Pseudomonas aeruginosa is one of the most widespread and troublesome opportunistic pathogens that is capable of colonizing various human tissues and organs and is often resistant to many currently used antibiotics. This resistance is caused by different factors, including the acquisition of specific resistance genes, intrinsic capability to diminish(More)
Reconstruction of phylogeny of a protein family from a sequence alignment can produce results of different quality. Our goal is to predict the quality of phylogeny reconstruction basing on features that can be extracted from the input alignment. We used Fitch-Margoliash (FM) method of phylogeny reconstruction and random forest as a predictor. For training(More)
Persistence is a form of interaction of pathogenic bacteria with a host aimed to promote their long-term survivalby means of inactivation of the host's protective systems via modulation of intracellular signal pathways. Persistent forms of a pathogen are refractory to traditional antibiotic therapy and cause chronic infectious diseases. Directed search for(More)
Listeria monocytogenes is a causative agent of foodborne infection in humans and animals. The virulence factor InlB interacts with mammalian receptor c-Met via its internalin domain to provide L. monocytogenes invasion in non-professional phagocytes. Naturally occurring InlB internalin domain variants form four subclusters on the maximal likelihood tree.(More)
Comparison of several protein phylogeny reconstruction methods was realized on a set of natural protein sequences. The programs of the PHYLIP package and FastME, PhyML and TreeTop programs were tested. In contrast to several studied programs that used simulated sequences, our results demonstrate the superiority of distance methods over the maximum(More)
