Název v původním jazyce

The Influence of Environmental Temperature and Humidity on Temporal Decomposition of Cockroach Allergens Bla g 1 and Bla g 2 in Feces

Popis výsledku v původním jazyce

The infuence of environmental temperature (15, 20, 25, 30, and 35°C) and moisture (53, 75, 85, and 100% RH) on allergen degradation was estimated for 3, 6, and 9 mo. Bla g 1 was more stable than Bla g 2 and the proteins. The proteins and Bla g 2 contentswere correlated negatively with the decomposition time; Bla g 1 was not. However, when the content of Bla g 1 in control and exposed tubes was compared, the decrease after exposure was signi?cant at exposure in 35°C, 53 and 100% RH. In laboratory, the shortest half-life (16-38 d) of Bla g 2 was at high temperature and humidity (100% RH at 35°C), whereas the longest half-life (340 d) was at 25°C and 85% RH. In the apartment, the half-life was 406 d. The results indicate that Bla g 1 and Bla g 2 allergens can persist in feces for several months under usual household humidity and temperature.
