Dogs Reduce Asthma Risk In Kids UCSF and the University of Michigan have released new research that indicates dust from houses where dogs are present may provide protection from respiratory syncytial virus –which is also called RSV. If your child has had RSV they may be at a higher risk of developing childhood asthma. This statement caught my attention because my first child had RSV when he was three months old and was in the hospital for over a week. In their study, they found that when they fed mice house dust from homes that had dogs in them, the mice were protected against RSV. Some of their research has also shown that owning a pet protects children from developing asthma. They performed tests on three groups of mice. Group #1 was exposed to house dust collected from homes that had a dog for a pet. The other two groups were not exposed to the house dust. Next, group #1 and group #2 were exposed to RSV. Group #3 was not exposed to the RSV. Group #1 which was the group that had been exposed to the house dust did not show any of the symptoms associated with RSV after being exposed to the virus. Such symptoms would include airway inflammation and/or the production of mucus. Group #2 which was exposed to the virus but not the house dust did show symptoms of RSV. Group # 3 which was the control group, was not exposed to the house dust or the virus and as predicted, did not show symptoms of either. It was concluded that the microbes within the dust from the dogs might colonize the stomach and provide some immunity or protection to the host against the virus. If you own a dog and you have children, you might want to shake those carpets, fluff the pillows, stir up that dog dander and have your child take some deep breaths! Who knows, it may help protect them from developing childhood asthma! Sources: MORNINGGOSSIP.com The Augusta Chronicle You Might Also Enjoy : Filed under: Dog News Like this post?

Prevela i uredila: Irena Dujmušić Matrix World Čini se da kućna prašina iz domova s psima štiti od infekcija s respiratornim virusom koji je povezan s prehladom i razvojem astme kod djece. Istraživači sa Kalifornijskog Sveučilišta u San Franciscu predstavili su svoja otkrića ove godine na Glavnoj skupštini Američkog društva za mikrobiologiju. “U ovoj studiji smo utvrdili da kućna prašina iz domova u kojima su prisutni psi, štiti miševe koji su njome hranjeni od dječjeg dišnog zaraznog agensa – respiracijskog sincicijskog virusa (RSV). RSV infekcija je česta kod dojenčadi i može se manifestirati u vidu blagih do teških respiratornih simptoma. Teška infekcija u djetinjstvu povezana je s povećanim rizikom od razvoja astme u djetinjstvu “, izjavljuje Kei Fujimura, istraživač na studiji. Fujimura i njezini kolege usporedili su tri skupine životinja: miševe hranjene kućnom prašinom iz domova s psima prije nego su bili izloženi infekciji RSV-a, miševe zaražene s RSV-om bez izloženosti prašini i kontrolne skupine miševa koji nisu zaraženi RSV-om. “Miševi hranjeni prašinom nisu pokazivali simptome povezane s RSV-infekcijom dišnih putova, kao što su upala i proizvodnja sluzi. Oni također posjeduju različit probavni bakterijski sastav u odnosu na životinje koje nisu hranjene prašinom “, navodi Fujimura. Posjedovanje ljubimaca, posebno pasa, već je povezano sa zaštitom protiv razvoja dječje astme, izjavljuje Fujimura. Nedavno su ona i njezini kolege pokazali da se zbirka bakterijskih zajednica (mikrobiomi) iz kućne prašine iz domova koji posjeduju mačku ili psa kompozicijski razlikuje od kućne prašine iz domova bez kućnih ljubimaca. “To je rezultiralo nagađanjem da mikrobi povezani s kućnom prašinom iz domova s psima mogu kolonizirati probavni trakt, modulirati imunološki odgovor i zaštititi domaćina protiv patogena astmageničkog RSV-a”, navodi Fujimura. “Ova studija predstavlja prvi korak prema utvrđivanju identiteta mikrobnih vrsta koje daju zaštitu protiv ovog respiratornog patogena.” Identifikacija specifičnih vrsta i mehanizama na kojima se temelji ovaj zaštitni učinak predstavlja ključni korak prema razumijevanju značajne uloge mikroba u definiranju ishoda alergijskih bolesti te može dovesti do razvoja terapija na bazi mikroorganizama kako bi se zaštitili protiv RSV-a i u konačnici smanjili rizik od razvoja astme , izjavljuje Fujimura.
