Identification of a secretory heme‐binding protein from Nocardia seriolae involved in cell apoptosis

Journal of Fish Diseases, 2022
AbstractAccording to the whole‐genome bioinformatics analysis, a heme‐binding protein from Nocardia seriolae (HBP) was found. HBP was predicted to be a bacterial secretory protein, located at mitochondrial membrane in eukaryotic cells and have a similar protein structure with the heme‐binding protein of Mycobacterium tuberculosis, Rv0203. In this study,

Isolation and genetic characterization of Nocardia seriolae from snubnose pompano Trachinotus blochii in Vietnam

Diseases of Aquatic Organisms, 2016
A total of 480 cage-cultured fish were collected from 4 coastal provinces in central Vietnam to investigate the causative agent of nocardiosis. Fish displayed unique characteristics such as paleness and lethargy and exhibited haemorrhages and ulcers on the skin.

Evaluation of immunological effects of two DNA vaccines against Nocardia seriolae in hybrid snakehead

Fish & Shellfish Immunology
Although DNA vaccines hold significant potential, their practical application in aquaculture remains limited. In both mammals and teleost fish, B cells, which recognize antigens and produce antibodies, play an important role in immunity. In this study, B-cell epitopes capable of inducing fish immunity from IS701 family transposase (IS701) and ...

The combination effect of N -acetyl- d -glucosamine on oral oxytetracycline treatment against Nocardia seriolae infection in the yellowtail Seriola quinqueradiata

Aquaculture, 2018
Abstract Nocardia seriolae infection is one of the most serious bacterial diseases in Seriola species in Japanese aquaculture. In this study, the combination effect of N -acetyl- d -glucosamine (NAG) with oral oxytetracycline (OTC) treatment was evaluated with the experimental infection of artificially bred juvenile yellowtail Seriola ...

Pathological variations and immune response in Channa argus infected with pathogenic Nocardia seriolae strain

Fish & Shellfish Immunology
Nocardia seriolae pathogen causes chronic granulomatous disease, reportedly affecting over 40 species of marine and freshwater cultured fish. Hence, research is required to address and eliminate this significant threat to the aquaculture industry. In this respect, a reliable and reproducible infection model needs to be established to better understand ...

LECT2 mediates antibacterial immune response induced by Nocardia seriolae infection in the northern snakehead

Fish & Shellfish Immunology
Leukocyte-derived chemotaxin-2 (LECT2) is a multifunctional immunoregulator that plays several pivotal roles in the host's defense against pathogens. This study aimed to elucidate the specific functions and mechanisms of LECT2 (CaLECT2) in the northern snakehead (Channa argus) during infections with pathogens such as Nocardia seriolae (N. seriolae). We

Pathogenicity, ultrastructure and genomics analysis of Nocardia seriolae isolated from largemouth bass (Micropterus salmoides)

Microbial Pathogenesis
Fish granulomatous diseases induced by Nocardia seriolae have caused significant economic losses in global aquaculture. Understanding the structural and genetic basis of N. seriolae' s survival and immune evasion strategies is crucial. However, while some aspects of its pathogenicity have been explored, a comprehensive characterization of its ...

A methionine sulfoxide reductase A homolog gene(msrA1)deficiency significantly attenuates the virulence of Nocardia seriolae

Fish & Shellfish Immunology
Nocardia seriolae, a facultative intracellular pathogenic actinobacteria, is the primary aetiological agent of nocardiosis in both freshwater and marine fish. Methionine sulfoxide reductases (Msrs) has been shown to play important role in defensing against oxidative stress in many pathogenic bacteria.
