Abstract
The strain Marseille-P2749T (= CSUR P2749 = DSM 103085) was isolated as part of culturomics study from a liquid duodenum sample from a French man. Bacterial cells were Gram-negative bacilli, fusiform shaped and non–spore forming, and they grew in microaerophilic and anaerobic atmosphere. Its genome is 1 809 169 bp long and contains 1646 protein-coding genes. The DNA G+C content was 27.33 mol%. This strain exhibited a 95.9% sequence similarity with Fusobacterium periodonticum, the phylogenetically closest species with standing in nomenclature. Strain Marseille-P2749T is suggested to be a novel species belonging to the genus Fusobacterium, for which the name Fusobacterium massiliense sp. nov. is proposed.

Abstract
Preexposure prophylaxis (PrEP) against HIV is currently the subject of great interest, as clinical trials have shown high efficacy in terms of decreasing transmission among men who have sex with men. Because the prevalence of bacterial sexual transmitted infections (STIs) is increasing within this community, a recent pilot study demonstrated the efficacy of reducing transmission of bacterial STIs by administering PrEP with daily doxycycline to men who have sex with men. This creative initiative raises several questions which are discussed in this review. Relevant information should be drawn from the huge amount of available epidemiologic data to identify those who could benefit from such prophylactic treatment. The choice of antimicrobial agents is crucial, as antimicrobial susceptibility of STI agents is heterogeneous. Finally, we discuss challenges to improve the control of STIs through the use of PrEP.

Abstract
Molecular tools have shown an added value in the diagnosis of infectious diseases, in particular for those caused by fastidious intracellular microorganisms, or in patients receiving antibiotics before sampling. If 16S rDNA amplification had been gradually implemented in microbiology laboratories, specific real-time polymerase chain reaction (PCR) would have permitted an increase in the sensitivity of molecular methods and a reduction of contamination. Herein, we report our experience in the diagnosis of infectious diseases over two years, during which 32,948 clinical samples from 18,056 patients were received from France and abroad. Among these samples, 81,476 PCRs were performed, of which 1,192 were positive. Molecular techniques detected intracellular microorganisms in 31.3 % of respiratory samples, 27.8 % of endocarditis samples and 51.9 % of adenitis samples. Excluding intracellular bacteria, 25 % of the positive samples in this series were sterile in culture. Conventional broad-range PCR permitted the identification of fastidious and anaerobic microorganisms, but specific real-time PCR showed a significant superiority in the diagnosis of osteoarticular infections, in particular for those caused by Kingella kingae and Staphylococcus aureus, and for endocarditis diagnosis, specifically when Streptococcus gallolyticus and Staphylococcus aureus were involved. The sensitivity of conventional broad-range PCR was 62.9 % concerning overall diagnoses for which both techniques had been performed. These findings should lead microbiologists to focus on targeted specific real-time PCR regarding the clinical syndrome. Finally, syndrome-driven diagnosis, which consists of testing a panel of microorganisms commonly involved for each syndrome, permitted the establishment of 31 incidental diagnoses.

Abstract
The clinical and epidemiological features of 56 patients with scalp eschar associated with neck lymphadenopathy after a tick bite (SENLAT) syndrome were evaluated at the National French Rickettsial Center. Eschar swabs, crusts, and biopsies as well as ticks and blood samples were acquired for molecular and serological assays. SENLAT predominantly affects children (p < 0.05), followed by 40- to 70-year-olds, and it is found mostly in women (p < 0.05). The seasonal distribution has two peaks: one in the spring (55%) and one in the autumn (30%). The etiological agent was identified in 18 cases, which include Rickettsia slovaca in 13 cases with incidences of two co-infections with Rickettsia raoultii and one case caused by Rickettsia sibirica mongolitimonae. Other possible agents that were found in attached ticks were Candidatus R. rioja, Coxiella burnetii, and Borrelia burgdorferi. The tick vector was Dermacentor marginatus in almost all cases, with the exception of one case, in which Ixodes ricinus was identified as the vector. Our findings show that SENLAT is a clinical entity characterized as a local infection controlled by the immune system and is neither pathogen- nor vector-specific.

Abstract
Gut microbiota consists of 10(10) bacteria per gram of stool. Many antibiotic regimens induce a reduction in both the diversity and the abundance of the gut flora. We analyzed one stool sample collected from a patient treated for drug-resistant Mycobacterium tuberculosis and who ultimately died from pneumonia due to a Streptococcus pneumoniae 10 months later. We performed microscopic observation, used 70 culture conditions (microbial culturomics) with identification by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF) and 16S rRNA amplification and sequencing, pyrosequencing, and 18S rRNA amplification and clone sequencing. Electron and optical microscopic observations revealed the presence of yeast, but no bacterial species were observed. By culture, only 39 bacterial species were identified, including one new species, as well as three species that have not been previously observed in the human gut. The pyrosequencing showed only 18 phylotypes, detecting a lower number of bacterial species than the culture techniques. Only two phylotypes overlapped with culturomics. In contrast, an amount of chloroplasts was found. Additionally, specific molecular eukaryote detection found three fungal species. We recovered, for the first time, more cultivable than non-cultivable bacterial species in a patient with a low bacterial load in the gut, demonstrating the depth bias of pyrosequencing. We propose that the desertification of gut microbiota in this patient is a reflection of the total body microbiota and may have contributed to the invasive infection of S. pneumoniae. This finding suggests that caution should be applied when treating patients with broad-spectrum antibiotics, and preventive measures should be taken in order to avoid invasive infection.

Abstract
OBJECTIVE Several randomized trials have suggested recently that epidural steroid injections may not be a valid treatment in common low back pain and sciatica. To clarify this issue, we conducted a critical appraisal of relevant randomized trials published up to 1997. Attention was directed to methodological quality, results, and clinical implications. METHOD A Medline search identified 13 trials published between 1966 and 1997. Trial methodology was evaluated using a 100-point grid based on four groups of items, namely study population, therapeutic intervention, evaluation method, and data presentation and analysis. RESULTS Methodology quality scores ranged from 12 to 84 and were unrelated to the results of epidural steroid therapy. Five trials demonstrated greater pain relief within the first month in the steroid group as compared to the control group. Eight trials found no measurable benefits. Obstacles to meaningful comparisons across studies included differences in the patient populations, steroid used, volume injected, and number of injections. None of the published studies used the injection modalities that are standard practice in France. CONCLUSION Whether epidural steroids are effective in common low back pain and sciatica cannot be determined based on our review.
