Abstract:
Selected number of urinary E. coli isolates from patients were subjected to the tests to characterize in vitro properties, compared with the strains of normal flora in intestinal tract or other sources. Further studies were carried out for determination of the mechanism of pathogenesis by using rabbit as an experimental animal model. Both strains of 87E1 and 87E51 which had one type of pili, were eliminated rapidly 4 or 8 days after inoculation into renal pelvis of rabbit. On the contrary, 88E18 strain which had both types of pili successfully colonized in urinary tract and the rabbit died due to urosepsis after the 8th day of experiment. The result of bacterial count colonized in the tissue by colony forming unit (CFU)per gram were similar to those in the urine.
