OBSOLETE. Any process that stops, prevents, or reduces the frequency, rate or extent of the increase in size or mass of an organism occurring in, on or near the exterior of its host organism.

Any process that stops, prevents, or reduces the frequency, rate or extent of the progression of an organism from an initial condition to a later condition, occurring in, on or near the exterior of its host organism.

OBSOLETE. Any process that activates or increases the frequency, rate or extent of the increase in size or mass of an organism occurring in, on or near the exterior of its host organism.

Any process that activates or increases the frequency, rate or extent of the progression of an organism from an initial condition to a later condition, occurring in, on or near the exterior of its host organism.

OBSOLETE. Any process that stops, prevents, or reduces the frequency, rate or extent of the increase in the symbiont's size or mass on or near the cells or tissues of the host organism.

The lipid bilayer surrounding a host cell endosome.

Thin, stiff protrusion extended by the leading edge of a motile host cell such as a crawling fibroblast or amoeba, or an axonal growth cone; usually approximately 0.1 um wide, 5-10 um long, can be up to 50 um long in axon growth cones; contains a loose bundle of about 20 actin filaments oriented with their plus ends pointing outward.

A compound membranous cytoplasmic organelle of eukaryotic host cells, consisting of flattened, ribosome-free vesicles arranged in a more or less regular stack.

The lipid bilayer surrounding any of the compartments of the host cell Golgi apparatus.

The cytolytic destruction of red blood cells, with the release of intracellular hemoglobin, in one organism by another.

The killing by an organism of a cell in another organism by means of the rupture of cell membranes and the loss of cytoplasm.

The irregular network of unit membranes, visible only by electron microscopy, that occurs in the host cell cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The host smooth ER has no ribosomes adhering to the outer surface.

The irregular network of unit membranes, visible only by electron microscopy, that occurs in the host cell cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The host ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached).

The lipid bilayer surrounding the host cell smooth endoplasmic reticulum.

The lipid bilayer surrounding the host cell endoplasmic reticulum.

A complex system of membrane-bounded compartments located between host cell endoplasmic reticulum (ER) and the host Golgi complex, with a distinctive membrane protein composition; involved in ER-to-Golgi transport.

Organized structure of distinctive morphology and function, as found in host cells, bounded by a single or double lipid bilayer membrane and occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane. The host is defined as the larger of the organisms involved in a symbiotic interaction.

The lipid bilayer surrounding any of the compartments of the host cell ER-Golgi intermediate compartment system.

A membrane-bounded organelle that carries materials newly ingested by endocytosis. It passes many of the materials to host cell lysosomes for degradation.
