Abstract

The potential role of microbial agents was investigated in 13 cases of Sudden Infant Death Syndrome and in 9 non-SIDS cases in Budapest between September 1996 and May 1998. Autopsy, histological examination and microbiological tests were performed on samples of blood, cerebrospinal fluid, pharyngeal samples and lung tissue infants under one year died suddenly, without previous diseases. The multifactorial pathomechanism of SIDS was suggested by the isolation of toxin producing Staphylococcus aureus-, Enterobacteriaceae and Candida albicans strains in large number and by the detection of Parainfluenza Type 2 virus antigen. S. aureus proved the predominant bacteria in the SIDS cases. Nasopharyngeal microbial flora and S. aureus carrier of 100 age matched healthy infants were tested during the same period. S. aureus was isolated from 54% of SIDS cases and 37% from healthy infants /OR=1.986 (95% Confidence interval=0.55-7.33), p=0243/. The enterotoxin and TSST-1 toxin producing activity of S. aureus showed the characteristic difference. The toxigenic S. aureus was detected in 46% of SIDS cases and 16% of healthy infants /OR=4.5 (95% CI=1.15-17.72), p=0.010/. The distribution of toxigenic and nontoxigenic isolates was 86% in SIDS cases and 43% in healthy infants /OR=7.875 (CI=0.78-191.89), p=0.041/.
