Occurrence of Chaetogaster limnaei K. von Baer, 1927 (Oligochaeta, Naididae) associated with Gastropoda mollusks in horticultural channels in Southeastern Brazil

Abstract

The aim of this study was to evaluate the presence of Chaetogaster limnaei K. von Baer, 1927 in four species of mollusks collected in irrigation channels of a horticultural garden in the city of Juiz de Fora, Minas Gerais State, Southeastern Brazil. The collections were made from June 2005 to January 2006. Of the four species of mollusks analysed, we could not detect the presence of C. limnaei in Pomacea lineata (Spix, 1827). There were recorded 320 specimens of C. limnaei in association with Aplexa rivalis Mastou & Rackett, 1898, Lymnaea columella Say, 1818 and Biomphalaria sp., the latter having the highest number of associated Naididae.

“…The latter is considered as an endoparasite due to settlement in the renal system and feeding on kidney cells of the host (Gruffydd, 1965) while C. limnaei limnaei lives on the body surface of the host, mainly in the mantle or pulmonary cavity attaching with its caudal suction cup (Stoll et al, 2013;Buse, 1974;Ibrahim, 2007). The association between Chaetogaster limnaei limnaei Baer, 1827 and various species of molluscs has also been reported (Anderson and Holm, 1987;Buse, 1974;Barbour, 1977;Corbi et al, 2005;Martins and Alves, 2010).…”

Occurrence Of Nematodes And Trematode Cercariae In Lymnea Species Of Danmadahun Part Of Jakara Dam, Kano State, Nigeria

“…Different snails can carry the same type of cercaria and a single snail can carry more than one type of cercaria (Kuris and Lafferty ,1994;Sousa, 1993 andDuwa, 2017). Martins and Alves (2010) reported the occurrence of Chaetogaster limnaei K. von Baer, 1927 (Oligochaeta, Naididae) in Gastropoda mollusks in horticultural channels of Southeastern Brazil. Grewal et al (2003) reported that nematodes form diverse associations with slugs and snails that range from paratenic relationships to parasitic or pathogenic relationships and that a majority of the Metastrongyloidea (Order: Strongylida) use molluscs as intermediate hosts for which vertebrates serve as final hosts while a majority of Rhabditoidea (Order: Rhabditida) use molluscs as definitive hosts in which the entire nematode life cycle is completed.…”

“…However, the publication of books in the eightiesspecifically focused on the identification of oligochaetes in Brazil and South America (Righi 1984, Brinkhurst & Marchese 1989, respectively) --encouraged researches as Takeda (1999, Montanholi-Martins & Takeda (1999, , Alves & Strixino (2000), Pamplin et al (2005), Alves et al (2006Alves et al ( , 2008, Gorni & Alves (2008a, Martins & Alves (2010) and Rodrigues et al (2013aRodrigues et al ( , 2013b, which have broadened the knowledge on taxonomic and ecological aspects of these worms in Brazil.…”
