Nepenthes is a protected and unique carnivorous plant because it has a fluid-filled pouch at the end of the leaf that serves as an insect trap. The existence of  Nepenthes gracillis  in ecosystems is endangered, one of the reasons is caused by the attack of pathogenic bacteria, so it is necessary to identify pathogenic bacteria that attack  N. gracillis  as an effort to handle. The purpose of this study was to identify pathogenic bacteria in  N. gracillis  using 16S rRNA gene sequencing results. This study aims to identify the 16S rRNA sequence and phylogenetic of bacteria attached in  N. Gracillis  leaves, and the identification was confirmed using molecular data. The construction of phylogenetic topology was made based on ML and NJ method using Kimura-2 parameter model. Subsequently, molecular characterization and identification was conducted based on 720 bp of 16S rRNA gene similarity, sequence variation, genetic distance, and phylogenetic topology. According to the results, the bacteria species attached in  N. Gracillis  identified as  Lelliottia nimipressuralis , and closely related with  Erwinia aphidicola . Genetic distance between sample and related species was 0,0173, with 98,26% similarities, then strongly 100 bootstrap analyses. Thus, this study provides more information for  Lelliottia nimipressuralis  phylogenetic studies using different marker.
