Opis:
Calf diarrhea continues to be the major problem of calves in the neonatal period. The effect of zeolites has been increasingly studied in ruminant health in recent years. In the present study, the efficacy of cristobalite, a zeolite, in neonatal calf diarrhea was studied first time. For this purpose, twenty-five neonatal calves with diarrheas were divided into two groups, and Group 1 (n=12) received conventional treatment and Group 2 (n=13) received cristobalite (Zoosorb 10 mg/kg) orally 3 times a day in addition to conventional treatment. Escherichia coli k99 and CS31a, bovine rotavirus and bovine coronavirus were isolated from fecal samples at the beginning of the treatment, on the third day and before discharge. It was determined that the recovery period in Group 2 was 0.95 (20.6%) days shorter than in Group 1 (p<0.05) while no viral agents were found on the fifth day in Group 2, viral shedding continued in 4 of 5 calves in Group 1. In conclusion, the study revealed that cristobalite speeds the recovery time and possibly decreases viral shedding in neonatal calf diarrhea, demonstrating a remarkable efficiency in the treatment.

Opis:
Investigating dolomite fragments derived from pre-existing dolomite-containing sediments or rocks, that is detrital dolomites, constitutes a challenge in carbonate sedimentology. Detrital dolomites are generally difficult to recognize and their presence can have profound consequences, even in small quantities, on the interpretation of the tectonosedimentary evolution and palaeoenvironmental conditions of the enclosing basin. In addition, identification and quantification of detrital dolomites may provide insight into provenance and sediment transportation, quality of hydrocarbon reservoirs, and some aspects of the dolomite problem. Typically, detrital dolomites are recognized by their clastic behaviour, such as 1) their wide range of grain sizes and shapes, 2) evidence for transportation and weathering, and 3) their association with other detrital grains. Detrital dolomite can be derived from dolomite-containing sediments (by reworking) or dolomite-containing rocks (by disintegration) and can be transported by various means including wind, water, glaciers and sediment gravity flows. Detrital dolomite can be found in a variety of lithofacies confirming that they are controlled by availability of dolomite detritus and not by depositional environment. The role of detrital dolomite in promoting diagenetic dolomitisation is examined whereby they have provided nucleation sites, for syntaxial overgrowth, or a source of Mg, through dissolution.

Opis:
Microbially assisted phytoremediation is considered as the most promising eco-friendly solution for recultivation of heavy metal polluted soils. In vitro experiments can be favorable systems that allow assessing compatibility and efficiency of both partners (e.g. plant-microorganism) which reduces time and space in the initial stages of this technology. The main objective of this study was: (1) to calculate the Cd2+ accumulation factors (e.g. BCF, Ti, AF) using willow (Salix viminalis L.) inoculated with three Streptomyces sp. strains under in vitro conditions and (2) to compare obtained results with that derived from pot experiments by Złoch et al. (2017). Our results reveal significantly increase in Cd2+ accumulation capacity of Streptomyces spp. inoculated wil- low plants, indicating microbial stimulation of phytoextraction. Additionally, inoculated plants showed higher biomass production and lower lipids peroxidation level. The results revealed significant increase of MEA, BCF, Ti, MER by Strep-1 and Strep-2 in the above-ground parts of inoculated plants. Moreover, of the three strains tested, Strep-1 (Streptomyces sp. SIIB-Zn-R8) demonstrated the highest impact on the Cd2+ phytoextraction efficiency. In conclusion, the proposed in vitro model system allowed predicting Cd2+ phytoextraction capacity per- formed using inoculated willow plants with the significant reduction of both time and space.
