ENZYMATIC ACTION ON THE CAPSULAR MATERIAL PRODUCED BY PSEUDOMONAS AERUGINOSA OF CYSTIC FIBROSIS ORIGIN.

Doggett, Robert G. (Texas Institute for Rehabilitation and Research, Houston), Gunyon M. Harrison, Richard N. Stillwell, and Everett S. Wallis. Enzymatic action on the capsular material produced by Pseudomonas aeruginosa of cystic fibrosis origin. J. Bacteriol. 89:476-480. 1965.-An enzymatic study of the action of alpha- and beta-amylases on the slime envelope produced by Pseudomonas aeruginosa originating from patients with cystic fibrosis (CF) has been reported. It has been shown that these two enzymes in combination prevent the formation of the abnormal ethanol-benzene insoluble mucoid present in the slime layer of the above organism of CF origin. Evidence is also given which suggests that this organism can serve as a tool for studies of chemical abnormalities in the mucous metabolism of CF individuals.

COMPARISON OF SOME PROPERTIES OF PSEUDOMONAS AERUGINOSA ISOLATED FROM INFECTIONS IN PERSONS WITH AND WITHOUT CYSTIC FIBROSIS.

Doggett, Robert G. (Texas Institute for Rehabilitation and Research, Houston), Gunyon M. Garrison, and Everett S. Wallis. Comparison of some properties of Pseudomonas aeruginosa isolated from infections in persons with and without cystic fibrosis. J. Bacteriol. 87:427-431. 1964.-Pseudomonas aeruginosa, isolated from the respiratory tract of a group of patients diagnosed as having cystic fibrosis (CF) of the pancreas, attained the ability to produce in its capsule a material which was insoluble in certain organic solvents, such as ethanol. The capsule obtained from P. aeruginosa isolated from infected individuals who did not have CF was ethanol-soluble. This alcohol-insoluble mucoid from the CF P. aeruginosa could be demonstrated to persist after sequential subcultures of this organism. The relative viscosity and carbohydrate moiety of this insoluble mucoid fraction of P. aeruginosa from individuals with CF differed from that of the non-CF P. aeruginosa soluble mucoid fraction.
