Ecology and Evolutionary Biology of Hindering Phage Therapy: The Phage Tolerance vs. Phage Resistance of Bacterial Biofilms

open access: yesAntibiotics, 2023
As with antibiotics, we can differentiate various acquired mechanisms of bacteria-mediated inhibition of the action of bacterial viruses (phages or bacteriophages) into ones of tolerance vs. resistance.

Development of Nanoparticle Adaptation Phenomena in Acinetobacter baumannii: Physiological Change and Defense Response

open access: yesMicrobiology Spectrum, 2023
The present work describes the evolution of a resistance phenotype to a multitargeting antimicrobial agent, namely, silver nanoparticles (nanosilver; NAg), in the globally prevalent bacterial pathogen Acinetobacter baumannii.

Regulation of Immune Homeostasis via Muramyl Peptides-Low Molecular Weight Bioregulators of Bacterial Origin

open access: yesMicroorganisms, 2022
Metabolites and fragments of bacterial cells play an important role in the formation of immune homeostasis. Formed in the course of evolution, symbiotic relationships between microorganisms and a macroorganism are manifested, in particular, in the ...

The Role of microRNAs in Pulp Inflammation

open access: yesCells, 2021
The dental pulp can be affected by thermal, physical, chemical, and bacterial phenomena that stimulate the inflammatory response. The pulp tissue produces an immunological, cellular, and vascular reaction in an attempt to defend itself and resolve the ...

Phage Therapy: Eco-Physiological Pharmacology

open access: yesScientifica, 2014
Bacterial virus use as antibacterial agents, in the guise of what is commonly known as phage therapy, is an inherently physiological, ecological, and also pharmacological process.

Royal Decree: Gene Expression in Trans-Generationally Immune Primed Bumblebee Workers Mimics a Primary Immune Response. [PDF]

open access: yesPLoS ONE, 2016
Invertebrates lack the cellular and physiological machinery of the adaptive immune system, but show specificity in their immune response and immune priming. Functionally, immune priming is comparable to immune memory in vertebrates. Individuals that have

Shaping of microbial phenotypes by trade-offs

open access: yesNature Communications
Growth rate maximization is an important fitness strategy for microbes. However, the wide distribution of slow-growing oligotrophic microbes in ecosystems suggests that rapid growth is often not favored across ecological environments.

Features, roles and chiral analyses of proteinogenic amino acids

open access: yesAIMS Molecular Science, 2020
Amino acids (AAs) are important biomolecules responsible for plethora of functions in both prokaryotic and eukaryotic systems. There are 22 naturally occurring amino acids, among which 20 common amino acids appear in the genetic code and known as ...

Generation of transchromosomic mice harboring HLA-A/B/C and human B2M via mouse artificial chromosome and triple BAC integration

open access: yesScientific Reports
Humanized transgenic mice carrying human genes are useful for research on gene function and disease. Bacterial artificial chromosomes (BACs) that carry human genomic sequences with regulatory elements enable the expression of transgenes at physiological ...

The characteristics of actinomyces strptomyces griseorubiginosus 83 – the effective biosorbent of silver [PDF]

open access: yesE3S Web of Conferences, 2023
The bacteria bound about the same amount of silver at the time of inoculation and when added after 24 hours Fourier transform infrared spectroscopy (FT-IR) and measurements of the ζ- potential showed that several groups, mainly carboxy groups are ...
