摘　　要：应用石蜡切片法调查了不同龄期养殖斑节对虾 (Penaeusmonodon)的斑节对虾杆状病毒 (Penaeusmonodonbaculovirus ,MBV)感染率和感染度 .结果表明 :各龄期养殖斑节对虾的MBV感染率达 10 0 %或接近 10 0 % .MBV感染度以养殖早期较高 (最高可达 142 317‰ ) ,养殖中期下降 (最低为 11 334‰ ) ,养殖后期又呈上升趋势 .这与对虾的免疫状况及环境的改变有关 .The infection rate and the infection severity grade of MBV in different cultured stage of Penaeus monodon were investigated by light microscopy. Results indicated that the infection rates of MBV were 100% or near 100% in different cultured stages. The infection severity grade was the highest in early cultured stage and dropped subsequently in middle cultured stage and rose in late cultured stage because of the change of water condition.
