House fly larvae provide a prolific and sustainable source of proteins used in poultry and fish feed. Wheat bran is a superior diet for house fly larvae and has been widely investigated to exploit its potential in the food and feed area. Using Illumina MiSeq 16S rDNA sequencing, this study investigated the gut microbiota of house fly larvae feeding on wheat bran and the bacterial community in the wheat bran. The bacterial communities in the house fly larvae were dominated by the phyla Proteobacteria and Firmicutes...

Aims: The additional benefit of a defibrillator in cardiac resynchronization therapy (CRT) patients is a matter of debate. Cause-of-death analysis in a CRT population has been recently proposed as a useful approach to gain insight into this problem. We performed a systematic review and meta-analysis looking at cause of death in studies involving CRT subjects with (CRT-D) or without (CRT-P) a defibrillator. Methods and results: Literature search performed from inception to 31 March 2016 for relevant studies...

It has become increasingly apparent within the last several years that unusual N-formylated sugars are often found on the O-antigens of such Gram negative pathogenic organisms as Francisella tularensis, Campylobacter jejuni, and Providencia alcalifaciens, among others. Indeed, in some species of Brucella, for example, the O-antigen contains 1,2-linked 4-formamido-4,6-dideoxy-α-d-mannosyl groups. These sugars, often referred to as N-formylperosamine, are synthesized in pathways initiating with GDP-mannose. One of the enzymes required for the production of N-formylperosamine, namely, WbkC, was first identified in 2000 and was suggested to function as an N-formyltransferase...

The Gram-negative bacterium Proteus mirabilis is a leading cause of catheter-associated urinary tract infections (CAUTIs), which are often polymicrobial. Numerous prior studies have uncovered virulence factors for P. mirabilis pathogenicity in a murine model of ascending UTI, but little is known concerning pathogenesis during CAUTI or polymicrobial infection. In this study, we utilized five pools of 10,000 transposon mutants each and transposon insertion-site sequencing (Tn-Seq) to identify the full arsenal of P...

Diverse antibiotic-resistance genes (ARGs) are frequently reported to have high prevalence in veterinary manure samples due to extensive use of antibiotics in farm animals. However, the characteristics of the distribution and transmission of ARGs among bacteria, especially among different species of multiple antibiotic-resistant bacteria (MARB), have not been well explored. By applying high-throughput sequencing methods, our study uncovered a vast MARB reservoir in livestock manure. The genera Escherichia, Myroides, Acinetobacter, Proteus, Ignatzschineria, Alcaligenes, Providencia and Enterococcus were the predominant cultivable MARB, with compositions of 40...

Epidemiologically unrelated Providencia stuartii strains isolated in hospitals in the south of France were investigated for their porin sequences and profiles. Noticeable resistance to β-lactams was found to be associated with production of extended spectrum β-lactamases or AmpC overproduction, but not metallo-β-lactamases. At the same time, the expression level of outer membrane porins was unmodified in these isolates. The identity of the amino acid sequences of the major porin OmpPst1 was less than 90% in the tested clinical strains, whereas sequences of the second major porin OmpPst2 were found to be identical in all isolates...

Preoperative progressive pneumoperitoneum and botulinum toxin type A are useful tools in the preparation of patients with loss of domain hernias. Both procedures are complementary in the surgical repair, especially with the use of prosthetic techniques without tension, that allow a integral management of these patients. The aim of this paper is to update concepts related to both procedures, emphasizing the advantages that take place in the preoperative management of loss of domain hernias.

Aims: Cardiac sarcoidosis (CS) is associated with a poor prognosis. Important features of CS include heart failure, conduction abnormalities, and ventricular arrhythmias. Ventricular tachycardia (VT) is often refractory to antiarrhythmic drugs (AAD) and immunosuppression. Catheter ablation has emerged as a treatment option for recurrent VT. However, data on the efficacy and outcomes of VT ablation in this context are sparse. Methods and results: A systematic search was performed on PubMed, EMBASE, and Cochrane database (from inception to September 2016) with included studies providing a minimum of information on CS patients undergoing VT ablation: age, gender, VT cycle length, CS diagnosis criteria, and baseline medications...
