Bacterial intestinal hemorrhagic disease of money tortoise

Bacterial intestinal hemorrhagic disease of money tortoise is a kind of intestinal disease caused by conditional pathogenic bacteria. The disease is usually caused by unclean water quality, pollution or eating spoiled residual bait. In March 1997, the money tortoise in an aquaculture farm in Mule Town was characterized by diet, refusing to eat, not moving, mouth and nose bleeding, and even catching it by hand without running away. The case was diagnosed as bacterial intestinal hemorrhage by clinical and anatomical examination. The details are as follows:

1. Morbidity

The aquaculture farm raises 57 money turtles, each weighing 250 grams to 400 grams, living in the same pool. When there is little water in the pool, only appropriate water is added, and the water has not been changed for a long time. There are a lot of whitish, rotting fish sausages and other things deposited at the bottom of the turtle pond, which stirs up the pond water and smells fishy smell. There were 17 turtles successively, including 12 with mild disease and 5 with serious disease.

2. Clinical symptoms

Lack of energy, loss of appetite, do not like activities, in serious cases, live alone from the water, do not eat or move, when using hands to grab its head, limbs, do not contract or contract slowly, nose, mouth and margin shield bleeding.

3. Anatomical examination

Two seriously diseased turtles were examined and it was found that there were dense hemorrhagic spots on the intestinal wall.

4 prevention and control measures

4.1 change of water

Drain all the old water from the pool, thoroughly remove the residual bait and turtle droppings, re-inject clean well water; catch all turtles, wash them with clean water, and put them back into the pool. Keep changing in fresh water twice a day. And quarantined the sick turtles.

4.2 treatment

① each diseased tortoise was injected with penicillin 50 000 units once a day for 2 days, and continued with 20% sulfadiazine sodium injection 1 ml once a day for 2 consecutive days. All of them were injected intramuscularly at the base of the hind leg.

② was fed to each turtle with 0.1g oxytetracycline mixed with bait twice a day for 7 days.

Results 4 turtles who were seriously ill and could not eat were eliminated and 13 recovered.

5 knot

5.1 through clinical observation and anatomical examination, it is preliminarily concluded that the intestinal bleeding of the money tortoise in the farm may be caused by bacterial infection.

5.2 A large amount of excreta of residual bait and turtle is accumulated in the pool water, and after decay, it odors and pollutes the water, resulting in a large number of bacteria and pathogens, and bacteria enter the body through the mouth and cause disease.

5.3 important measures to prevent bacterial intestinal bleeding of money turtles are to pay attention to changing water frequently to ensure that the water quality is fresh and good, so as to prevent the deterioration of water quality from causing bacteria to pollute the turtles; the spoilage, spoilage and odorous baits accumulated in the turtle ponds often carry bacteria, and the accumulated materials should be removed in a timely manner to prevent the turtles from eating these residual baits with bacteria.

5.4 after the occurrence of bacterial intestinal hemorrhage in the tortoise, antibiotics are introduced in this paper, and good results can be obtained. However, cases that cannot be eaten are difficult to cure, so they must be detected and treated as early as possible.
