停乳链球菌对日本沼虾总超氧化物歧化酶活性的影响
Effect ofStreptococcus dysgalactiae equisimilis on Total SOD Activity in Macrobrachium nipponense
摘要
Abstract
Total superoxide dismutase(T-SOD)activities were investigated in hepatopancreas, muscle and gill ofMacrobrachium nipponense at 3 h, 6 h, 9 h, 12 h, 24 h, 5 d and 10 d after being challenged byStreptococcus dysgalactiae equisimilis at levels of0.6×106, 2×106, 4×106 or 6×106 CFU/mL in this study. Results showed that activity of T-SOD in hepatopancreas of the prawn reached the maximum at 5 d after infection. The values in muscle and gill reached to a maximum at 6 h. The activities of T-SOD in the hepatopancreas and gill of prawns infected with 6×106 CFU/mL bacteria, in the muscle of prawns infected with 4 × 106 or 6 × 106 CFU/mL bacteria at 10 d decreased to about half of that in the control group. And the maximum in muscles was higher than those in hepatopancreas and gills. The results showed thatStreptococcus dysgalactiae equisimilis could affect the activity of SOD inM. nipponense,and the response of the prawn to the bacteria was different in hepatopancreas, muscle and gill.关键词
