Diéguez-Uribeondo et al. (1997) state that, "The signal crayfish Pacifastacus leniusculus (Dana, 1852) is an American species that was introduced into Spanish rivers. This species carries the oomycete A. astaci and can transmit it to the native European crayfish species. Although P. leniusculus is often a carrier of this oomycete, it generally does not suffer from aphanomycosis; however, if individuals are under stressful conditions, such as the presence of another pathogen or parasite, the chronic infection can develop into an acute, fatal condition.
威胁濒危物种: Aphanomyces astaci impacts a threatened species of crayfish in Spain. Dieguez-Uribeondo et al (1997) studied the attempts to re-establish a threatened species of crayfish in Spain, Austropotamobius pallipes see IUCN Red List of Threatened Species. Two introduced species of crayfish are known to carry the water mould or oomycete, Aphanomyces astaci, in their cuticles and to transmit it to Austropotamobius pallipes
