Elimination of Pseudomonas aeruginosa from an Experimental Nude Mouse Colony

Abstract

In order to eliminate Pseudomonas (P.) aeruginosa from a contaminated nude mouse colony, the following procedures were carried out: improvement of environmental sanitation using an effective disinfectant against the organism; supply of tap water acidified with hydrochloric acid at pH2.5 -3.0; elimination of mice positive in isolation of P. aeruginosa from the nude mouse colony. The experimental results indicated that P. aeruginosa were successfully eliminated from the colony through a combination of the above three procedures.
