1. How to treat fish tapeworm disease?

Tongue-shaped tapeworm disease is a fish disease caused by the sparganosis of tongue-shaped tapeworms and double-threaded tapeworms of the family Linguiniformes that parasitize many freshwater fish such as crucian carp, silver carp, bighead carp, grass carp, whitebait, Taihu shortnose whitebait, schizothorax, Cobitidae, Hypocritinae and Leucinae.

2. How to treat fish printing disease?

Measures for treating fish printing disease: (1) 1 mg/L of bleaching powder or 0.3-0.5 g/m3 of trichloroisocyanuric acid, spray all over the pond for 2-3 times; (2) When the broodstock are sick, the affected area can be cleaned with 1% potassium permanganate solution, or the moisture on the lesion can be absorbed with gauze, and then smeared with chlortetracycline or tetracycline ointment. (3) When the disease is serious, it is necessary to inject streptomycin sulfate intramuscularly or intraperitoneally, 20 mg per kilogram of fish; or chlortetracycline, 5,000 international units per kilogram of fish.

3. What is pigeon blood protozoan disease?

Pigeon blood protozoan disease is a blood protozoan disease caused by the invasion of pigeon red blood cells by pigeon blood protozoa in the class Sporozoa and the family Plasmodium.

The pigeons experience systemic discomfort due to the rupture of infected red blood cells, the release of protozoan merozoites and metabolites and red blood cell fragments into the bloodstream

4. How to prevent and treat rabbit encephalitis protozoan disease?

Coccidiosis usually does not occur between 1 and 3 months, but is most common in the rabbit's infancy (1 to 6 months). In adulthood, if the adult rabbit has a poor physical condition due to an unreasonable diet, it will also develop an attack after infection.

I have seen a case where a rabbit over 9 months old was infected with coccidia.

Generally speaking, even if infected after the age of 2, coccidia is less likely to occur. Of course, those with particularly poor physical constitutions will still be susceptible to the disease.

The prevention of coccidia mainly relies on source control.

First of all, after bringing the rabbit home, immediately test its feces to determine whether it carries coccidia. If it does, it must be given medication. Oral medications generally include "Xuexilishat" and "Baiqiuqing". Among them, "Xuexilishat" seems to have developed resistance in recent years, so "Baiqiuqing" is currently the first choice.

Coccidia vaccination is also an option, but the mortality rate is generally 10% (that is, regardless of whether the rabbit is infected with coccidia, the mortality rate after vaccination is about 10%). It is more commonly used in rabbit farms, but it is not recommended for ordinary families to keep pet rabbits.

Secondly, the rabbit's living environment must be clean and cleaned every day. If there is more than one rabbit in the house, each rabbit must be placed in a cage. This will not only prevent the spread of coccidia infection, but also effectively control other malignant infectious diseases (such as buss, E. coli, etc.).

Finally, the diet must be reasonable and correct, ensuring that the daily diet is "grass (mainly) + rabbit food (supplementary) + clean boiled water". Vegetable and fruit peels and rotten leaves are prohibited before adulthood. After adulthood, give a small amount of clean vegetables and fruits every day to ensure that the rabbit has good physical fitness and can effectively prevent coccidiosis and various other diseases.

5. Sporozoan disease in fish?

First, we need to distinguish the type of disease and the type of fish we are raising. Sporozoa are a large class of pathogenic protozoa, and there are many types. There are many fish disease sporozoa, which can parasitize the mesentery, gills, brain, spinal cord, and internal organs. Iodine bubble worms are the main pathogenic organisms of carp. Generally, prevention and treatment are the main measures. It is too late to infect the fish. Prevention and control methods:

1. Thoroughly clean the pond with quicklime, etc. to inhibit the massive reproduction of spores and reduce the occurrence of this disease;

2. Before stocking the fish, add 500g of potassium permanganate to 1 cubic meter of water, stir to fully dissolve it, and make a solution with a concentration of 500mg/L. Soak the fish for 30 minutes, or add 500g of lime nitrogen to 1 cubic meter of water, stir to make a suspension, and soak the fish for 30 minutes. Treatment of myxosporean disease This disease is caused by myxosporeans parasitizing the skin, gills, intestines and nervous system of fish. The parts of the fish disease have cysts, which are grayish white dots and tumors. Common myxosporeans include pancake-shaped iodine spores, wild carp sulfonium spores, crucian carp iodine spores, silver carp iodine spores, etc. Symptoms: The sick fish are emaciated, the body color is black, they swim alone or restlessly and wildly, and they are extremely harmful to the fish from October to February of the following year. Treatment methods: 1. Sprinkle 1 jin of 90% crystal trichlorfon per mu of water in the whole pond, and sprinkle it again after 3 to 4 days. 2. For every 10,000 fish or 100 jin of fish, mix 75 grams of edible sulfur powder with feed and feed it for one week. 3. Add 10 grams of 90% crystal trichlorfon to each jin of feed to feed fish, which can cure intestinal parasitic myxosporeans. This method is also effective for ringworm disease. Compare the following information, and it is best to consult an expert for specific practices. Other classifications 1. Madness disease is also known as silver carp madness disease, crazy knife, and silver carp iodine bubble disease. It is caused by silver carp iodine bubble parasitism in various organs and tissues of silver carp, especially the nervous system and sensory organs, such as the brain, spinal cord, parasitic lymph fluid in the cranial cavity, nerves, olfactory system, balance, and auditory systems. Silver carp fry can be infected as soon as they emerge from the membrane. At present, in production, it mainly harms silver carp of full age. When the disease is serious, it can cause a large number of sick fish to die; the meat of sick fish is not fresh and has a strong fishy smell, and it is very thin, so the commercial value of the fish that have not died is also seriously affected. This disease occurs in rivers, lakes, reservoirs, and ponds across the country, especially in Hangzhou, Zhejiang. When seriously infected, the sick fish are extremely emaciated, with a large head and a small tail, with an upturned tail. The weight is only about half of that of a healthy fish. The length of the head is 2.95 times the height of the tail stalk (2.2-2.3 times for healthy fish), and the body color is dull and lusterless. The sick fish swim alone in the water, often jumping out of the water and diving back into the water, repeating this many times and dying. When dying, the head often burrows into the mud. Some swim sideways and die due to loss of balance and feeding ability, so it is called crazy disease. When the fish body is cut open, white cysts of varying sizes visible to the naked eye can be seen at the place where the silver carp iodine vesicles parasitize; the liver and spleen are atrophied, there is ascites in the abdominal cavity, and the vagus lobe of the cerebellum is significantly congested; the sick fish are severely anemic. 2. Pancake iodine vesicle disease is a serious fish disease during the grass carp seedling breeding period. It is caused by the parasitism of the pancake-shaped iodine bubble worm, which mainly parasitizes the intestinal wall of grass carp, especially the lamina propria and submucosa of the foregut. It occurs in all fish farming areas across the country, with Fujian, Guangdong, Guangxi, Hunan, Hubei and other places being the most serious. The mortality rate can be as high as over 90%. The fry are infected 12 days after being put into the pond, causing a large number of deaths. When the water temperature is 27-30℃, it takes 12-15 days for the worm to develop a generation in the body of grass carp. When the spores aged for 6-8 months are used to artificially infect grass carp fry, 100% of them will become ill. It mainly harms grass carp with a total length of less than 5 cm, and bighead carp, silver carp and black carp mixed in the same pond are not affected. The disease is prevalent from May to July, especially from May to June. Many small white cysts are formed at the parasitic sites of the pancake-shaped iodine bubble worm, and the cysts are surrounded by connective tissue membranes formed by the host. The body color of the sick fish is black; the fish is emaciated, with a slightly swollen abdomen, light red gills, anemia, no food in the intestines, thickened foregut, and degeneration and necrosis of the intestinal wall tissue; when a large number of pancake-shaped iodine bubble worms parasitize on the spine, the fish body may bend. According to reports from Sichuan Province, pancake-shaped iodine bubble worms parasitize in the muscles of carp fry, forming white cysts. The body surface of the sick fish is uneven, and the fish grows slowly. In severe cases, the disease causes a large number of deaths. 3. Wild carp iodine bubble worm disease Wild carp iodine bubble worms parasitize on the skin and gills of dace fry and summer carp, forming many gray-white tumor-like or dot-like cysts, especially on the body surface. In severe cases, it affects the breathing and swimming of the sick fish.

6. How to determine whether a cat is infected with hemolytic parasite?

Newborn cats are almost certain to have worms if they are listless, thin but have a big belly, and have worms in their buttocks. You can consider deworming them after they are 6 weeks old. My personal recommendation is to do so after they are two months old.

7. What are the epidemic characteristics of rabbit encephalitis protozoan disease?

The urine of sick rabbits contains rabbit encephalitis protozoa. The digestive tract is the main route of infection, and transplacental transmission is also possible. The disease is distributed all over the world and has also been reported in my country. The incidence rate is 15% to 76%.

8. How many times magnification of microscope is needed to observe fish parasitic protozoa?

At 4 times the magnification, you can see cat fleas, which is the lowest. You can see how big your parasites are. Ichthyophthirius spp. is relatively small, and some can only be seen with an oil lens after staining.

9. What is white skin disease in fish?

It's too easy! The first line of defense of fish is a layer of mucus on the outside of the body, which is used for non-specific immunity and resists external microorganisms. Once the integrity of this layer is destroyed, pathogens have a breakthrough. In epidemiology, many bacteria and fungi are infected and become ill due to trauma. For example, Saprolegnia, Trichoderma, Edwardsiella tarda, Aeromonas hydrophila, Pseudomonas aquaticus, Pseudomonas fluorescens, Pseudomonas albicans, Myxococcus ichthyophilus, etc. For example, Pseudomonas fluorescens, the pathogen of red skin disease, cannot invade the fish body if the fish body is intact and has no external trauma or parasites. However, it will invade when there is mechanical trauma or parasite bites that cause injuries.

10. What are the symptoms of fish printing disease?

Prevalence: The disease is a bacterial skin disease caused by Aeromonas punctata, characterized by skin rot and ulcers.

The pathogen is a conditional pathogen that will only infect the fish when it is damaged. It is common in summer and autumn.

Clinical symptoms: The lesions mainly occur on the trunk behind the dorsal fin and on both sides of the abdomen. The lesions appear as round or oval erythema, like a red seal on the fish body. The skin at the lesion site becomes congested, hemorrhagic and inflamed, forming ulcers, which are clearly demarcated from the surrounding normal tissues. In severe cases, bones or internal organs are exposed.

Treatment: Povidone iodine, spray the whole pond at a concentration of 0.15ml/m3 of water, mix with feed and take norfloxacin orally, 30mg/kg body weight, once a day for 3-5 days.
