The set of specific processes that generate the ability of an organism to induce an abnormal, generally detrimental state in another organism.

Any process that stops, prevents, or reduces the frequency, rate or extent of blood coagulation.

A process that solubilizes fibrin in the bloodstream of a multicellular organism, chiefly by the proteolytic action of plasmin.

A series of reactions that takes place outside the cell occurring in response to tissue damage and initiated within blood plasma by the action of activated Factor XII (Hageman Factor) on prekallikrein to convert it to plasma kallikrein, and the subsequent reaction of plasma kallikrein with high molecular weight kininogen. The ultimate product of the plasma kallikrein-kinin cascade is bradykinin, an agent known to induce smooth muscle contraction, vasoconstriction, and increased vascular permeability.

Any process that activates or increases the frequency, rate or extent of blood coagulation.

A process that begins with venom being forced into an organism by the bite or sting of another organism, and ends with the resultant activation, maintenance or an increase in the frequency, rate or extent of platelet aggregation in the bitten organism.

A process that begins with venom being forced into an organism by the bite or sting of another organism, and ends with the resultant hydrolysis of proteins in of the bitten organism.

The process which begins with venom being forced into an organism by the bite or sting of another organism, and ends with fibrinogenolysis, a process that degrades fibrinogen at a variety of Arg-Lys bonds, thus impairing fibrinogen clotting in the bloodstream of the bitten/stung organism.

The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
