Whole genome sequencing of a novel Pseudomonas aeruginosa temperate bacteriophage PaP3 has been completed. The genome contains 45 503 bp with GC content of 52.1%, without more than 100 bp sequence hitting homologue in all sequenced phage genomes. A total of 256 open reading frames (ORFs) are found in the genome, and 71 ORFs are predicated as coding sequence(More)
We isolated and characterized a new Pseudomonas aeruginosa myovirus named PaP1. The morphology of this phage was visualized by electron microscopy and its genome sequence and ends were determined. Finally, genomic and proteomic analyses were performed. PaP1 has an icosahedral head with an apex diameter of 68-70 nm and a contractile tail with a length of(More)
Peptide antibiotics are small peptides encoded by organism genomic DNA. They are recognized to play important roles in the innate host defense of most living organisms. The growing resistance of bacteria to conventional antibiotics and the need for discovery of new antibiotics have stimulated great interest in the development of peptide antibiotics as human(More)
MmP1 (Morganella morganii phage 1) is a lytic bacteriophage newly isolated from the host bacterium M. morganii. The entire genome was sequenced, and final assembly yielded a 38,234bp linear double-stranded DNA (dsDNA) with a G+C content of 46.5%. In the MmP1 genome, 49 putative genes, 10 putative promoters and 2 predicted sigma-independent terminators were(More)
Bacteria develop a broad range of phage resistance mechanisms, such as prevention of phage adsorption and CRISPR/Cas system, to survive phage predation. In this study, Pseudomonas aeruginosa PA1 strain was infected with lytic phage PaP1, and phage-resistant mutants were selected. A high percentage (~30%) of these mutants displayed red pigmentation phenotype(More)
Terminase proteins are responsible for DNA recognition and initiation of DNA packaging in phages. We previously reported the genomic sequence of a temperate Pseudomonas aeruginosa phage, PaP3, and determined its precise integration site in the host bacterial chromosome. In this study, we present a detailed functional identification of the DNA packaging(More)
Natural antisense transcripts (NATs) are naturally widespread and have very important functions in regulating expression of their target genes. In this report, we identified a novel NAT, designated mucD-AS, transcribed from the opposite strand of mucD gene locus, which has a pivotal function in regulating the biosynthesis of alginate. For the(More)
Whole-genome sequencing is an important method to understand the genetic information, gene function, biological characteristics and survival mechanisms of organisms. Sequencing large genomes is very simple at present. However, we encountered a hard-to-sequence genome of Pseudomonas aeruginosa phage PaP1. Shotgun sequencing method failed to complete the(More)

In this work, we present a social network spam detection application based on texts. Particularly, we tested on the Facebook spam. We develop an application to test the prototype of Facebook spam detection. The features for checking spams are the number of keywords, the average number of words, the text length, the number of links. The data mining model(More)
BACKGROUND Schistosomiasis japonica is a zoonotic parasitic disease; developing transmission blocking veterinary vaccines are urgently needed for the prevention and control of schistosomiasis in China. Heterologous prime-boost strategy, a novel vaccination approach, is more effective in enhancing vaccine efficacy against multiple pathogens. In the present(More)
