Abstract: This study reports for the first time infection with Hysterothylacium sp. larvae in the ornamental fish Hyphessobrycon eques from the Paranapanema River, Jurumirim Reservoir, São Paulo State, Brazil. A sample of 33 specimens of H. eques was collected in October, 2011. Four specimens of H. eques were parasitized by Hysterothylacium sp. larvae in the intestine and coelomic cavity, with prevalence of 12.1%, mean intensity of infection of 1, and mean abundance of 0.121 ± 0.05. A total of 40 unidentified free-livin… Show more

“…In freshwater fishes from Brazil, Hysterothylacium sp. larvae have been reported in Rhaphiodon vulpinus Agassiz, 1829, Salminus maxillosus Valenciennes, 1850, Galeocharax knerii (Steindachner, 1879), Hypophthalmus edentatus Spix & Agassiz, 1829, Loricariichthys sp., Plagioscion squamosissimus (Heckel, 1840), and Crenicichla lepidota Heckel, 1840 from the Paraná River, State of Paraná (Moravec, Kohn, & Fernandes, 1993), in Gymnotus carapo Linnaeus, 1758 and Leporinus friderici (Bloch, 1794) from the upper Paraná River floodplain (Takemoto et al, 2009), in Brachyplatystoma filamentosum (Castelnau, 1855), Brachyplatystoma rousseauxii (Castelnau, 1855), and Oxydoras niger (Valenciennes, 1821) from Colares and Vigia Island, State of Pará (Rodrigues et al, 2015), in Arapaima gigas (Schinz, 1822) from fish farms from the State of Amazon (Andrade-Porto et al, 2015;Azevedo, Morey, & Malta, 2017), in Hyphessobrycon eques (Steindachner, 1882) from the Paranapanema River, State of São Paulo (Acosta & Silva, 2015), and in Hoplias malabaricus (Bloch, 1794) from the Jacaré-Pepira River and Jacaré-Guaçú River, State of São Paulo (Leite, Pedreira-Filho, Azevedo, & Abdallah, 2020). According to Moravec et al (1993) these genera might be carried from marine to freshwater environments by some migratory fishes.…”

“…For example, Camallanus cotti Fujita, 1927, a native nematode from Japan was first recorded in Brazil infecting Poecilia reticulata Peters, 1859 (Alves et al, 2000), assumed to be introduced along with the introduction of the exotic poeciliid fish species. Fish may be intermediate, paratenic or definitive hosts for different species of nematodes (Molnár, Buchmann, & Székely, 2006;Acosta & Silva, 2015;Oliveira et al, 2017;Tavares-Dias et al, 2017;Hoshino et al, 2018). In general, larvae are more pathogenic than adult forms, since they may migrate through various host organs.…”

“…Species of camallanids can feeding on blood causing anemia in the hosts. Consequently, high levels of infection by nematode larvae may be harmful to health of hosts (Molnár et al, 2006;Acosta & Silva, 2015), mainly for small ornamental fish as H. takasei and H. amapaensis. In H. takasei, there was higher level of infection by Procamallaunus (Spirocamallanus) inopinatus Travassos, Artigas and Pereira, 1928 and Camallanus sp.…”

“…Nevertheless, the presence of these exuberant red color (Fujimoto et al, 2013). Despite being an important species for the aquarium fishery industry, there is little information about the parasite fauna of H. eques (Acosta & Silva, 2015). Fujimoto et al (2013) and Acosta & Silva (2015) are the only two assessment of its parasitic fauna reporting the occurrence of cysthacanths (Acanthocephala) of Quadrigyrus nickoli Schmidt & Hugghins, 1973 and Hysterothylacium sp.…”
