“…Table 2 shows the 19 different types identified among 139 Proteus mirabilis or vulgaris investigated, according to Dienes-effect. Nine types affected various patients (2)(3)(4), while the others affected one patient only. It can be noted that half of the 27 patients suffered from infection or contamination by only one type of Proteus, and 13, by more than one type.…”

“…are the microorganisms most commonly isolated from the urinary tracts of patients in our Paraplegic Unit during systematic controls for infection or contamination (3). Primarily because of the special characteristics of spinal cord injury patients, such as prolonged hospitalization and urethral catheterization, these organisms are easily transmitted in such a unit and were, in fact, responsible for several crossinfection outbreaks between 1982 and 1983.…”

The authors study the Dienes effect in 136 P.mirabilis and 2 P.vulgaris strains, isolated from different infection or colonization sites, in 27 spinal cord injured patients, admitted to a Paraplegic Unit, during a 9 month period. It is shown that 7 cross-infection and 18 cross-contamination episodes occurred, affecting 13 of 27 patients, which indicates the great spreading capacity of these microorganisms; 97% of the results obtained were observed once again after 6 months' storage of strains. In addition, in 7 of these strains their resistance to several antibiotics was cured by treating them with acriflavine salts, demonstrating that the Dienes effect persists even when resistance to antibiotics is modified; the authors conclude that the Dienes effect is an accurate stable epidemiological tool to identify cross-infections and its origins, and to facilitate the interruption of the chain of infection.
