                  Human health is currently threatened by diseases that cannot be treated with existing
             drugs. Moreover, they often result from the usage of common drugs and disinfectants. The
             causes  of  outbreaks  of  such  diseases  are  microorganisms  resistant  to  antibiotics  (CRE,  C.
             difficile,  MRSA,  N.  gonorrhoeae,  MDR/XDR  tuberculosis)  or  disinfectants,  including
             disinfectants of drinking water (Cryptosporidium spp, viruses), or disinfectant-resistant toxins
             of  microorganisms  (Shiga  toxin  of  E.  coli  O157:H7  or  O104:H4),  also  viruses,  including
             emerging,  such  as  SARS-CoV-2.  Since  effective  anti-viral  drugs  have  never  been  found.
             Therefore, novel types of antibiotics need, as well as disinfectants. Both enzymes (proteases,
             phosphatases, etc.) and protease inhibitors capable of cleaving / inhibiting vital pathogenic
             proteins  and  nucleic  acids  may  be  useful.  Animal  venoms  are  offered  as  a  source  of  such
             enzymes, potential novel drugs. Bee venom (BV) is one of the best candidates because it is not
             directed against mammals, but against bee enemies, such as arthropods and parasites, as well
             as against bacteria, protozoa, viruses, fungi, from which the bee protects itself by sprinkling its
             venom. Our study aimed to find the BV components responsible for such a broad antimicrobial
             activity of bee venom, for therapeutic purposes and as disinfectants.
                  We divided the bee venom into fractions by chromatography (HPLC) and analyzed the
             fractions of the chromatographic peaks in the polyacrylamide gel to determine the fractions
             containing proteins (enzymes) and their biological activity in human blood, mainly their effect
             on blood clotting and prevention of such coagulation, which is often affected by the infection.
             In addition, we interpreted the found proteins (enzymes) using mass spectrometry.
                  We obtained interesting data on protease as well as a protease inhibitor, which were
             previously found in bee venom, but have not yet been well studied. Our data suggest that both
             BV protease and protease inhibitor may be more potent than many viral, bacterial, or parasitic
             proteases  and  protease  inhibitors,  and  therefore  might  be  used  to  destroy  them  or  their
             activity;  for  example,  to  cleave  (protease)  or  inhibit  (protease  inhibitor)  the  proteases  of
             coronavirus SARS-CoV-2, known to be critical for viral spread. Due to the same ability, they also
             might  be  potent  disinfectants.  In  addition,  we  observed  a  significant  decrease  of  blood
             coagulation  via  inhibition  of  tissue  factor  by  BV  protease  inhibitor.  This  suggests  that  BV
             protease inhibitor can inhibit the extrinsic pathway of blood coagulation, which is known to
             activate as a result of tissue damage along with the release of cytokines leading to thrombosis.
             Such mechanism of thrombosis has also been shown in Covid-19 pathophysiology. We also
             observed that bee venom Phospholipase, already used in human therapy but potentially toxic
             to human cells, is included in a complex with other proteins that might prevent its toxicity.
