The results showed that the genome of RNRV consists of 104,286 bp containing 55.2% GC content and 104 predicted ORFs were identified in the genome. Phylogenetic analysis of the complete genome revealed that RNRV should belong to the FV3-like group in genus Ranavirus, and is more closely related to RGV and STIV. These studies confirmed that the RNRV was the causative agent of this natural epizootic event and genome analysis indicated that it belongs to the FV3-like group. In addition, viral physicochemical and biological characteristics will provide a scientific basis for prevention and control. © 2020 Blackwell Verlag GmbH.AIMS Emergence and rapid dissemination of antibiotic-resistant bacteria is becoming a severe problem to public health. The search for antimicrobial substitutes for antibiotics is necessary. Lactoferricin B like peptide (LBLP) is a 23-mer antimicrobial peptide (AMP), derived from the big centipede Scolopendra subspinipes mutilans. Although its antifungal effect and its mechanism have been reported, the antibacterial activity has not yet been elucidated. METHOD AND RESULTS In this study, we investigated antibacterial activity of LBLP and its mode of action. LBLP showed potent antibacterial effect against pathogenic bacteria Escherichia coli and did not show haemolytic activity against human erythrocyte. The general antimicrobial mechanism of AMP is to disrupt the cell membrane, however, LBLP exerted its antibacterial activity by causing apoptosis-like death through reactive oxygen species (ROS) generation. LBLP-treated E. coli cells exhibited hallmarks of apoptosis, such as membrane depolarization, DNA fragmentation, caspase-like protein activation and phosphatidylserine exposure. These apoptotic features were attenuated by pretreatment of NAC, a representative ROS scavenger. CONCLUSION
