Parasitic castration in Fissurella crassa (Archaeogastropoda) due to an adult Digenea, Proctoeces lintoni (Fellodistomidae)

Abstract: Specimens of Fissurella crassa (Archaeogastropoda) from Ilo, southern Perú, are infected with the adult stage of the digenetic trematode Proctoeces lintoni (Fellodistomidae). The histopatological analysis of the male and female gonads show a strong effect of the parasite on the structure and function of these organs. P. lintoni live unencysted in the gonads, and the main mechanical damage is originated by the action of a well developed acetabulum. Chemical actions of parasitic secretions may also be involved. … Show more

“…In South America, studies of parasites and diseases of bivalves are scarce (CaceresMartinez & Vasquez-Yeomans 2008), even though they are important and necessary. In Chile, major contribution about presence of parasites in molluscs have been recorded by Oliva (1984Oliva ( , 1992, Oliva et al (1986Oliva et al ( , 1999Oliva et al ( , 2010, Franjola & Gallardo (1991), Gallardo et al (1992), Oliva & Vega (1994), García-Tello et al (2002), Valderrama et al (2004), and pathogens by Lohrmann et al (2002), Lohrmann (2009), Campalans & Lohrmann (2009. However, the knowledge of pathogens and parasites in marine organisms inhabiting San Jorge Bay (Antofagasta) and the majority of the Chilean coast remains largely unknown.…”

“…Sporocysts of this trematode occur within reproductive tissues, where they cause parasitic castration, a condition defined as a total or partial reduction in gamete production (Sullivan et al 1985, Emerson-Kagoo & Ayyakkannu 1994. While this phenomenon has been observed in several species of bivalves (Feng 1988, Cousteau et al 1990, Jonsson & André 1992, Lasiak 1991, Santos & Coimbra 1995, Calvo-Ugarteburu & McQuaid 1998, Rantanen et al 1998, Silva et al 2002 and gastropods (Reader 1973, Sullivan et al 1985, Oliva 1992, Oliva et al 1999, the extent of the gonadal damage has not been measured at the histological level. Although the bivalve mytilid Perna perna when parasitized by bucephalid trematodes has marked reduction in reproductive tissue (Silva et al 2002), no quantitative information about the damage at the germ cell line level is available.…”

“…Mechanisms responsible for the gonadal changes due to parasitic castration are postulated to be the result of physical (ingestion, abrasion, or sporocyst pressure) or chemical (secretion of lytic substances, toxins, or endocrinological antagonists) effects by parasites in the gonad (Oliva 1992). Moreover, clams have an integrated neuroendocrine-nerve ganglion-gonad axis that is susceptible to parasitism, resulting in regulatory changes of the axis (Coustau et al 1991(Coustau et al , 1993, documented in gonads with changes in the kinetics of the gametogenesis.…”

“…Parasites of other marine gastropods from this zone are also only infected by 1 parasitic species; this has been found to be the case in 5 species of key-hole limpets Fissurella spp. (Oliva & Diaz 1988, 1992, suggesting an impoverished pattern of infection similar to those described for marine teleost fishes in central Peru and northern Chile (Oliva et al 1996).…”

“…The only published work (Canas & Lozada 1987) regarding the parasites of C. concholepas includes the record of a n unidentified fellodistomid which can mechanically destroy the digestive gland and the gonads. Mechanical castration by adult fellodistomids has been was described (Oliva 1992) in the marine gastropod Fissurella crassa in northern Chile. We analyze herein quantitative aspects of the process of infection and describe the histopathological alteration in the hepatopancreatic-gonadal complex (HGC) due to sporocysts of Proctoeces sp., a fellodistomid digenean fluke.…”
