Description
Technical Field
The invention relates to the technical field of sterile mouse preparation and breeding, in particular to an integrated isolation device for sterile mouse preparation and breeding.
Background
In recent years, as microbiology has rapidly developed, it is becoming clear that we have come to the form of "superlife" where each individual is a symbiont of the body with a large number of microorganisms. The microorganisms are mainly distributed in tissue parts or passages of the body, such as respiratory tract, digestive tract, urogenital tract, body surface and the like, which are directly communicated or contacted with the external environment; among them, the intestinal microorganisms are various and large in number, accounting for 78% of the total microbial population of the organism, and play a very important role in the pathological or physiological metabolic processes.
In view of the fact that intestinal microorganisms can be widely involved in various life metabolic activities of human beings and animals from life to death, the research on the composition structure and function of the intestinal microorganisms and the interaction relationship with a host has a very profound practical significance.
In order to carry out intensive studies on the intestinal microbiota, humans have developed a large number of sterile animal models. The sterile mice have the advantages of easiness in genetic engineering operation and humanization treatment, convenience in feeding and management, high growth speed, short breeding period, large-scale production and the like, and have good portability and reproducibility in combination with the intestinal microbiota, so that the sterile mice are widely applied to verification of correlation and causal relationship between phenotypes of human major diseases, animal husbandry economic traits and the like and the intestinal microorganisms, exploration of biological functions of different intestinal microorganisms and the like.
Aseptic preparation is a key link for obtaining aseptic mice of different strains or different genetic engineering and is divided into two methods, namely hysterectomy and embryo transplantation. Currently, hysterectomy is the mainstream method for preparing sterile mice, mainly due to the relatively low technical threshold of the method, and the theoretical basis and practical basis are that the placenta has a barrier effect on microorganisms.
Compared with the uterine resection method, the embryo transplantation method can well reduce the pollution risk, improve the milk leaving rate (99-100%), and is more convenient, quicker and more efficient in preparing the genetic engineering sterile mice. However, the technical requirements are high, the stereomicroscope and the isolator are required to be used in combination for preparing the sterile mouse by using the embryo transfer method, and the current combination methods mainly comprise three methods: one is to put the body microscope into a clean bench after fully sterilizing the body microscope by means of the clean bench, and connect the bench with an isolator. After completion of embryo transfer surgery in the clean bench, the pseudopregnant mice were transported back to the isolator for feeding and testing. However, the preparation method has larger pollution risk, complex operation and low efficiency; the second method is that an isolator (with the top made of transparent glass) made of hard materials is combined with an external stereomicroscope, so that the technical requirement of embryo transplantation for preparing a sterile mouse is met, however, the hard isolator has the defects of large size, corrosion resistance, high pollution risk and high manufacturing cost, is not suitable for being used in large-scale production, and in order to meet the working distance requirement of the stereomicroscope, a convex object stage is required to be arranged in the isolator, and the stereomicroscope is placed on the top end surface of the isolator, so that the working distance requirement between the object stage and an objective lens on the stereomicroscope can be met, although the stereomicroscope does not need to be sterilized, the isolator is internally provided with the convex object stage, so that an arm of an operator is required to keep the same height as the convex object stage for operation during operation, the arm of the operator is required to be operated for a long time, the arm of the operator is sour and painful, and the use feeling is poor; the third method is to transmit the sterilized integral microscope into the isolator for use, and has the difficulty that the integral microscope is difficult to meet the use requirement of not only completely sterilizing but also not damaging the parts of the integral microscope. Therefore, the current sterile mouse preparation method is difficult to find that the preparation efficiency is low and a special isolator is lacked, so that the aim of preparing the sterile mouse in large-scale production cannot be completely met, and the wide application and further development of the sterile mouse are limited.
Therefore, the technical personnel in the field need to solve the problem of how to provide an integrated isolation device for preparing and breeding a sterile mouse, which has the advantages of low use cost, simple structure, small volume and convenient operation, and can obviously improve the scale production and preparation efficiency of the sterile mouse.
