The mean stimulation index values observed in pigs after vaccination against pseudorabies and swine influenza and in control, not vaccinated animals. The bold lines indicate border-line between nonspecific and antigen-specific proliferation. PR-V- pigs vaccinated against pseudorabies, no treatment with antibiotic. PR-CEF - pigs received ceftiofur hydrochloride during vaccination against pseudorabies. SI-V- pigs vaccinated against swine influenza, no treatment with antibiotic. SI-CEF - pigs received ceftiofur hydrochloride during vaccination against swine influenza. C - control pigs (unvaccinated, no antibiotic treatment). * - statistically significant differences between vaccinated groups
