很多中老年人退休后,喜欢养鸟为乐,以此休闲安度晚年。但是,中老年人养鸟时也应注意自身防病。动物学家研究发现,在很多种鸟的身上有一种叫做“鹦鹉热”的病原体。这种病原体不但使鸟类本身发病,而且在病鸟排泄物里也带有病原体,还可使经常接触鸟的养鸟者患“养鸟病”。 After retirement, many middle-aged and elderly people like to keep their birds for pleasure, so that they can spend their leisure time in their later years. However, middle-aged and elderly birds should also pay attention to their own disease prevention. Zoologists have found that on many species of birds there is a pathogen known as “parrot fever.” This kind of pathogen not only causes the bird itself but also brings the pathogen in the excrement of diseased birds. It can also make the bird-bearers who frequently contact the birds suffer from “bird disease.”
