Here, we report the draft genome sequences of Edwardsiella ictaluri strains LADL11-100 and LADL11-194, two isolates from natural outbreaks of edwardsiellosis in the zebrafish Danio rerio, as well as the sequences of the plasmids carried by the zebrafish strain of E. ictaluri.
Joint toxicity of arsenate and perchlorate was tested in larvae of Danio rerio. Results indicated that the 96-h median lethal concentrations of sodium arsenate and sodium perchlorate were 258.8 and 1,401.2 mg/L, respectively, and that arsenate and perchlorate generally showed a concentration-additive effect.
We have developed a bioinformatics pipeline for the comparative evolutionary analysis of Ensembl genomes and have used it to analyze the introns of the five available teleost fish genomes. We show our pipeline to be a powerful tool for revealing variation between genomes that may otherwise be overlooked with simple summary statistics. We identify that the zebrafish, Danio rerio, has an unusual ...
During embryonic development, a complex organism is formed from a single starting cell. These processes of growth and differentiation are driven by large transcriptional changes, which are following the expression and activity of transcription factors (TFs). This study sought to compare TF expression during embryonic development in a diverse group of metazoan animals: representatives of vertebr...
Melanopsin has been implicated in the mammalian photoentrainment by blue light. This photopigment, which maximally absorbs light at wavelengths between 470 and 480 nm depending on the species, is found in the retina of all classes of vertebrates so far studied. In mammals, melanopsin activation triggers a signaling pathway which resets the circadian clock in the suprachiasmatic nucleus (SCN). U...
Worldwide, pesticides have contaminated the environment, affecting non-target species. The aim of this work was to evaluate effects fosetyl-Al (FOS) on model organisms. Based 3 Rs for animal research and described guidelines, OECD 236 220 were applied with some modifications. FOS test concentrations 0.02–0.2–2–20–200 mg/L Danio rerio 250–500–750–1000–1250 mg/kg Enchytraeus crypticus. Besides st...
