<abstract xmlns="http://www.w3.org/1999/xhtml">In recent years, there have been notable increas in the occurrence of emerging and reemerging infectious diseases. Most have resulted from the crossing of species barriers from animals to humans, especially from wildlife reservoirs. These threats draw attention to the changing patterns of diseases on a global scale and raise the need for a new worldwide strategy for expanding interdisciplinary collaborations and communications in all aspects of health care for humans, animals and the environment. The most commonly used term for this concept is ‘One Health’. Its origin lies in pre-modern medicine and refers to the idea of One Medicine which means that there is no difference between humans and animals when it comes to the approach to health and disease. The creation of veterinary schools across Europe in the late 18th and 19th centuries is portrayed as a break with the past, in which a new enlightened approach to animal healing superseded that of ignorance and cruelty. At the end of the 19th century, discovery upon discovery was rapidly made in the domain of bacteriology and immunology. Animal diseases were first studied, and veterinary medicine and veterinary bacteriology was closely linked with these findings. Throughout the 20th and 21st centuries, ‘One Health’ concept broke new ground in its concern with the environmental and wildlife aspects of health. This change in thought pattern has been fueled by a number of high-profile international infectious disease events over the past decades. To continue the implementation of the ‘One Health’ idea, the next generation of infectious disease specialists needs to be acquainted not only with modern diagnostic technics, but also equipped to understand disease pathogenesis and the basic principles underlying disease control.1.

<abstract xmlns="http://www.w3.org/1999/xhtml">The presence of <italic>Listeria</italic> rods, especially <italic>Listeria monocytogenes,</italic> in the environment and food products, contributes each year to death of both humans and animals. The ability of bacteria to lead a saprophytic and parasitic existence as well as insensitivity to many physicochemical factors greatly facilitates the spread and guarantees access to a wide range of vulnerable organisms. Although the factors predisposing to infection result in a relatively low incidence of disease, infections are characterized by high mortality and often the need of hospitalization. The disease most often manifests itself in the form of bacteremia, meningitis and encephalitis as well as perinatal infections. The way <italic>Listeria</italic> spreads in the body contributes to the identification of new types of the disease. Recent studies on the acquisition of pathogenicity traits, dose and development of antibiotic resistance as well as numerous reports on incidence of these bacteria and the epidemics they caused, have led to more efficient monitoring of the pathogen . The qualification of the disease has also changed and, currently, listeriosis is considered a contemporary threat to life and health.1. Introduction. 2. Genus <italic>Listeria</italic>.

<abstract xmlns="http://www.w3.org/1999/xhtml">The genus <italic>Alicyclobacillus</italic> includes Gram-positive, Gram-negative or Gram-variable, acidothermophilic, endospore-forming bacteria, which have been isolated from various environments, mostly acidic and geothermal soils, hot springs, fruit surface and spoiled fruit juices. The members of the <italic>Alicyclobacillus</italic> genus are characterized by the presence of ω-alicyclic fatty acids (ω-cyclohexane or ω-cycloheptane), the iso and anteiso branched-chain fatty acids, and the hopanoids as the major membrane lipids. There are 23 known species and 2 subspecies, with <italic>Alicyclobacillus acidoterrestris</italic> as the most significant. Certain species cause food spoilage in the fruit- and-vegetable juices industry. The spores of <italic>Alicyclobacillus</italic> are highly tolerant to high temperatures and low pH-values of fruit juices. What is more, they are naturally present on fruit surface and can readily enter the production environment of the fruit and vegetable processing. Due to high thermophilicity of these bacteria, the typical juice pasteurization conditions can stimulate spore germination. This is the reason why they can proliferate in juice and ipso facto cause fruit products spoilage. The family of <italic>Alicyclobacillaceae</italic> has continuously been modified and each successive year brings new species. Additionally, <italic>A. acidoterrestris</italic> is recognized as bacterium with a high evolution rate due to its rapid adaptation to changing environmental conditions.1. Introduction. 2.

<abstract xmlns="http://www.w3.org/1999/xhtml">The Orthomyxoviruses is a family of viruses with its most common representatives being the influenza viruses (A, B, C and D types), which constitute a significant clinical problem. Influenza is a disease affecting animals and people. It is transmitted by airborne droplets and manifestes itself with such symptoms as coughing, sneezing, muscle pain or fever. Influenza often leads to complications, including pneumonia and myocarditis. In the past, influenza viruses were responsible for pandemics, including the most infamous pandemic of the Spanish influenza. It took place in the years 1918–1919 and is thought to have been responsible for the death toll of as many as 100 million people. The family also includes <italic>Isavirus</italic>, responsible for fish anaemia, <italic>Quaranjavirus</italic> and <italic>Thogotovirus</italic>, among which there also species causing diseases in humans. For example, a human infection with the Bourbon virus was diagnosed only once, in 2014. These viruses are much more rare then influenza viruse and also less known. New species are still discovered.1.

<abstract xmlns="http://www.w3.org/1999/xhtml">Human herpes virus type 4 (HHV-4), commonly known as Epstein-Barr virus (EBV), and human herpes virus type 8 (HHV-8) are members of <italic>Gammaherpesvirinae</italic> subfamily. They both develop latent infections in B lymphocytes. Infection with these viruses in immunocompetent patients is usually mild and self-limiting, but it can have more severe course in immunocompromised individuals. Failure of the immune system often leads to oncogenesis related to gammaherpetic infection. Thus, immunocompromised patients are far more likely to develop proliferative diseases caused by EBV or HHV-8. This problem also applies to HIV-positive individuals coinfected with EBV or HHV-8. Gammaherpesviruses can also be the cause of post-transplantation issues in patients on immunosuppressive drugs and EBV is known to induce severe clinical syndromes in people with specific genetic disorders. Presented article summarizes epidemiology, pathogenesis, clinical syndromes and treatment of EBV and HHV-8 in individuals with immunological disorders.1. Introduction. 2.

<abstract xmlns="http://www.w3.org/1999/xhtml">Rotavirus (RV) infections are a major epidemiological problem in humans and farm animals. So far, a number of human and animal RV strains have been identified. Based on the antigenic properties of the VP6 capsid protein, they have been classified into eight serogroups (A-H). The most important of them are viruses from group A (RVA), which are responsible for more than 90% of cases of rotaviral diarrhoea. The segmented structure of the virus genome and the presence of animals in human neighbourhood favour genetic reassortment between RV strains originating from different hosts. This could result in an emergence of zoonotic virus strains. The increasing number of human infections caused by virus strains having genotypes which have only been identified in animals indicates the need for epidemiological surveillance of infections. Additionally, the identification of epidemic virus strains in the outbreaks of disease in humans should be conducted. The identification of RVA strains circulating in humans and animals will allow the assessment of the impact of vaccination on the selection and emergence of zoonotic RVA strains.1. Introduction. 2. General characteristics and classification of rotaviruses. 3. Group A rotavirus infection in humans. 4. Group A rotavirus infection in animals. 5.

<abstract xmlns="http://www.w3.org/1999/xhtml">Discovering interactions between the etiology of the infection and diabetic patients’ immune system activity may be essential for the relevant clinical diagnosis. The dynamics of colonization of the nasal vestibule by <italic>Staphylococcus aureus</italic> and the development of the prevention strategies against infection are different for various populations. Moreover, the colonization of the nasal vestibule might involve both molecular and epidemiological ctorsfa. Researchers have reported that the identification of methicillin-resistant strains <italic>S. aureus</italic>(MRSA) with similar molecular characteristics allows to assess the ability of the microorganism to spread and the risk of infection in diabetic patients. Knowledge of these characteristics allows to take precautions in patients exposed to <italic>S. aureus</italic>. <italic>S. aureus</italic> is an ethiological factors of many severe diseases both in people with weakened immune system and in healthy individuals. Usually, excess weight and obesity contribute to the incidence of diabetes mellitus type 2 (DM2). However, the colonization by <italic>S. aureus</italic> is a probable risk factor for infection. Among <italic>S. aureus</italic> virulence factors, superantigens (SAgs) are essential for pathogenicity. The long-term effect of the superantigen toxic shock syndrome toxin-1 (TSST-1) might be glucose intolerance. This toxin also induces systemic inflammation as a result of the increased exotoxin concentration in blood, and, therefore, may be the causative factor of diabetes. Chronic exposure to staphylococcal superantigens may contribute to the development of diabetes, suggesting a need to conduct targeted therapies against <italic>S. aureus</italic> superantigens.1.

<abstract xmlns="http://www.w3.org/1999/xhtml">The molecular typing methods are used to identify specific genetic targets and relationships between microbial isolates. In order to understand clonal relatedness between the microbial strains, classic phenotypic methods are used in line with modern molecular biology techniques. The development of genetics, especially new techniques like molecular typing, have revolutionized microbial research. After 1970, the development techniques, especially those referring to DNA sequencing, established molecular microbiology, thus providing modern tools for the identification of sources and routes of infection. Whole genome sequencing and other high-throughput typing methods are becoming increasingly popular and, thanks to their high resolution, they are ideal tools for comparative analysis of bacteria. This study reviews the methods most commonly used in the molecular typing of bacteria, including those which are in the development stage and may be the main tool in microbial typing in the future.1.

<abstract xmlns="http://www.w3.org/1999/xhtml">Soil microbiome is composed of groups of microorganisms which are structurally and functionally very different. For many years soil microbiome has been the subject of numerous studies, but still is not fully recognized. It is well known that soil microorganisms play a key role in biogeochemical processes. Knowledge of their structural and functional diversity makes it possible to assess the condition of the soil environment, which is extremely important for agronomy and ecology. The agricultural and industrial activities of humans cause changes in soil activity, which should be monitored. There are many different research methods developed to analyze soil activity and microbiological soil diversity and refined by researchers from around the world in. Biochemical methods used to analyze microbial activity are based on the determination of the ability of microorganisms to synthesize, assimilate or decompose specific chemical compounds, as well as on the analysis of microbial cell components. This study presents the research methods used for the analysis of both: the functionality of microorganisms and their structural diversity.1. Introduction. 2. Determination of enzymatic activity. 3.

Advancements of Microbiology

 The Advancements of Microbiology (formerly Postępy Mikrobiologii) is a quarterly of the Polish Society of Microbiologists. The journal was founded in 1961, initially under the patronage of the Microbiology Committee of the Polish Academy of Sciences, and in 1989 it became the organ of the PSM. The following professors have served as Editors-in-Chief of Postępy Mikrobiologii during the period: Prof. Edmund Mikulaszek 1962 – 1972, Prof. Władysław Tomasz Dobrzański 1972 – 1982, Prof. Zdzislaw Ilczuk 1983 – 1991, Prof. Jerzy Hrebenda 1991 – 2009, Prof. Jacek Bielecki 2009 – 2022. Journal implements the Society’s main goals, like promoting the development of microbiological sciences, popularizing the achievements of microbiology among members of the Society and broad circles of readers.   Advancements of Microbiology is topical journal for scientists in several microbiological fields and often the place where the first works of young researchers are published. Advancements of Microbiology include review articles from all areas of microbiology that are not printed in other journals. Please send manuscripts with attachments to the editor's e-mail address: editorial.office@am-online.org   Due to the great thematic diversity of the articles sent to the editorial office, it is not possible to print monographic volumes. Most of the papers currently published in Advancements of Microbiology are review articles in the field of bacterial physiology, microbial genetics, environmental microbiology, applied microbiology and virology; the work in the field of epidemiology, classification and identification of bacteria and applications of molecular biology techniques in microbiological research are particularly extensive.   The editors of Advancements of Microbiology strive to print works – ordered by eminent scientists – regarding currently fashionable problems of modern science. We especially encourage Authors to write articles in the field of their expertise, which guarantees the highest scientific level. The high scientific level of the journal was reflected in the progress of the JCR citation index and the presence of our journal on the Philadelphia list. It is especially important for young Authors, for whom Advancements of Microbiology often open the way to a scientific career. The current activity of Advancements of Microbiology is based mainly on publishing reviews related to the latest scientific achievements in the field of microbiology, which, at present is characterized by unusual dynamics of development and comprehensive application possibilities. The selection of current and relevant research topics and their presentation at a high scientific level in our journal is the basis for the existence of the quarterly, Advancements of Microbiology.

Professor Odo Feliks Kazimierz Bujwid (1857 – 1942) – was the first Polish bacteriologist, who graduated from the University of Warsaw and gained experience in Berlin working with Robert Koch, and in Paris at the Ludwik Pasteur Institute.   The Polish Society of Microbiologists (PSM), formerly the Polish Society of Microbiologists and Epidemiologists, was established in Warsaw on October 31, 1927 at the first Congress of Polish microbiologists. Professor Zygmunt Szymanowski was elected the first President of PSM. The same year, PSM also became cofounder of Federation of European Microbiological Societies (FEMS) and since 2005 PSM is a member of European Society of Clinical Microbiology and Infectious Diseases (ESCMID).   Within over 95 years of activity, 29 Congresses of PSM were organized and 16 professors were elected as Presidents of PSM. About 900 ordinary members and 19 honorary members, associated in 14 PSM branches all over Poland, belong to the Society.   The aims of PSM have been the same since its very beginnings: to promote the development of microbiological sciences and to popularize the achievements of microbiology among the Society’s members and the broad public. PSM organizes congresses, scientific meetings, courses and lectures and competitions of scientific papers. Two quarterly journals, the Polish Journal of Microbiology and the Advancements in Microbiology are issued by PSM. The Society formulates opinions on the conditions and needs of Polish microbiology and applies in these cases to the state authorities; cooperates with related associations in the country and abroad.   Archiving   Sciendo archives the contents of this journal in Portico – a digital long-term preservation service of scholarly books, journals and collections.
