Human-associated bacteria and their mobile genetic elements - important minority in wastewater and wastewater impacted ecosystems
PublicationSince human-associated bacteria have been recognized as vectors in two - way gene transmission between the pathogenic and environmental populations, health hazard connected with wastewater discharge requires reevaluation. In this paper the particular attention was given to antimicrobial-resistance of Escherichia coli and enterococci isolated from wastewater and wastewater impacted environments. The obtained results showed that...

A new division of bacterial UvrA homologues
PublicationThe UvrA protein is a DNA-binding and damage-recognition enzyme which participates in the prokaryotic type nucleotide excision repair (NER) pathway. It has recently been noted that some bacterial genomes comprise additional uvrA genes which encode five distinct types of UvrA homologue. We investigated the sequences of over 2400 bacterial genomes and found 130 examples of bacteria containing uvrA 2 genes. The sequence analyses conducted...

Genetic and Epigenetic Aspects of Atopic Dermatitis
PublicationAtopic dermatitis is a heterogeneous disease, in which the pathogenesis is associated with mutations in genes encoding epidermal structural proteins, barrier enzymes, and their inhibitors; the role of genes regulating innate and adaptive immune responses and environmental factors inducing the disease is also noted. Recent studies point to the key role of epigenetic changes in the development of the disease. Epigenetic modifications...

Cold-adapted bacterial lipolytic enzymes and their applications
PublicationLipolytic enzymes, esterases and lipases catalyze the hydrolysis and transesterification of fatty acid esters. This class of enzymes is the most important group of biocatalysts for biotechnological applications. From this perspective, coldactive lipolytic enzymes from cold adapted bacteria display attractive properties for some industrial purposes, including high catalytic activity at low temperatures and low thermostability. To...

Application of genetic algorithms in graph searching problem
PublicationGraph searching is a common approach to solving a problem of capturing a hostile intruder by a group of mobile agents. We assume that this task is performed in environment which we are able to model as a graph G. The question asked is how many agents are needed to capture an arbitrary fast, invisible and smart intruder. This number is called the (edge) search number of G. The strategy which must be performed by agents is called...

Genetic features of clinical Pseudomonas aeruginosa strains
PublicationW grupie 62 izolatów klinicznych sprawdzono obecność 6 wybranych czynnikow wirulencji. We wcześniejszych badaniach z wykorzystaniem techniki ERIC - PCR wykazano, że w analizowanej grupie 49 (79%) to szczepy, o dużum podobieństwie genetycznym (ponad 62%), każdy z pozostałych 13 izolatów zaliczono do osobnego genotypu, o zdecydownie niższym stopniu pokrewieństwa. W przypadku wszystkich 49 szczepów z pierwszej grupy stwierdzono obecność...
