The objective of this research was to evaluate the nonspecific immune response and resistance of Litopenaeus vannamei fed with nucleotide, β–glucan, and protagen diets. Shrimp juveniles with an average weight of 5.39±0.56 g were reared in glass aquaria at a density of 15 shrimps/aquarium. Shrimps were fed three times a day for four weeks at a feeding rate of 3%/bw/day. Treatment diets consisted of A: basal diet (without immunostimulant), B: β–glucan, C: protagen, and D: nucleotide, each with three replicates.

Abstract Active promoters are urgently needed for shrimp cells which are hard to be immortalized. Translationally controlled tumor protein (TCTP) is a widely and abundantly expressed, growth-related protein. In this study we successfully isolated the promoter (Ptctp) and ORF (= open reading frame) of the TCTP gene from Litopenaeus vannamei and analysed the promoter activity of Ptctp and the growth-promoting effects of over-expressed TCTP protein in the primary Oka organ (lymphoid tissue) cells.

The pathogenic bacterial infection is one of the problems in the cultivation of vannamei shrimp (Litopenaeus vannamei), causing a high mortality rate of cultured shrimp.

One way to control and prevent shrimp disease is to increase the shrimp immune system by using immunostimulants from seaweed. This study aims to analyze the immunostimulant activity

Higher temperature (25 and 37°C) and acidic pH increased the bactericidal effects of chitosan.
