Embodiment 1
[0040] Propagation, isolation and purification of Eimeria tenella oocysts.
[0041] 1. Eimeria tenella Zengcheng strain (ZC strain) was inoculated into five 1-week-old Qingyuan Ma chickens, and the coccidia were checked by flotation in saturated saline on the 5th day after infection (5days post inoculation, 5d p.i.). , collect 6-10d p.i. containing feces containing oocysts.
[0042] 2. Add 2 times the volume of water to dilute the feces, pass through an 80-mesh metal mesh sieve, knead the feces while sieving, add 2 times the volume of water to the feces residue, mix and pass through an 80-mesh metal mesh sieve to collect the filtrate; pass the filtrate through 100 Mesh metal mesh sieve, knead the feces during sieving, and then pass the collected filtrate through a 300 mesh nylon mesh sieve to collect the filtrate.
[0043] 3. Put the filtrate in a centrifuge tube, centrifuge at 1500rpm for 3min, collect the precipitate, and remove the white urate impurities in the upper layer...
Embodiment 2
[0051] Injection site localization.
[0052] Three 1-week-old Qingyuan Ma chickens were used for clinical trials. First, 3 chicks were taken for abdominal autopsy, and the specific positions of the gizzard and the middle of the small intestine (jejunum and ileum) of the chicks were measured using a vernier caliper, and the length, width, and height of the organs from the tail of the chicken keel were recorded respectively. Two more chicks were taken, and the bromophenol blue indicator was sucked up with a 1mL syringe, and injected into the predicted position of gizzard and small intestine in vivo. Finally, the abdominal cavity of the chick was dissected, and the injection of bromophenol blue in the small intestine, gizzard serosa layer and contents were observed, and the exact location of gizzard and small intestine injection was finally determined.
[0053] Before officially entering the inoculation experiment, first understand the 1-week-old No-Ma chicken ( figure 2 A) Th...
Embodiment 3
[0055] Purification and inoculation of Eimeria tenella sporangia.
[0056] 1. Take the sporulated oocysts purified in Example 1, add sterile glass beads at a volume ratio of 1:1, shake and break for 10 minutes, observe under a microscope until all oocyst walls are broken, repeat the observation 3 times, and wait until all the sporangia have escaped. Stop vibrating when going out. Wash 3 times with sterile PBS solution, centrifuge the washed sporangia liquid at 3600rpm for 5min, and discard the supernatant. The precipitate was mixed evenly with 20mL PBS, filtered through a metal mesh sieve with a pore size of 20μm, centrifuged at 3600rpm for 5min, the supernatant was discarded, and 10mL PBS was added to mix well for later use.
[0057] 2. Inject the purified sporangia into the gizzard and small intestine of 1-week-old Qingyuan No-Ma chickens through a 1mL syringe. The gizzard injection dose is 100,000 sporangia / feather; the control group is set up and an equal volume of PBS is...
