Morganella psychrotolerans is a histamine-producing bacterium that causes histamine poisoning. In this study, we isolated and characterized a novel phage, MopsHU1, that infects M. psychrotolerans. MopsHU1 is a podovirus with a limited host spectrum. Genomic analysis showed that MopsHU1 belongs to the family Autographiviridae, subfamily Studiervirinae, and genus Kayfunavirus. Comparative analysis revealed that the MopsHU1 genome is similar to those of Citrobacter phage SH3 and Cronobacter phage Dev2. Moreover, the Escherichia coli phage K1F genome is also similar, except for its tailspike gene sequence. These results expand our understanding of the Kayfunavirus phages that infect Morganella spp. Note: The nucleotide sequence data reported here are available in the DDBJ/EMBL/GenBank database under the accession number LC799501.
摩氏摩根菌是一种产组胺的细菌，可导致组胺中毒。在本研究中，我们分离并鉴定了一种新型噬菌体 MopsHU1，该噬菌体可感染摩氏摩根菌。MopsHU1 是一种具有有限宿主范围的 Podovirus。基因组分析表明，MopsHU1 属于 Autographiviridae 科，Studiervirinae 亚科，Kayfunavirus 属。比较分析表明，MopsHU1 基因组与柠檬酸杆菌噬菌体 SH3 和 Cronobacter 噬菌体 Dev2 相似。此外，大肠杆菌噬菌体 K1F 的基因组也相似，除了其尾刺蛋白基因序列。这些结果扩展了我们对感染摩根菌属的 Kayfunavirus 噬菌体的认识。注：本文报道的核苷酸序列数据已在 DDBJ/EMBL/GenBank 数据库中作为 LC799501 号登录号可用。
