Distribution, clearance, and mortality of environmental pseudomonads in mice upon intranasal exposure.


When introduced intranasally, P. cepacia AC1100 (approximately 10(8) CFU/animal) and P. aeruginosa AC869 (approximately 10(3) CFU/animal) were readily cleared from the mouse. However, a approximately 10(7)-CFU dose of AC869 persisted for 14 days. Strain AC869 had a 50% lethal dose of 2.7 x 10(7) CFU. Slight morbidity occurred in animals treated with… (More)
