More importantly, the strong host response produced by oysters against parasites seems to be the principal factor structuring metazoan parasite communities of oysters. The host response against parasites is suggested as the principal factor responsible for depauperate parasite communities of oysters. Each tray was split into two parts and contained 100 oysters from two different families. After inoculation, both challenged and control oysters were left overnight, out of seawater, to promote retention of the parasites, and then returned to seawater. Copepods were rinsed in filtered sea water and were directly added in tanks containing uninfected oysters. We therefore cannot assume that experimental conditions were optimal for transmission of the parasite from oysters to copepods. The dead oysters were found to have light to moderate infection. Four oysters out of 90 died among the challenged group but no mortality was observed among the control group. Comparable results were seen for individual oysters with medium supplemented at 0.03 mg/ml (data not shown). In fact, oysters and many other kinds of shellfish are said to be larger at the time when the moon is waxing. The metazoan parasite communities of all four oysters species were dominated by allogenic species. Many types of seafood, especially oysters, shrimp and the other crustaceans are often eaten raw or undercooked. Changes were corrected using associated determinations within control pots without oysters. In this study, the monitored oysters were too young to experience significant parasite pressure. Genetic di ersity of selected flat oysters following this bottleneck. An outbreak of viral gastroenteritis associated with eating raw oysters. Two different indices were used to characterize the genomic diversity of individual oysters. In view of the close proximity of these oysters this fact is not surprising. At the end of the experiment, flat oysters were analysed by in situ hybridization. At the end of the experiment, oysters were analysed by in situ hybridization. No significant variation was observed in control oysters. Important differences in the number of parasites were observed between the 5 oysters of each sampling day. The basal metre or so of the clay is sparsely shelly, including small nuculids and oysters. Outbreaks due to contaminated food [7], particularly oysters [8-10], and water [11-13] have been described. The control experiment was designed as described above, but included uninfected flat oysters also placed on a mesh. Moreover, the values for these two parameters were characterized by an extended individual variability, both in challenged and in control oysters, which may hinder differences. An outbreak of viral gastroenteritis associated with adequately prepared oysters. At a banquet, servants are shucking oysters as fast as they can be consumed. Shellfish, and in particular oysters, cultured in faecal/ sewage contaminated seawater have been responsible for many outbreaks of viral gastroenteritis. All metazoan parasite communities of oysters had few species and low density of individuals. The industry is carried on largely by women who have small farms of about 1,000,000 oysters. The food implicated in most reported cases has been raw oysters. The duration of the experiment was 2 months, with 9 samplings of 5 challenged and 5 control oysters on each occasion. Attempts to infect oysters experimentally have been unsuccessful and led to the hypothesis of a complex life-cycle involving several hosts. Five infected flat oysters were placed on a 500 m mesh located in the upper part of the tank. They were likely introduced with infected oysters imported for culture. Most are parasites of oysters, presumably introduced with infected aquaculture stocks. The operations were severely hampered by the almost complete absence of oysters. The bottom of the enclosure was specially covered with oysters of various ages. Processes structuring helminth communities of marine and freshwater gastropods are different from those found in metazoan parasites of oysters because of the high hostspecificity of digeneans parasitizing gastropods. A review of introductions of exotic oysters and biological planning for new importations. Under these circumstances it is easy to imagine that the ripe proglottides drop in the close vicinity of the oysters on which the fish concerned normally feed. Additionally, high concentrations of lysozyme-like substances occurring in the oyster's mantle are responsible for a lytic effect against a great variety of microorganisms, including cercaria and other helminth larval stages.
