VACCINES AGAINST ROTAVIRUS INFECTION

Marta Prygiel/ Klaudia Brodzik/ Aldon Wiatrzyk/ Małgorzata Główka/ Katarzyna Woźnica/ Karol Wdowiak/ Urszula Czajka/ Aleksandra A. Zasada

Rotavirus infections are a leading cause of severe gastroenteritis in children under five years of age. Before the introduction of vaccination for rotavirus,100–150 million cases of infections were recorded globally, resulting in 500 000 deaths. The first rotavirus vaccines were designed in the 1980s. In 2007, two oral rotavirus vaccines containing live attenuated strains were registered in Europe: the monovalent vaccine Rotarix (RV1) and the pentavalent vaccine Rotateq (RV5). The vaccines are a(..)

NON-ANTIBIOTIC USE OF ANTIBIOTICS

Maciej Danielewski/ Dorota Ksiądzyna/ Adam Szeląg

Antibiotics are widely used medicines in the treatment of infectious diseases. However, some of them show also non-antibiotic properties, which are increasingly used in the treatment of non-infectious diseases. The authors of this publication believe that this is one of the reasons behind antibiotic dissemination in the environment and, ipso facto, behind the increasing risk of bacterial resistance. It is worth remembering that, along with the progress in science and better knowledge of the new (..)

DANGER THEORY AND DAMAGE - ASSOCIATEDMOLECULAR PATTERN

Agata Poniewierska-Baran/ Beata Tokarz-Deptuła/ Wiesław Deptuła

The immune system of mammals has developed many mechanisms to effectively defend itself against foreign factors, including pathogens. In 1994, Polly Matzinger published a theory of danger, a new view in immunology, describing the response of the immune system to danger, caused by trauma and/or presence of pathogens. This theory sheds a different view on the current belief, that the immune system distinguishes between own (self) and foreign (non-self) structures and reacts only to non-self factor(..)

FROM A COMMENSAL TO A PATHOGEN – TWO FACES OFSTAPHYLOCOCCUS EPIDERMIDIS

Beata Podgórska/ Danuta Kędzia

Staphylococcus epidermidis is a commensal organism and the most abundant constituent of the healthy human skin and mucous membrane microbiota. It is well adapted to colonize and evade human antimicrobial barriers. Staphylococcus epidermidis not only competes with potentially harmful pathogens, but also produces a plethora of proteins supporting host natural defenses. At the same time, Staphylococcus epidermidis is an opportunistic pathogen recognized as one of the leading causes of healthcare-as(..)

STAPHYLOCOCCUS EPIDERMIDISAS A CAUSATIVE AGENTOF HEALTHCARE - ASSOCIATED INFECTIONS

Beata Podgórska/ Danuta Kędzia

Healthcare-associated infections and antimicrobial resistance are two of the most important threats in the contemporary medicine, representing a serious burden for the public health system. Previously regarded only as an innocuous commensal microorganism of human skin, S. epidermidis is nowadays seen as an important opportunistic pathogen and the most frequent cause of nosocomial infections. S. epidermidis is the most genetically diverse species within the genus Staphylococcus. Strains belonging(..)

TYPE VB AND VI SECRETION SYSTEMS AS COMPETITION AGENTS OF GRAM-NEGATIVE BACTERIA

Dawid Gmiter/ Grzegorz Czerwonka/ Wiesław Kaca

Bacterial competition, defined as a local neighbour interaction, can lead to competitors’ coexistence, bacterial community self-organization or rearrangement of species dominance structure in ecological niches. Bacteria developed many mechanisms to communicate and compete. Kin discrimination mechanisms in bacterial populations allow species to distinguish a friend from a foe in bacterial environment. Type Vb and VI secretion systems (TVIbSS and TVISS) play a crucial role in this phenomenon. A co(..)

CHARACTERISTICS AND FUNCTIONS OF HYDROPHOBINSAND THEIR USE IN MANIFOLD INDUSTRIES

Łukasz P. Tymiński/ Zuzanna Znajewska/ Grażyna B. Dąbrowska

Hydrophobins are surface active proteins produced by filamentous fungi. They play a role in fungal growth and their life cycle. Proteins with similar properties have been also found in prokaryotic organisms. Hydrophobins are characterized by a specific arrangement of cysteine residues, which form four disulfide bridges in the amino acid sequence. This construction gives hydrophobins their hydrophobic properties, allowing for their spontaneous assembly into amphipathic monolayers at hydrophobic-h(..)

THE RISK OF DISEASES TRANSMITTEDBY INSECT VECTORS IN ANIMALS IN EUROPE

Katarzyna Krasoń/ Magdalena Larska

Currently, the emergence of exotic diseases in areas where they have not previously occurred is reported more frequently. For this reason, the World Organization for Animal Health (OIE) and individual countries are introducing regulations aimed at preventing and combating these diseases. Globalization and intensification of the trade of animals and food products of animal origin contributes to the transmission of infectious animal diseases throughout the world. Global warming and human interfere(..)

INDUSTRIAL APPLICATIONS OF WILD AND GENETICALLY-MODIFIED STRAINS OF ACETIC ACID BACTERIA

Lidia Stasiak-Różańska/ Milena Kupiec

Acetic Acid Bacteria (AAB) have been known for many years, since humans first used them to produce vinegar. AAB serve as biocatalysts in industrial production of, inter alia, acetic acid, dihydroxyacetone, gluconic acid, bacterial cellulose or levan. Apart from the traditional industrial applications of wild strains of AAB, scientists strive to develop novel methods for the production of selected compounds using genetically-modified AAB. The application of such mutants in the industry entails bo(..)
