In this work the genotoxic effect of the antibiotic preparation Tiamulin S was investigated. The experiments were done in vivo using cytogenetic analysis on BALB/c mouse bone marrow cells. The occurrence of chromosomal alterations was monitored in bone marrow and germ cells. The clastogenic effect of Tiamulin S was monitored at three doses (0.01 ml/kg, 0.2 ml/kg and 0.4 ml/kg) through eight experimental cycles. The results obtained showed that Tiamulin S induces kariotype changes including both numerical (aneuploidies and polyploidies) and structural chromosomal aberrations (lesions, breaks and Robertsonian translocations). Thus, Tiamulin S exerts genotoxic potential. In addition, a clear dose-response effect was observed in this investigation.
