Complete plastid genome (plastome) and ribosomal DNA (rDNA) sequences of three accessions (two and one ) were newly assembled using Illumina whole-genome sequences. Nakai and var. tozawai, described as different varieties, have identical plastomes and rDNA sequences. The plastomes are 155,957 bp and 156,005 bp and the 45S rDNA transcription unit sizes are 5809 bp and 5811 bp in and , respectively. The 5S rDNA transcription unit is an identical 121 bp in three accessions. We developed three DNA markers to authenticate and based on plastome diversity. Phylogenomic analysis revealed that the species classified as two clades and , , and are the most closely related species in clade 1.

Echinorhynchids are a group of globally distributed acanthocephalan parasites mainly of freshwater, brackish and marine fishes and occasionally, reptiles and amphibians. During several parasitology surveys in the Gulf of Mexico and Northeast Pacific, Mexico, acanthocephalans were recovered from two marine fish species. The specimens from the Gulf of Mexico were identified as Caballerorhynchus lamothei (Cavisomidae), a typical parasite of the striped mojarra, whereas adult acanthocephalans from the Northeast Pacific, Mexico, from the Garibaldi fish exhibited morphological characteristics belonging to the family Transvenidae.

Four Gram-stain-negative, strictly aerobic, catalase- and oxidase-positive bacterial strains, designated 2201CG5-10, 2201CG14-23, 2201CG1-2-11, and 2304DJ70-9 were isolated from marine sponges collected in the Republic of Korea. Phylogenetic analyses based on 16S rRNA gene and whole-genome sequences revealed that these strains represent a distinct phyletic lineage within the genus Aquimarina. Based on the whole-genome sequence comparisons, the closest phylogenetic relatives of the four novel strains were Aquimarina latercula DSM 2041, Aquimarina pacifica SW150, and Aquimarina mytili PSC33, which shared average nucleotide identity values below 81.

Objective: Patients with acute pancreatitis show reduced gut microbiome diversity and high abundance of pathogenic bacteria compared with healthy subjects. Admission microbiome profiles are increasingly linked to severity, but methodology and study quality hamper interpretation. Our aim was to investigate whether admission microbiome analysis provides robust and reproducible associations with severity and complications of acute pancreatitis.

Aquatic environmental pollution could be a direct trigger of infection through cercarial invasion to skin / gills or indirectly as a predisposing factor that damage the physical barriers of targeted fish resulting in high intensities of EMC infections in all fish vital organs. In the current study, a total of 150 African catfish (Clarias gariepinus) were randomly collected from Mariotteya drain all the way through the Egyptian township of Shabramant located at the historical heart of Giza. Catfish samples were collected in mid-summer during the period from June to July 2024.

Background: The damselfishes, an extremely diverse group of herbivorous fish, stands out as an important and ubiquitous ecological component of coral reefs. In the Western South Atlantic, the genus Stegastes is the most representative, whose evolutionary paths and taxonomic status of insular endemic species have been better evaluated. To clarify the karyotypic evolution involved in the diversification of this group, cytogenetic analyses were performed in four nominal species (S.
