鼠疫杆菌画漫画的英文
鼠疫杆菌（Yersinia pestis）属于耶尔森氏菌属(Yersina)。它是引起烈性传染病鼠疫(Plague)的病原菌。

veral countries in the past. Aerosol dismination of bacteria would cau primary pneumonic plague in the expod population, an otherwi uncommon, highly lethal, and contagious form of plague.
中国的桥鼠疫杆菌为短小的革兰氏阴性球杆菌，新分离株以美兰或姬姆萨染色，显示两端浓染，有荚膜（或称封套）。在病灶标本中及初代培养时，呈卵圆形。在液体培养基中生长呈短链排列。需氧及兼性厌氧菌，最适温度为27-28℃，初次分离需在培养基中加入动物血液，亚硫酸钠等以促进生长，在血平板上，28℃培养48小时后，长成不透明的，中央隆起，不溶血，边缘呈花边样菌落，这种菌落形态为本菌的特征。在液体培养基中24小时孵育逐渐形成絮状沉淀，48小时在液表面形成薄菌膜，从菌膜向管底生长出垂状菌丝，呈钟乳石状。
鼠疫杆菌对外界抵抗力较强，在寒冷、潮湿的条件下不易死亡，在-30℃仍能存活，于5-10℃条件下尚能生存。可耐日光直射1-4小时，在干燥咯痰和蚤粪中存活数周，在冻尸中能存活4-5个月，但对一般
消毒剂、杀菌剂的抵抗力不强。对链霉素、卡那霉素及四环素敏感。
Plague as a Biological Weapon
Plague is currently considered to be one of the most rious bioterrorism
threats. Y. pestis was developed as an aerosol weapon by veral countries in the past. Aerosol dismination of bacteria would cau primary pneumonic plague in the expod population, an otherwi uncommon, highly lethal, and contagious form of plague.
A number of factors contribute to concern over the u of plague as a biological weapon:
There is widespread availability of Y. pestis in microbe banks around the world.
There is widespread natural availability of the Y. pestis bacteria in endemic areas
国际日Reports indicate that techniques for mass production and aerosol dismination of Y. pestis have been developed.
The fatality rate of pneumonic plague in untreated cas is extremely high.
Plague has the potential for condary spread from person to person following an attack.
Y. pestis can be disminated in aerosol form.
Plague has a low infectious do.
Antibiotic resistant strains of Y. pestis exist in nature.
A 1970 World Health Organization (WHO) asssment asrted that in a worst-ca scenario a dismination of 50 kg of Y. pestis in an aerosol cloud over a city of 5 million might result in 150,000 cas of pneumonic plague. Of tho, 80,000 to 100,000 cas would require hospitalization, and 36,000 victims would be expected to die. (See "The History of Bioterrorism: Plague," a short video from the
CDC.)
鼠疫
黑死病（鼠疫耶尔森菌引起的传染病）一般指鼠疫（人类因感染鼠疫耶尔森菌引起的传染病）。
鼠疫是鼠疫杆菌借鼠蚤传播为主的烈性传染病，系广泛流行于野生啮齿动物间的一种自然疫源性疾病。临床上表现为发热、严重毒血症症状、淋巴结肿大、肺炎、出血倾向等。鼠疫在世界历史上曾有多次大流行，死者以千万计，我国在解放前也曾发生多次流行，病死率极高。
病因
1.鼠蚤叮咬
经鼠蚤传播，鼠蚤叮咬是主要的传播途径，啮齿动物→蚤→人的传播是腺鼠疫的主要传播方式。
2.呼吸道感染
经呼吸道飞沫传播，通过呼吸、谈话、咳嗽等，借飞沫形成“人→人”的方式传播，并可造成人间鼠疫的大流行。
3.皮肤感染
经皮肤传播，剥食患病啮齿动物的皮、肉或直接接触患者的脓血或痰，经皮肤伤口而感染。
4.消化道感染病毒感染和细菌感染的区别

韬略Signs and Symptoms
Diagnosis of plague is bad on clinical prentation of symptoms and confirmed by laboratory testing, which usually takes 24 to 48 hours. There are no widely available rapid diagnostic tests for plague. The first sign of a bioterrorist attack with plague would most likely be a sudden surge of patients prenting at hospitals and doctors' offices with symptoms of vere pneumonia and psis.
