Any process that modulates the frequency, rate or extent of the process of gaseous exchange between an organism and its environment.

The process in which a symbiont organism effects a change in the structure or function of its host cell nucleus.

The process in which an organism effects a change in the structure or function of a host cellular component. The host is defined as the larger of the organisms involved in a symbiotic interaction.

The process in which a symbiont organism effects a change in the structure or function of its host intercellular junction, a specialized region of connection between two cells.

The process in which a symbiont organism modulates the anion transport, the directed movement of anions, atoms or small molecules with a net negative charge, into, out of or within a cell, or between cells, of its host organism.

OBSOLETE. The alteration by a symbiont organism of the functioning of excretion, the elimination by the host organism of the waste products that arise as a result of metabolic activity.

Any process that modulates the frequency, rate, or extent of excretion, the elimination by an organism of the waste products that arise as a result of metabolic activity.

Any process that modulates the frequency, rate or extent of the controlled release of a substance from a cell or a tissue.

The alteration by a symbiont organism of the functioning of a host neurophysiological process, an organ system process carried out by any of the organs or tissues of neurological system.

The alteration by a symbiont organism of the functioning of a respiratory system process, an organ system process carried out by any of the organs or tissues of the respiratory system.

The controlled release of DNA by a cell, via the type IV secretion system.

A highly specialized structure unique to microsporidia that is required for host cell invasion. In the spore, the polar tube is connected at the anterior end, and then coils around the sporoplasm. Upon appropriate environmental stimulation, the polar tube rapidly discharges out of the spore, pierces a cell membrane and serves as a conduit for sporoplasm passage into the new host cell.

A cellular process that results in the biosynthesis of constituent macromolecules, assembly, and arrangement of constituent parts of a membrane.

A process that results in the biosynthesis of constituent macromolecules, assembly, and arrangement of constituent parts of a cellular component. Includes biosynthesis of constituent macromolecules, and those macromolecular modifications that are involved in synthesis or assembly of the cellular component.

Any process that modulates the frequency, rate or extent of a molecular function, an elemental biological activity occurring at the molecular level, such as catalysis or binding.

Any constituent part of the living contents of a host cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm. The host is defined as the larger of the organisms involved in a symbiotic interaction.

That part of a host cell's nuclear content other than the chromosomes or the nucleolus. The host is the larger of the organisms involved in a symbiotic interaction.

A short filamentous structure on the surface of a bacterial cell distinguished from other pili by post-translational N-methylation of the pilin monomers.

A proteinaceous hair-like appendage on the surface of bacteria ranging from 2-8 nm in diameter.

The controlled release of a substance by a cell.
