Study on crop adhesion genetic determinant in Lactobacillus reuteri

The genetic determinant responsible for adherence in one strain of Lactobacillus reuteri isolated from chicken crop has been investigated. After curing experiments carried out on this strain, a plasmid-free derivative was obtained, resulting unchanged as regards adhesion ability and carbohydrate fermentation pattern, but showing a loss of antibiotic resistances. It is suggested a possible localization on chromosome of adhesion determinant.
