Labeo rohitaandArgulus siamensisinfection: Host size, local inflammatory reaction and immunity modulate ectoparasite load on fish

Aquaculture Research (2017)

Parasite species often show a heterogeneous, highly dispersed pattern of infestation within hosts. Varieties of factors including morphological, physiological, immunological and nutritional characteristics affect the infestation level of a specific parasite in homogenous pray. Limited attempts, however, have been made to explore such underlying drivers of infestation pattern. Here, three stages of Labeo rohita (fingerling, juvenile and pre-adult) were challenged with ectoparasite, Argulus siamensis in same aquaria. The parasite load on individuals was determined at 5-day interval for 1 month. The load was found to be highest in pre-adult stage followed by juveniles and fingerlings. On day 20 post infection, the load of parasite on pre-adult fish was high along with detectable skin damages. Skin tissues were collected for immune gene expression analysis and histopathology. Histological studies showed increased melanization in the dermis and mild inflammatory cellular reactions in pre-adult fish whereas, massive subcutaneous myositis with engorged blood vessels were observed in fingerlings. The expression levels of various inflammation and innate immune-related genes viz., interleukin (IL)-8, IL-10, IL-11, IL-15, natural killer enhancing factor, toll-like receptor 4, apolipoprotein A–I and immunoglobulin Z were significantly high in skin samples of infected fingerlings as compared to other two growth stages or controls of each stage. On the other hand, the expression of immunoglobulin M was down-regulated in all infected samples as compared to their respective controls. The results thus depict that local immuno-inflammatory response plays a significant role in determining susceptibility of host in intra-specific group, and has important implications for ecology and aquaculture.

Antioxidant Defence in Labeo rohita to Biotic and Abiotic Stress: Insight from mRNA Expression, Molecular Characterization and Recombinant Protein-Based ELISA of Catalase, Glutathione Peroxidase, CuZn Superoxide Dismutase, and Glutathione S-Transferase

Antioxidants (2023)

Sonali Parida Pramoda Kumar Sahoo

Fish possess numerous enzymatic antioxidant systems as part of their innate immunity. These systems have been poorly studied in Labeo rohita (rohu). The present study characterized and investigated the role of antioxidant genes in the defence mechanisms against two types of stressors, including infection and ammonia stress. Four key genes associated with antioxidant activity–catalase, glutathione peroxidase, glutathione S-transferase, and CuZn superoxide dismutase were successfully cloned and sequenced. These genes were found to be expressed in different tissues and developmental stages of rohu. The expression levels of these antioxidant genes in the liver and anterior kidney tissues of rohu juveniles were modulated in response to bacterial infection (Aeromonas hydrophila), parasite infection (Argulus siamensis), poly I:C stimulation and ammonia stress. Additionally, the recombinant proteins derived from these genes exhibited significant antioxidant and antibacterial activities. These proteins also demonstrated a protective effect against A. hydrophila infection in rohu and had an immunomodulatory role. Furthermore, indirect ELISA assay systems were developed to measure these protein levels in healthy as well as A. hydrophila and ammonia-induced rohu serum. Overall, this study characterized and emphasised the importance of the antioxidant mechanism in rohu’s defence against oxidative damage and microbial diseases.
