Background: Medicinal plants have been used for treatments of various health ailments and the practices as a remedial back to thousands of years. Currently, plant-derived compounds used as alternative ways of treatment for multidrug-resistant pathogens. Objective: In the present study, various parts of six medical plants such as Solanum nigrum, Azadirachta indica, Vitex negundo, Mentha arvensis, Gloriosa superba, and Ocimum sanctum were extracted for obtaining biological active constituents. Methods: Soxhlet method of extraction was used for obtaining crude extracts. Agar disc diffusion and 96-well plate spectroscopic reading were used to detect the extract’s antibacterial and antibiofilm properties. Results: The obtained extracts were tested for antimicrobial and antibiofilm properties at 25 mg/mL concentrations. Maximum antibacterial activity was observed in O. sanctum chloroform extract (TUCE) against Staphylococcus aureus (24.33±1.52 mm), S. nigrum acetone extract (MAAC) against Salmonella Typhimurium (12.6 ± 1.5 mm) and Pseudomonas aeruginosa (15.0 ±2.0 mm). Only TUCE exhibited antibacterial activity at least a minimum inhibitory concentration of 0.781 mg/mL. Better antibiofilm activities were also exhibited by petroleum extracts of G. superba (KAPE) and S. nigrum (MAPE) against Escherichia coli, S. Typhimurium, P. aeruginosa and S. aureus. Moreover, S. nigrum acetone extract (MAAC) and O. sanctum chloroform extract (TUCE) were showed anti-swarming activity with a reduction of motility 56.3% against P. aeruginosa and 37.2% against S. aureus. MAAC also inhibits Las A activity (63.3% reduction) in P. aeruginosa. Conclusion: Extracts of TUCE, MAAC, MAPE, and KAPE were exhibited antibacterial and antibiofilm properties against the Gram-positive and Gram-negative pathogenic bacteria. GCMS identified chemical constituents are responsible for being biologically active.

The scientific study of this research has been focused on synergistic antibacterial activity of two weed plants, Lantana camara L., Parthenium hysterophorus L. alongwith two medicinal plants, Cannabis sativa L., Justicia adhatoda L. against multi- drug resistant (MDR) bacteria. Dried leaf powders of the plants were extracted using air-dried method followed by the ethanol- solvent extraction method for the crude extract of the leaves. The crude extracts were tested for antibacterial activity against three MDR bacteria, that is, one Gram positive bacteria- Staphylococcus aureus and two Gram negative bacteria- Escherichia coli and Proteus mirabilis. Out of 18 antibiotics tested against procured bacteria, Staphylococcus aureus was resistant to 10 out of 10 tested antibiotics, Escherichia coli was resistant to 4 out of 12 tested antibiotics and Proteus mirabilis was resistant to 9 out of 10 tested antibiotics. The tested weed plants and the medicinal plants when combined together showed more zone of inhibition against multidrug resistant bacteria ( Two combinations of phytochemicals Lantana camara, Cannabis sativa and Lantana camara, Cannabis sativa, Justicia adhatoda, Parthenium hysterophorus showed maximum zones of inhibition, that is, 30 mm) as compared to when these plants were tested solitarily, showing pronounced antibacterial activity. These findings showed that the antibacterial activity enhanced when they were combined together and this potential could be used against various infectious diseases with more research and modification in this area. Weed plants also holds as much importance as the medicinal plants although not to that extent, but they clearly inhibit the growth of bacteria and this property of weeds along with the medicinal plants holds a promising future in treating many diseases caused by multi-drug resistant bacteria on the pharmaceutical level.

Landscape Ecological Structure in the Eastern Part of the North Vidzeme Biosphere Reserve, Latvia Latvia is a country where the forest area has increased and habitat fragmentation has reversed compared with many other European countries. In order to examine the effect of this expansion on biodiversity, vegetation maps dating from 2002 and the years 1930-1936 were used for comparative landscape structure analyses while archive materials from forest plans, and data from the national forest management database were used for land use analysis. Four landscape ecoregions in the eastern side of the North Vidzeme Biosphere Reserve were selected for analysis. Landscape structure indicators derived from landscape ecology were used for the ecological assessment of land use changes. The total number of forest patches had decreased over the study period, but mean patch size had increased for all types of landscape element. This general change was found to vary between different landscape units in the study area. The biggest change in the area of forest patches occurred in the Rūjiena drumlin field, where the amount of forest patches decreased least and forest area increased the most. This study showed that the internal structure of the forest matrix changed substantially. This finding has implications for biodiversity protection if this trend of land use change continues.

Medicinal plants are the source of biologically active compounds that are in constant demand for the pharmacological industry. Active production of plant secondary metabolites is possible only under optimal conditions of plant growth and development. The state of medicinal plants is controlled not only by genotype and environmental conditions but by the qualitative and quantitative composition of their microbiota as well. The study of the structure and function of the rhizospheric communities of medicinal plants is important for obtaining of high quality medicinal raw materials. Microorganisms are the constant companions of higher plants, which can be used as a medicinal raw material. The rhizosphere microbiota is highly specific, even between different varieties of the same plant species. Each plant species has a specific microbiome of the rhizosphere, depending on the existing soil community. The rhizosphere of medicinal plants is marked by a special highly specific microbiome due to the specificity of root exudates.  Active cell secretion of the roots provides nutrient substrates with microorganisms that form strong associations both inside the root tissues and on the root surface as well as in the soil around the roots. The purpose of the research was to study the effect of medicinal plants of different systematic groups on the composition of the microbial communities of the rhizosphere. The experiments were conducted in 2018–2019 at the nursery medicinal plant plot of the Department of ecology and botany of Sumy National Agrarian University. Ecological-trophic groups of microorganisms associated with the roots of medicinal plants in the experiment were represented by ammonifying bacteria, nitrogen-fixing bacteria and bacterias that destroyed of plant residues (cellulose-destroying bacteria). In the analysis of the total number of microorganisms of the rhizosphere revealed differences in the quantitative and qualitative composition of microbiota, due to the specific features of a medicinal plant. Positive influence on the development of microflora in the area of the roots and individual ecological-trophic groups had Mentha longifolia (L)., and a negative effect was observed in plants of Bergenia crassifolia L. It has been established that the number of microorganisms and the diversity of ecological-trophic groups is due to the belonging of a medicinal plant to a particular taxon. The number of microorganisms and their diversity decreased in the direction of: Mentha longifolia – Lysimachia vulgaris – Aristolochia clematitis – Achillea submillefolium – Bergenia crassifolia.
