Abstract
Nociceptive hypersensitivity is a significant side effect with the chronic administration of opioids as well as chemotherapeutics. Both opioid-induced hypersensitivity (OIH) and chemotherapy-induced hypersensitivity (CIH) are characterized by an increased sensitivity to painful stimuli which can significantly reduce the quality of life for individuals on either drug(s). Here we demonstrate the nociceptive hypersensitivity associated with repeated administration of morphine (opioid) and paclitaxel (chemotherapeutic) treatment can be reversed by oral supplementation with the short-chain fatty acid (SCFA) sodium butyrate (NaBut). In two separate mouse behavioral models for nociceptive hypersensitivity, we found that thermal hyperalgesia (for OIH) and cold allodynia (for CIH) were prevented by treatment with oral butyrate (p.o, b.i.d). Electrophysiological recordings of small diameter dorsal root ganglia (DRG) neurons from morphine and paclitaxel treated mice showed an increase in neuronal hyperexcitability in both drug models which was likewise prevented by oral butyrate treatment. Using colonic conditioned media obtained from excised colon segments we found that gut mediators of morphine treated mice can induce hyperexcitability in naïve DRG neurons, but such enhanced excitability is not present when animals are co-treated with NaBut suggesting gut derived mediators modulate neuronal hyperexcitability. In-vitro NaBut treatment did not prevent morphine-induced excitability, suggesting an indirect role of butyrate in modulating neuronal hypersensitivity. These data taken together suggest that gut derived mediators affect opioid and chemotherapeutic-induced neuronal hypersensitivity that is prevented by the SCFA butyrate.

Abstract
Peripheral hypersensitivity is a significant side effect with the chronic administration of opioids as well as chemotherapeutics. Both opioid-induced hypersensitivity (OIH) and chemotherapy induced hypersensitivity (CIH) are characterized by an increased sensitivity to painful stimuli which can significantly reduce the quality of life for individuals on either drug(s). Here we demonstrate the peripheral hypersensitivity associated with chronic morphine (opioid) and paclitaxel (chemotherapeutic) treatment can be reversed by oral supplementation with the short-chain fatty acid (SCFA) sodium butyrate. In two separate mouse behavioral models for peripheral hypersensitivity, we found that thermal hyperalgesia (for OIH) and cold allodynia (for CIH) were prevented by co-treatment with oral butyrate. Electrophysiological recordings of small diameter dorsal root ganglia (DRG) neurons from morphine and paclitaxel treated mice showed an increase in neuronal hyperexcitability in both drug models which was likewise prevented by oral butyrate treatment.

Abstract
In this study, the digestion and fermentation properties of a bioactive polysaccharide (MOP-2) purified from Moringa oleifera leaves and its impact on the human colonic microbiota were determined using simulated saliva-gastrointestinal digestion and human fecal fermentation models in vitro. The results showed that the simulated saliva and gastric juices had no effect on the average molecular weight (MW) of MOP-2. The MW of MOP-2 slightly decreased from 155.29 to 145.02 kDa during intestinal digestion, and the reducing sugar content increased from 0.159 to 0.234 mg/ml, indicating that MOP-2 was partially degraded during intestinal digestion. During fermentation, MOP-2 was largely used by human fecal inoculums. Notably, MOP-2 could significantly regulate the structure of the microbial community by improving the relative abundances of some beneficial gut microbiota, such as Phascolarctobacterium, Coprococcus, Roseburia, and Bacteroides. Additionally, after fermentation for 48 hr, MOP-2 could significantly improve the production of short-chain fatty acids, especially n-butyric acid, acetic acid, propionic acid, and n-valeric acid. These results suggested that MOP-2 could potentially be a gut microbiota manipulator aimed at promoting gut health. PRACTICAL APPLICATIONS: Gut microbial community is an important part of the human intestinal environment. The health of gut microbiota is closely associated with host heath. This work reported that a polysaccharide (MOP-2) purified from Moringa oleifera leaves could modulate the microbial structure by improving the relative abundances of some beneficial gut microbiota, which provided useful information for the application of MOP-2 as a prebiotic additive in food industry.

Abstract
crAss-like viruses are a putative family of bacteriophages recently discovered. The eponym of the clade, crAssphage, is an enteric bacteriophage estimated to be present in at least half of the human population and it constitutes up to 90% of the sequences in some human fecal viral metagenomic datasets. We focused on the evolutionary dynamics of the genes encoded on the crAssphage genome. By investigating the conservation of the genes, a consistent variation in the evolutionary rates across the different functional groups was found. Gene duplications in crAss-like genomes were detected. By exploring the differences among the functional categories of the genes, we confirmed that the genes encoding capsid proteins were the most ubiquitous, despite their overall low sequence conservation. It was possible to identify a core of proteins whose evolutionary trees strongly correlate with each other, suggesting their genetic interaction. This group includes the capsid proteins, which are thus established as extremely suitable for rebuilding the phylogenetic tree of this viral clade. A negative correlation between the ubiquity and the conservation of viral protein sequences was shown. Together, this study provides an in-depth picture of the evolution of different genes in crAss-like viruses.

Abstract
We are in the midst of “the microbiome revolution”—not a day goes by without some new revelation on the potential role of the gut microbiome in some disease or disorder. From an ever-increasing recognition of the many roles of the gut microbiome in health and disease comes the expectation that its modulation could treat or prevent these very same diseases. A variety of interventions could, at least in theory, be employed to alter the composition or functional capacity of the microbiome, ranging from diet to fecal microbiota transplantation (FMT). For some, such as antibiotics, prebiotics, and probiotics, an extensive, albeit far from consistent, literature already exists; for others, such as other dietary supplements and FMT, high-quality clinical studies are still relatively few in number. Not surprisingly, researchers have turned to the microbiome itself as a source for new entities that could be used therapeutically to manipulate the microbiome; for example, some probiotic strains currently in use were sourced from the gastrointestinal tract of healthy humans. From all of the extant studies of interventions targeted at the gut microbiome, a number of important themes have emerged. First, with relatively few exceptions, we are still a long way from a precise definition of the role of the gut microbiome in many of the diseases where a disturbed microbiome has been described—association does not prove causation. Second, while animal models can provide fascinating insights into microbiota–host interactions, they rarely recapitulate the complete human phenotype. Third, studies of several interventions have been difficult to interpret because of variations in study population, test product, and outcome measures, not to mention limitations in study design. The goal of microbiome modulation is a laudable one, but we need to define our targets, refine our interventions, and agree on outcomes.

Abstract
PURPOSE OF REVIEW The infectious complications of transplantation can have devastating consequences for patients. Early and accurate diagnosis is essential to good outcomes. This review describes recent advances in pathogen-directed diagnostic testing and discusses the role of new methods for transplant infectious diseases. RECENT FINDINGS Several molecular assays have been introduced into clinical practice in recent years. When the results of rapid testing are linked to patient-specific interventions, improved outcomes can be realized. Syndromic testing along with metagenomic next-generation sequencing (mNGS) represents novel approaches to infection diagnosis. However, the optimal use of these tests for transplant patients along with an overall assessment of cost-effectiveness demands further study. Molecular diagnostics are revolutionizing transplant care. Clinicians need to be aware of the current diagnostic landscape and have a working knowledge of the nuances related to test performance, result interpretation, and cost.

Abstract
Role of gut microbiome in obesity and type 2 diabetes (T2D) became apparent from several independent studies indicating that gut microbiome modulators like prebiotics may improve microbiome perturbations (dysbiosis) to ameliorate metabolic derangements. We herein isolate water soluble, nondigestible polysaccharides from five plant-based foods (acorn, quinoa, sunflower, pumpkin seeds and sago) and assess their impact on human fecal microbiome and amelioration of high-fat-diet (HFD)-induced obesity/T2D in mice. During polysaccharide isolation, purification, biochemical and digestion resistance characterization, and fermentation pattern by human fecal microbiome, we select acorn- and sago-derived prebiotics (on the basis of relatively higher purity and yield and lower protein contamination) and examine their effects in comparison to inulin. Prebiotics treatments in human fecal microbiome culture system not only preserve microbial diversity but also appear to foster beneficial bacteria and short-chain fatty acids (SCFAs). Feeding of acorn- and sago-derived prebiotics ameliorates HFD-induced glucose intolerance and insulin resistance in mice, with effects comparatively superior to those seen in inulin-fed mice. Feeding of both of novel prebiotics as well as inulin increases SCFAs levels in the mouse gut. Interestingly, gut hyperpermeability and mucosal inflammatory markers were significantly reduced upon prebiotics feeding in HFD-fed mice. Hypothalamic energy signaling in terms of increased expression of pro-opiomelanocortin was also modulated by prebiotics administration. Results demonstrate that these (and/or such) novel prebiotics can ameliorate HFD-induced defects in glucose metabolism via positive modulation of gut-microbiome-brain axis and hence could be useful in preventing/treating diet-induced obesity/T2D.

Abstract
As the importance of the gut microbiota in health and disease is increasingly recognized interest in interventions that can modulate the microbiota and its interactions with its host has soared. Apart from diet, prebiotics and probiotics represent the most commonly used substances taken in an effort to sustain a healthy microbiome or restore balance when it is believed bacterial homeostasis has been disturbed in disease. While a considerable volume of basic science attests to the ability of various prebiotic molecules and probiotic strains to beneficially influence host immune responses, metabolic processes and neuro-endocrine pathways, the evidence base from human studies leaves much to be desired. This translational gap owes much to the manner in which this sector is regulated but also speaks to the challenges that confront the investigator who seeks to explore microbiota modulation in either healthy populations or those who suffer from common digestive ailments. For many products marketed as probiotics, some of the most fundamental issues relating to quality control, such as characterization, formulation, viability safety are scarcely addressed.

The Lactobacillus Bile Salt Hydrolase Repertoire Reveals Niche-Specific Adaptation. mSphere 2018; 3:3/3/e00140-18.

Abstract
Various Lactobacillus species have been reported to deconjugate bile acids in the gastrointestinal tract (GIT) through the action of bile salt hydrolase (BSH) proteins. This function contributes to altering the gut microbiota composition and bile metabolism and detoxification and to lowering cholesterol levels. Here, we investigated the Lactobacillus BSH repertoire across 170 sequenced species. We used hidden Markov models to distinguish between BSH and closely related penicillin-V acylase (PVA) proteins. Even though BSH and PVA proteins have very different target substrates, they share high sequence similarity and are often misannotated. We determined that 82/170 (48.24%) species encoded PVA proteins, 39/170 (22.94%) species encoded BSH proteins, and 8/170 (4.71%) species encoded both BSH and PVA proteins, while 57/170 (33.53%) species encoded neither. Mapping the occurrence of BSH-encoding species onto a phylogenetic tree revealed that BSH-encoding lactobacilli primarily adopt the vertebrate-adapted lifestyle but not the environmental or plant-associated subsets. Phylogenetic analysis of the BSH sequences revealed two distinct clades, several conserved motifs, and the presence of six previously reported active-site residues. These data will guide future mechanistic studies of BSH activity and contribute to the development and selection of BSH-encoding Lactobacillus strains with therapeutic potential.IMPORTANCE Bile acids play an integral role in shaping the gut microbiota and host physiology by regulating metabolic signaling, weight gain, and serum cholesterol and liver triglyceride levels. Given these important roles of bile acids, we investigated the presence of bile salt hydrolase (BSH) in Lactobacillus genomes representing 170 different species, determined strain- and species-specific patterns of occurrences, and expanded on the diversity of the BSH repertoire in this genus. While our data showed that 28% of Lactobacillus species encode BSH proteins, these species are associated mainly with vertebrate-adapted niches, demonstrating selective pressure on lactobacilli to evolve to adapt to specific environments. These new data will allow targeted selection of specific strains of lactobacilli and BSH proteins for future mechanistic studies to explore their therapeutic potential for treating metabolic disorders.
