Characterization of spiny lobsters from Bangladesh waters using morphology, COI and 16S rRNA sequences

open access: yesHeliyon, 2022
This study aims to taxonomically identify and characterise the phylogenetic relationships of spiny lobsters based on mitochondrial cytochrome c oxidase I (COI) and 16S rRNA genes from Bangladesh waters.

Paenibacillus brasilensis sp nov., a novel nitrogen-fixing species isolated from the maize rhizosphere in Brazil [PDF]

open access: yes, 2002
Sixteen nitrogen-fixing strains isolated from the rhizosphere of maize planted in Cerrado soil, Brazil, which showed morphological and biochemical characteristics similar to the gas-forming Paenibacillus spp., were phenotypically and genetically ...

Activity profiles for marine sponge-associated bacteria obtained by 16S rRNA vs 16S rRNA gene comparisons [PDF]

open access: yesThe ISME Journal, 2010
Abstract The phylogenetic diversity of microorganisms in marine sponges is becoming increasingly well described, yet relatively little is known about the activities of these symbionts. Given the seemingly favourable environment provided to microbes by their sponge hosts, as indicated by the extraordinarily high abundance of sponge ...

Choice of 16S Ribosomal RNA Primers Impacts Male Urinary Microbiota Profiling

open access: yesFrontiers in Cellular and Infection Microbiology, 2022
Accessibility to next-generation sequencing (NGS) technologies has enabled the profiling of microbial communities living in distinct habitats. 16S ribosomal RNA (rRNA) gene sequencing is widely used for microbiota profiling with NGS technologies.

Louse (Insecta : Phthiraptera) mitochondrial 12S rRNA secondary structure is highly variable [PDF]

open access: yes, 2002
Lice are ectoparasitic insects hosted by birds and mammals. Mitochondrial 12S rRNA sequences obtained from lice show considerable length variation and are very difficult to align.

Taxonomy of the canine Mollicutes by 16S rRNA gene and 16S/23S rRNA intergenic spacer region sequence comparison [PDF]

open access: yesInternational Journal of Systematic and Evolutionary Microbiology, 2004
The taxonomy of canine Mollicutes is described, based on phylogenetic analysis of 16S rRNA gene and 16S/23S rRNA intergenic spacer (IGS) region sequences. The nucleotide sequences of the 16S rRNA gene of two untyped mycoplasmas and the IGS region of 11 Mycoplasma species were determined and used for phylogenetic analysis.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

PHYLOGENETIC ANALYSIS OF BACTERIAL COMMUNITIES IN PANCURAN 7 BATURRADEN HOT SPRING [PDF]

open access: yes, 2006
The diversity of the bacterial communities supported by culturing and capturing through 0.2 m-pore-size filter was studied. The Pancuran 7 hot spring has temperature at around 52°C and pH 7.

Translophagy—A potential link between autophagy impairment and translational errors

open access: yesFEBS Letters, EarlyView.
Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

Amplicon Sequence Variants Artificially Split Bacterial Genomes into Separate Clusters

open access: yesmSphere, 2021
16S rRNA gene sequencing has engendered significant interest in studying microbial communities. There has been tension between trying to classify 16S rRNA gene sequences to increasingly lower taxonomic levels and the reality that those levels were ...
