Profuse fimbriae conferring O-inagglutinability to several strains of S. typhi-murium and S. enteritidis isolated from pasta products. Cultural, morphological, and serological experiments.
During the last 2 years several O-inagglutinable Salmonella strains were isolated from pasta products the typing of which presented great difficulties. Serological and morphological tests (by electron microscope) revealed a fimbrial antigen which was thermolabile to a certain degree. This antigen represents (in corroboration of J.P. Dugiud) a special type of fimbriae of Salmonella and is morphologically different from type 1 and typ3-2 fimbriae previously described. It is probably an abnormal mutant form of fimbriae. Morphologically characteristic are its very much finer structure of filaments (2,7 nm) (Type-1 and type-2 of fimbriae measure in the range 6-8 nm.) and the 2,7 nm) (Type-1 and type-2 of fimbriae measure in the range 6-8 nm.). and the 2,7 nm) (Tpe-1 and type-2 aof fimbriae measure in the range 6-8 nm.) and the 2,7 nm) (Tpe-1 and type-2 of fimbriae measure in the range 6-8 nm.) and the large number of filamentous appendages...
