The effect of temperature on cellular reactions of Crassostrea virginica to the injection of avian erythrocytes

摘要: Abstract Intracardial injection of chicken red blood cells (RBC) into the oyster, Crassostrea virginica, at 15–19°C elicited ingestion, digestion, and removal by leukocytes. A rapid response fibroblastlike characteristic cell aggregates were also detected as early 1 hr post-injection. While former was engaged in an unsuccessful attempt to encapsulate laden leukocytes intravascularly, function latter type undetermined. The process disposing oysters under running seawater conditions not noticeably different from that observed standing water conditions. In previously sensitized with cells, a challenge similar following first injection, there no indication activities enhanced. However, it demonstrated oyster remained functionally viable for least 22 days. There is evidence indicating number increases considerably after secondary although specificity this yet be determined. At 6°C, phagocytosis occurred quite extensively, exhibited low digestive migratory activity which resulted far less effective disposal cells. Preliminary observations revealed possible adhesion wall vessels inoculation temperature.
