G Grine, M A Boualam, M Drancourt
Methanobrevibacter smithii is the main human methanogen almost always found in the digestive tract of adults. Yet, the age at which M. smithii establishes itself as part of the developing intestinal microflora remains unknown. In order to gain insight into this, we developed a polyphasic approach, including microscopic observation by fluorescence in situ hybridisation, polymerase chain reaction (PCR) sequencing detection, identification and culture, to isolate and genotype M. smithii in one-day-old newborns' gastric juice specimens...

In Iran, patients showing rifampicin (RIF) resistance detected by the Xpert® MTB/RIF assay are considered as candidates for multidrug-resistant tuberculosis (MDR-TB) treatment. Despite the fact that RIF resistance has been used as a proxy for MDR-TB, little is known about the proportion of isoniazid (INH) resistance patterns in RIF-resistant TB. We systematically searched MEDLINE, Embase, and other databases up to March 2017 for studies addressing the proportion of INH resistance patterns in RIF-resistant TB in Iran...

Microbiota refers to a colony of microorganisms, and they are found in all multicellular organisms. This colony plays a major role in both the physiology and disease of the organism it inhabits. Much attention has been paid to host-microbiota interactions, but there has been little investigation on its role in carcinogenesis. In this study, we characterized a fecal mycobiota, also known as fungal signature, for the first time with 131 subjects, comprising polyp and colorectal cancer (CRC) patients, as well as a healthy control population...

REVIEW
B A Cunha, J Baron, C B Cunha
Doxycycline and, to a lesser extent, minocycline, have been used for decades to treat various serious systemic infections, but many physicians remain unfamiliar with their spectrum, interpretation of susceptibility results, pharmacokinetic/pharmacodynamic (PK/PD) properties, optimal dosing regimens, and their activity against MRSA, VRE, and multidrug-resistant (MDR) Gram-negative bacilli, e.g., Acinetobacter sp. This article reviews the optimal use of doxycycline and minocycline to treat a variety of infections and when minocycline is preferred instead of doxycycline...

Calprotectin and lactoferrin are released by the gastrointestinal tract in response to infection and mucosal inflammation. Our objective was to assess the usefulness of quantifying faecal lactoferrin and calprotectin concentrations in Clostridium difficile infection (CDI) patients with or without free toxins in the stools. We conducted a single-centre 22-month case-control study. Patients with a positive CDI diagnosis were compared to two control groups: group 1 = diarrhoeic patients negative for C. difficile and matched (1:1) to CDI cases on the ward location and age, and group 2 = diarrhoeic patients colonised with a non-toxigenic strain of C...

Previous studies have shown controversial results of factors associated with short-term mortality in patients with extended-spectrum beta-lactamase (ESBL)-producing E. coli bacteremia and no research has investigated the impact of the geriatric assessment criteria on short-term mortality. Our objective was to determine whether dementia and walking ability are associated with 30-day mortality in patients with ESBL-producing E. coli bacteremia. All blood bottle cultures, analyzed from January 2008 to April 2015, in the Bacteriology Department of a 2,600-bed, university-affiliated center, Nantes, France, were retrospectively extracted...

REVIEW
S Esposito, N Principi
Knowledge of whether and how respiratory microbiota composition can prime the immune system and provide colonisation resistance, limiting consecutive pathobiont overgrowth and infections, is essential to improving the prevention and therapy of respiratory disorders. Modulation of dysbiotic ecosystems or reconstitution of missing microbes might be a possible measure to reduce respiratory diseases. The aim of this review is to analyse the role of nasopharyngeal microbiota in the development of respiratory tract disease in paediatric-age subjects...

Transplant recipients are at high risk of cytomegalovirus (CMV) infection. Mechanisms explaining the variation in risk of infections are far from fully elucidated. We hypothesised that host genetics explains part of the variation in risk of infection and examined if relatives of recipients with CMV infection have higher rates of severe infections compared to relatives of recipients without this infectious phenotype. In a register-based study, we included first-degree relatives of transplant recipients and examined the risk of hospitalisation due to overall infection or viral infection and risk of death among relatives of recipients who developed CMV infection within the first year of transplantation compared to relatives of recipients without CMV...

Trillions of microbes inhabiting the intestine form a complex ecological community, affecting the normal physiology and pathological susceptibility through their collective metabolic activities and interactions with the host. Increased numbers of diseases have been found to be associated with disturbances in this ecosystem. There is evidence that intestinal microflora undergoes alterations in patients with irritable bowel syndrome (IBS). IBS is a frequent functional gut disease with negative impact on the patient's quality of life...

Some strains of Clostridium difficile produce a binary toxin, in addition to the main C. difficile virulence factors (toxins A and B). There have been conflicting reports regarding the role of binary toxin and its relationship to the severity of C. difficile infection (CDI). Samples, isolates and clinical data were collected as part of a prospective multicentre diagnostic study. Clostridium difficile isolates (n = 1259) were tested by polymerase chain reaction (PCR) assay to detect binary toxin genes cdtA and cdtB...

In India, dengue endemic areas overlap with chikungunya-affected areas and both the viruses are transmitted by same vector, Aedes aegypti - thereby increasing opportunity of co-infection by both viruses. Present study was carried out to understand the DENV-CHIKV infection dynamics during recent outbreaks in eastern India (West Bengal state) and its implication on disease manifestations. Blood was collected from 326 symptomatic febrile patients. Patients' serum was subjected to serological diagnosis for presence of anti-dengue-IgM, anti-chikungunya-IgM antibodies and dengue-NS1 antigen by ELISA...

REVIEW
Z Xu, J Li, H Wang, G Xu
For many years, the coexistence of Helicobacter pylori (H. pylori) infection and atherosclerotic diseases in a disproportional number of patients has inspired the presumption that a causal relationship exists between the conditions. This presumption was evidenced by the simultaneously declining epidemics of duodenal ulcer and coronary artery diseases in the United States in the past 40 years, and was further evidenced by the detection of H. pylori and their DNA in atherosclerotic plaques. Suggested mechanisms underlying this possible causality include intensified inflammatory stress, dyslipidemia, abnormal glucose metabolism, arterial stiffness, increased blood pressure and malnutrition...

The novel siderophore cephalosporin cefiderocol (S-649266) with potent activity against Gram-negative pathogens was recently developed (Shionogi & Co., Ltd.). Here, we evaluated the activity of this new molecule and comparators against a collection of previously characterized Gram-negative isolates using broth microdilution panels. A total of 753 clinical multidrug-resistant Gram-negative isolates collected from hospitals worldwide were tested against cefiderocol and antibiotic comparators (ceftolozane-tazobactam [CT], meropenem [MEM], ceftazidime [CAZ], ceftazidime-avibactam [CZA], colistin [CST], aztreonam [ATM], amikacin [AMK], ciprofloxacin [CIP], cefepime [FEP], and tigecycline [TGC]) for their susceptibility...

The diagnosis of Lyme borreliosis is challenging because of the often non-specific symptoms and persisting antibodies after infection. We investigated the diagnostic characteristics of two enzyme-linked immunosorbent assays (ELISAs) and an immunoblot for the detection of Borrelia-specific serum antibodies using different test strategies in individuals with and without antibiotic treatment for Lyme borreliosis. This retrospective study included healthy individuals, patients with active Lyme neuroborreliosis and patients treated for Lyme neuroborreliosis...
