Abstract: he aim of our study was to evaluate the effect of macrolide antibiotics (tilmicosin, tylosin and spiramycin) on the cellular biochemistry using different cell cultures in vitro. Cellular lines from animal tissues (VERO cells - kidney cells of Macacus Rhesus, FE cells - feline embryonal cells and BHK21 - cellular line from young hamster kidneys) were used. The effect was assessed after 24 hours of culture. We studied the concentration of calcium (Ca), magnesium (Mg), sodium (Na), potassium (K), chlorides (Cl), total proteins (TP) and cholesterol (Chol). Biochemical analysis of BHK21 cells cultivated with tilmicosin showed a significant decrease in the concentration of Ca, Cl and TP in almost all experimental groups. No significant differences were found in the FE cells. The highest concentrations of tilmicosin led to a significant increase of all analyzed elements and TP in medium in the VERO cells. The effect of tylosin on the BHK21 cell metabolism showed a significant decrease in the concentration of Na and Cl in the all experimental groups and a significant decrease in the concentration of TP in the groups to which more than 700 µg.ml-1 was added. No significant differences were found in the FE and VERO cells. Biochemical analysis of BHK21 cells with spyramicin showed a significant decrease in the concentration of Na in the all experimental groups and a significant decrease in the concentration of Cl and TP in the cell cultures with 100 µg.ml-1, 150 µg.ml-1, 200 µg.ml-1, 300 µg.ml-1 concentrations of spyramycin. The highest concentrations of spyramycin caused a significant increase of Na and a significant decrease of Chol in the FE cells. No significant differences were found in the VERO cells except increased total proteins at the highest concentration of spyramycin.
