Abstract
This study include the detection of fimbriae by Transmission electron microscope in three type of locall isolates of Salmonella (S.typhi , S.typhimurium, S.montevideo) and compared with their standard strains (S.typhi , S.paratyphi B , S. paratyphi C ) respectively. The results showed that all isolates of Salmonella possessed type 1 fimbriae .
The study also determind the ability of these microorganism to adhered to Rat enterocyte , the statistical analysis reveled that there was no significant differences in adhesion rates to Rat enterocyte between locall isolates and their standard strains
