This thesis is focused on polymorphism of MDR1 gene and related drug resistance. Resistance is caused by deletion of four nucleotids, that resulting in a frame shift and synthesis of nonfunctional transport of P-glycoprotein. The text describes a polymorphism of MDR1 (ABCB1) gene, which results in reduced resistance to drugs belonging to the group of macrocyclic lactones. It also describes inheritance of this phenomenon and it deals with the detection of mutation using PCR (polymerase chain reaction) and by fragmentation analyses. A review of literature study is a form of research solely from scientific publications. 128 dogs were included into the own analysis. The results confirmed that Collies had the highest presence of deletions (29,73 %) with a high number of carriers in the study population of dogs (54,05 %). The percentage of affected individuals in the breed of Australian Shepherd and Sheltie was significantly lower (7,32 % and 6 %), but the percentage of carriers were also high in both Australian Shepherds (34,14 %) and the breed Sheltie (48 %).
