“…They are a part of the normal flora of the oropharyngeal and genital tracts of humans and animals. Among the genus Leptotrichia, the type species, Leptotrichia buccalis, mostly reported as human pathogen, is involved in bacteremia in immunocompromised patients (10,12). More rarely, distinct Leptotrichia species (5.79% nucleotide sequence divergence) were reported in neutropenic patients as agents of bacteremia (9).…”

We report three cases of delivery and postpartum bacteremia due to unusual anaerobic bacteria in healthy young women. Leptotrichia amnionii bacteremia occurred during delivery in two mothers and was associated with fetal distress during labor. Conversely, Sneathia sanguinegens bacteremia occurred postpartum, 2 days after delivery, without consequence for the neonate. CASE REPORTS Case 1.A 36-year-old woman from North Africa who was living in France had a pregnancy without complications. Vaginal delivery was associated with fetal distress during labor (acidosis, abnormal cardiac rhythm, and colored amniotic liquid), and a maternal postpartum fever up to 39°C occurred rapidly 1 h after delivery. Three blood cultures from peripheral veins were obtained after delivery but before any antibiotic administration. Each blood culture consisted of a pair of BACTEC PLUS Aerobic/F and Anaerobic/F culture vials (BD, Meylan, France). After blood cultures were obtained, the patient was treated with intravenous antibiotic therapy. One gram of intravenous amoxicillin was administered three times per day. Within 10 days of antibiotic therapy, the patient had recovered completely. The newborn did not develop postnatal clinical or laboratory evidence of infection despite initial fetal distress during labor.Case 2. A 32-year-old woman from Turkey who was living in France had a pregnancy without complications. Vaginal delivery was as described above for case 1, and a maternal postpartum fever up to 39°C occurred rapidly 1 h after delivery. Three blood cultures from peripheral veins were obtained after delivery but before any antibiotic administration. Each blood culture consisted of a pair of BACTEC PLUS Aerobic/F and Anaerobic/F culture vials. After blood cultures were obtained, the patient was treated with intravenous antibiotic therapy. One gram of intravenous amoxicillin was administered three times per day. However, because of fever relapse, clavulanic acid was added on the third day. On day 6, this patient developed another febrile episode, while her white blood cell count and C-reactive protein levels were normal and additional blood cultures remained negative. Within 10 days of antibiotic therapy, the patient had recovered completely. The newborn did not develop postnatal clinical or laboratory evidence of infection despite initial fetal distress during labor.Case 3. A 21-year-old woman from Turkey who was living in France had a pregnancy without complications. Vaginal delivery was without fetal distress, but the patient presented with fever up to 39°C 2 days after delivery. Three blood cultures from peripheral veins were obtained after delivery but before any antibiotic administration. Each blood culture consisted of a pair of BACTEC PLUS Aerobic/F and Anaerobic/F culture vials. After blood cultures were obtained, the patient was treated intravenously with 1 g of amoxicillin-clavulanic acid three times per day, 500 mg of metronidazole two times per day, and 100 mg of netilmicin two times per day for 4 days, which was then sw...

“…After excluding two cases for which insufficient clinical information was provided, we investigated the clinical findings of the remaining 33 cases and our patient [34 cases in total; Table 2 (3,4,(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)]. The patients' ages ranged from three to 84 years (mean: 43.7 years), and there were 17 men and 17 women.…”

Acute Myelogenous Leukemia with <i>Leptotrichia trevisanii</i> Bacteremia

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.

OBJECTIVE: To subject ten clinical isolates grouped together based on their biochemical and microbiological profile to further investigations aimed at correct species identification. METHODS: The 16S rRNA gene was partially sequenced using nested amplification. Whole cell protein analysis (SDS-PAGE) and cluster analysis were performed on the 10 strains and also for comparison on 31 reference strains. The API Coryne biochemical kit as well as API 20 Strep were used for analysis of the phenotypic diversity of the strains by use of computerized numerical identification procedures. Antibiotic susceptibility testing was performed using a standardized disk diffusion test. RESULTS: The 265--556-bp-long 16S rRNA gene sequences of all 10 strains showed highest similarity to Rothia dentocariosa. Three strains showed complete identity between the sequences obtained and the sequence of the type strain of Rothia dentocariosa 16S rRNA gene (M59055), and the other seven ranged between 99.7% and 98.3% similarity. Detailed analysis of the sequences revealed a clustering of the strains into two groups. One group consisted of four isolates with the highest degrees of similarity with the reference strain (type I), while the members of another group (type II) showed differences in their nucleotide sequence at four distinct positions in the variable V7 region. T was replaced by C at position 597, C by T at position 608, T by C at position 610, and G by A at position 684 (position numbers according to reference sequence M59055, EMBL/GenBank). Whole cell protein analysis (SDS-PAGE) and cluster analysis also segregated the 10 Rothia dentocariosa strains into two different clusters, with one cluster containing all four strains belonging to 16S rRNA gene type I, and a second cluster containing all six strains belonging to 16S rRNA gene type II. CONCLUSIONS: Partial sequence data of the 16S rRNA gene as well as whole cell protein analysis showed a subdivision of the Rothia species into two groups, genomovar I (Rothia dentocariosa sensu stricto) and genomovar II, a possible new Rothia species.
