CRESOLS AND THE MICROORGANISMS OF THE SOIL ENVIRONMENT

Magdalena Zaborowska

Phenolic compounds, including cresols, in the soil environment are a result of natural processes such as: biodegradation of lignins and tannins, and anthropogenic activity. Cresols are present in disinfectants as well as in the wastewater from chemical, petrochemical, pharmaceutical, paper and textile industry. They are also used in the production of insecticides, herbicides, medicines and antioxidants and have been classified as hazardous substances. Exposure of microorganisms to cresols can br(..)

PROBIOTICS AND THEIR POTENTIAL ANTIOXIDATIVE ACTIVITY

Nina Trojan/ Paweł Satora

Human population in the XXI century is struggling with the increasing incidence of such diseases as obesity, diabetes, cancers, food allergies and many others. Recent studies have shown that oxidative stress caused by reactive oxygen species and free radicals, may underlie the occurrence of many diseases. Probiotics are known for their beneficial effects on health and are established as dietary adjuncts. Researchers are trying to find potential probiotic strains which can exhibit antioxidant pro(..)

SPECIES DIVERSITY OF BACTERIA ASSOCIATED WITH FUNGI OF THE GENUS TUBER (TRUFFLES)

Marta Siebyła/ Dorota Hilszczańska

Truffles (Tuber spp.) are ascomycete hypogeous fungi, which form ectomycorrhizae with roots of trees, shrubs and herbaceous plants. Their fruiting bodies are valued for their distinctive aroma. The aroma might be partially due to complex bacterial community which colonizes their fruiting bodies. Some bacterial species are also believed to promote the truffle’ fruitification due to the fixation of nitrogen inside the developing truffles. Although truffles, especially of the species Tuber aestivum(..)

THE HUMAN MICROBIOME

Magdalena Malinowska/ Beata Tokarz-Deptuła/ Wiesław Deptuła

The human microbiome is represented by bacteria, archea, viruses, including bacteriophages, and fungi. These microorganisms colonize the human body and are necessary for the maintenance of homeostasis, including human immune status. Even though human microbiome is vital for the functioning of the human organism, it is still poorly understood, especially when it comes to archea, but also viruses and fungi. The aim of this study is to present the current state of knowlegde about the microorganisms(..)

APPLICATION OF THE BACTERIAL OUTER MEMBRANE VESICLES IN VACCINE DESIGN

Joanna Jadwiga Klim/ Renata Godlewska

Outer membrane vesicles (OMVs) are extracellular structures produced by most gram‑negative bacteria, including pathogens of humans and animals. OMVs play an important role in the physiology of microorganisms and are an integral part of many biological processes. Following the discovery that they are able to transport many biomolecules, also these which have the ability to interact with the immune system, their potential use as non‑replicating vaccines has become an important aspect of immunother(..)

FRUCTOPHILIC LACTIC ACID BACTERIA (FLAB) – A NEW GROUP OF HETEROFERMENTATIVE MICROORGANISMS FROM THE PLANT ENVIRONMENT

Klaudia Gustaw/ Magdalena Michalak/ Magdalena Polak-Berecka/ Adam Waśko

Recently, a unique kind of lactic acid bacteria (LAB) i.e. fructophilic lactic acid bacteria (FLAB), has been described. This specific group prefers D-fructose over D-glucose as a carbon source to growth. They can be found in fructose rich environments such as flowers, fruits and food products made of fermented fruits, for example tempoyak. In recent years, it has been revealed that insects which feed on food high in fructose are an abundant source of fructophilic bacteria. Bacterial communities(..)

BACTEROIDES SPP. – CLINICAL SIGNIFICANCE, ANTIBIOTIC RESISTANCE AND IDENTIFICATION METHODS

Sebastian Niestępski/ Monika Harnisz/ Ewa Korzeniewska/ Adriana Osińska/ Bartłomiej Dziuba

Anaerobic Bacteroides species are dominant microbiota of the digestive tract of mammals. Along with other symbiotic bacteria located in the gastrointestinal tract, they contribute to the proper functioning of the organism. Some Bacteroides species are highly pathogenic. Virulence of these bacteria is related to their polysaccharide capsule, lipopolysaccharide and a variety of enzymes and enterotoxin. In recent years, an increase of antibiotic resistance in Bacteroides spp. has been noted, theref(..)

AMYLOIDS, COMMON PROTEINS AMONG MICROORGANISMS

Barbara Katarzyna Pawłowska/ Beata Magdalena Sobieszczańska

Historically, the term amyloid was used strictly with reference to human neurodegenerative diseases. Nowadays, it is known that many proteins have the potential to conformational changes into β-sheet structures with tendency to form insoluble amyloid fibrils. Moreover, amyloid proteins are widespread among microorganisms. Bacteria and fungi produce functional amyloids which exhibit all characteristics of amyloid proteins, but in contrast to a numerous group of human toxic amyloids, they play imp(..)

MECHANISMS OF ARSENIC TOXICITY AND TRANSPORT IN MICROORGANISMS

Seweryn Mucha/ Mateusz Berezowski/ Katarzyna Markowska

Arsenic is an ubiquitous element present in the environment either through geological or anthropogenic activities. Millions of people all over the world are exposed to arsenic mainly via air, drinking water and food sources, which results in higher incidence of cancer. Several mechanisms by which arsenic compounds induce tumorigenesis have been proposed. Arsenic mediates its toxicity by generating oxidative stress, inducing protein misfolding, promoting genotoxicity, hampering DNA repair and dis(..)

FACTORS RESPONSIBLE FOR THE DEVELOPMENT OF LYME CARDITIS

Tomasz Chmielewski/ Stanisława Tylewska-Wierzbanowska

Borrelia burgdorferi sensu lato spirochetes are unique in many aspects. They are the etiological agents of Lyme borreliosis, meta-zoonotic, tick-borne disease of mammals, including humans. Ixodes spp. ticks are the vector. With the exception of erythema chronicum migrant (EM), manifestations of the disease may vary depending on the genospecies of Borrelia burgdorferi sensu lato. One of the symptoms is Lyme carditis. To date, the causative factors and the mechanisms of pathogenesis have not been (..)

PATHOGENIC FREE-LIVING AMOEBA

Natalia Łanocha-Arendarczyk/ Danuta Kosik-Bogacka/ Wojciech Zaorski/ Karolina Kot/ Katarzyna Galant/ Aleksandra Łanocha

Invasions caused by free-living and parasitic limax amoeba can pose a major threat to human health and life. The amoeba from the genera Acanthamoeba and Naegleria as well as the following species: Sappina diploidea, S. pedata, Balamuthia mandrillaris, and probably Hartmannella vermiformis, are the major cause of primary amoebic meningoencephalitis (PAM), granulomatous amebic encephalitis (GAE) and amoebic keratitis (AK). Furthermore, free-living amoeba can be vectors of bacteria, including Legio(..)

ASSESSING BIOCIDAL ACTIVITY OF AGENTS USED IN CHEMICAL-THERMAL DECONTAMINATION OF HOSPITAL TEXTILES IN THE LIGHTOF NEW EUROPEAN STANDARD PN-EN 16616: 2015-10. CHEMICAL-THERMAL DECONTAMINATION OF TEXTILES

Patryk Tarka/ Aneta Nitsch-Osuch/ Krzysztof Kanecki/ Agnieszka Chojecka/ Olga Paduch

Appropriate decontamination of hospital textiles depends heavily on specifically defined proceedings for handling decontaminated hospital textiles (collection, segregation, packing, transportation) and appropriate disinfection in the laundry process. It is becoming increasingly common to disinfect hospital textiles in a chemical-thermal process. Disinfectants used in this process should be applied according to functional parameters defined in validated and repeatable test methods. Changes in ass(..)
