RESUMEN.Se evalúa la estructura comunitaria de los parásitos de Sciaena deliciosa (Tschudi, 1846), y se analiza si la composición, riqueza, diversidad, prevalencia e intensidad media de sus comunidades parasitarias cambia entre muestras tomadas con 20 años de diferencia en Lima, Perú, entre agosto 1987 y julio 1988 y de agosto a septiembre del 2008 en peces de similar longitud corporal. Los parásitos metazoos fueron colectados y censados empleando las técnicas convencionales. La abundancia total fue de 1,7 (0 a 13) y la riqueza de especies de parásitos fue 0,7 (0 a 2 especies de parásitos por pez). Treinta hospederos mostraron infección con al menos un parásito (60%). Se encontraron siete taxa de parásitos: dos monogeneos Cynoscionicola sciaenae y Hargicotyle sciaenae; un digeneo Helicometra fasciata; un nemátodo Dycheline amaruincai, un acantocéfalo Tegorhynchus sp., y dos copépodos Caligus callaoensis y Lernanthropus huamani. Un análisis comparativo entre los parásitos de S. deliciosa entre 1987-1988 y 2008, muestran una disminución en la prevalencia de Tegorhynchus sp., D. amaruincai, Bomolochus peruensis y Neobrachiella oralis. La intensidad media aumentó para C. americana y Tegorhynchus sp. y disminuyó para C. callaoensis. Las diferencias entre años pudieran estar influenciadas por las variaciones en la temperatura del agua que afectaron los estados larvales y/o reproducción de los copépodos, en la amplitud del periodo de estudio y en el tamaño de la muestra. Palabras clave: parásitos, Sciaena deliciosa, Caligus, Cynoscionicola, Dichelyne, Hargicotyle, Helicometra, Lernanthropus, Tegorhynchus, Perú. Between-year variation of metazoan parasite fauna on Sciaena deliciosa(Tschudi, 1846) (Perciformes: Sciaenidae) in Lima, Peru ABSTRACT. The community structure of parasites on Sciaena deliciosa (Tschudi, 1846), is evaluated and eventual changes are analyzed in the composition, richness, diversity, prevalence and mean intensity of parasite communities on fish specimens that were similar in body length but were sampled 20 years apart (August 1987 to July 1988 vs. August to September 2008) in Lima, Peru. Metazoan parasites were collected and counted employing conventional techniques. Total abundance was 1.7 (0-13) and parasite species richness was 0.7 (0-2 parasite species per fish). Thirsty hosts (60%) were infected by at least with one parasite. Seven parasite taxa were found: two monogeneans (Cynoscionicola sciaenae, Hargicotyle sciaenae), a digenean (Helicometra fasciata), a nematode (Dycheline amaruincai), an acanthocephalan (Tegorhynchus sp.), and two copepods (Caligus callaoensis, Lernanthropus huamani). This comparative analysis (parasites of S. deliciosa in 1987-1988 vs in 2008), showed a decreased prevalence of Tegorhynchus sp., D. amaruincai, Bomolochus peruensis, and Neobrachiella oralis. The mean intensity increased for C. americana and Tegorhynchus sp. and diminished for C. callaoensis. Differences between years could be influenced by variations of sea temperature that affect larval stages and/or cope...

“…To date, 70 species have been described, mostly from the Amazon region (Table 5). According to Van Every and Kritsky (1992), species diversity among Amazonian fish and their parasites may have resulted from lacustrine resource partitioning, similar to that proposed to explain cichlid diversity in some African lakes (LOWE-MCCONNELL, 1987) and Pliocene diversity in lake Idaho (SMITH, 1975 (KRITSKY et al, 1979;KRITSKY et al, 1992;COHEN, 1998;FISCHER et al, 2003;MALTA, 2006;MONTEIRO et al, 2010;COHEN et al, 2012).…”

With the aim of creating an inventory of the metazoan gill parasites of Salminus hilarii in the Taquari River, state of São Paulo, Brazil, five species of monogeneans (Anacanthorus contortus, A. bicuspidatus, Annulotrematoides parisellei, Jainus iocensis and Tereancistrum arcuatus) are reported the first time for this host. A total of 28 fish were sampled quarterly between April 2011 and January 2012, with 10 hosts in a lentic ecosystem and 18 in a lotic ecosystem. Quantitative ecological descriptors (prevalence, intensity of infestation and abundance) were calculated for the purpose to comparing the two ecosystems sampled (lentic and lotic ecosystems). However, no quantitative difference between the lentic and lotic ecosystems was observed. The present study has made available a checklist for species of the genus Anacanthorus and their hosts and geographical distribution in the Neotropical region up to the present time.

“…Granulocytes contribute to wound healing in carp Cyprinus carpio (Iger & Abraham, 1990) and have been reported to be part of the trout immune response to parasitic infections (Sharp et al, 1989). The presence of metazoan parasites in species of sedentary catfishes, astroblepids, callichthyids, hypophthalmids, and loricariids, including Ancistrus from tropical (Amazon) and sub-tropical South American streams has been documented (Freihofer & Neil, 1967;Kohn & Cohen, 1998;Thatcher, 1998). Thus, the presence of EGCs in appreciable amount in the epidermis of Ancistrus can be seen as a system that destroys such multicellular parasites.…”

Histochemistry and functional organization of the dorsal skin of Ancistrus dolichopterus (Siluriformes: Loricariidae)

The structural organization and histo-cytochemical features of dorsal skin of Ancistrus dolichopterus (acari bodo) are the main focus of this work. The epidermis, dermis and subcutis are the principal layers of the skin. The epidermis mainly consists of epithelial and mucous cells. Interspersed between them are lymphocytes, pigment cells, eosinophilic granular cells (EGC), and the taste buds as sensory structures. The high number of EGCs is implicated in general and specific immunological defense from pathogenic bacteria and multicellular parasites. The epithelial cells and mucous cells contain glycoproteins with oxidizable vicinal diols, carboxyl groups and O-sulphate esters and their high secretory activity is correlated with the bottom dwelling habit of this species. A thick stratum laxum contains overlapping osteoderms bearing denticles, and the stratum compactum make the integument thicker to help the fish in negative buoyancy for maneuvering near the bottom and protection. The entire body surface is covered by conical, backwardly directed denticles. These are composed of a dentine cone, surrounding a pulp cavity with the top covered by mineralized cap, and are the true homologues of teeth. These structures provide effective protection from abrasion and enemies. These structural peculiarities and histochemical features indicate additional physiological role of the skin of A. dolichopterus.A organização estrutural e aspectos histo-citiquímicos da pele dorsal de Ancistrus dolichopterus (acari-bodó) são os principais alvos do presente estudo. A epiderme, a derme e a hipoderme são as principais camadas da pele. A epiderme consiste principalmente de células epiteliais e mucosas. Intercalados entre elas estão os linfócitos, as células pigmentares, as células granulares eosinofílicas (CGE), e as papilas gustativas como estruturas sensoriais. Um grande número de CGEs está relacionado em geral com a defesa imunológica específica de bactérias patogênicas e parasitas multicelulares. As células epiteliais e as células mucosas contem glicoproteínas com grupos diol oxidáveis, grupos carboxilas e ésteres O-sulfatados sendo que sua alta atividade secretória está correlacionada com o comportamento bentônico, de fundo, dessa espécie. Um espesso stratum laxum contém osteodermos sobrepostos, parecidos com dentículos, e o stratum compactum que torna o tegumento mais espesso, contribuindo com a flutuação negativa necessária ao movimento perto do fundo e proteção. Toda a superfície do corpo é coberta por dentículos cônicos retrodirecionados. Esses dentículos são compostos por um cone de dentina, envolvendo uma cavidade pulpar e com o ápice coberto por uma capa mineralizada, verdadeiros homólogos dos dentes. Essas estruturas oferecem efetiva proteção contra abrasão e oponentes. Essas peculiaridades estruturais e aspectos histoquímicos sugerem a existência de uma função fisiológica adicional para a pele de A. dolichopterus.
