Virus neutralization titers and ELISA antibodies for inactivated vaccines.

A) Virus neutralization (VN) titers generated from TAT, TTT, PAA and PTA inactivated vaccines against the TAT challenge strain at 10 wpv shows significantly higher VN titer for TAT over PAA and PTA groups (pB) Antibody response by ELISA at 10 wpv against TAT antigen coat for the TAT, TTT, PAA and PTA vaccines. TAT is different from all other groups. N = 12; ±SEM. C) VN titers of serum from fish vaccinated with different vaccines at 10 wpv. Each group of vaccine was tested against the corresponding vaccine antigen. As can be seen the trend is similar to what is seen in B) but with lower antibody levels against corresponding antigen. N = 12; ±SEM.A) 在免疫后10周（weeks post vaccination, wpv），针对TAT攻击毒株，由TAT、TTT、PAA及PTA四种灭活疫苗免疫动物所测得的病毒中和（VN）滴度结果显示，TAT组的VN滴度显著高于PAA组与PTA组（pB）。 B) 采用酶联免疫吸附试验（Enzyme-Linked Immunosorbent Assay, ELISA）检测TAT、TTT、PAA及PTA疫苗在免疫后10周时针对TAT包被抗原的抗体应答水平，TAT组与其余各组均存在显著差异。样本量N=12，数据以平均值±标准误（Standard Error of the Mean, SEM）表示。 C) 在免疫后10周（wpv）时，接种不同疫苗的鱼类血清的病毒中和（VN）滴度结果。每组疫苗均以对应疫苗抗原进行检测。可见其趋势与B组相似，但针对对应抗原的抗体水平更低。样本量N=12，数据以平均值±标准误（SEM）表示。
