Opis:
The „golden age” of antibiotics seems to be coming to an end. The effect of uncontrolled distribution of chemotherapeutic agents in animal production is the commonly growing phenomenon of dramatic drug resistance in bacterial populations. At the end of the 20th century, the repeated failures to effectively control of bacterial infections have initiated the introduction of legislative procedures to limit the use of antibiotics, especially as feed additives in animals. The next step was the developing of alternative for antibiotics to control bacteria, with particular emphasis on natural substances as extracts and oils obtained from plants, which have been used against Gram – positive and Gram – negative bacteria, as well as Candida fungi. These are cationic peptides stabilized by cysteine (defensins and cathelicidins) – identified both in prokaryotes and eukaryotes. Other examples are the nanoparticles, especially silver, gold or platinum. The use of bacteriophages as natural anti-bacterial agents, which bactericidal effect has been demonstrated in numerous experimental therapies in humans and animals, also deserves special emphasis. In this article scientific approaches to novel antibacterial therapies were presented and briefly discussed. As a consequence of the threat of widespread and global growth of multi-resistant bacteria there is a strong need to develop of alternative for antibiotics in elimination of multidrug resistant pathogens.

Opis:
Antimicrobial peptides occupy a prominent place in the production of pharmaceuticals, because of their effective contribution to the protection of the immune system against almost all types of pathogens. These peptides are thoroughly studied by computational methods designed to shed light on their main functions. In this paper, we propose a computational approach, named the Polarity Profile method that represents an improvement to the former Polarity Index method. The Polarity Profile method is very effective in detecting the subgroup of antibacterial peptides called selective cationic amphipathic antibacterial peptides (SCAAP) that show high toxicity towards bacterial membranes and exhibit almost zero toxicity towards mammalian cells. Our study was restricted to the peptides listed in the antimicrobial peptides database (APD2) of December 19, 2012. Performance of the Polarity Profile method is demonstrated through a comparison to the former Polarity Index method by using the same sets of peptides. The efficiency of the Polarity Profile method exceeds 85% taking into account the false positive and/or false negative peptides.
