ABSTRACT

The effect of treatment with enrofloxacin was studied on the postvaccinal immune response in pigs. Forty pigs were used (control not vaccinated (C), control vaccinated (CV), vaccinated, received enrofloxacin (ENRO)). From day -1 to day 3 pigs from ENRO group received enrofloxacin at the recommended dose. Pigs from ENRO and CV groups were vaccinated twice against Aujeszky's disease virus (ADV). There was a significant delay in the production of humoral response of enrofloxacin dosed pigs when compared with CV group. Moreover, in ENRO group the significant decrease in IFN-γ production and significantly lower values of stimulation index after ADV restimulation was noted, as compared with CV group. The secretion of IL-6, IL-10 and TNF-α by PBMC after recall stimulation was also affected in ENRO group. The results indicate that enrofloxacin, in addition to its antimicrobial properties, possess significant immunomodulatory effects and may alter the immune response to vaccines.
