文蛤為臺灣重要的經濟性雙殼綱軟體動物。文蛤的生長和存活容易受到水溫、鹽度和病原體等各種環境因素的影響。本研究旨在利用奈米孔定序 (nanopore sequencing) 分析臺灣淡水河文蛤群體腸道菌的組成，解剖10個淡水河產文蛤樣本 (Meretrix taiwanica) 並採取腸道後，萃取細菌核酸並進行聚合酶連鎖反應、定序及菌相分析。由定序結果發現，文蛤腸道菌中的主要分類群包含具耐熱特性的地芽胞桿菌屬 (Geobacillus)、芽孢桿菌屬 (Bacillus)、尿素芽孢桿菌屬 (Ureibacillus) 及具固氮能力之硝化弓形菌 (Arcobacter nitrofigilis)。除此之外，也在文蛤腸道中發現另一種也在貽貝體內發現過的弓形菌屬種類 (Arcobacter mytili)。這些共生菌可能可以幫助文蛤個體適應野外劇烈變化的氣候環境並確保其生存能力。
摘要abstract(英) The Asian hard clam (Meretrix taiwanica) is a commercially important bivalve species in Taiwan. The clam’s growth and survival are influenced by environmental factors such as water temperature, salinity, and pathogens. This study focuses on analyzing the composition of gut symbiotic bacteria in the hard clam population from the Tamsui River, Taiwan, using nanopore sequencing. The sequencing results indicate that thermophilic bacteria (specifically, the genera Geobacillus, Bacillus, and Ureibacillus) and nitrogen-fixing bacteria (Arcobacter nitrofigilis) predominate in the gut microbiota of hard clams. Furthermore, an Arcobacter species detected in hard clams was also found in mussels. These symbiotic bacteria may assist hard clams in adapting to their environment and ensuring their survival.
