Get to know “Anthrax”, a bacillus anthracis bacteria that spreads from animals to humans.
Anthrax disease
What the locals call it, is called Kali disease. It is a disease known since ancient times. Anthrax is considered an important epidemic in the Animal Epidemics Act of 1956. It is a highly dangerous contagious disease that can occur in almost all grass-eating animals, including wild animals ยูฟ่าเบท such as elephants, barking deer, deer, and pets such as cattle. buffalo, goats, sheep and then infects people and other animals such as tigers, dogs, cats, pigs. The disease usually occurs in areas where there is a history of this disease spreading before.
But now because transportation is convenient and fast Animal traders often bring in sick animals. or animals that are in the incubation period of the disease to be sold in other localities This can cause the spread of the disease over far distances. This virus causes 3 types of disease in people: on the skin in the lungs from inhalation in the gastrointestinal tract and oro-pharynx from ingesting this infection
cause
This disease is caused by bacteria. The scientific name is Bacillus anthracis. It is an aerobic, non-motile, spore-forming rod (1-1.25 ? 3-5 nm) in the Bacillaceae family. When a sample of the patient is stained with Gram stain, square- large solitary ended gram-positive rods Or join together to form short chains. When in a dry place and the weather is not suitable, it will create spores covering the cell. It is very durable in both heat and cold. And disinfectants can exist in nature for decades.
Contact method
In most people, it is transmitt through the skin through contact with sick animals. or contact with animal products obtained from sick animals People with this disease are more common in those with agricultural occupations. In addition, these include Butchers, veterinarians, or people close to sick animals Diseases spread to people due to ignorance. or lack of caution Or maybe because of poverty. When an animal dies, the meat is cut up for consumption. However, the highest incidence of disease almost always occurs in animals first. Then people get infected.
- Cutaneous anthrax is caused by germs entering the skin around abrasions or cuts.
- Respiratory anthrax is caused by inhalation of spores attached to fur ship from the endemic area. Respiratory anthrax has not been reported in Thailand.
- Anthrax of the gastrointestinal tract and oropharyngeal. It is caused by eating meat that is sick and dies from this disease. and not cooked enough Most animals contract the disease from eating and breathing. The spores were obtained in pastures. Where animals had died from the disease before, but in the early days of the outbreak. (Late summer to the beginning of the rainy season) Animals contract the disease from eating and from breathing at the same time. This occurs when animals graze on grass and they pull up the roots that are stuck to the ground. Anthrax spores that stick to grass blades and in the soil enter through the mouth and fly away in dust. While pulling the grass, the spores enter the nose through inhalation.
