Clinostomum complanatum (Digenea, Clinostomidae) density in Rhamdia quelen (Siluriformes, Pimelodidae) from South Brazil

Abstract

ABSTRACT

Experimental and Molecular Study of Cercariae ofClinostomumsp. (Trematoda: Clinostomidae) fromBiomphalariaspp. (Mollusca: Planorbidae) in Brazil

“…The metacercariae experimentally obtained resemble those identified as C. marginatum and C. complanatum by different authors in Brazil (Thatcher, 1981;Vianna et al, 2003Vianna et al, , 2005. These 2 species have been considered as synonyms for a long time, but morphological and molecular studies revealed that they are distinct species occurring in the New and Old Worlds, respectively (Dzikowski et al, 2004;Caffara et al, 2011;SerenoUribe et al, 2013).…”

“…Although about 50 nominal species have been described (Ukoli, 1966;Vianna et al, 2003) and reported in several species of definitive and second intermediate hosts (fish, amphibians, and reptiles), studies aiming to elucidate the snails (first intermediate host) involved in the life cycles of these trematodes are relatively scarce. Given the potential pathogenic effects of Clinostomum on bird definitive hosts (Shamsi et al, 2013), the frequent reports of accidental human infections (Chung et al, 1995;Kitagawa et al, 2003;Park et al, 2009), and especially the potential damage caused to fish farming (yellow grub diseases) (Lane and Moris, 2000;Bonett et al, 2011), the determination of the first intermediate hosts becomes more important and could contribute to future strategies aimed at controlling these parasites.…”

“…At 60 days postinfection, surviving fish were euthanized by decapitation, the metacercariae were recovered, mechanically excysted with the aid of metal needles, pressed between 2 glass slides and fixed in 10% formalin. Measurements of the developmental stages obtained were performed with the aid of an ocular micrometer and compared with data reported by different authors (Krull, 1934;Ruiz, 1953;Travassos et al, 1969;Nassi and BayssadeDufour, 1980;Chung et al, 1998;Vianna et al, 2003;Caffara et al, 2011;Sereno-Uribe et al, 2013). Images of the developmental stages were captured with the aid of a microscope Leica DM500 coupled with a Leica ICC50 HD digital camera.…”

A survey of metacercarial infections in commonly edible fish and crab hosts prevailing in Manipur, Northeast India

“…(Yamaguti 1971). A pioneering amount of literature is available on metacercariae of various digenetic trematodes from fishes all over the world (Malek and Mobedi 2001;Arafa et al 2005;SilvaSouza and Ludwig 2005;Vianna et al 2005;Rim et al 2008;Han et al 2008;Sohn 2009;Skov et al 2009;Sohn et al 2009;Gustinelli et al 2010;Thuy et al 2010;Gholami et al 2011), including that from India (Kumari 1994;Jhansilakshmibai and Madhavi 1997;Singh et al 2003;Vankara et al 2011;Shareef and Abidi 2012).…”

Metazoan parasites of Mandi-amarelo Pimelodus maculatus and of Jundiá Rhamdia quelen (Osteichthyes: Siluriformes) of Paraíba do Sul River, Volta Redonda, Rio de Janeiro

“…On the parasite fauna of these siluforms, a number of taxonomic studies as well as studies on the occurrence of these species are of great importance. These include the studies by Cellere et al (2002), Martins et al (2004), and Matos et al (2005) on Myxozoa; Kohn (1990), Kritsky et al (1995Kritsky et al ( , 2000, , Boeger et al (2001), Cohen andKohn (2008), andCarvalho et al (2009) on Monogenea; Kohn and Froes (1986), Kohn et al (1997), Amato, S. and Amato, J. F. R. (1993), Bello et al (2000), Brasil-Sato and Pavanelli (2004), Vianna et al (2005), Kohn et al (2007), and Silva et al (2008) on Digenea; Pavanelli and Santos (1992), Rego et al (1999), and Pertierra (2002) on Cestoda; Brasil-Sato and and Santos et al (2008) on Acanthocephala; Travassos et al (1928), Pinto et al (1974), Kohn et al (1985), Kohn and Fernandes (1987), Vicente et al (1985), Moreira et al (1991), Thatcher (1991), Moravec et al (1993a, b), Moravec (1998), Pinto (1999), Brasil-Sato (2003), and Madi and Silva (2005) on Nematoda; and Boxshall and Montú (1997) Ecological studies of the parasite fauna of P. maculatus were done by Brasil-Sato and Pavanelli (1999), and contain data on the acanthocephalus Neoechinorhynchus pimelodi by Pavanelli et al (1997) on endoparasitic helminthes of species of the Paraná River; by Santos et al (2007) and Albuquerque et al (2008) on metazoan and endoparasites o...…”
