Opis:
Sewage sludge is a by-product in the wastewater treatment and is an inherent hazardous issue because of the pathogenic contamination of natural resources. Therefore, in this study, domestic sludge was treated with premontane forest soil, macronutrients, and also pasteurization to reduce the content of volatile solids and pathogens. The best biostabilization treatment using premontane forest soil and pasteurization obtained a volatile solids reduction of 87% according to the environmental regulations, in which a biosolid is stable in a range of 38% of volatile solids reduction. In less than 30 days in a mesophilic range, the coliform count was reduced up to 71% when using forest soil and pasteurization. Thus, a biosolid-class B was obtained using gravimetric means as a platform to promote fast quality control.

Opis:
Seeds of ten cultivars of spring wheat from five different localized breeding stations were tested for seedhealth. The same seeds were sown in Radzików in field experiment and its seed health after harvest was evaluatedalso. The basic material of wheat was infected by numerous fungi: 36 fungal species belonging to 24genera and the most often occurred: Alternaria alternata, Epicoccum purpurascens, Fusarium spp.,Drechslera spp. and B. sorokiniana. It was found significant differences between cultivars for total fungioccurred on seeds, for seed infection by main pathogens (B. sorokiniana, Drechslera spp. and Fusariumspp.). Also seeds from breeders were strongly infected by these pathogens in comparison to seeds harvested infield experiment in Radzików.

The antagonistic activity of some Biological Control Agents (BCA) isolates of Trichoderma sp., Penicillium sp., Gliocladium sp., and Actinomycetes - Streptomyces sp. against pathogens of sugar beet damping-off: Aphanomyces cochlioides, Pythium debaryanum and Phoma betae was tested in vivo and in vitro. Fourty-nine isolates of fungi and seventy four of Actinomycetes were isolated from compost and soil in which those pathogens did not occur. The microorganisms effective against at least two pathogens in vitro tests were incorporated into the soil or added to the seed as a treatment during pelleting process. The microorganisms used in vivo tests limited the number of infected seedlings. Some of them protected emerging plants on the same level as fungicides commercially used for seed treatment.

Opis:
The purpose of that article was to show the significance of water as the source of plant pathogens, and need of it effective disinfection methods in modern agriculture and horticulture. The increase in the cost of agricultural water use for crop irrigation and the necessity of using the same water several times, as well as the changing climatic conditions, including prolonged shortage of atmospheric precipitation and often extreme temperatures during the summer, necessitate the selection of an effective, easy to apply and economical method of disinfecting recirculated water to eliminate or minimize the occurrence of the most serious plant pathogens inhabiting various water sources. Among them, microorganisms of the genera Phytophthora, Pythium and Fusarium, and the species Rhizoctonia solani, Verticillium dahliae and some pathogenic bacteria pose the most serious threat. Some of them can be found in rivers, streams, ponds and water reservoirs, others are soil-borne pathogens that cause root and stem base rot of many plant species. The available literature describes at least a dozen methods of water disinfection, among them slow filtration through sand or lava filters, chlorination and heating. The literature data indicates that the use of sand filters is the most effective, safe and cheapest method of water disinfection.

Opis:
Plant secondary metabolites have a variety of functions, including mediating relationships between organisms, responding to environmental challenges, and protecting plants against infections, pests, and herbivores. In a similar way, through controlling plant metabolism, plant microbiomes take part in many of the aforementioned processes indirectly or directly. Researchers have discovered that plants may affect their microbiome by secreting a variety of metabolites, and that the microbiome could likewise affect the metabolome of the host plant. Pesticides are agrochemicals that are employed to safeguard humans and plants from numerous illnesses in urban green zones, public health initiatives, and agricultural fields. The careless use of chemical pesticides is destroying our ecology. As a result, it is necessary to investigate environmentally benign alternatives to pathogen management, such as plant-based metabolites. According to literature, plant metabolites have been shown to have the ability to battle plant pathogens. Phenolics, flavonoids, and alkaloids are a few of the secondary metabolites of plants that have been covered in this study.

Opis:
Natural killer (NK) cells play a major role in the initial control of many viral pathogens and in the rejection of tumors. Consistent with their roles as immune sentinels, NK cells are found in inflamed skin, including lichen planus, psoriasis and atopic dermatitis (AD) lesions. In oral lichen planus lesions, the recruitment as well as intradermal colocalization of NK cells and pDC (plasmacytoid dendritic cells) appear to be mediated by chemerin, a recently identified protein ligand for chemokine-like receptor 1 (CMKLR1), a chemoattractant receptor expressed by both cell types. Dendritic cells can regulate NK cell activity, and NK cells can regulate DC-mediated responses. Since chemerin was recently implicated in recruitment of pDC to psoriatic skin, in this work we determined whether chemerin facilitates interactions between NK and pDC in psoriatic plaques through controlling influx of NK cells to diseased skin. We demonstrate that circulating NK cells from normal donors as well as psoriasis and AD patients respond similarly in functional migration assays to chemerin. However, differences in the distribution of NK cells and pDC in skin lesions suggest that recruitment of both NK cells and pDC is unlikely to be controlled solely by chemerin.

Opis:
Objectives: The study presents data concerning occupational exposures among the staff of 5 hospitals in the Małopolska province in 2008–2012, taking into account the frequency and circumstances of exposure formation, occupational groups of hospital workers, as well as diversification of the reported rates in subsequent years between the hospitals and in each of them. An additional objective of the analysis was to assess the practical usefulness of the reported data for planning and evaluation of the effectiveness of procedures serving to minimize the risk of healthcare workers’ exposure to pathogens transmitted through blood. Material and Methods: Data were derived from occupational exposure registries kept by 5 hospitals of varying sizes and operational profiles from the Małopolska province from the years 2008–2012. Results: Seven hundred and seventy-five cases of exposure were found in a group of 3165 potentially exposed workers in the analyzed period. Most cases were observed in nurses (68%) and these were mainly various types of needlestick injuries (78%). Exposure rates with respect to all workers ranged from 2.6% to 8.3% in individual hospitals, but the differences in their values registered in the hospitals in subsequent years did not bear any statistical significance, in a way similar to the rates calculated separately for each occupational group. Conclusions: There was no upward or downward trend in the number of reported cases of exposure to bloodborne pathogens in the studied period in any of the hospitals. Statistically significant differences in the percentages of exposures were reported between individual hospitals in some years of the analyzed period, which confirms the need for registries in individual units in order to plan and evaluate the effectiveness of preventative measures.

Opis:
W 1994 r. Instytut Ochrony Roślin otrzymał dotację Ministerstwa Rolnictwa na zorganizowanie Kolekcji Patogenów Roślin. Celem projektu było utworzenie centralnej polskiej kolekcji grzybów, bakterii i wirusów chorobotwórczych charakterystycznych dla roślin rolniczych, gleb i klimatu w Polsce. Do 1996 r. zaadaptowano dwa pomieszczenia: pomieszczenie danych podstawowych oraz pomieszczenie identyfikacji i dostępu. Zamówiono aparaturę naukową, środki chemiczne, meble i książki. W ciągu dwóch kolejnych lat wyremontowano i wyposażono pozostałe pomieszczenia. Każdy patogen zachowywano dwiema uzupełniającymi się metodami, głównie przez liofilizację i zamrażanie w ciekłym azocie. Do 2016 roku zebrano 1748 kultur grzybów chorobotwórczych i 192 szczepy bakterii.
In 1994 The Institute of Plant Protection received the subsidy of Ministry of Agriculture to organize the Collection of plant pathogens. The aim of the project was to settle the central Polish collection of fungi, bacteria and viruses pathogenic and characteristic to agricultural plants, soils and climate in Poland. Up to 1996 two rooms were adapted: the room of the basic data and the identification and access room. Scientific equipment, chemicals, furniture and books have been ordered. In the period of two following years the rest of the rooms were renovated and equipped. Each pathogen have been conserved by means of two complementary methods, mainly by the freeze-drying and freezing in the liquid nitrogen. Till 2016, 1748 cultures of pathogenic fungi and 192 strains of bacteria have been collected.
