“…The presence of a variable number of Nematopsis oocysts per host cell (phagocyte), usually 1 to 2, with each oocyst containing a single uninucleate sporozoite, coincides with observations made by Azevedo and Matos (1999) and Carballal et al (2001).…”

“…This effect and small alterations of gill filaments, as a result of lesions, were also observed by Carballal et al (2001) in C. edule with a high infection degree. Pearls production or calcareous sediment in the internal shell surface was associated with Nematopsis oocysts presence in the mantle tissue of Mytillus edulis (Lauckner, 1983).…”

“…Oocysts occurrence of Nematopsis in the connective tissue of marine bivalves, mainly in the gills, is widely registered (Nascimento et al, 1986;Azevedo and Cachola, 1992;Bower et al, 1994;Azevedo and Matos, 1999;Carballal et al, 2001). Nevertheless, the pathogeny of this gregarine is very doubtful.…”

“…Protozoans of Nematopsis genus (Schneider, 1892) have been reported in many marine bivalves (Azevedo and Cachola, 1992;Carballal et al, 2001;Winstead et al, 2004;Cremonte et al, 2005). Those parasites are often observed in the gills and mantle of mollusks and complete their life cycle in the gut of marine arthropods (Bower et al, 1994).…”

Mangrove oysters Crassostrea rhizophorae were sampled monthly in the estuary of Jaguaribe River, on the east coast of Ceará State, Brazil, between August, 2000 and December, 2001, making up 170 individuals. The water temperature varied from 26 to 30 °C and salinity from 21 to 42‰. The animals' size ranged from 3.4 to 7.2 cm height. Macroscopical and histopathological analyses were carried out in the oysters' tissues. The histological exams showed protozoans and metazoans of genera Nematopsis and Tylocephalum, respectively. Nematopsis prevalence varied from 60 to 100% and it was higher in the gills and mantle. The oocysts presented a mean size of 11.5 µm (±1.32) length and 9.1 µm (±1.06) width (n = 30), up to 3 oocysts/phagocyte having been observed. Several animals presented focal hemocitical reaction.

“…Trata-se de um ciliado do gênero Trichodina Ehrenberg, 1830 (Oligohymenophorea, Peritrichia, Mobilida). Espécies desse gê-nero estão relatadas como patogênicas para alguns bivalves e inócuas para outros (LAUCKNER 1983, BOWER et al 1994, CARBALLAL et al 2001. Em ostras do gênero Crassostrea, esses organismos produzem lesões no epitélio branquial e interferem no funcionamento normal das brânquias (FIGUERAS & VILLALBA 1988).…”

Berbigões, Anomalocardia brasiliana (Gmelin, 1791), de bancos naturais da Ilha de Santa Catarina e região continental adjacente (SC, Brasil), foram examinados quanto a presença de simbiontes. Holothuriophilus tomentosus (Ortmann, 1894) (Brachyura), Sphenia antillensis Dall & Simpson, 1901 (Bivalvia) e poliquetos espionídeos (Polychaeta) foram observados macroscopicamente. A análise das secções histológicas evidenciou esporocistos de trematódeos (Digenea), um metacestóide (Cestoda) e dois ciliados (Ciliophora).
