Comparative pathological description of nocardiosis in largemouth bass (Micropterus salmoides) and other Perciformes

Largemouth bass (Micropterus salmoides) exhibited better growth potential after adaptation to dietary cottonseed protein concentrate inclusion but experienced higher inflammatory risk during bacterial infection

“…Largemouth bass is rather sensitive to N. seriolae infection, which caused serious hepatic damage and even mortality ( 14 ). In order to further illustrate the immune responses of bass liver during pathogenic infection, all bass was injected with N.a seriolae .…”

“…As mentioned above, N. seriolae infection seriously affected the health of largemouth bass and resulted in the damage of internal organs including liver and eventual high mortality ( 14 ). N. seriolae infection has been reported to induce high inflammatory responses in bass liver ( 21 ) while little information is known about the metabolic control of such inflammatory responses in liver.…”

“…Liver structure was reported to be significantly affected by dietary glucose level ( 13 ). Additionally, N. seriolae infection, which is rather common in largemouth bass aquaculture, also caused serious hepatic damage ( 14 ). In fact, liver receives dual blood supply from the portal vein and hepatic artery, and both acts as the metabolic center and performs immune-regulatory roles ( 15 ).…”

Screening and evaluating honokiol from Magnolia officinalis against Nocardia seriolae infection in largemouth bass (Micropterus Salmoides)

“…The causative agent of nocardiosis is the gram‐positive, aerobic, filamentous bacterium Nocardia spp., of which Nocardia seriolae is the most frequent species (Hoang et al, 2020; Lei et al, 2020). Since the first case of N. seriolae infection reported in seabass in 2000, more than 20 freshwater and marine fish species have been found to be susceptible to this pathogen (Chen et al, 2000; Huang et al, 2021). At present, N. seriolae has become a primary pathogenic bacterium in aquaculture, posing an increasing threat to aquaculture industry, especially in Asia (Huang et al, 2021; Lei et al, 2020; Wang et al, 2009).…”

Rapid visual detection of Micropterus salmoides rhabdovirus using recombinase polymerase amplification combined with lateral flow dipsticks

Largemouth bass (Micropterus salmoides), a member of the family Centrarchidae, is a freshwater fish species originating from North America, introduced into Guangdong Province, China, in 1983(Guo et al, 2020. Nowadays, owing to its breeding advantages such as high adaptability, rapid growth and delicious flesh, largemouth bass becomes one of the most popular and important aquaculture species with extensive cultivation and breeding (Huang et al, 2021), and its annual production has already reached 477,808 tons (Ministry of Agriculture & Rural Affairs Fisheries Administration Bureau, 2020). Unfortunately, a new viral disease impacted the largemouth bass aquaculture industry in Guangdong Province, China, in 2011, resulting in 200,000 fish deaths and substantial economic losses (Ma et al, 2013).
