title: Effects of the probiotic Arthrobacter sp. CW9 on the survival and immune status of white shrimp (Penaeus vannamei).
abstract: The probiotic Arthrobacter sp. CW9 isolated from guts of white shrimp (Penaeus vannamei) was used to improve the survival rate, growth rate and immune status of white shrimp (P. vannamei). Arthrobacter sp. CW9 was added to the saline rearing water at 0, 10(5), 10(6) and 10(7) CFU ml(-1) once every 5 days during the 24-day breeding experiment. The probiotic group had significantly higher survival rates, mean shrimp weights, phenoloxidase activity, phagocytic activity and clearance efficiency compared with the control group (P < 0.05). Therefore, Arthrobacter sp. CW9 has both probiotic and immunostimulatory properties.
  
  
  CONCLUSIONS
  This study demonstrates that Arthrobacter sp. CW9 has both probiotic and immunostimulatory properties. Such new strain therefore represents an alternative to the use of white shrimp (Penaeus vannamei) culture. New bacterial having both probiotic and immunostimulatory properties are the major novelty of this study. The results are of industrial relevance.
