Virulent Properties of Russian Bovine Viral Diarrhea Virus Strains in Experimentally Infected Calves

Figure 4

The data on the dynamics of leukocyte concentration in 4–6-month-old calves after aerosol challenge by bovine viral diarrhea virus cytopathic strains of subtype 1b with the dose of 6 log₁₀ TCD₅₀. The values are presented as (, mean value; , 95% confidence interval) for , the number of animals per time point (1–10 days postinfection, p.i.); , the number of animals per time point (11–25 days p.i.); values obtained for both strains 3–10 days p.i. are less than in the control according to Mann-Whitney test and Student’s -test at ; values obtained for the B1 strain 5–8 days p.i. are less than for T1 strain according to Mann-Whitney test and Student’s -test at .
