The chemical reactions and pathways resulting in the breakdown of lipids, compounds soluble in an organic solvent but not, or sparingly, in an aqueous solvent.

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

The chemical reactions and pathways resulting in the breakdown of lipids, compounds soluble in an organic solvent but not, or sparingly, in an aqueous solvent.

The increase in size or mass of an organism, occurring within the cells or tissues of the host organism. This may (but not necessarily) include a filamentous growth form, and also can include secretion of proteases and lipases to break down host tissue. The host is defined as the larger of the organisms involved in a symbiotic interaction.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of deprivation of nourishment.

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

The process in which a multicellular organism, a unicellular organism or a group of unicellular organisms grow in a threadlike, filamentous shape.

The process in which a group of unicellular organisms grow in a threadlike, filamentous shape in response to deprivation of nourishment.

The process in which a group of unicellular organisms grow in a threadlike, filamentous shape in response to a biotic (living) stimulus.

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.
