Characterization of Haemaphysalis longicornis microbiome collected from different regions of Korean peninsula

초록

Ticks are vectors that cause disease by transmitting bacteria, viruses, and protozoa to humans or animals. The Asian longhorned tick Haemaphysalis longicornis, a vector of medical and veterinary importance, is widely distributed in the Korean peninsula and can transmit various pathogens including Rickettsia spp., Borrelia spp., Francisella spp., Coxiella spp., and severe fever with thrombocytopenia syndrome virus (SFTS virus). Despite the abundance and importance, studies on the microbiome of H. longicornis in Korea are limiting. Here we first report the microbiome diversity of H. longicornis in terms of region, stage, and sex. H. longicornis used in this study were collected from 16 different regions. The V3-V4 region was amplified and sequenced by MiSeq platform. The microbial diversity analysis was performed using Qiime2. A total of 1,754,418 non-chimeric reads were obtained from a total of 46 samples, and an average of 126 operational taxonomic units (OTUs) and a total of 1,398 OTUs were identified. Our results were used for H. longicornis microbial community database construction for each region that enables to identify singularities in each region.
