متن کاملThe Importance of Bacteria in Laboratory Experiments on Rearing the Larvae of Ostrea Edulis (l.)
Observations made by the writer during the summer of 1955 suggested that the density of the bacterial flora which develops when oyster larvae are reared in small glass vessels is inversely correlated with the number of spat settling (Walne,1956). From the nature of the observations it could not be determined whether the bacteria were affecting the development of the larvae or whether the proper...
متن کاملDetection of Bonamia ostreae and B. exitiosa (Haplosporidia) in Ostrea edulis from the Adriatic Sea (Italy).
The flat oyster Ostrea edulis L. is widespread along the Italian coasts. In particular, the Manfredonia Gulf (Adriatic Sea) represents an important site where natural beds subsist. Previous monitoring conducted in 1990 by light microscopy and ultrastructural studies revealed the presence of Bonamia-like microcell parasites in some flat oysters: following this observation, a new sampling of O. e...
