“…It is known that the infected control group showed a tendency to increase LOOH levels since infected controls at 4 DPI had a reduced level of this biomarker. In experiments conducted with Carassius auratus gibelio (gibel carp) (Yang et al 2015a) and Ictalurus punctatus (channel catfish) (Yang et al 2015b), the challenge with A. hydrophila did not provide statistical variation in plasmatic MDA levels 7 DPI, corroborating the present study, despite different determinations for the assessment of oxidative damage and distinct fish species.…”

“…Total antioxidant capacity (TAC) remained unchanged at 4 and 7 DPI by A. hydrophila, both in muscle and liver tissue. The same was verified by Yang et al (2015a) and Liu et al (2013) in plasma and liver tissue, respectively, of gibel carp 7 DPI by this pathogen. Zhao et al (2019) found that hepatic TAC remained unchanged at 28 DPI by A. hydrophila and reduced after 56 days in grass carp.…”

The growing increase in the fish farming sector has favored the establishment of bacterial outbreaks caused by Aeromonas hydrophila in several species. The hexane extract of Hesperozygis ringens (HEHR) (Lamiaceae) leaves increased the survival rate of silver catfish (Rhamdia quelen) experimentally infected by A. hydrophila. However, it is noteworthy that no reports have been found on the possible mechanisms of action of this extract in infected fish. This study aimed to evaluate the effect of the HEHR, administered through single immersion bath, on lipid peroxidation and antioxidant defenses in muscle and liver tissue of silver catfish challenged with A. hydrophila. The results showed that the oxidative status of silver catfish was altered, although oxidative stress was not triggered during the experiment. HEHR at 30 mg/L (HEHR30) was not characterized as a pro-oxidant agent in the presence of infection, unlike florfenicol and HEHR at 15 mg/L treatments in some cases. In short, HEHR30 provided an important increase in hepatic catalase activity, characterizing one of the possible mechanisms involved in the greater survival of fish experimentally infected by A. hydrophila.Additionally, HEHR30 did not induce lipid peroxidation, nor reduced antioxidant defenses of silver catfish infected or not by A. hydrophila.

“…In the present study, A. hydrophila infection significantly induced the mRNA abundance of immune-related genes (INF-γ2, IL-4, IL-6, TNF-α, IL-12p40 and M-CSF2) in the spleen and kidney tissues of grass carp among the SI-supplemented groups and the control group, except splenic IL-4 expression. Similarly, in some else's fish species, such as zebrafish (Roca et al, 2008) and channel catfish (Yang et al, 2015), the transcription levels of immune-related genes were significantly upregulated with A. hydrophila injection. A previous research has revealed that the activation of immune-related genes following A. hydrophila injection probably due to the presence of a cytotoxic enterotoxin, aerolysin, in the pathogen (Silvia, Daniel, & Marisol, 2014).…”

In recent decades, due to the continuous increasing demand for aquatic products, the global fishery industry has been expanding rapidly, and aquaculture output has been increasing at an unprecedented speed (Cole et al., 2009). High-density aquaculture is the current mainstream aquaculture modes worldwide. While the environmental stress induced by high rearing density results in poor resistance to disease and vulnerability to infection by pathogenic microorganisms in fish (Costas, Aragão, Mancera, Dinis, & Conceicão, 2008). For a long time, many antibiotics and chemotherapeutic agents have been used to improve non-specific immunity and to treat some bacterial infections in aquatic animals, but these agents also lead to undesirable effects, such as antibiotic resistance, pharmaceutical bioaccumulation and environmental pollution (Bilen, Bulut, & Bilen, 2011;Harikrishnan, Balasundaram, & Heo, 2011). In recent years, many harmless therapeutic techniques and

“…According to inferred migratory routes, croaker aggregate in overwintering grounds from October to April each year (Liu and de Mitcheson, 2008;Xu and Chen, 2011;Chen and Xu, 2012). Because the low temperature may suppress croaker immune functions by influencing multiple physiological processes and thereby make the croaker susceptible to the surrounding environment (Yang et al, 2015;Liu et al, 2019), the habitat conditions of their overwintering grounds are vital for recovering their stock and supporting this marine resource.…”

Structure and Functional Diversity of Surface Bacterioplankton Communities in an Overwintering Habitat for Large Yellow Croaker, Pseudosciaena crocea, of the Southern East China Sea

et al. 2020

Given the biogeochemical functions of marine microbes, the structure and functional diversity of bacterioplankton communities could be regarded as bioindicators that reflect environmental quality. The habitat of the large yellow croaker (Pseudosciaena crocea) is suffering from widespread degradation, but the study of the croaker habitat is still insufficient. Here, we used 16S rRNA gene sequencing and functional prediction to investigate the surface bacterioplankton communities in an overwintering ground of P. crocea during the overwintering period (November 2018 to April 2019). Our results showed that the taxa and functions of the environmental bacterioplankton community exhibited obvious seasonality. Specifically, the bacterioplankton communities in autumn were characterized by animal parasites or symbionts, such as Acinetobacter baumannii and Moraxella, while organic substance-degrading bacteria, such as Rhodococcus, Stenotrophomonas, and Alcanivorax, dominated in spring. Moreover, phylogeneticbased mean nearest taxon distance (MNTD) analyses indicated that dispersal limitation was the most important process governing the spatiotemporal assembly of the bacterioplankton communities. The distance decay of similarity also suggested the impact of dispersal limitation on the generation of biogeographical patterns. Furthermore, variation partitioning analysis (VPA) and a partial Mantel test revealed that environmental filters, such as nutrients, temperature, and salinity, had relatively weak deterministic effects on the bacterioplankton community assembly. Overall, these findings provide a basis for understanding the theory of surface microbial community assembly in the overwintering habitat of the large yellow croaker.
