Abstract
Following the COVID-19 infection, the sternum dislocation and wound dehiscence resulted in an infection complicating the recovery of an immunosuppressed patient after bilateral lung transplantation. Anaerobic culture (96 h) of milky cloudy wound secretion resulted in the growth of pinpoint haemolytic colonies identified as Metamycoplasma hominis (formerly Mycoplasma hominis). The search for the endogenous source of the infection found the bacterium exclusively in the patient's sputum, making a possible link to donor lung M. hominis colonization. Unfortunately, the donor samples were no longer available. The wound infection was successfully treated with 17 days of clindamycin despite the continuous PCR detection of M. hominis in the sputum after the end of the treatment.

Abstract
Background Mycoplasma hominis (M. hominis) commonly colonizes the genitourinary tract of adult women and may result in neonatal meningitis through vertical transmission. Although there are few case reports, if the treatment is not conducted timely, the disease progresses rapidly, which may lead to serious complications and a poor prognosis. Case presentation In the present study, a 10-day-old full-term neonate who presented with fever as the initial symptom and was eventually diagnosed with meningitis caused by M. hominis was reported. In the present case, the pathogen was not detected during the initial routine investigations, and the therapeutic effects of empiric antibiotic therapy were poor. Metagenomic next-generation sequencing (mNGS) in the cerebrospinal fluid (CSF) was conducted with the detection of M. hominis, and the antibiotics were adjusted to moxifloxacin combined with doxycycline. The clinical symptoms of the pediatric patient disappeared with an improvement in related laboratory results. Conclusion It was difficult to detect M. hominis by routine bacterial culture. Therefore, M. hominis infection should be checked for in children with meningitis who had a negative result in CSF culture and poor therapeutic effects of empirical medication. mNGS in CSF should be conducted as soon as possible, and sensitive antibiotics should be administered in time to reduce the incidence of complications and improve the prognosis.

Abstract
BACKGROUND Mycoplasma hominis is a facultative anaerobic bacterium commonly present in the urogenital tract. In recent years, M. hominis has increasingly been associated with extra-urogenital tract infections, particularly in immunosuppressed patients. Detecting M. hominis in a diagnostic laboratory can be challenging due to its slow growth rate, absence of a cell wall, and the requirements of specialized media and conditions for optimal growth. Consequently, it is necessary to establish guidelines for the detection of this microorganism and to request the appropriate microbiological work-up of immunosuppressed patients. CASE PRESENTATION We hereby present two cases of solid organ transplant patients who developed M. hominis infection. Microscopic examination of the bronchial lavage and pleural fluid showed no microorganisms. However, upon inoculating the specimens onto routine microbiology media, the organism was successfully identified and confirmation was performed using 16S rDNA sequencing. Both patients received appropriate treatment resulting in the resolution of M. hominis infection. CONCLUSIONS The prompt detection of M. hominis in a clinical specimen can have a significant impact on patient care by allowing for early intervention and ultimately resulting in more favorable clinical outcomes, especially in transplant patients.

Abstract
RATIONALE Postoperative intracranial mycoplasma hominis infection was a rare complication. Timely diagnosis was difficult due to its growth characteristics and nonspecific clinical symptoms. PATIENT CONCERNS A 52-year-old man underwent bilateral decompressive craniotomy for severe traumatic brain injury. On the seventeenth day after surgery, the patient developed an unexplained high fever. Empirical anti-infective therapy was ineffective, and the fever persisted. In addition, viscous pus oozed from the head incision. Empiric therapy was still ineffective, the fever persisted, and the culture result was negative. The lumbar puncture pressure was 150 mmH2O and the cerebrospinal fluid white blood cell count was 3600 × 106/L, suggesting an intracranial infection. DIAGNOSES Culture growth morphologically consistent with mycoplasma species was obtained from multiple specimens (scalp incision fluid and cerebrospinal fluid) and the identification of mycoplasma hominis was confirmed by 16S rDNA sequencing. INTERVENTION Targeted anti-infective therapy (Minocycline), change of fresh wound dressing, and continued lumbar cerebrospinal fluid drainage. OUTCOME At the 3-month follow-up, the patient was still in the rehabilitation department of the local hospital for treatment, but there were no symptoms of intracranial infection. LESSONS Neurosurgeons should carefully examine postoperative incisions and be aware of the possibility of mycoplasma infection during clinical management.

Abstract
BACKGROUND Mycoplasma hominis is one of the main opportunistic pathogenic mycoplasmas in humans which has a major impact on patients with bloodstream infections. Because it is difficult to detect or isolate, rapid and accurate diagnosis using improved methods is essential and still challenging for patients with bloodstream infection. CASE PRESENTATION In this case, we reported the application of next -generation sequencing for the diagnosis of bloodstream infection caused by Mycoplasma hominis in a patient with Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis. After 9 days of combined treatment with levofloxacin, polymyxin B and meropenem, the patient's condition was gradually controlled and he was discharged without further complications. During the three-month outpatient follow-up, no recurrence of symptoms or clinical signs was reported. CONCLUSIONS This successful application of next generation sequencing assisted the rapid diagnosis of Mycoplasma hominis bloodstream infection, provided a new perspective in the clinical approach and highlighted the potential of this technique in rapid etiological diagnosis.

Abstract
Mycoplasma hominis is a commensal pathogen normally found in urogenital tract of humans and has been associated with a wide variety of extra-genitourinary infections, such as mediastinitis, bacteremia, and septic arthritis, particularly in immunocompromised patients. Here, we present a case of a 48-year-old male, who had been treated with fingolimod for relapsing multiple sclerosis and presented with fever and right-sided hip pain following total hip arthroplasty. CT scan revealed localized fluid collection in the right quadriceps femoris muscle adjacent to the joint cavity of right hip. The percutaneously aspirated fluid grew M. hominis, which was also isolated from blood culture. With diagnosis of periprosthetic joint infection, the patient underwent surgical debridement with retained prosthesis and was treated with antimicrobial agents. Infected granulation tissues excised from the hip was observed under an electron microscope, which revealed electron-dense rounded structures contained in neutrophils, consistent with Mycoplasma particles. Fingolimod, an immunomodulatory drug that acts on the sphingosine-1-phosphate receptor and prevents the egress of lymphocytes from lymph nodes, might increase host susceptibility to a systemic M. hominis infection.
