Various Escherichia coli strains differ in the composition of their major outer membrane proteins. However, all E. coli K12 strains tested possess the same major outer membrane proteins a, b, c and d, although quantitative differences were detected.

Two mutants of a pneumococcus type I with diminished peroxide production were selected from a population of nitrosoguanidine-treated cells. White cells of normal patients killed the mutant pneumococci as well as the otherwise isogenic wild-type strai

The genetic behavior in transformation reactions of 20 noncapsulated mutants of pneumococcus type III suggests that each has a single-site mutation in the locus controlling the synthesis of uridine diphosphate glucose (UDPG) dehydrogenase. Each strai

Capsulated mutants of pneumococcus producing a capsule of soluble polysaccharide related immunologically to the C or cell wall polysaccharide of pneumococcus have been isolated from several noncapsulated variants of this organism. The capsular materi

A method is described for estimating quantitatively the frequency of transformation of pneumococci to new capsular types. It is found that, when S- III cells are exposed to deoxyribonucleic acid (DNA) from wild-type I strains, transformation to SI oc

SUMMARY: Disruption of cells in a Mickle disintegrator in the presence of n-octanol is described as a method for obtaining extracts from the non-capsulated strain R19 of Streptococcus pneumoniae, derived from a strain of capsular type II. Such extrac

Pneumococci manifesting binary capsulation have been produced through the agency of transformation reactions. Such cells produce two capsular polysaccharides which are closely similar if not identical with those produced by corresponding singly capsu
