Phenylketonuria Diet Promotes Shifts in Firmicutes Populations [PDF]

Frontiers in Cellular and Infection Microbiology, 2019
Low-phenylalanine diet, the mainstay of treatment for phenylketonuria (PKU), has been shown to increase glycemic index and glycemic load, affecting the availability of substrates for microbial fermentation.

Under-detection of endospore-forming Firmicutes in metagenomic data [PDF]

Computational and Structural Biotechnology Journal, 2015
Microbial diversity studies based on metagenomic sequencing have greatly enhanced our knowledge of the microbial world. However, one caveat is the fact that not all microorganisms are equally well detected, questioning the universality of this approach ...

Cryptosporulation in Kurthia spp. forces a rethinking of asporogenesis in Firmicutes [PDF]

Environmental Microbiology, 2022
Abstract Endosporulation is a complex morphophysiological process resulting in a more resistant cellular structure that is produced within the mother cell and is called endospore. Endosporulation evolved in the common ancestor of Firmicutes, but it is lost in descendant lineages classified as ...

Veillonella, Firmicutes: Microbes disguised as Gram negatives

Standards in Genomic Sciences, 2013
The Firmicutes represent a major component of the intestinal microflora. The intestinal Firmicutes are a large, diverse group of organisms, many of which are poorly characterized due to their anaerobic growth requirements. Although most Firmicutes are Gram positive, members of the class Negativicutes, including the genus Veillonella, stain Gram ...

Reconstruction of xylose utilization pathway and regulons in Firmicutes [PDF]

BMC Genomics, 2010
Abstract Background Many Firmicutes bacteria, including solvent-producing clostridia such as Clostridium acetobutylicum, are able to utilize xylose, an abundant carbon source in nature. Nevertheless, homology searches failed to recognize all the genes for the complete xylose and xyloside utilization pathway in most of

The Firmicutes/Bacteroidetes Ratio as a Risk Factor of Breast Cancer

Journal of Clinical Medicine, 2023
The gut microbiome can reflect the health condition of the entire body. Firmicutes and Bacteroidetes, the major phyla of the colon, can influence diseases related to obesity which are also risk factors for breast cancer. Therefore, the Firmicutes/Bacteroidetes (F/B) ratio was analyzed in patients with breast cancer.

Discovery of a new family of relaxases in Firmicutes bacteria [PDF]

PLOS Genetics, 2017
Antibiotic resistance is a serious global problem. Antibiotic resistance genes (ARG), which are widespread in environmental bacteria, can be transferred to pathogenic bacteria via horizontal gene transfer (HGT). Gut microbiomes are especially apt for the emergence and dissemination of ARG.

Plasmid-Mediated Antimicrobial Resistance in Staphylococci and Other Firmicutes

Microbiology Spectrum, 2014
ABSTRACT In staphylococci and other Firmicutes , resistance to numerous classes of antimicrobial agents, which are commonly used in human and veterinary medicine, is mediated by genes that are associated with mobile genetic elements.

Inhibition of Bacteroidetes and Firmicutes by select phytochemicals [PDF]

Anaerobe, 2020
Current research indicates that changes in gut microbiota can impact the host, but it is not always clear how dietary and environmental factors alter gut microbiota. One potential factor is antimicrobial activity of compounds ingested by the host. The goal of this study was to determine the antimicrobial activity of common plant secondary metabolites ...
