时下,有许多家庭饲养狗、猫、鸟等宠物,这些惹人喜爱的小动物给人的生活带来了不少乐趣。但是它给人类带来的弊端却地不容忽视。这类弊端主要指动物身上携带的各种病菌,传染给它们的主人后,使人得病,这种病,在医学上被称为“人畜共患病”。到目前为止,世界上已被证实的“人畜共患病”约有200多种,其中比较严重的有89种,在许多国家和地区广泛流行的主要有鼠疫、狂犬病、血吸虫病等34种。这些疾病大部分发生在经济不发达的发展中国家。 Nowadays, there are many families feeding dogs, cats, birds and other pets, which bring a lot of fun to people’s lives. However, the disadvantages it brings to mankind can not be ignored. This kind of malpractice mainly refers to the various bacteria carried on the animals, which are infected after they are transmitted to their masters. The disease is medically called “zoonosis”. So far, there have been about 200 kinds of “zoonosis” confirmed in the world, of which 89 are more serious. There are 34 species of plague, rabies and schistosomiasis widely prevailing in many countries and regions. Most of these diseases occur in economically underdeveloped developing countries.
