Objectives: The purpose of this study is to use the second internal transcribed spacer (ITS-2) to determine the molecular characteristics of Sarcoptes scabiei in rabbits from several areas of East Java. Methods: Collecting S. scabiei mites from rabbits with clinical signs of scabies; DNA extraction with minikit QIAamp DNA; polymerase chain reaction amplification; nucleotide sequence analysis; homology and phylogenetic tree using the Neighbor-Joining method in the program molecular evolutionary genetics analysis-7 (MEGA-7). Results: Sequence analysis of ITS-2 S. scabiei from five regions in East Java showed an identity >91.23% with isolates from China (KX695125.1). The phylogenetic analysis of ITS-2 S. scabiei from Mojokerto rabbits has a close relationship with AB82977.1; Surabaya and Nganjuk rabbits are closely related to KX695125.1; while Sidoarjo and Pasuruan rabbits are closely related to EF514469.2. and AB369384.1. Conclusions: The homology analysis of all samples showed identity of more than 91.23% with isolate China (KX695125.1). The sequences of ITS-2 gen of S. scabiei from rabbits in several areas were relatively close to S. scabiei obtain various hosts from National Centre for Biotechnology Information (NCBI) data.
