The method of the invention is a solution that allows the simultaneous isolation of microbial DNA from the blood. In this method the isolation is carried out by compilation of enzymatic, mechanical and thermal lysis. This approach enables to obtain DNA from all types of organisms, irrespective of the structure of the cells.The obtained precipitate is subjected to further preparations, using a commercial DNA isolation kit according to the protocol provided by the manufacturer's procedure. The procedure results in obtaining the DNA ready for further stages of the analysis, e.g. performing a PCR reaction to detect fungi. The most important and most difficult problem in the treatment of bloodstream infections, determining the effectiveness of therapy and, consequently, the cost and time of hospitalization, is the effective diagnosis of factors responsible for the systemic inflammatory response in the course of sepsis. Determination of etiologic factors allows for selection of appropriate antibiotic therapy. The material subjected to diagnostic testing is blood taken from the patient showing clinical signs of sepsis. Currently, the "gold standard" diagnostic method is testing for microbial growth after inoculation in culture media specific to selected pathogen groups. This method is relatively simple and inexpensive, but also time-consuming – results can be available as late as in 5 days. Moreover, identification of pathogens with this method often fails due to low sensitivity; microbial growth can be detected in only about 15-20% of the cultures.

Mesenchymal Stem Cells (MSCs) are multipotent precursor cells with the unique capacity to self-renew, proliferation and transformation into specialized cells present in many body tissues, such as muscle, adipose tissue, fibroblasts, cartilage, tendons, and nervous tissue. They are also characterized by the ability to affect the immune system by secretion of compounds that support the immune response directed among others against bacteria and parasites. They have properties enabling the secretion of chemical compounds that stimulate the formation of new blood vessels. All these attributes make them applicable in regenerative medicine, transplantology and in the treatment of many diseases. The umbilical cord blood and Wharton’s jelly MSCs are the sources from which MSCs are obtained. Due to the small amount of MSCs in the starting material, it is necessary to lead in vitro cultures to obtain sufficient numbers of cells that can be administered to the patient. Methods of isolation and culture of mesenchymal stem cells, including the growth medium, play a crucial role in obtaining the appropriate biological material that guarantees therapeutic success. Therefore, continuous improvement of procedures for isolating and in vitro culturing of MSCs is extremely important. The subject of the offer is a method of culturing mesenchymal stem cells using secretions from carnivorous plants, which increase cell adherence and proliferation, counteract their transformation into specialized cells, therefore, they longer maintain their pluripotency.
