Abstract

The invention discloses a system for characterizing macrophage phagocytosis microorganisms of pompanos. The pompanos are dissected and separated through a surgical knife and tweezers to obtain heads and kidneys; the heads and the kidneys are abraded through a cell sieve to obtain cell suspension containing macrophages, and the macrophages of the heads and the kidneys are obtained through a Percoll solution density gradient centrifugal tube. The survival amount of cells cultured in vitro through a trypan blue dyeing manner is counted, and the survival condition in one week is detected. The system is used for carrying out a phagocytosis experiment, and phagocytosis conditions of nocardia, yeast and the like of the pompanos by the head and kidney macrophages of trachinotus ovatus are determined, and a phagocytosis function is observed. An experiment result of the system shows that the macrophages of the pompanos can be extracted very well, and the survival condition and the phagocytosis condition of the macrophages of the pompanos can be observed very well. The system disclosed by the invention lays a foundation for further researches on physiology, pathology and toxicology of the macrophages of the pompanos.

Description

technical field [0001] The invention belongs to the field of cell biology, and relates to a system for characterizing the interaction between immune cells and microorganisms, in particular to a system for characterizing the microorganisms phagocytized by pomfret macrophages. Background technique [0002] Oval pomfret (Trachinotus ovatus) (Linnaeus), commonly known as golden pomfret, yellow wax pomfret, belongs to Osteichthyes, Vertebrate Phylum, Osteichthyes, Perciformes, Trevalidae, Pomfrets genus. Oval pomfret has a flat side, oval shape, large body, fast growth, and strong disease resistance. In natural waters, pompano pomfret prefers pomfret pomfret to forage and migrate in clusters, vying for food fiercely, mainly feeding on small molluscs and small snails. The large individual weighs 5-10kg, and the meat is tender and delicious. It is a valuable edible fish. [0003] Pomfret ovata is a seawater fish with strong disease resistance, and there were few reports on its di...
