Abstract

The aim of the study was to evaluate the effect of tylosin, tilmicosin and roxithromycin on viability, nitro blue tetrazolium reduction (NBT) assay, chemotaxis, apoptosis and oxidative stress in bovine leukocytes in vitro conditions. The material for the study consisted of blood collected into EDTA tubes from the external jugular vein of Holstein-Friesian cattle aged 1 week to 2.5 years, during routine veterinary examinations. In leukocytes the percent of viability, nitrate ion concentration (NO), metabolic activity (NBT, nitrotetrazolium blue reduction assay), chemotactic activity and apoptosis were determined. The results indicated a slight negative effect of these macrolides on the viability of the leukocytes, and confirmed the ability of macrolides to induce apoptosis in leukocytes in vitro. These results indicate that all of the macrolides investigated exhibit a modulatory effect on the functions of leukocytes isolated from cattle of different ages. The strongest inhibitory effect on the NBT reduction assay and chemotaxis of the leukocytes was exhibited by roxithromycin, which at the same time had the least negative effect on the leukocytes.
