“…Particullarly, patients who have undergone and hematopoietic stem-cell transplantation and who received high-dose chemotherapy, Leptotrichia species have been identified as major pathogens of bacteremia [12]. Chorioamnionitis and pelvic inflammatory diseases have also been reported to be caused by L. trevisanii [19, 20]. Therefore, Leptotrichia species as emerging pathogens can cause Leptotrichia anaerobic bloodstream infection in immunocompromised patients.…”

BackgroundLeptotrichia species are aerotolerant, Gram-negative fusiform bacteria. Cases of bacteremia caused by Leptotrichia trevisanii in immunocompromised patients have been rarely reported.Case presentationA 33-year-old female with systemic lupus erythematosus (SLE) was admitted to the department of rheumatology with bleeding from a mucosal ulcer. One month previously, she had visited our hospital and begun to receive methotrexate therapy, but mis-dosed for nearly 1 month at home. Methotrexate toxicity resulted in a severe oral ulcer and bone marrow suppression. On day-7 of hospital admission, she developed a fever, and Gram-negative rods (Leptotrichia trevisanii) were detected in blood cultures. She was diagnosed with methotrexate poisoning followed by L. trevisanii bacteremia. After antibiotic and detoxification therapy, she recovered from bacteremia, and the oral ulcer and bone-marrow suppression improved obviously.ConclusionsThis is the first reported case of Leptotrichia trevisanii bacteremia in a SLE patient who took mis-dosed an immunosuppressant and had an oral mucosal lesion.

“…Leptotrichia species are thin anaerobic gramnegative rods that inhabit multiple areas in the human body, including the oral cavity, gastrointestinal tract, the urogenital system, and the female genital tract [1,2]. Leptotrichia species are considered opportunistic pathogens and have been isolated in cases of periodontitis and mucositis in the oral cavity [3], chorioamnionitis in the female genital tract [4,5], and endocarditis [6,7]. A preponderance of reported cases of Leptotrichia are cases of bacteremia, and they were mainly reported in neutropenic patients with various forms of predisposing conditions such as bone-marrow transplants [1,2].…”

Here we present four clinical cases of immunocompromised patients experiencing bacteremia caused by Leptotrichia species in a few months with no common epidemiological link. Leptotrichia species are thin anaerobic gram-negative rods that inhabit multiple areas in the human body, including the oral microbiota. Many infections with Leptotrichia species occur in immunocompromised individuals classifying Leptotrichia species as opportunistic pathogens. Utilization of standard microbial identification methods of matrix-assisted laser-desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) initially yielded the same identification for all four Leptotrichia isolates as Leptotrichia buccalis. However, 16S ribosomal RNA sequencing confirmed the identification of only one of the four isolates as L. buccalis, while two of the four isolates were identified as Leptotrichia trevisanii. These four cases highlight the clinical importance of considering opportunistic infection in immunocompromised patients with unusual organisms considered members of the normal oral flora.

Emergent genital infection by Leptotrichia trevisanii

et al. 2018

We report the first case of an association between Leptotrichia trevisanii and an episode of pelvic inflammatory disease (PID) and the second case of the isolation of this infection in the cervical canal. A 45-yr-old woman was admitted to our emergency department with clinical and radiological signs and symptoms compatible with an episode of PID. She was hospitalized for intravenous antibiotic control and treatment and the subsequent surgical drainage of abscesses. Cultures were taken throughout the process, but only cultures from cervical canal exudate were positive, with the growth of L. trevisanii species. It appears important to carry out a complete microbiological screening, not limited to conventional agents, on adequate clinical samples to detect possible infectious agents that may be missed in these cases.
