The immune response of white shrimp Litopenaeus vannamei following Vibrio alginolyticus injection
چکیده انگلیسی

White shrimp Litopenaeus vannamei injected with saline, and injected with tryptic soy broth (TSB)-grown Vibrio alginolyticus at 1.0 × 105 and 1.8 × 105 colony-forming units (cfu) shrimp−1 were examined for hyaline cell (HC) counts, granular cell (GC) counts, total haemocyte counts (THCs), phenoloxidase (PO) activity, respiratory burst (RB) and superoxide dismutase (SOD) activity after 1–168 h. Shrimp that received no injection served as the control. The shrimps which received V. alginolyticus at both doses showed significant decreases in these parameters after 6–96 h. The values for HC and SOD activity decreased earlier and then RB. The time to cause maximum depletion of haemocytes (haemocytopenia), PO activity, RB, and SOD activity were 12, 72, 48, and 24 h post-injection, respectively. The HC, GC, and RB returned to the original values earlier at 72 h, followed by SOD activity at 96 h, and then PO activity at 168 h post-infection. It was concluded that an injection of V. alginolyticus rapidly reduced the shrimp's immunity by decreasing HC, GC, SOD activity, RB, and PO activity within 3–24 h, followed by a slow recovery during 72–168 h post-injection. Furthermore, white shrimp L. vannamei which received V. alginolyticus showed a 6–9 h later response in PO activity, and a 72–96 h later recovery of PO activity, compared to the responses in RB and SOD activity indicating their roles in shrimp defence and immunity.
