  • a Different letters indicate no parallelism of probit lines at either day 7 or day 14. The criterion of parallelism was rejected when P values were <0.05.

  • b Mortality rates were scored on days 7 and 14 postinfection. CL, confidence limits calculated by normal approximation; df, degrees of freedom; ND, not defined due to low mortality rates of AgseGV within the first week.
