Nocardia seriolae sp. nov. Causing Nocardiosis of Cultured Fish

International Journal of Systematic Bacteriology, 1988
Five strains of bacteria causing nocardiosis in cultured fishes (yellowtails [Seriola quinqueradiata] and Japanese flounder [Paralichthys olivaceus]) were studied to establish their taxonomic status. Well-developed fragmenting vegetative mycelium was observed. The chemotype was type IVA containing meso-diaminopimelic acid, arabinose, and galactose. The

Nocardia seriolae infection in cultured jade perch, Scortum barcoo

Aquaculture International, 2017
Nocardiosis is a chronic infectious disease that afflicts multiple fish species and poses a growing threat to the aquaculture. In this study, Nocardia sp. infection was identified in jade perch, Scortum barcoo, from a pond culture in Guangzhou, China.

Induction of attenuated Nocardia seriolae and their use as live vaccine trials against fish nocardiosis

Fish & Shellfish Immunology, 2022
Nocardia seriolae, a Gram-positive facultative intercellular pathogen, has been identified as the causative agent of fish nocardiosis, causing substantial mortality and morbidity of a wide range of fish species. Looking into that fact, the effective vaccine against this pathogen is urgently needed to control the significant losses in aquaculture ...

Characterization and function study of a glutamyl endopeptidase homolog from Nocardia seriolae

Journal of Fish Diseases, 2020
AbstractGlutamic endopeptidases (Glu), belonging to the class of serine proteases, are a subfamily of chymotrypsin‐like proteolytic enzymes, which are regarded as important virulence factors in bacteria. However, the roles of glutamic endopeptidases of Nocardia seriolae in pathogenic process still remain uncertain.

Nocardia seriolae infection in the cultured eel Anguilla japonica in Korea

Journal of Fish Diseases, 2018
AbstractMass mortality occurred at an Anguilla japonica eel farm equipped with a recirculating aquaculture system in Gimcheon, Korea, from late spring to early summer 2015. The cumulative 3‐month mortality was 16% (approximately 24,300–150,000 fish). The majority of affected fish displayed ulcerative lesions that progressed to petechial haemorrhages ...

Nocardia seriolae cell wall lipids: An effective protective mechanism in resistance and virulence

Journal of Fish Diseases, 2023
AbstractPiscine nocardiosis, caused by Nocardia seriolae, is a refractory granulomatous disease in South‐East Asian aquaculture. This study investigates the virulence of nocardial lipids essential for pathogenesis among Actinomycetes. Petroleum ether (PE) was used to selectively delipidate two groups of N.

Genetic and phenotypic comparison of Nocardia seriolae isolated from fish in Japan

Journal of Fish Diseases, 2008
AbstractThe phenotypic and genetic characterizations of 58 isolates of the fish pathogen Nocardia seriolae, from amberjack, Seriolae dumerili, yellowtail, Seriola quinqueradiata, Japanese flounder, Paralichthys olivaceus, and chub mackerel, Scomber japonicus, in Japan from 1970–2005, were examined to investigate the epidemiological relationship between

Molecular characterization and biological function of CXCR1 in Nocardia seriolae-infected largemouth bass (Micropterus salmoides)

Tissue and Cell, 2021
Interleukin-8 (IL-8, CXCL8), a pro-inflammatory chemokine secreted by a variety of cell types, plays a critical role in the development of various immune diseases. Interactions between IL-8 and its receptor CXC receptor 1/2 (CXCR1/2) are known to promote chemotaxis and phagocytosis in many immune responses.

The absorption-enhancing effect of citric acid on oral oxytetracycline treatment against Nocardia seriolae infection in yellowtail, Seriola quinqueradiata

Aquaculture, 2019
Abstract Nocardia seriolae infection is one of the most serious bacterial diseases in Seriola species in Japanese aquaculture. In this study, the absorption-enhancing effect of citric acid on oral oxytetracycline (OTC) treatment against nocardiosis was evaluated with experimentally infected juvenile yellowtail, Seriola quinqueradiata, followed by ...
