Abstract

We isolated a novel bacteriophage from Lake Baikal that infects Pseudomonas fluorescens. Transmission electron microscopy revealed that phage PfAn1 has a head with a diameter of 50 nm and a short tail. Its genome is 39,156 bp in length with a GC content of 57%. It is predicted to contain 53 open reading frames (ORFs). The results of evolutionary analysis suggest that phage PfAn1 should be considered a new member of the class Caudoviricetes.

贝加尔湖感染荧光假单胞菌的新型噬菌体PfAn1的基因组特征

我们从贝加尔湖分离出一种感染荧光假单胞菌的新型噬菌体。透射电镜显示，噬菌体PfAn1具有直径为50 nm的头部和短尾。基因组长39156 bp， GC含量为57%。预计它包含53个开放阅读帧（orf）。进化分析结果表明，噬菌体PfAn1应被认为是尾柱菌纲的新成员。

期刊介绍： Archives of Virology publishes original contributions from all branches of research on viruses, virus-like agents, and virus infections of humans, animals, plants, insects, and bacteria. Coverage spans a broad spectrum of topics, from descriptions of newly discovered viruses, to studies of virus structure, composition, and genetics, to studies of virus interactions with host cells, organisms and populations. Studies employ molecular biologic, molecular genetics, and current immunologic and epidemiologic approaches. Contents include studies on the molecular pathogenesis, pathophysiology, and genetics of virus infections in individual hosts, and studies on the molecular epidemiology of virus infections in populations. Also included are studies involving applied research such as diagnostic technology development, monoclonal antibody panel development, vaccine development, and antiviral drug development.Archives of Virology wishes to publish obituaries of recently deceased well-known virologists and leading figures in virology.
