“…This pathogen initially infects the exocuticle and after the endocuticle; in more susceptible species or individuals, it penetrates the basal lamina, underneath the epidermis cell layer and spreads throughout the body, invading connective tissue and blood vessels (Cerenius et al, 1988). Aphanomyces astaci does not produce sexual structures, with transmission occurring via zoospores released from infected animals and it is able to survive for several days in water and several weeks in mud (Alderman and Polglase, 1988;Diéguez-Uribeondo et al, 1995;Edgerton et al, 2002). Besides A. astaci, another parasitic fungus that can infests P. clarkii carapace and constitute a threat to other crustaceans is Saprolegnia parasitica (Diéguez-Uribeondo et al, 1994).…”

-Alien species have been transported and traded by humans for many centuries. However, with the era of globalization, biological invasions have reached notable magnitudes. Currently, introduction of alien species is one of the major threats to biodiversity and ecosystem functioning. The North American crayfish Procambarus clarkii is one of the most widely introduced freshwater species in the world, especially due to its high economic importance. It is responsible for great modifications in invaded environments causing irreparable ecological and economic damages. Its impressive ability to successfully colonize a wide range of environments is a consequence of its behavioural and biological characteristics that can adapt to features of the invaded location, conferring to this species a notable ecological plasticity. This review summarizes the available information regarding P. clarkii's biology and invasive dynamics around the world in order to contribute to the understanding of the threats posed by its establishment, as well as to support management and impact mitigation efforts.

“…leniusculus, in the early 1970's constituted the way by which the fungus, A. astaci, was introduced into the Iberian Peninsula (DIEGUEZ-URIBEONDO ef a/., 1997b). This is because all populations of North American crayfish studied in Spain have'been found to be infected with the crayfish plague fungus and because they carry specific strains from their natural habitat in North America (DIEGUEZ-URIBEONDO et al, 1995 ;DIEGUEZ-URIBEONDO andTEMINO, 1998, DIEGUEZ-URIBEONDO andSODERHALL, 2000). Since the crayfish plague fungus is an obligate parasite, which can only survive in freshwater crayfish species (CERENIUS and SODERHALL, 1992), these introductions have resulted in the establishment of chronic infected areas in the waters of Spain.…”

“…The crayfish plague is the most serious disease affecting freshwater crayfish and it has cc wiped out ,, many populations of native crayfish in Europe. This disease is caused by the oomycetous fungus Aphanomyces astaci (UNESTAML~ 969), which is endemic to North America (UNESTAM, 1972 ;HUANG et a/., 1994 ;DIEGUEZ-URIBEONDO, 1995) and was probably introduced into Europe around 1860 (AL~ERMAN and POLGLASE, 1988). It is known that at least three different strains of this fungus have been introduced into Europe during the last three decades by the stocking with North American crayfish, i.e.…”

“…The purpose of this work was to characterise the activation of the proPO system in the red swamp crayfish, Procambarus clarkii, as this system has been reported to be important in the innate immunity of crustaceans. Procambarus clarkii is a commercially important species and can su#er mass mortalities due to bacterial or other pathogenic infections (Thune et al, 1991;Diéguez-Uribeondo et al, 1995). Methods to determine the onset of disease are at present unknown, and it is possible that understanding the activation of the proPO system in the animals could lead to the development of diagnostic tools to assess animal health, or treatments to augment natural defence systems.…”

The prophenoloxidase (proPO) system is considered an important mechanism of innate defence in arthropods. This enzymatic cascade has been studied in crustaceans such as the crayfishes Astacus astacus and Pacifastacus leniusculus and is located inside the haemocytes. An initial characterisation of this system in the commercially important red swamp crayfish Procambarus clarkii is described. The P. clarkii proPO system was activated by trypsin and also by zymosan A. This activation was calcium ion dependent. The calcium ion concentration also a#ected the background activation of the system and at 5 mM was highest as measured by the ability of phenoloxidase to oxidise L-3,4-dihydroxyphenylalanine. The e#ect of calcium ions appears to be related to the activation of an endogenous serine protease, but other calcium ion-dependent factors can also a#ect proPO activation. Lipopolysaccharides (LPS), glycolipids found in the outer leaflet of the outer membrane of Gram-negative bacteria, were also able to activate the proPO system in P. clarkii after a significant lag time of 25 to 30 min. However, LPS derivatives (deacylated LPS, lipid A and -D-GlcNAc-[1<6]-D-GlcNAc) were not able to activate the enzymatic cascade in P. clarkii. Activation of the proPO system in other crayfishes by LPS has been shown to be mediated by serine protease-like enzymes. The observed e#ect of LPS and LPS derivatives on the activation of the P. clarkii proPO system suggests that a protease activity triggered by these molecules may be mediated through the recognition of a ''complete'' LPS molecule (polysaccharide and lipid A). The intermolecular recognition of LPS by a putative endogenous serine protease zymogen might explain the lag time observed in proPO activation. Academic Press Limited
