum</i> Open
The promising diagnostic performance of molecular testing for syphilis using saliva and urine samples has been reported; however, further evaluation of its possible application for diagnosis and molecular surveillance is required. In addit…

Acute cholangitis caused by coinfection with zoonotic pathogens of Gallibacterium anatis and Enterococcus cecorum: A case report Open
A common bile duct stone that impairs bile flow is a risk factor for G. anatis and E. cecorum infection in an immunocompetent host. This report indicates the need for further surveillance of G. anatis and E. cecorum in animals as well as f…

A fatal case of peritonitis caused by Dysgonomonas capnocytophagoides harboring the novel metallo-beta-lactamase gene bla Open
Dysgonomonas capnocytophagoides shows multidrug resistance to antibiotics and causes opportunistic infections in immunocompromised hosts. The drug resistance mechanisms of D. capnocytophagoides have not yet been identified. In this work, w…

Retrospective investigation of overlooked Mpox virus infection in saliva samples from patients with suspected syphilis in Japan Open
The clinical presentation of Mpox (monkeypox) resembles that of several other sexually transmitted infections. Although cases of Mpox are thought to be overlooked in the clinical setting, no study has investigated whether this is the case …

A fatal case of peritonitis caused by<i>Dysgonomonas capnocytophagoides</i>harboring the novel metallo-beta-lactamase gene<i>bla</i><sub><i>DYB-1</i></sub> Open
Dysgonomonas capnocytophagoides shows multidrug resistance to antibiotics and causes opportunistic infections in immunocompromised hosts. We report a fatal case of peritonitis caused by D. capnocytophagoides in Japan. We identified a novel…
