Enterobacter hormaechei is a foodborne pathogen responsible for neonatal sepsis in humans and respiratory disease in animals. In this work, a new virulent phage (P.A-5) infecting E. hormaechei was isolated from domestic sewage samples and characterized. Transmission electron microscopy revealed that P.A-5 belonged to the family Myoviridae having a head size of 77.53 nm and a tail length of 72.24 nm. The burst size was 262 PFU/cell after a latent period of 20 min. Phage P.A-5 was able to survive in a pH range of 4-9 and resist temperatures up to 55 °C for 60 min. The genome sequence of P.A-5 had homology most similar to that of Shigellae phage MK-13 (GenBank: MK509462.1). Pork artificially contaminated with E. hormaechei was used as a model to evaluate the potential of P.A-5. The results clearly showed that P.A-5 treatment can completely inhibit E. hormaechei growth in pork within 8 h, indicating the potential use of P.A-5 as a biocontrol agent for E. hormaechei.

Software program for phylogenetic analyses of large datasets under maximum likelihood.
View all literature mentionsSoftware providing de novo, parallel, paired-end sequence assembler that is designed for short reads. ABySS 1.0 originally showed that assembling human genome using short 50 bp sequencing reads was possible by aggregating half terabyte of compute memory needed over several computers using standardized message passing system. ABySS 2.0 is Resource Efficient Assembly of Large Genomes using Bloom Filter. ABySS 2.0 departs from MPI and instead implements algorithms that employ Bloom filter, probabilistic data structure, to represent de Bruijn graph and reduce memory requirements.

View all literature mentionsSoftware package for ab initio identification of protein coding regions in RNA transcripts. Algorithm parameters are estimated by unsupervised training which makes unnecessary manually curated preparation of training sets. Sets of assembled eukaryotic transcripts can be analyzed by modified GeneMarkS-T algorithm which part of gene prediction programs GeneMark.
