Several city air borne contaminants have been alternately suspected to explain the increased prevalence of asthma in urban settings. More recently, cockroaches’ antigens had been targeted after a 1997 study conducted in the USA. Allergists now shed the light on the mice’s key role. This study shows that the mouse allergen, mainly found in its urine, rather than that of the cockroach, is more frequently associated with asthma attacks, impaired lung function, higher levels of FeNO in the region of Baltimore, Maryland. The mouse allergen is in fact a protein from the lipocalin family, which is similar to some involved in cat and dog allergy. Sanitary control over mice infestation is no small business! They reproduce 5 to 10 times per year, each time giving birth to 5 or 6 babies per litter. They can thread their way through 6 mm (1/4″) openings and wonder 3 to 9 m away from their nest. At AVANT GARDE Médical™, we have decided to include mouse allergen in our battery of screening tests for respiratory allergies (allergy test) with asthmatic patients!
