The redbanded stink bug, Piezodorus guildinii (Westwood) (Hemiptera: Heteroptera: Pentatomidae), is a rapidly growing pest damaging southern US agriculture. Pentatomid stink bugs are known to vector bacterial, fungal, and viral plant diseases. However, bacteria associated with redbanded stink bugs and their vector potential have not yet been assessed. In this study, we 1) cultured and identified bacteria transmitted by feeding of redbanded stink bug and 2) described bacteria from guts of redbanded stink bug individuals using next-generation sequencing of 16S rRNA genes...

BACKGROUND: Necrotizing enterocolitis (NEC) is a devastating gastrointestinal disease with high morbidity and mortality that predominantly affects preterm neonates during outbreaks. In a previous study, the present authors identified 15 Clostridium butyricum isolates from stool samples during a series of NEC cases involving four neonatal intensive care units. A clonal lineage of these strains was observed by in-silico multi-locus sequence typing. AIM: To confirm the previous findings by sequencing a larger number of C...

The causes of periodontal disease are complex. Butyric acid, a metabolite of periodontopathic bacteria such as Porphyromonas gingivalis, acts as a histone deacetylase inhibitor that has a direct effect on mRNA expression. Butyric acid produced by Clostridium butyricum in the intestinal tract induces differentiation of regulatory T cells, thereby suppressing inflammation in the gut. Mice lacking Clostridium butyricum in the intestinal tract suffer from colitis. By contrast, butyric acid in the oral cavity worsens periodontal disease...

In a recent publication that attempts to deal with the growing problem of taxa being added to the genus Clostridium that are outside of Clostridium (16S rRNA) group I, a solution is proposed that seeks to limit the genus Clostridium Prazmowski 1880 (Approved Lists 1980) to a small number of species 'related' to the type species, Clostridium butyricum Prazmowski 1880 (Approved Lists 1980). It has been proposed that this genus should also include members of the genus Sarcina Goodsir 1842 (Approved Lists 1980), Sarcinamaxima Lindner 1888 (Approved Lists 1980) and Sarcinaventriculi Goodsir 1842 (Approved Lists 1980), the latter being the nomenclatural type of the genus Sarcina Goodsir 1842 (Approved Lists 1980)...

Clostridium tyrobutyricum is the main microorganism responsible for the late blowing defect in hard and semi-hard cheeses, causing considerable economic losses to the cheese industry. Deeper knowledge of the metabolic requirements of this microorganism can lead to the development of more effective control approaches. In this work, the amino acids and B vitamins essential for sustaining the growth of C. tyrobutyricum were investigated using a genomic approach. As the first step, the genomes of four C. tyrobutyricum strains were analyzed for the presence of genes putatively involved in the biosynthesis of amino acids and B vitamins...

The recent proposal by Lawson and Rainey (2015) to restrict the genus Clostridium to Clostridium butyricum and related species has ramifications for the members of the genera that fall outside this clade that should not be considered as Clostridium sensu stricto. One such organism of profound medical importance is Clostridioides difficile that is a major cause of hospital-acquired diarrhea and mortality in individuals. Based on 16S rRNA gene sequence analysis, the closest relative of Clostridium difficile is Clostridium mangenotii with a 94...

Glycyl radical enzymes (GREs) represent a diverse superfamily of enzymes that utilize a radical mechanism to catalyze difficult, but often essential, chemical reactions. In this work we present the first biochemical and structural data for a GRE-type diol dehydratase from the organism Roseburia inulinivorans (RiDD). Despite high sequence (48% identity) and structural similarity to the GRE-type glycerol dehydratase from Clostridium butyricum, we demonstrate that the RiDD is in fact a diol dehydratase. In addition, the RiDD will utilize both (S)-1,2-propanediol and (R)-1,2-propanediol as a substrate, with an observed preference for the S enantiomer...

To improve its 1,3-propanediol (1,3-PD) production, Clostridium butyricum was cultivated on glycerol medium supplemented with cassava pulp (CP). At small concentrations, the CP improved the 1,3-PD productivity of C. butyricum from (0.25±0.01)g/L/h (glycerol alone) to (0.43±0.02)g/L/h (glycerol+2g/L CP) after 24h fermentation.

The aberrant T cell activation plays an important role in the pathogenesis of intestinal inflammation, such as ulcerative colitis (UC). C. butyricum (Cb) is a probiotic and has been employed in the treatment of immune diseases. This study tests a hypothesis that specific immunotherapy (SIT) plus oral Cb (an over-the-counter probiotic) alleviates the UC symptoms. In this study, we conducted a randomized, double-blind, clinical study at our hospital. A total of 80 patients with relapsing-remitting ulcerative colitis and high levels of specific IgE antibody was randomly divided into 4 groups, and were treated with SIT or/and Cb, or placebo, respectively for 1 year...

Obesity is associated with a cluster of metabolic disorders and systemic low-grade inflammation involving multiple organs. Recent findings have suggested that intestine is a key organ altered in response to high fat diet (HFD) feeding. Probiotics mainly lactobacillus strains have earlier been implicated in alleviating metabolic disorders. Here we aimed to examine the effects of a naturally occurring butyrate-producing probiotic clostridium butyricum CGMCC0313.1 (CB0313.1) in limiting the development of HFD-induced obesity...
