[Investigation of the population diversity of intermediate host snails and crabs of along Jiulong River, Zhangjiang River and Dongxi River basins in southern Fujian Province].

Objective: To investigate the population distribution of intermediate host snails and crabs of along the Jiulongjiang River, Zhangjiang River, and Dongxi River basins in Bopingling Mountain, southern Fujian Province, so as to provide baseline data for researches on parasitic disease prevention and control and enlargement of samples in the parasitic resource bank.

Methods: A total of 23 villages in 8 counties (districts) along the Jiulong River, Zhangjiang River, and Dongxi River basins in Zhangzhou City, Fujian Province were selected as survey sites during the period from November 2020 through March 2023, and snail and freshwater crabs were sampled from 1 to 3 streams and ditches neighboring residential areas in each village. Morphological identification of snails was performed according to the external morphological characteristics of collected snail shells, and the unidentified snail species sampled from the natural foci of paragonimiasis in Yunxiao County were subjected to se-quence analysis of the mitochondrial cytochrome oxidase 1 () gene.

[Establishment of a fluorescent recombinase-aided isothermal amplification assay for nucleic acid detection of and preliminary evaluation of its detection efficiency].

Objective: To establish a nucleic acid assay for detection of based on the recombinase-aided isothermal amplification (RAA) technique, and to preliminarily evaluate its detection efficiency.

Methods: The metacercariae of , and were isolated from crabs, and genomic DNA was extracted for molecular characterization. The cytochrome coxidase 1 () gene sequence of was selected as the target gene fragment, and the primers and probes were designed, screened and synthesized for RAA assay.

Rapid and Visual Detection of in Aquatic Foods Using Gene-Based Loop-Mediated Isothermal Amplification with Lateral Flow Dipstick (LAMP-LFD).

is recognized as one of the most important foodborne pathogens responsible for gastroenteritis in humans. The gene is an intrinsic β-lactamase gene and a novel species-specific genetic marker of . In this study, a loop-mediated isothermal amplification (LAMP) assay combined with a lateral flow dipstick (LFD) was developed targeting this gene.

Isolation, Molecular Characterization and Antibiotic Susceptibility Pattern of from Aquatic Products in the Southern Fujian Coast, China.

is a major gastroenteritis-causing pathogen in many Asian countries. Antimicrobial resistance in has been recognized as a critical threat to food safety. In this study, we determined the prevalence and incidence of antimicrobial resistance in in the southern Fujian coast, China.
