Opis:
The present study investigated the drug-resistance to the selected antibiotics in Escherichia coli, Salmonella typhimurium and beta-haemolytic coagulase-positive staphylococci isolated from pigeons bred in Poland. In the case of E. coli, tetracyclines and amoxicillin were least effective. In the staphylococci, the highest resistance was detected for oxytetracycline and quinolones and 5% were resistant to methicillin. The lowest drug-resistance was reported for Salmonella typhimurium.

Opis:
Avian encephalomyelitis (AE) is a viral disease of poultry. Although the disease has a milder clinical course in turkeys than in chickens, reproductive flocks of turkeys are vaccinated against AE. Commercial AE ELISA kits are specifically designed for chickens, which makes it difficult to implement these tests in serological monitoring of turkey flocks. The aim of the study was to compare the AE serological results provided by two ELISA kits from different producers when testing an AE-vaccinated flock of turkey hens and their progeny. We detected differences in the sensitivity of the ELISAs for testing specific anti-AE antibody levels in turkey serum samples.

Opis:
Bordetella avium, the causing agent of bordetellosis, a highly contagious infection of the respiratory tract in young poultry, causes significant losses in poultry farming throughout the world. Wildlife birds can be a reservoir of various pathogens that infect farm animals. For this reason the studies were conducted to estimate the prevalence of Bordetella avium in wildlife birds in Poland. Tracheal swab samples were collected from 650 birds representing 27 species. The bacterial DNA was isolated directly from the swabs and screened for Bordetella avium by TaqMan real-time PCR. The assay specificity was evaluated by testing DNA isolated from 8 other bacteria that can be present in avian respiratory tract, and there was no amplification from non-Bordetella avium agents. Test sensitivity was determined by preparing standard tenfold serial dilutions of DNA isolated from positive control. The assay revealed to be sensitive, with detection limit of approximately 4.07x10^2 copies of Bordetella avium DNA. The genetic material of Bordetella avium was found in 54.54% of common pheasants, in 9.09% of Eurasian coots, in 3.22% of black-headed gulls and in 2.77% of mallard ducks. The results of this study point to low prevalence of Bordetella avium infections in wildlife birds. The results also show that described molecular assay proved to be suitable for the rapid diagnosis of bordetellosis in the routine diagnostic laboratory.

Opis:
The aim of the study was to determine the effect of a Polish low-virulence isolate of haemorrhagic enteritis adenovirus (HEV) on the immune system in turkeys and on the course of colibacillosis in birds infected under laboratory conditions. Turkeys were infected per os with HEV at the dose of 104.3EID50/mL and with E. coli (APEC) (serotypes 078:K80:H9) at the dose of 4×109CFU/mL by injection to the thoracic air sac. The birds infected with the HEV were infected with the APEC either simultaneously or after 5 days. Five days after HEV infection, the percentages of subpopulations of the CD3+CD4+ and CD3+CD8α+ T cells and the IgM+ B cells were determined in blood and spleens of the HEV-infected turkeys and in the control (uninfected) birds. The course of colibacillosis was more severe in turkeys infected with the APEC 5 days after infection with the HEV than in those infected with the HEV and APEC simultaneously and than in those infected only with APEC. Five turkeys out of the 18 infected with the APEC 5 days after infection with HEV, died. Their body weights were statistically significantly lower with higher FCR values 41 days after the infection in comparison to turkeys in the other groups. A considerable decrease in the percentage of the T and B cells subpopulations in the blood were found in turkeys infected with the HEV and while the percentage of CD3+CD4+ T cells subpopulation in the spleen increased significantly, the contribution of the CD3+CD8α+ T cells and IgM+ B cells subpopulations were decreased. These changes in the immune system of turkeys, occurring 5 days after infection with the HEV, made them more susceptible to infection with the APEC.

Opis:
The objective of this study was to determine the effect of whole wheat feeding on selected parameters of humoral and cell-mediated immunity in growing turkeys. A total of 210 one-day-old heavy-type Hybrid Converter male turkeys were randomly divided into three different dietary treatment groups, each consisting of 7 replicate pens of 10 birds per pen. Until 4 wk of age, all birds were fed a commercial diet formulated to meet nutrient requirements. From 5 to 12 wk of age, diets were composed of wheat (ground-pelleted or whole grain) and protein-fat-mineral-vitamin concentrate. The total wheat concentration in diets was 500 or 600 g/kg in the feeding periods of 5-8 and 9-12 wk of birds’ age, respectively. Whole grain wheat had a 0, 50 or 100% share of the total wheat amount in the daily ration in treatment groups W₀, W₅₀ or W₁₀₀, respectively. Commercial vaccines against ND (Newcastle disease) and TRT (Turkey rhinotracheitis) were administered to turkeys via the drinking water on days 20 and 30, respectively. Over the entire experiment, a significant linear decrease was observed in body weight gains (BWG) with increasing dietary levels of whole grain wheat. As a result the BWG of control turkeys (W₀) were significantly higher than the BWG of group W₁₀₀ birds (P = 0.002). A significant linear increase in feed conversion ratio (FCR) was observed with increasing dietary levels of whole grain wheat (P < 0.001). The levels of antibodies against TRT and ND viruses after immunization were significantly higher in both the W₅₀ and W₁₀₀ group, in comparison to group W₀ (P = 0.006 and P = 0.001, respectively). Turkeys from group W₅₀, in comparison to those from groups W₀ and W₁₀₀, had a significantly higher percentage of CD4⁺ T cell subpopulation within the lymphocytes isolated from blood and ileal mucosa, as well as CD4⁺ CD8⁺ and CD8⁺ T cell subpopulations within the blood immunocompetent cells (P = 0.022, P = 0.029, P = 0.009 and P = 0.011, respectively). In the cecal tonsils, the percentage of CD8⁺ T cell subpopulation was significantly lower in group W₅₀ than in groups W₀ and W₁₀₀ (P = 0.014). The results of our study indicate that diluting diets with whole grain wheat stimulates the non-specific cell-mediated defense mechanisms of the gastrointestinal immune system in turkeys, thus positively affecting humoral response after vaccination.

The present study investigated the prevalence of Bordetella avium (BA) infections in turkey flocks of different production type in Poland, based on serological examination of blood samples collected between 2012 and 2014. The results of our study indicate that BA infections are very common in turkey flocks, they are possible during the whole production cycle and that probability of the past infection increases with age. This situation is causing high level of specific anti-BA maternally derived antibody transfer to hatching poults.

Turning requirements into working systems is the essence of software engineering. This paper proposes automation of one of the aspects of this vast problem: generating user interfaces directly from requirements models. It presents syntax and semantics of a comprehensible yet precise domain specification language. For this language, the paper presents the process of generating code for the user interface elements. This includes model transformation procedures to generate window initiation code and event handlers associated with these windows. The process is illustrated with an example based on an actual system developed using the presented approach.

Opis:
The aim of the study was to investigate the possibility of Transmissible Viral Proventriculitis (TVP) occurrence in broiler chickens in Poland. In march 2016 proventriculi samples were collected from broiler chickens showing poor uniformity and decreased body weight, accompanied by enlarged proventriculi. Histopathological examination of affected proventriculi revealed typical lesions associated with TVP (vacuolar degeneration and necrosis of glandular epithelium, replacement of glandular epithelium by hyperplastic ductal epithelium and moderate to severe lymphocytic infiltration). To our best knowledge, up to date there is no report indicating the presence of TVP in Poland nor in Central and Eastern Europe.

Professional qualifications are classified legally and are the same cross the professional spectrum. What factor determines teachers’ didactic, educational and professional aspirations and self-evaluation? Who/what determines that the teacher becomes an (anti)authority for his/her students, can instill their passion for learning or discourage them? When are a teacher’s education and qualifications of less importance than his/her competences? There are teachers for whom work is only an obligation, a duty towards the school, and education is the obligation of a student. They are teachers working with children only because it is their legal duty. But there are also teachers who teach students how to learn, instilling in them educational freedom. These are guide-teachers who reveal their students’ horizons, teaching them to choose a new knowledge that is supposed to give them satisfaction, emotional joy and practical benefits.

Opis:
This review article presents fundamental mechanisms of the local mucosal immunity in selected regions of the respiratory tract in healthy birds and in some pathological conditions. The respiratory system, whose mucosa come into direct contact with microorganisms contaminating inhaled air, has some associated structures, such as Harderian gland (HG), conjunctive-associated lymphoid tissue (CALT) and paranasal glands (PG), whose participation in local mechanisms of the mucosal immunity has been corroborated by numerous scientific studies. The nasal mucosa, with structured clusters of lymphoid tissue (NALT – nasal-associated lymphoid tissue) is the first to come into contact with microorganisms which contaminate inhaled air. Lymphoid nodules, made up of B cells with frequently developed germinal centres (GC), surrounded by a coat of CD4+ cells, are the major NALT structures in chickens, whereas CD8+ cells are situated in the epithelium and in the lamina propria of the nasal cavity mucosa. Studies into respiratory system infections (e.g. Mycoplasma gallisepticum) have shown the reactivity of the tracheal mucosa to infection, despite a lack of essential lymphoid tissue. Bronchus-associated lymphoid tissue (BALT) takes part in bronchial immune processes and its structure, topography and ability to perform defensive function in birds is largely age-dependent. Mature BALT is covered by a delicate layer of epithelial cells, called follicle-associated epithelium (FAE). Germinal centres (GC), surrounded by CD4+ cells are developed in most mature BALT nodules, while CD8+ lymphocytes are dispersed among lymphoid nodules and in the epithelium, and they are rarely present in GC. Macrophages make up the first line of defence mechanisms through which the host rapidly responds to microorganisms and their products in the respiratory mucosal system. Another very important element are polymorphonuclear cells, with heterophils being the most important of them. Phagocytic cells obtained from lung lavages in birds are referred to as FARM (free avian respiratory macrophages). Their number in chickens and turkeys is estimated to be 20 times lower than that in mice and rats, which indicates a deficit in the first-line of defence in the birds’ respiratory system. There are numerous B cells and antibody secreting cells (ASC) present throughout the respiratory system in birds. Their role comes down to perform antigen-specific protection by producing antibodies (IgM, IgY or IgA class) as a result of contact with pathogenic factors.

Opis:
In the contemporary and dynamic educational reality, also known as socialization, a young person (or is it just a young one [sic!]) in a process of gaining experience, instead of understanding the environment better with time, gets lost, has problems with self-determination, struggles between the important and the irrelevant, the desired and the redundant, good and harmful. The wisdom and educational experience, the educational process and recognized educational influences should become helpful. The pragmatism of the theory of cognition often allows for conclusions and reflections on every process of scientific cognition. In the area of axiology, it may constitute a “pillar of pedagogical initiation”. In view of the holistic format of the majority of educational phenomena, the subject as a balanced dialogue and consistent in the autonomy of leadership (especially educational!) fits perfectly well the latest theories and trends of modern pedagogical, psychological and social knowledge as well as theories of inter-/intrapersonal management. The above indications are the basis for a wise leadership in education and an upbringing in leadership. Knowledge of leadership issues, understood as the process of socialization, may wisely support and strengthen educational influences. Otherwise, by unwise influences, from the pedagogical point of view, something can be irretrievably lost and wasted. To understand the phenomenon of leadership, you must first thoroughly analyze the issue of leadership in groups, trying to show relationships with other people in the process. This is vital due to the frequent confusion of the concepts of leadership and management, or leadership and command. Leadership is often recognized via its chief attribute by e.g. persistence of community, debates, personalization of tasks and actions, bonds of belonging, dynamisms of interpersonal relations (atmosphere and culture in task situations) and roles as an axiom of task decision-making.

Opis:
The world of social norms and values is constantly embedded in the teacher’s actions and the educational theories they recognise, in their didactic end educational successes and failures, in professional adaptation and evaluation, in didacticism and educational inspiration, and in the case of a few, in educational leadership deprived of the external and personal world. In every dimension of the teacher’s pedagogical activities there is a link between the acquired theoretical knowledge and the professional attitude. The pedagogical approximation into specific theories and pedagogical ideas is illustrated by the professional attitude of the teacher, interpersonal relations with students and the teaching staff. The knowledge of pedagogical paradigms, the realization of diverse ideas can be a factor in a teacher’s pedagogical success, as there is no single theory, explaining and suitable for a specific school community in the educational space. Contemporary pedagogical theories, like never in the past, are becoming a creator of social mentality in multicultural environments. They are becoming a “civilizational hope” for the reduction of traditional “prescriptive-distributive” thinking, as well as subject-based, directive and authoritarian education, and educational impossibilism in schools. Contemporary pedagogical controversies around the relationship of education and leadership do not have antagonistic content, elements that are pedagogically and socially opposed. They interact with each other in various and multi-level ways in the space of humanistic pedagogy and human resource management, they are a pedagogical dualism in the sphere of descriptive and relational narrative, critical thinking, without space for academic logomachia. The growing interest in the teacher’s autonomy, teacher’s independence, the dimensions of the presence in the pedagogical community, and the pursuit of individual needs are issues of external educational affiliation. What educational and cultural dimension should constitute the pedagogical habitus of a modern teacher? From the content of many pedagogical publications, a conclusion emerges that in education, it is not the teachers who become the motivators of exceeding knowledge and skills for themselves, but the students who exceed their teachers. Such a confrontation of the two worlds: teachers, representing institutionalised education and students (more precisely: learners), having one common goal – mutual understanding, which already requires a change in the generation paradigm, methods of operation, education (students and teachers), modification of the education already acquired, transformation of the model of “becoming” a teacher (usually based on authority – still traditional) more effectively appealing to students and systematic use of the new technological solutions in the education process. Increasingly, many pedagogical ideas and theories are starting to signal the need to transpose the role of the teacher in the spectrum of expert-conceptual practitioner, which is based on the methods and techniques of learning, i.e. critical thinking.

In modern education, a personal attitude towards a teacher defines their mission in education. Equally important is an understanding of one’s subjectivity as a human being and the importance of others in life-long learning, more widely perceived as the growth of humanity. The role of teachers and their educational mission are faced with a number of dynamic dysfunctions, which effectively challenge their ability of achieving teaching career goals, especially through the prism of leadership within education.
