title: [Antimicrobial activity of paraformaldehyde tablets reproducing their use conditions in Brazilian health institutions].
abstract: The sterilizing activity of Parafolmaldehyde Tablets reproducing the conditions of use in the Brazilian health Institutions (without the heating, without increment of the relative humidity, in 0.5%, even for a long period of exhibition of 12 hours) was evaluated "in vitro" by microbiologic monitoring, according to the methodology of the AOAC, officially adopted by the Brazilian Health Ministry for registration of that category of products. The results of the experiments refuted the sterilizing action of Parafolmaldehyde Tablets in this conditions. Thus, it was evaluated the disinfectant action of the product using the vegetative bacteria by Use Dilution Method, preconized for AOAC and adapted for gaseous products, against the tests microorganisms standardized Staphylococcus aureus (ATCCn. 6538), Samonella choleraesuis (ATCCn. 10708) and Pseudomonas aeruginosa (ATCC n. 15442). In these experiments, the results of the cultures showed 100% negative against all the tested bacteria inferring indications of disinfectant activity of high level action.
