obsolete regulation of growth of symbiont in host (obsolete GO:0044126)
OBSOLETE. Any process in which the symbiont regulates the increase in its size or mass 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. The host is defined as the larger of the organisms involved in the symbiotic interaction.
