The metacercaria is named as the metacercaria mansoni, is long and white, has different lengths of 0.3-105.0 cm and has strong stretching capacity. The head of the lacerated larva expands, the center of the lacerated larva has an obvious recess, the larva is not segmented but has irregular transverse folds, and the rear end of the larva is mostly in a shape of a blunt circle.
The human infected larva of the. After being eaten by people, the sparganum is most commonly parasitized in tissues and organs such as subcutaneous tissues, muscles, liver, lung, brain and the like of human bodies, and migrates in all tissues and organs of the organisms to cause the sparganosis, so as to form the fascicular or space occupying lesion. Clinical symptoms caused by different infected parts of the sparganosis are different, specific clinical manifestations are lacked, and misdiagnosis and mistreatment are common. Researches on the occurrence mechanism, the immune characteristics, the serodiagnosis, the clinical treatment and the like of the sparganosis all require stable animal models infected by the sparganosis and a large amount of standardized species resources with stable biological properties. However, the now experimental sparganosis mainly collected from naturally infected second intermediate host frog or tadpole, and cannot obtain live larva at any time due to seasonal factors, so that the sparganosis needs to be preserved in vitro for a period of time for convenient observation and detection.
SUMMERY OF THE UTILITY MODEL
In the process of researching the coenuruses, the coenuruses are generally required to be stored in vitro for a period of time to keep the coenuruses fresh and alive, so as to be convenient for observation or detection; at present, the coenuruses are generally stored in vitro in a short time by adopting a glass culture dish, but the glass culture dish has single function and is easy to transmit light, and the coenuruses are not beneficial to survival under strong light; in addition, in the process of storage and culture, because the coenuruses are required to be frequently transferred to replace the culture solution, the survival rate of the coenuruses is further reduced, and the glass culture dish is difficult to carry out in-vitro long-time culture and storage on the living bodies of the coenuruses; aiming at the problems, the utility model provides a culture dish for in-vitro conservation of the sparganosis, which has simple structure and convenient use, and can provide a more stable environment for in-vitro culture and storage of the sparganosis so as to prolong the in-vitro survival time of the sparganosis.
