Profuse fimbriae conferring O-inagglutinability to several strains of S. typhi-murium and S. enteritidis isolated from pasta products. Cultural, morphological, and serological experiments.

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