title: [Microbiological study of 30 samples of heroin].
abstract: In the present study, 30 samples of heroin from material seized by the police in Vizcaya from 7-1-1987 to 6-30-1988 were investigated. Bacillus spp were isolated in 19 samples (63.3%), coagulase negative staphylococci in 14 (46.6%), Aspergillus in 3 (10%) and S. aureus in one (3.33%). In addition, chemical analysis of the purity of heroin was carried out with gas chromatography. The purity of the samples ranged from 1.1% to 94.3%. No relation was found between the weight of the sample, its purity and its degree of microbiological contamination. In the microbiological study of 4 lemons used to dissolve the drug, Candida krusei was isolated from three samples, Aspergillus in two and Geotrichum in one.
