Hydatigera taeniaeformis (formerly known as Taenia taeniaeformis) is a parasitic tapeworm that has a worldwide distribution. H. taeniaeformis is naturally transmitted between mice and cats and threatens to human health, especially those who are in close contact with pets. MicroRNAs (miRNAs) are a class of small regulatory non-coding RNAs involved in the regulation of parasite growth and development, parasite infection and immunology, and host-pathogen interactions. The miRNA profile of H. taeniaeformis remains to be elucidated. Herein, 47 conserved miRNAs (grouped into 34 miRNA families) and 4 novel miRNAs were identified in H. taeniaeformis metacestodes using deep sequencing approach. Among them, hta-miR-71, -let-7, and-miR-87 was absolutely predominant in H. taeniaeformis metacestodes. Moreover, comparative analysis revealed the presence of miR-71/2 and miR-4989/277 clusters in H. taeniaeformis. Nucleotide bias analysis of identified miRNAs showed that the adenine (A) was the dominant nucleotide at the beginning of the miRNAs, particularly at the positions of third and 7th nucleotides. The study provides rich data for further understandings of H. taeniaeformis biology.
