"These microbes can become a protective barrier for children from such diseases as asthma. This conclusion was made by experts from the University of California under the direction of Dr. Kay Fujimori. According to scientists, bacteria that live on animals, serve as a kind of barrier for respiratory syncytial virus, which increases the risk of asthma, reported ABC News.
Indeed, the bacterial community composition in homes with Pets and without them have a significant difference from each other. And if in the house there lives a dog, the child in the future is unlikely to develop asthma. In order to properly understand this question, scientists have collected samples of dust taken in different houses, and then along with the food fed samples of mice.
After eight days in the animal organism was introduced respiratory syncytial virus, with simultaneous monitoring of their immune response. So, those mice that received the samples taken in homes where dwelt the dog does not show signs of inflammation or mucus production-secret. Plus, in the gastrointestinal tract of mice were found community of bacteria, which radically differed from the control group.

It microflora in the intestine and is protected from the virus. It is quite possible, if at a young age to have an impact on the body, in relation to diseases like asthma will develop immunity. To confirm this, the need for additional research.
