“…the content of microelements, and implicitly the contaminants from the studied plants show some inadequate values that were obtained with Cd: 90.44 ± 2.72 μg/kg ( Althaea officinalis ). In this case, the Cd concentration exceeds the maximum admissible limits [ 32 , 33 ]. Other slightly toxic elements (Pb, Ni, Cr) can be found in small quantities in all analyzed plants.…”

“…Based on these plants and others of which a antimicrobial effect was observed in previous published research [ 27 , 33 , 60 ], eight recipes of plant derived products have been established. Minimum inhibitory and bactericidal concentrations for plant extract were detected in order to choose the plants feasible for obtaining final products with a possible intramammary application.…”

“…The mineralization of the samples was performed in a microwave furnace, Berghof digestion system MWS-2. Approximately 0.3 g of the homogenized plant samples were placed in special Teflon tubes, 2 mL of 65% HNO 3 was added and let to react for 15 min, after which 3 mL of H 2 O 2 was added before the container was sealed [ 33 , 67 , 68 , 69 ].…”

“…The reagents used to perform the analyses were of analytical purity, namely 65% nitric acid and ultra-purified water. For the calibration curve, following dilutions of standard solutions were used: chromium (10 μg/L), manganese (10 μg/L), calcium (2 μg/L), nickel (50 μg/L), iron (20 μg/L), cadmium (2.0 μg/L), sodium (4.0 μg/L), potassium (5.0 μg/L), zinc (2.0 μg/L), selenium (100 μg/L), magnesium (1.0 μg/L), copper (25 μg/L), and lead (50 μg/L) [ 33 , 68 ].…”

Bovine mastitis a major disease that is commonly associated with bacterial infection. The common treatment is with antibiotics administered intramammary into infected quarters of the udder. The excessive use of antibiotics leads to multidrug resistance and associated risks for human health. In this context, the search for alternative drugs based on plants has become a priority in livestock medicine. These products have a low manufacturing cost and no reports of antimicrobial resistance to these have been documented. In this context, the main objective of this study was to determine the antimicrobial effect of extracts and products of several indigenous, or acclimatized plants on pathogens isolated from bovine mastitis. A total of eleven plant alcoholic extracts and eight plant-derived products were tested against 32 microorganisms isolated from milk. The obtained results have shown an inhibition of bacterial growth for all tested plants, with better results for Evernia prunastri, Artemisia absinthium, and Lavandula angustifolia. Moreover, E. prunastri, Populus nigra, and L. angustifolia presented small averages of minimum inhibitory and bactericidal concentrations. Among the plant-derived products, three out of eight have shown a strong anti-microbial effect comparable with the effect of florfenicol and enrofloxacin, and better than individual plant extracts possibly due to synergism. These results suggest an important anti-microbial effect of these products on pathogens isolated from bovine mastitis with a possible applicability in this disease.

This study aimed to characterize raw honeys from different geographical origins in Romania, in respect of chemical composition, microbiological examination and evaluate their probiotic potential. The physico-chemical determinations were performed in APHIS-DIA Laboratory, Cluj-Napoca, Romania, using standard validated methods. Bacterial identification was performed for each sample and each colony type using Vitek® 2 Compact 15 system and PCR amplification using 16S rDNA bacterial universal primers (27F, 1492R), species being confirm by sequences analysis. In five raw honey samples, we have identified probiotic bacteria, such as: Bacillus mycoides, Bacillus thuringiensis, Bacillus amyloliquefaciens, Bacillus subtilis, and Bacillus velezensis. Generally, all honey samples meet the standard values for chemical composition. However, one sample having 7.44% sucrose was found to have also probiotics bacteria from the genus Bacillus because sucrose is a substrate for probiotics development. In conclusion, the Romanian raw honey can be a potential reservoir of probiotics, which confer a health benefit for consumers.
