Bacterial Survey in the Guts of Domestic Silkworms, Bombyx Mori L.

The domestic silkworm is central to the silk industry. Current sericulture efforts have also shifted toward the improvement of silkworm strains in terms of silk yield, silk quality and disease resistance to support the growing demand for silk worldwide. This study offers a potential starting point for Philippine silkworm strain improvement through the use of 16S rRNA gene amplicon sequencing to study the gut microbiome of Philippine silkworm strains that were selected based on developmental and economically important traits they exhibit. The findings give insight into the bacterial genera abundant in the gut of Philippine silkworms and lay the foundation necessary for the characterization and eventual improvement of Philippine silkworm strains, as well as other related studies in the future.

家蚕是蚕丝产业的核心支柱。当前养蚕产业的研发重心已转向提升家蚕品系的蚕丝产量、品质与抗病能力，以适配全球日益增长的蚕丝需求。本研究借助16S rRNA基因扩增子测序（16S rRNA gene amplicon sequencing）技术，对基于发育与经济重要性状筛选得到的菲律宾家蚕品系的肠道微生物组开展分析，为菲律宾家蚕品系的改良提供了潜在的切入点。研究结果揭示了菲律宾家蚕肠道内的优势细菌属类群，为菲律宾家蚕品系的性状解析与后续改良奠定了必要基础，同时也为未来相关研究提供了重要支撑。
