The gene, encoding a lipid A phosphatease, is crucial for lipopolysaccharide (LPS) synthesis in Gram-negative bacteria and plays a critical role in their virulence. This study investigated the role of in , a significant marine pathogen causing gastroenteritis in humans and infections in aquatic animals. We constructed an deletion mutant (Δ) and a complementary strain (CΔ) using homologous recombination.

Vibrio anguillarum is a pathogen responsible for vibriosis in aquaculture animals. The formation of bacterial biofilm contributes to infections and increases resistance to antibiotics. Tryptophanase and its substrate tryptophan have been recognized as signal molecules regulating bacterial biofilm formation.

Article Synopsis
  • Scientists studied a bacteria called Vibrio parahaemolyticus that can make people and shrimp sick.
  • They focused on the hlyA and hlyIII genes, which help the bacteria to cause damage.
  • Tests showed that without these genes, the bacteria were much less harmful to both shrimp and other tiny creatures they were tested with.

Porins are crucial proteins located in the outer membrane that directly influence antimicrobial resistance mechanisms and virulence in bacteria. In this study, a porin gene () was cloned in , and the function of Vp-Porin in biological characteristics and virulence was investigated. The results of sequence analysis showed that Vp-Porin is highly conserved in spp.

Due to the significant sex dimorphism, Cynoglossus semilaevis has long been a species of research interest in the field of artificial sex manipulation. The existence of pseudo-males both in the natural habitat and aquaculture enterprises also is indicative of the importance for identification of the genetic sex in this species. In the present study, there was elucidation of a novel molecular marker for utilizing the recombinase aided amplification-lateral flow dipstick (RAA-LFD) visual system to identify the genetic sex of C.

Paralichthys olivaceus is the kind of cold-water benthic marine fish. In the early stages of development, the symmetrical juveniles transform into an asymmetrical body shape through metamorphosis for adapting benthic life. After that, one side of the fish body is attached to the ground, and the eyes turn to the opposite side which is called ocular side.

Background: Piwi-interacting RNAs (piRNAs) have been linked to epigenetic and post-transcriptional gene silencing of retrotransposons in germ line cells, particularly in spermatogenesis. Exosomes are important mediators of vesicle transport, and the piRNAs in exosomes might play an important role in cell communication and signal pathway regulation. Moreover, exosomic piRNAs are promising biomarkers for disease diagnosis and physiological status indication.

In mammals, small RNAs enclosed in exosomes have been identified as appropriate signatures for disease diagnosis. However, there is limited information on exosomes derived from seminal plasma, and few studies have reported analyzed the composition of exosomes and enclosed small RNAs in fish. The half-smooth tongue sole (Cynoglossus semilaevis) is an economically important fish for aquaculture, and it exhibits sexual dimorphism: the female gender show higher growth rates and larger body sizes than males.
