In Vitro Interactions of Asian Freshwater Clam (Corbicula fluminea) Hemocytes and Cryptosporidium parvum Oocysts.
Corbicula fluminea hemocytes phagocytosed infectious oocysts of Cryptosporidium parvum in vitro. After 15, 30, 60, 90, and 120 min of incubation, averages of 35.8, 58.0, 69.7, 77.7, and 81.6% of the oocysts were phagocytosed by 24.3, 70.0, 78.5, 87.3, and 93.0% of the hemocytes, respectively. A single clam can retain by phagocytosis an average of 1.84 x 10(sup6) oocysts per ml of hemolymph. C. ...
متن کاملPopulation genetics of the Manila clam (Ruditapes philippinarum) introduced in North America and Europe
Globally, the Manila clam (Ruditapes philippinarum) stands as the second most important bivalve species in fisheries and aquaculture. Native to the Pacific coast of Asia, it is now well-established in North America and Europe, where its on-going management reflects local economic interests. The historic record of transfers spans the 20th century and suggests sequential movement from Japan to No...
متن کاملOxidative stress and histological changes following exposure to diamond nanoparticles in the freshwater Asian clam Corbicula fluminea (Müller, 1774).
Recently, the scientific community became aware of the potential ability of nanoparticles to cause toxicity in living organisms. Therefore, many of the implications for aquatic ecosystems and its effects on living organisms are still to be evaluated and fully understood. In this study, the toxicity of nanodiamonds (NDs) was assessed in the freshwater bivalve (Corbicula fluminea) following expos...
متن کاملStructure of new carotenoids from corbicula clam Corbicula japonica.
Six new carotenoids, named corbiculaxanthin (1), corbiculaxanthin 3'-acetate (2), 6-epiheteroxanthin (3), 7',8'-didehydrodeepoxyneoxanthin (4), cyclopyrrhoxanthin (5), and hydratoperidinin (6), were isolated from the corbicula clam (Shijimi in Japanese), Corbicula japonica. Their structures were determined by chemical and spectral data.
متن کاملEffects of the invasive Asian clam Corbicula fluminea on the littoral communities of Lake Constance
The Asian clam Corbicula fluminea, originating from Southeast Asia, was first recorded in Lake Constance in 2003 and developed local mass occurrences afterwards. Effects of harsh winter conditions in 2005/2006 associated with a strongly decreasing water level were studied at 3 different depths at and below the mean low water level (MLL, MLL -1 m and MLL -3 m). Low winter temperatures produced a...
