Cause of disease: eye injury or bacterial infection caused by eye irritation caused by poor water quality. The disease is more common in red-eared turtles, soft-shelled turtles, yellow-throated soft-shelled turtles, yellow-edged soft-shelled turtles, eye-spotted soft-shelled turtles, etc., and the incidence of young turtles is higher. The onset season is spring, and autumn and spring after wintering are the epidemic peaks.

Symptoms: the eyes of the sick turtle are inflamed and congested, and the eyes are swollen. The cornea and nasal mucosa of the eye are eroded by inflammation of the eye, the outside of the eye is covered with white secretions, and there is inflammation inside the eye. Sick turtles often wipe their eyes with their forelimbs, which makes them slow down and stop eating. In severe cases, the sick turtle went blind, and finally the turtle was thin and died. Some sick turtles have only one eye at the beginning of the disease. If no measures are taken, symptoms will soon appear in the other eye.

Prevention and control methods:

1) Strengthen feeding management. Before and after overwintering, animal livers (bovine liver, sheep liver, rabbit liver, dried chicken liver, etc. ) feed regularly to strengthen nutrition and enhance disease resistance.

2) Disinfect the turtle-raising equipment, and soak the glass jar and aquarium in 10% salt water for 30 minutes. The tortoise is washed with clear water before being raised.

3) soaking in furacilin (or furazolidone) solution is not only a preventive measure, but also an early treatment. The concentration of young turtles is 20 mg/L, and the concentration of young turtles to adults is 30 mg/L. The soaking time depends on the water temperature. If necessary, soak 1 time (40 minutes) every day for 3-5 days.

4) Take the sick turtles and soft-shelled turtles out of the soil pool or cement pool where the soft-shelled turtle water is disinfected for further treatment. For the sick soft-shelled turtle or soft-shelled turtle in the pond, apply bleaching powder with the concentration of 1.5-2.0g/m3 and spread it all over the pond.

5) intraperitoneal injection of streptomycin (or kanamycin) is 200,000 units per kilogram of turtle weight. After the injection, the patient was temporarily isolated for 5-6 days. The patient's condition did not improve significantly, and he was given a second injection with the same dose. If the sick turtle is wintering, it has stopped eating. Each sick turtle was injected with 0.5 ml of glucose solution (medical, containing 50% sugar) and streptomycin. The effect is very remarkable.

6) Rivanol1%aqueous solution is suitable for Rivanol, also known as Rever's ear, which is a surgical drug. Apply it to the affected eyes for 40-60 seconds each time, 1 time every day for 3-8 days. This method should be used when the green turtle is sick, because soaking and washing with furacilin and furazolidone is very toxic to soft-shelled turtle and soft-shelled turtle, but it is very toxic to filamentous green algae of green turtle, and soaking and washing will kill filamentous green algae.

7) The usage of furacilin (or furazolidone) 1% aqueous solution is the same as that of rivanol solution. The green turtle should be sick by permanent magnet method. When applying the liquid medicine, don't let the liquid medicine come into contact with filamentous green algae. After applying the medicine, put the green turtle into a white basin filled with clear water and turn red for half a minute, and immediately change the water 1 time. If there is no yellow liquid medicine in the water, it can be fed in a sterilized tank. Furacillin is not as effective as rivanol, but it is cheap. Rivanol should be used in severe cases.

8) As a preventive measure, the concentration of furacilin (or furazolidone) solution in the whole pond is1.2-1.5g/m3; Use 2.0-2.5g/m3 for treatment. After spraying in the whole pond, the efficacy generally lasts about 10 days. If the condition does not improve obviously after application, the same concentration can be sprayed again in the whole pool on the first 1 1 day. In severe cases, the drug can be injected first, and then the liquid medicine can be smeared or soaked. You can also apply or soak the liquid medicine first, and then sprinkle the medicine all over the pool, which has more obvious curative effect.

9) Spray erythromycin 1.5-2.0g/m3 in the whole pool.

10) Other antibacterial drugs, Medrol, soluble in feeding edema, each glass goldfish bowl contains 1 tablet. This method is suitable for green turtles. Streptomycin can also be dissolved in water, so that every 1 mg of water contains 65438+ 10,000-200,000 international units, which is suitable for treating diseases of green turtle and other small water turtles.
