Anthrax is an animal infectious disease, and there are few cases of human infection. In the 20th century, only 18 cases of inhaled anthrax were found in the United States. Recently, Texas reported a case of cutaneous anthrax, and North Dakota also reported a case. Among the anthrax cases infected by human beings, 95% belong to skin anthrax caused by contact with animals or animal tissues. Eating contaminated meat can also cause anthrax, but the centers for disease control and prevention in the United States have not received reports of digestive anthrax.

pathogen

Anthrax spores are an inert form of anthrax bacteria. Just like seeds, they can only grow in the right environment. If spores are inhaled by people, larger spores will remain in the upper respiratory tract, which is less fatal. Spores with a diameter of 1 to 5 microns (1 micron is one thousandth of a millimeter) can penetrate the alveoli of the lungs, and the immune system will react after discovering the spore invasion, killing some spores and bringing the remaining spores into the pulmonary lymph nodes. Then spores grow in lymph nodes, and within 1 to 60 days, anthrax bacteria begin to multiply, infecting other tissues in the chest, leading to the onset of the disease.

Anthrax is a malignant infectious disease of people and animals. Humans will be infected if they touch or eat the meat of sick animals and inhale a lot of dust carrying anthrax bacteria. Its main symptoms are skin ulcer, edema and even necrosis, high fever, bleeding, chest, neck or abdominal swelling.

It can make the victim suffocate, sweat profusely, and go into shock within 36 hours until death. Its spores can survive in soil for 40 years and are extremely difficult to eradicate. It can only be killed by steam disinfection or incineration.

Anthrax is also a common bacteria in war, which has caused countless deaths.

Clinicopathological manifestations

Anthrax is a malignant infectious disease of people and animals. Humans will be infected if they touch or eat the meat of sick animals and inhale a lot of dust carrying anthrax bacteria. After anthrax bacteria infect the tissue in the chest cavity, the bacteria will also produce toxins that can enter the blood vessels, which will lead to pulmonary bleeding, stagnant water and tissue decay. Its main symptoms are skin ulcer, edema and even necrosis, high fever, bleeding, chest, neck or abdomen swelling, pneumonia and so on. The incubation period of this disease is about 7 days, but it takes up to 60 days for the disease to develop completely.

treat cordially

People infected with anthrax must be treated before symptoms appear, otherwise the disease will be fatal. The treatment is to use antibiotics. However, American scientists point out that antibiotics can only kill some anthrax spores in human tissues, but they can't resist the toxins produced by spores in the body, which is why antibiotics are difficult to deal with anthrax. Moreover, antibiotics only fight bacteria in the early stage of the disease, but they are unable to resist a large number of toxins produced by bacteria. According to the latest data, the sales of Cipro in new york, USA have greatly increased because more and more people are worried that terrorists will use biological weapons to carry out terrorist attacks. Cipro, mainly produced by European Connecticut pharmaceutical factory, is the only oral drug recommended by the US Centers for Disease Control and Prevention to treat anthrax. Other antibiotics used to treat anthrax include doxycycline and penicillin, and gentamicin, erythromycin and chloramphenicol can also be used.
