title: Comparison between the erythrocyte and urinary Sda antigen distribution in a large number of individuals from Emilia-Romagna, a region of northern Italy.
abstract: In this study we found that the frequencies of Sda antigen on erythrocytes and urine of a large number of individuals from Emilia-Romagna (a region of northern Italy) are 0.89 and 0.93, respectively. The hypothesis that the infection by pyelonephritogenic Escherichia coli strains with specific adhesins for the alpha 2,3sialyl-galactosyl structure might operate as selective agents for the high frequency of Sda antigen in distal renal cells is discussed.
