Implementation of histopathological techniques and transmission electron microscopy for research of Mycoplasma hyopneumoniae in swine

Abstract— Mycoplasma hyopneumoniae is a fastidious bacterium, an important member of swine respiratory disease complex, like Porcine Enzootic Pneumonia, affecting the non-specific defense mechanism of the respiratory tract, high mucociliary system, predisposing the pigs to secondary pathogens. The objective of this study is to implement precise diagnostic techniques for identification of Mycoplasma hyopneumoniae. 19 swine lungs fragments were collected from slaughterhouses and submitted by histopathological techniques. The presence of mucocellular exudate in 78.94% of the samples was observed in the bronchi and bronchioles, absence of eyelashes in 63.15% and lymphoid tissue hyperplasia associated with the bronchus in 42.10%. In pulmonary parenchyma, thickening of alveolar wall and interstitial bronchopneumonia were observed in 68.42%, hemorrhage in 47.36%, which 36.84% had hemosiderin and 15.78% lung consolidation. The presence of mycoplasma by the negative staining technique was identified in all samples, also the labeling of epitopes by colloidal gold immunostaining, using monoclonal antibody. In immunohistochemistry techniques and in situ hybridization, the labeled epitope and genome were observed confirming the presence of Mycoplasma hyopneumoniae in the State of São Paulo. Therefore, the bronchial epithelium is the best tissue to collect the sample for an accurate diagnosis and the best method of diagnosis is the negative staining technique for screening and colloidal gold immunocytochemistry techniques to identify Mycoplasma species.

Quantifying the relative impact of physical and human factors on the viticultural expression of terroir

Abstract— This work assesses the relative importance of the terroirs factors: climate, soil and the relation source-sink, on the vegetative development, yield, berry composition and plant sanitary status.

The study was carried out between 2011 and 2014 in nine vineyards from six viticultural regions over the coast of Río de la Plata (Uruguay). The cultivar studied was Tannat, vertically trellised and north-south oriented. The year effect refers to climate, which was characterized using solar irradiation and three indices. The soil was characterized using pits and physico-chemical analyses, to determine three textural categories and to define soil depth and water availability. The source-sink relationship referred to four categories of relations between leaf surface and yield per vine. Statistical analyses included a Mixed Model with random effects to determine the relative importance of each factor to the total variability within the dataset.

Total yield per vine was explained by the source-sink relationship, the year and their interaction, both linked to the rainfall amount occurred during the maturation period. The synthesis of primary compounds in the berries was more dependent on the year and the interaction of soil and year with the source-sink relationship. Secondary compound concentrations in the berry depended mainly on the source-sink relationship and climate.

This study represents a significant advance to the knowledge of grapevine adaptation to the Río de la Plata terroirs, assigning a fundamental role to the vine grower actions. The growers can modulate grapevine balance as a function of the environment.

Keywords berry composition, soil, Tannat, terroir, yield.

Land use and water quality in two sub-basins

Abstract The study evaluated the effects of land use and occupation in water quality in two sub-basins located in the State of Paraná, Brazil. The first sub-basin has 69.8% of native vegetation (natural) and the other has 54.1% of the land cultivated (anthropic). Samples were collected from April to December 2015, analyzing the following parameters: dissolved oxygen, temperature, electrical conductivity, pH, total dissolved solids, turbidity, color, biochemical oxygen demand, total nitrogen, total phosphorus and fecal coliforms. The natural sub-basin presented, significantly, better water quality. Total phosphorus, biochemical oxygen demand and fecal coliforms exceeded the legal limits on the anthropic sub-basin. At this sub-basin correlation was found between cumulative rainfall of five days with turbidity and fecal coliforms, two days cumulative rainfall and total nitrogen, as well as between air and water temperature, affecting the dissolved oxygen, pH, electrical conductivity and fecal coliforms. In the natural sub-basin correlation was found between cumulative rainfall of two days and turbidity, total dissolved solids and electrical conductivity.

Effects of heavy metals' toxicity on plants and enhancement of plant defense mechanisms of Si-mediation “Review"

Abstract Today’s [e.g., “heavy metals (HMs)”] caused by anthropogenic activities have negative impacts on our environment and food productions. HMs can be classified as either essential or nonessential. A trace of essential HMs, such as Cu, Mo, and Zn, can be necessary for plant metabolism, but excess of them can harm the plant growth and development. Nonessential HMs, however, are toxic for plant metabolism and have damaging effects on enzyme activity, photosynthetic properties, cell membrane, permeability and eventually plant growth. Plants with avoidance and tolerance against stress could manage extreme HM stress in soils so that with special mechanisms, such as specific translation and metal accumulation, can elevate abiotic and biotic stress in plants. Moreover, in cells with mechanisms such as [e.g., “Metallothionein (MTs)”] (metal binding proteins) or [e.g., “Phytochelatin (PCs)”] storage and crystallization could reduce the HM stress in the cell wall, plasma membrane, cytosol, tonoplast and vacuoles. Meanwhile, the role of Si-mediation in detoxification of HMs is so bold. Si-mediation with increasing antioxidant, reducing lipid peroxidation, and increasing efficiency of photosynthetic properties elevates the HMs and other biotic and abiotic stresses in plants.

Keywords HMs, stress, cells defense mechanism, Silicon.

The Influence of Soil Organic Matter on the Uptake of Silver Nanoparticles in a Terrestrial System

Abstract The uptake of silver from silver nanoparticles in soil was investigated in the presence of increasing concentrations of soil organic matter. Especially, the effect of Humus component of soil organic matter on the uptake of Ag from silver nanoparticles was studied. Two insect species, Acheta domesticus and Tenebrio molitor, and two plant species, Helianthus annuus and Sorghum vulgare, were exposed to silver nanoparticles(25 ppm in the presence of increasing concentrations of Humus (0, 1, 5, 10, 15, and 20% Humus) in soil (by weight). The techniques of transmission electron microscopy, dynamic light scattering, and powder X-ray diffraction were used to characterize the silver nanoparticles used in the study. An inductively coupled plasma-optical emission spectrometer was used to measure the levels of silver in test samples. Increasing concentrations of Humus in soil has resulted in an increase in the sulfur content and cation exchange capacity of the soil. A general decrease in the concentrations of silver was observed in Acheta domesticus and both the plant species, as a function of increasing concentrations of Humus in soil. In the case of plant species, the accumulation of silver nanoparticles was predominantly observed in the root tissue. Additionally, the translocation of silver from the roots to other plant tissues was observed in the case of Helianthus annuus. Results from this study suggest that the presence of Humus in soil could possibly decrease the uptake of silver from silver nanoparticles by insect and plant species.

Keywords Silver nanoparticles, Acheta domesticus, Tenebrio molitor, Helianthus annus, Sorghum vulgare, inductively coupled plasma-optical emission spectrometer, Soil organic matter, Humus.
