[Investigation on Angiostrongylus cantonensis Infection in Rodents in Zhangzhou City, Fujian Province].

Objective: To investigate the Angiostrongylus cantonensis infection in rodents in Zhangzhou City and provide basis for control the disease.

Methods: Eighteen villages in 4 counties, which located in coastal and mountain regions of rodent breeding, were selected between 2013-2015. Rodents were collected by cage trapping, and organs of heart and lungs were prepared for microscopic examination of A.

PTreeRec: Phylogenetic Tree Reconstruction based on genome BLAST distance.

Phylogenetic Tree Reconstruction (PTreeRec) is a web-based tool for automatic phylogeny inferences from whole-genome sequences, which accepts files of DNA sequences in the FASTA format and allows users to save the output tree file, and displays the inferred tree through an applet in a web browser. PTreeRec involves three basic steps. First, regions of maximal segment pairs (MSPs) based on an all-against-all pairwise comparison of genomes are located.

Genome-based phylogeny of poxvirus.

A comprehensive phylogenetic analysis of Poxviridae was performed in this study. Phylogenetic trees were reconstructed from whole genomic information including gene order, gene content, and all conserved gene protein sequences. Gene content and gene order were the methods used for the first time in cladogram reconstruction of poxvirus.

Analysis and prediction of baculovirus promoter sequences.

Consensus patterns of baculovirus sequences upstream from the translational initiation sites have been analyzed and a web tool, Local Alignment Promoter Predictor (LAPP), for the prediction of baculovirus promoter sequences has also been developed. Potential consensus sequences, i.e.
