Relationship between human blood group antigens and haemagglutination, adhesion properties of some urinary tract infection (UTI) bacteria


For this study a total of 135 healthy person (71 female, 64 male) were eligible. Their urine samples were assayed for adhesion test, and from 94 persons of them blood samples were taken for agglutination assay. Data from the results indicated that agglutination properties was found in E. coli and Proteus with (A+, B+, AB+, AB-, O+, O- ) human erythrocytes. While Klebseilla and Pseudomonas were able to agglutinate few types of human erythrocytes. The adhesion mean of bacteria were increased significantly with age increasing. No significant differences were appeared between the types of bacteria used in the assay. Significant variation was noted between the bacterial adhesion mean to cells with six, the adhesion mean was apparently more in females than of males. The bacteria were adhered significantly more to uroepithelial cells obtained from positive blood group antigen persons, the highest rate was for AB+, A+ blood groups and the lowest was for B- in both sexes for all types of bacteria used.
