DNA repair mechanisms in eukaryotes: Special focus in Entamoeba histolytica and related protozoan parasites

open access: yesInfection, Genetics and Evolution, 2009
Eukaryotic cell viability highly relies on genome stability and DNA integrity maintenance. The cellular response to DNA damage mainly consists of six biological conserved pathways known as homologous recombination repair (HRR), non-homologous end-joining (NHEJ), base excision repair (BER), mismatch repair (MMR), nucleotide excision repair (NER), and ...

The Future of Pathogen Detection in Aquaculture: Miniature Labs, Field‐Compatible Assays, environmental DNA and RNA, CRISPR and Metatranscriptomics

open access: yesAquaculture, Fish and Fisheries, Volume 5, Issue 3, June 2025.
ABSTRACT Inland recirculating aquaculture is a thriving food industry providing sustainable and locally sourced high‐quality protein. However, its expansion is accompanied by emerging challenges regarding the spread of pathogens and diseases. Detection and management of pathogens in aquaculture remain underdeveloped compared to other animal farming ...

Kinetoplast DNA‐aggregating proteins from the parasitic protozoan Crithidia fasciculata

open access: yesFEBS Letters, 1990
Proteins from C. fasciculata, which preferentially aggregate the parasite's AT‐rich mitochondrial (kinetoplast) DNA in vitro, are reported. The aggregation is non‐topological, non‐covalent, independent of Mg2+ and ATP, but much improved by spennidine. We discuss how these proteins might modulate the shape and size of the parasite's mitochondrial genome.

Position Effect Takes Precedence Over Target Sequence in Determination of Adenine Methylation Patterns in the Nuclear Genome of a Eukaryote, \u3cem\u3eTetrahymena thermophila\u3c/em\u3e [PDF]

open access: yes, 1998
Approximately 0.8% of the adenine residues in the macronuclear DNA of the ciliated protozoan Tetrahymena thermophila are modified to N6-methyladenine. DNA methylation is site specific and the pattern of methylation is constant between clonal cell lines ...

Cost‐Effective Nanosensor Solutions for Ultra‐Sensitive Detection of Metronidazole

open access: yesAnalytical Science Advances, Volume 6, Issue 1, June 2025.
ABSTRACT Metronidazole (MNZ) is a widely used imidazole antibiotic effective against bacterial and protozoal infections, including giardiasis, trichomoniasis, bacterial vaginosis, and antibiotic‐associated colitis. However, prolonged and excessive use of MNZ can lead to serious side effects, such as peripheral neuropathies, toxicity, and optic ...

Detection of enteric parasite DNA in household and bed dust samples: potential for infection transmission. [PDF]

open access: yes, 2020
BACKGROUND: Enteric parasites are transmitted in households but few studies have sampled inside households for parasites and none have used sensitive molecular methods.

Can Unicellular Organisms Sequester a Germline? The Yeast‐Germline Hypothesis

open access: yesBioEssays, Volume 47, Issue 6, June 2025.
Asymmetrical inheritance of template‐DNA and copy‐DNA strands during mitosis can reduce the number of mutant cells. This requires that cells continuing to divide inherit the “immortal” template‐DNA, while their daughter cells become quiescent and inherit copy‐DNA strands.

Description of a new actinosporean type from South African freshwater [PDF]

open access: yes, 2004
The 1st report on actinospores described these organisms as parasites related to myxosporeans. For a long time this group of parasites was believed to represent an independent taxonomic entity.

Native synthetic microbial communities enhance zha‐chili by boosting the fermentation capacity of indigenous microorganisms

open access: yesiMetaOmics, Volume 2, Issue 2, June 2025.
Traditional fermented foods in synthetic microbial communities (SynComs). We simulated the production of zha‐chili, a traditional fermented food, in the laboratory, intending to address the following questions: How are SynComs constructed, and what is the effect of inoculation with SynComs on the quality of zha‐chilli? How does inoculation with SynComs

Germ Line-Specific DNA Sequences are Present on All Five Micronuclear Chromosomes in \u3cem\u3eTetrahymena thermophila\u3c/em\u3e [PDF]

open access: yes, 1983
The development of the macronucleus from the zygotic micronucleus in the ciliated protozoan Tetrahymena spp. involves the elimination of specific DNA sequences (M. C. Yao and M. Gorovsky, Chromosoma 48:1-18 1974).
