Urinary tract infection due to a mucoid (M) form of Salmonella. A "new" transformation from M form into T1 form.
An eighty-year-old patient suffering from prostatic hypertrophy developed cystitis associated with fever, macrohematuria and significant bacteriuria. In urine cultures, growth of a mucoid (M) form of Salmonella was seen which changed into a T1 form after having been stored at room temperature or passed through U tubes. While the M form did not agglutinate in Salmonella O and H antisera, H antigens of the T1 form could be identified as l,v and 1.7. The isolate was therefore designated S.I M----T1:l,v:1.7. To date, no such M-T1 variation has been described. For diagnostic and epidemiologic purposes Salmonella M forms should be transformed into the N form or a T form (as in our case), because it is possible to demonstrate O or T and H antigens in these forms. The method of transformation and the pathogenesis of urinary excretion of salmonellae are briefly described.
