Prevention and treatment of White Eye Disease of Water Turtle in Guangxi

Guangxi imitating water turtles, commonly known as stone turtles. With the development of aquaculture, the diseases of water turtles have increased in recent years, and "white eye disease" is one of the more common and harmful epidemics. The prevention and treatment methods of "white eye disease" are introduced as follows.

First, symptoms of white eye disease: the sick tortoise eyes are inflamed and congested, the eyes are enlarged, the eyelids and nasal mucosa are eroded, there are white spots or abnormal objects in the eyes, and the appearance of the eyes is covered by yellow and white secretions, commonly known as "white eye disease". The sick tortoise is lethargic, slow to respond, slow to move, scratches his eyes with his forelimbs from time to time, often floats on the water or climbs to the edge of the pool (plate), and does not eat. In severe cases, the sick turtle has difficulty breathing, opens its mouth from time to time, and exudes mucus at the corners of its mouth, unwilling to go into the water. At this time, the sick tortoise is thin, sunken eyes, improper handling will cause eye blindness. Because the sick tortoise did not eat for a long time, and the internal organs were infected by bacteria, it eventually collapsed and died. The disease mainly occurs in juvenile turtles weighing 12 to 30 grams. The disease begins within a month after the purchase of turtle seedlings, and the onset period is longer, lasting about 20 days from onset to death. It is contagious and develops rapidly.

Second, prevention and control methods: 1. Preventive measures: the turtles purchased by ① should be disinfected with different drugs once a day for the first 3 days, such as soaking in 3% salt water, 30PPM potassium permanganate solution, 2PPM fish bacteria, 20PPM furazolidone and 3PPM chloramphenicol solution for 20 minutes, and use drugs alternately to kill bacteria, prevent injured skin infection and promote wound healing. ② feed should be chopped up when feeding turtles, and the feed size should be smaller than the mouth crack of the turtle seedlings to prevent infection caused by scratching the skin around the corners of the eyes when the turtles use their forelimbs to help bite food. Because the early symptoms of ③ are not obvious, it is not easy to be found. After buying turtle seedlings, pay attention to observation when feeding and changing water, take out the turtle seedlings that have eye problems or do not feed and often float on the surface of the water in time, isolate and raise them specially, and strengthen the observation of food intake. Even if the eyes are not inflamed and swollen, turtles that do not eat for more than two days are infected with bacteria and should be given timely drug treatment. When ④ feeds and changes water, the water temperature should be kept at 2931 ℃, the water temperature difference should not exceed ±2 ℃, and the water quality should be clean, so as to keep the turtles in good condition and improve their disease resistance.

two。 Drug treatment: according to the symptoms, drug treatment should be divided into the combination of external and internal injection.

External use of ①: when turtle seedlings are found to be suffering from white-eye disease, the diseased turtles should be isolated and treated separately; all turtle seedlings should be soaked and disinfected together with the above-mentioned drugs and containers to prevent the disease seedlings from spreading infection. For turtles with eye inflammation, use 1% rivanol solution, chloramphenicol, erythromycin, ciprofloxacin, rifampicin eye drops or rinse. 2-3 times a day, drip clean and dry on the plate for 3-5 days. Due to the different infection bacteria, the drug should be changed in time when it is found that the drug is ineffective.

② should be treated orally with amoxicillin, ciprofloxacin, ofloxacin and duck liver for 3-5 days.

Turtles with severe ③ condition without feeding can be injected alternately with 0.5mg piperacillin sodium and glucose injection at the base of the extremities, each turtle vaccine is injected 0.15ml / 0.3ml every other day, 3 times continuously for 4 times as a course of treatment. If there is no improvement, consider changing the dressing.
