Differential immune responses of the green neon shrimp (Neocaridina denticulate) to dipropyl phthalate
چکیده انگلیسی

This study set out to understand the sublethal effect of xenobiotic phthalate esters (PAEs) on the relationship between the susceptibility of shrimp to bacterial infection and the immune response of the shrimp. Neocaridina denticulate were exposed to different concentrations of the PAE dipropyl phthalate (DPrP), and mortality and six immune parameters were measured on days 1, 3, 5, and 10 after exposure. On days 1 and 3 after exposure, shrimp exposed to 0, 1, 5, 10, and 50 mg/L of DPrP and challenged with Aeromonas veronii experienced 14% and 16%, 16% and 16%, 18% and 18%, 34% and 24%, and 38% and 26% mortality, respectively. On day 1, five immune parameters (acid phosphatase, AcP; β-glucuronidase, β-Glu; phenoloxidase, PO; superoxide dismutase, SOD; and haemocyanin mRNA) were significantly altered in the all of the groups treated with DPrP compared to the untreated shrimp and were elevated in the 10 mg/L- and 50 mg/L-treated groups. Beta–Glu activity and haemocyanin mRNA levels were significantly increased in a dose-dependent manner. These results suggest that the increased susceptibility of N. denticulate exposed to DPrP is short-term and may be related to the increased expression of DPrP-induced immune mediators.


► The susceptibility of N. denticulate exposed to DPrP to infection was increased.
► The immune functions of N. denticulate were affected by DPrP.
► The expression of immune-related gene was varied depending on the DPrP concentration.
► The most response to DPrP occurred less than 10 days after exposure.
