Epidemiological studies worldwide have reported a high prevalence and a great diversity of Bartonella species, both in rodents and their flea parasites. The interaction among Bartonella, wild rodents, and fleas reflects a high degree of adaptation among these organisms. Vertical and horizontal efficient Bartonella transmission pathways within flea communities and from fleas to rodents have been documented in competence studies, suggesting that fleas are key players in the transmission of Bartonella to rodents. Exploration of the ecological traits of rodents and their fleas may shed light on the mechanisms used by bartonellae to become established in these organisms. The present review explores the interrelations within the Bartonella-rodent-flea system. The role of the latter two components is emphasized.

“…Bacterial DNA was extracted as previously described (4), and the 16S rRNA gene was amplified according to the previously published procedures (1,12). The amplified fragments were purified with a CHROMA SPIN 100 column (Clontech, Palo Alto, Calif.) according to the manufacturer's recommendations.…”

Dialister pneumosintes Associated with Human Brain Abscesses

et al. 2002

In this report, we review two cases of brain infection due to Dialister pneumosintes in previously healthy patients. The bacterium was isolated from the first patient by blood culture and directly from a brain abscess in the second patient. In both cases, the infection was suspected to be of nasopharyngeal or dental origin. The patients had favorable outcomes following surgical debridement and antibiotic treatment. After in vitro amplification and partial sequencing of the 16S rRNA gene, two strains were classified as D. pneumosintes. However, traditional biochemical tests were not sufficient to identify the bacteria. In addition to causing periodontal and opportunistic infections, D. pneumosintes, contained in mixed flora, may behave as a clinically important pathogen, especially in the brain. In addition to phenotypic characterization, 16S rRNA partial sequencing was used to identify D. pneumosintes definitively. CASE REPORTSCase 1. A 17-year-old man was admitted to Strasbourg University Hospital for fever and dysphagia that had evolved over 1 week. Prior to admission, he had received amoxicillin and then clarithromycin. On physical examination, he presented with a high fever (40°C), right temporal headache, paralysis of the left arm, and swelling of the submandibular lymph nodes. Laboratory investigations revealed an inflammatory syndrome with a C-reactive protein level measuring 118 mg/liter and a leukocyte count of 13.3 ϫ 10 9 cells/liter. Standard cerebrospinal fluid analysis as well as aerobic and anaerobic cultures did not reveal any abnormalities. Two aerobic and anaerobic blood cultures (BACTEC Plus Aerobic/F and BACTEC Plus Anaerobic/F; BD, Pont-de-Claix, France) were performed upon admission.A brain computerized tomography (CT) scan revealed a subdural empyema compressing the right frontal lobe. Arteriography of the cerebral vessels revealed possible thrombophlebitis of the longitudinal median sinus. Antimicrobial treatment with cefotaxime at 12 g/day, metronidazole at 1.5 g/day, and acyclovir at 2.4 g/day was started. The general condition of the patient rapidly worsened, leading to sepsis and aggravation of his neurologic symptoms. On the second day after admission, a right frontal craniotomy was performed. A subdural empyema was evacuated and the frontal sinuses were drained. Thiamphenicol (750 mg) was injected into the operative cavity. Postsurgical treatment consisted of metronidazole, cefotaxime, ofloxacin, carbamazepine, and heparin.Gram staining of the empyema revealed numerous polymorphonuclear cells and small gram-negative rods. Rare colonies of Streptococcus anginosus grew on chocolate agar under aerobic conditions and also on blood agar supplemented with hemin and vitamin K 1 under anaerobic conditions. Rare colonies of S. anginosus and coagulase-negative Staphylococcus were isolated from the frontal sinus sample. On the fourth day of hospitalization, Dialister pneumosintes (IBS 708/99) was obtained from one of the blood cultures done on the day of admission. All other blood cultures done...

“…During the last three decades, numerous surveys have been conducted in a variety of rodent communities at many locations. These surveys demonstrated that bartonellae are widely distributed in rodents of numerous species in all continents (Birtles et al,1994;Kosoy et al, 1997;Heller et al, 1998;Hofmeister et al, 1998;Laakkonen et al, 1998;Bermond et al, 2000;Fichet-Calvet et al, 2000;Bajer et al, 2001;Bown et al, 2002;Holmberg et al, 2003;Engbaek & Lawson, 2004;Gundi et al, 2004;Pawelczyk et al, 2004;Pretorius et al, 2004;Tea et al, 2004;Jardine et al, 2005;Kim et al, 2005;Telfer et al, 2005;Markov et al, 2006;Knap et al, 2007). The very first investigation of bartonella infection in rodents from tropic areas was conducted in Yunnan, a province located in southwestern China (Ying et al, 2002).…”
