What is White Spot Disease? Do you have it back? And will it be contagious?

White spot disease is caused by the invasion of the protozoan melon worm into the fish** or gills. Its melon worm is a type of ciliate among the protozoa. Microscopic examination of the adult worm has a large horseshoe-shaped nucleus.

Juveniles have large nuclei that are round, oval, or rod-shaped. The body of the insect is soft and malleable, and the form is changeable. This disease is one of the most common diseases in ornamental fish, and its pathogenesis is characterized by rapid infection, wide epidemic and great harm.

**Method: Regardless of the drug used, first raise the water temperature to 30 degrees. The method of small melon insects not being resistant to high temperature can be used to promote the rapid maturity of the spores produced on the surface of the fish body, accelerate their growth rate, and make them fall off the surface of the fish body.

**Medications:1. It can also be soaked in 5 salt water for several days; 2。

or 2 parts per million (2ppm) of methyl blue solution, soaked for 6 hours a day; 3。Mixed with 0.05 parts per million (malachite green and 25 parts per million (25ppm) formaldehyde solution, the efficacy is better; 4。or soak in 28 30 parts per million (2ppm) of quinine hydrochloride solution for 3 5 days; 5。

or soak in two parts per million (2ppm) of mercurous nitrate for 30 minutes; 6。or soak in a red mercury solution of 50 to 70 parts per million (50 70 ppm) for 5 15 minutes, 2 times a day **After the white spots disappear, it is still necessary to use the drug for a period of time to kill the small melon worms that are not attached to the fish body.

It's contagious, go to the hospital and the doctor will tell you.

White spot wind is not contagious, it is a genetic disease. If a relative has one, then it is possible that the family has this defect in their genes. The probability of getting sick is higher.

Hello, the biggest feature of vitiligo is the spread of this disease, which is a refractory disease, and its causes are dozens of such as mental factors, autoimmunity, melanin self-destruction, etc., blindly** will cause the spread of vitiligo, and the condition is aggravated.

Vitiligo is not contagious.

Contagion is when a certain disease passes through a person.

to another person. Contagion is required.

There are three conditions: the source of infection, the route of transmission and the susceptibility to people.

Group, all three are indispensable. And white fatigue is common.

Depigmentation** disease, which is due to immune abnormalities

Oxidative stress and other reasons, resulting in local ** medium black.

Caused by the destruction or deletion of atrophic cells. Vitiligo.

Melanocytes in the lesions are reduced or disappear completely, leading to vitiligo patients' defense against ultraviolet light.

Reduced capacity. Therefore, vitiligo is not contagious.

sex, no need to worry.

First of all, although vitiligo is hereditary, it is not contagious, and vitiligo does not have patients with this infection.

Immediately after birth, a cribriform white patch appears in the anterior fontanelle, interlaced with black hair, the affected part of the hair is white, the eyebrows and eyelashes can also be white, and the size and shape of the white patches generally do not change with age.

The typical feature of the disease is frontal leukoplakia, 80% to 90% can be accompanied by white hair on the forehead, triangular or rhomboid, symmetrical, located in the frontal area** or slightly on one side, can be covered by the lower skin to the base of the nose, can also be seen in front of the chin, chest and abdomen, and upper limbs can see asymmetrical leukoplakia; Occasionally, there are white spots on the cheeks, and the hair at the lesions also turns white, a very small number of patients only have a handful of white hair on the occipital region, and there is no **white patch, which may be a variant of mottled disease, some patients have pigmentation spots on the dorsum of the hands and feet, diffuse white spots ** can be seen as island-like normal**, and the pigment around the vitiligo is thicker, and some people can be accompanied by unilateral iris pigment deficiency, fundus albino and macular dysplasia, strabismus and amblyopia, etc., some are accompanied by ataxia, deafness and intellectual disability, etc., no self-consciousness.

1. ** aspect

White spot disease is a widespread disease in the aquaculture industry. Its main ** are parasites, specifically filarial worms and flagellates chains. When these parasites enter the fish, they multiply under the epidermis or in the internal organs, forming many tiny white spots.

These small white spots will gradually increase and form clusters, which can affect the normal growth and health of the fish.

2. Environmental aspects

Water quality and the environment are also one of the causes of white spot disease. High or low water temperatures, excessive levels of oxygen and harmful substances in water bodies can accelerate the spread and spread of white spot disease. Therefore, for aquaculture farmers, maintaining a good water environment and timely monitoring of water quality indicators is an important guarantee for the prevention of white spot disease.

3. Feed

Unreasonable feed addition is also one of the causes of white spot disease. For example, too much or too little protein in the feed can lead to a decrease in the immunity of the fish body, which makes them susceptible to white spot disease. In addition, unreasonable additives or unclean feed can also lead to the appearance of white spot disease.

Therefore, it is necessary to carefully select the method of repurposing the feed and processed feed to ensure that the ingredients added to the feed meet the needs of the fish body and meet the standards.

4. Prevention and control

In the prevention and treatment of white spot disease, there are mainly the following measures. The first is to keep the water clean, clean up the sediment and replace the water source in time. The second is to disinfect the farm and keep the environment clean and hygienic.

In addition, the health care of the fish body is strengthened during the feeding process to enhance its ability to resist diseases. Finally, when the symptoms are found, the fish should be isolated in time**, and the appropriate drugs and methods should be selected**.
