The study aimed at assessing the parameters of the innate cellular response in streptococcosis and mixed respiratory infections in swine. Flow cytometry was used to determine the phagocytic and oxidative burst activity of neutrophils and monocytes. In Streptococcus suis infection, monocytosis was accompanied by a lower percentage of all phagocyting cells in comparison to the control group, and a lower respiratory burst activity of monocytes was observed. In Streptococcus suis, Mycoplasma hyopneumoniae, and porcine reproductive and respiratory syndrome virus infection, the percentage of phagocyting neutrophils and the percentage of neutrophils that succumbed to an oxidative burst were lower than in the control group, but the mean fluorescent intensity was higher in both tests. The oxygen burst activity of monocy tes was also higher.
