Virulence Mechanisms of Acinetobacter

Draft Genome Sequence of Acinetobacter sp. Strain VT-511 Isolated from the Stomach of a Patient with Gastric Cancer

We report the draft genome sequence of Acinetobacter sp. strain VT-511, which was obtained from the stomach of a patient with gastric cancer. The genome of Acinetobacter sp. VT-511 is composed of approximately 3,416,321 bp and includes 3,214 predicted protein-coding genes.

In silico analysis of Acinetobacter baumannii phospholipase D as a subunit vaccine candidate

The rate of human health care-associated infections caused by Acinetobacter baumannii has increased significantly in recent years for its remarkable resistance to desiccation and most antibiotics. Phospholipases, capable of destroying a phospholipid substrate, are heterologous group of enzymes which are believed to be the bacterial virulence determinants. There is a need for in silico studies to identify potential vaccine candidates. A. baumannii phospholipase D (PLD) role has been proved in increasing organism's resistance to human serum, destruction of host epithelial cell and pathogenesis in murine model. In this in silico study high potentials of A. baumannii PLD in elicitation of humoral and cellular immunities were elucidated. Thermal stability, long half-life, non-similarity to human and gut flora proteome and non-allergenicity were in a list of A. baumannii PLD positive properties. Potential epitopic sequences were also identified that could be used as peptide vaccines against A. baumannii and various other human bacterial pathogens.
