章節(jié)摘錄

　　Most children，even the youngest of children，are delighted to be around cats and dogs．But these pets carry plenty of germs and allergens’，prompting researchers to ask：Are cats and dogs re ally safe for children?　　A study finds that，contrary to many parents’fears，owning cats or dogs does not increase a child’S risk of developing allergies，and in fact，may actually protect them．The study’s lead author，　　Dr．Dennis Own by of the Medical College of Georgia，says that even he was“very surprised by the results．Ownby and colleagues followed more than 470 children from birth to age 6 or 7 comparing those exposed to cats and dogs during their first year of life to those who were not．　　By using skin-prick tests for detecting common allergies，the researchers found that，contrary to what many doctors had been taught for years，children who had lived with a pet were not at greater risk．　　Even more remarkable，children who had two or more dogs or cats had an even greater reduce tion，up to 77 percent，in risk of allergies．Researchers suggest this protective effect may be the reosuh of early exposure to lots of bacteria that are carried by dogs and cats．Exposing young children to these bacteria helps“ exercise their immune systems early in life SO that theyre better able to resist allergic diseases later．　　“There’s something very important in that first year of life when the immune system is developing that we can retain it away from an allergic response，”said Dr．William Davis．　　And while researchers are not encouraging parents to buy dogs or cats just to reduce a childS allergy risk。they say if a family already has one or more animals，there’s no need to get rid of them．
