When was the last time BSE was seen?

BSE is a subacute progressive neurological disease caused by prions, usually vacuoles appear in brain cell tissues, astrocyte hyperplasia, amyloid protein fibers are found in brain anatomy, and are accompanied by systemic symptoms, characterized by long incubation period, high mortality and strong infectivity. Since the disease was first discovered in the United Kingdom in 1985, it has gradually spread around the world, posing a huge threat to the cattle industry, the catering industry and human life. As of 2004, there were 179,000 confirmed sick cattle in the UK alone, involving 35,181 farms, slaughtering and burning more than 11 million sick cattle, and causing tens of billions of pounds in economic losses.

Over the past 20 years, BSE has spread to 31 countries in Europe, the Americas and Asia, and more than 100 countries have been implicated in BSE, causing huge economic losses and social panic. [1]

Introduction to BSE.

BSE is a subacute progressive neurological disease that occurs mainly in adult dairy cows, characterized by a long incubation period, gradual exacerbation of the disease, degeneration of the central nervous system, and eventual death. BSE was first discovered in the United Kingdom in 1985 and then spread to Europe and many countries and regions around the world, causing huge losses to the cattle industry around the world and affecting industries related to cattle-derived materials. In particular, with the epidemic of mad cow disease, the emergence of a new type of Chuizkob disease (commonly known as human mad cow disease) caused by the same ** child has led to a worldwide panic about mad cow disease, which has a global impact on animal and human health and international political economy.

Symptom. BSE can present with neurological and systemic symptoms, which often precede the onset of systemic symptoms. Common neurological symptoms include behavioral abnormalities, ataxia, and hyperesthesia.

Behavioral abnormalities are mainly manifested by solitude, anxiety, fear, furiousness or depression, confusion, involuntary movements (such as teeth grinding, muscle twitching, tremors, and spasms), reluctance to pass through concrete floors, turns, entering the corral, crossing the door, or expressing milk. Sick animals often exhibit aggressive behavior when approached or pursued, which is also an important reason for its common name mad cow disease. [1]

The ataxia of BSE is characterized by instability of movement of the hind limbs, especially in sharp turns. The affected cattle have abnormal gait when walking fast, and the front and rear limbs on the same side start at the same time, and then develop into shaking hindquarters, short stride, difficult turning, easy to fall, and even difficulty in standing up or unable to stand and lie on the ground all day long. Hyperesthesia is often manifested as excessive sensitivity to touch, light and sound, when touching the neck and ribs of the cow with a hand or with a blunt object, the sick cow will be extremely nervous and trembling, and the hind limbs will be touched with a broom, and there will also be a nervous kicking reaction, the sick cow.

When I looked at the Portuguese flag he was wearing, I felt that he would definitely not stay.

Summary. Brazilian BSE is an infectious disease caused by a virus, which is thought to have started circulating a few years ago. BSE in Brazil is caused by a virus called Klee Scarininen, among others.

This complex virus can cause disease in cattle and sheep, and like other infectious diseases, it cannot have a real end time, so to speak, as long as there are animals and the environment, it can continue. Therefore, the most effective way to eliminate BSE in Brazil is to implement a series of preventive measures to control its spread and to take measures to reduce the population of its potential pathogens.

It's not over at the moment.

How long does it take to finish?

Mad cow disease. "mad cow"BSE was first thought to be a new neurological disease in cattle in 1984-1985. At that time, cattle were found on farms in the United Kingdom to be suffering from this neurological disease and were contagious. When veterinary experts at the National Veterinary Centre Laboratory in Victoria Bridge in the United Kingdom performed an autopsy on the brain of a sick cow, they found that the brain tissue of the sick cow was spongy degenerated.

According to the pathological changes, in November 1986 this disease of the nervous system was named bovine spongiform encephalopathy.

The average incubation period of BSE is 4 to 6 years, once the disease occurs, the sick cattle are acutely or chronically progressive dysfunctional, the initial appetite and body temperature are close to normal, with the intensification of progressive lesions of the central nervous system, presenting typical neurological symptoms, followed by systemic symptoms. Common neurological symptoms are behavioral abnormalities, ataxia, and paresthesias. It is believed that if a sick cow exhibits the above three symptoms at the same time and the symptoms are more than 1 month, the former annihilation can be considered to be the cow's BSE.

Behavioral abnormalities are mainly manifested as solitude, anxiety, fear, irritability or depression, confusion, involuntary movements (such as teeth grinding, muscle twitching, tremor and spasms), reluctance to pass through concrete floors, turning, entering the corral, crossing the door or expressing milk, etc.

Summary. Bovine BSE (BSE) is a terrible neurological disorder in which the central nervous system is gradually damaged after an infection in cattle, resulting in abnormal behaviors such as irritability, convulsions, stiffness, loss of balance, inability to stand, and eventually death. Once BSE is diagnosed, most affected cattle do not survive for more than half a year, with the shortest being a few months.

Since BSE can be transmitted to humans through the consumption of meat or the ingestion of blood from affected cows, BSE is a very dangerous disease that should be taken seriously.

Summary. BSE is a common bovine disease that is caused by a virus and can be transmitted through contact infection. Symptoms of BSE include fever, convulsions, dizziness, muscle cramps, diarrhea, vomiting, liver damage, etc.

The main method of mad cow disease is antiviral drugs, which can control the disease and increase the rate if detected early and timely. However, if the condition is severe,** the effect is not good, the condition may last for a long time and may even lead to death. Therefore, it is necessary to detect mad cow disease as soon as possible and take effective measures in time to reduce the development of the disease, increase the rate and save the lives of cattle.

Can you elaborate on that a little bit more?

BSE is a contagious disease that causes cattle to become irritable, aggressive, and even dead. BSE occurs due to exposure to the virus in cattle, which can be spread through the air or infected through contact. BSE usually lasts for a few weeks, but sometimes it lasts for months or even years.

To prevent BSE, the most important thing is to keep the cattle healthy, especially to provide them with a good diet and environment. In addition, the health of the cattle should be checked regularly, and if symptoms of mad cow Shenxiao disease are found, measures should be taken in time**. Personal Tips:

Pay attention to the health status of cattle, check regularly, and take timely measures** to prevent the occurrence of mad cow disease.

Mad cow disease, also known as bovine brain spongiform disease, was named BSE in November of the abbreviated year, and was first reported in the British press.
