AIMS To evaluate the effectiveness of two spray-based decontamination methods for surface contamination reduction and to determine the potential for contamination spread by these methods. METHODS AND RESULTS Material coupons (treated plywood and concrete) were contaminated with c. 1 × 10(7) spores of Bacillus atrophaeus by aerosol deposition. Decontaminants (pH-adjusted bleach or Spor-Klenz(®...

Most data dealing with the biopreservative activity of lactic acid bacteria (LAB) are focused on their antibacterial effects. Food spoilage by mould and the occurrence of their mycotoxins constitute a potential health hazard. Development of biological control should help improve the safety of products by controlling mycotoxin contamination. Data have actually shown that many LAB can inhibit mou...

It is well known that the bioavailability of artifical radionuclides such as Sr, Cs and Pu in contaminated soils depends on the source term origin of the contamination. Altough the behaviour of the mentioned radionuclides in the soil is also influenced by the time passed from the contamination event and the characteristics of the contamination receiving soils. The objective of the present work ...

background and objectives: contamination of cell lines and biological products is one of the major problems of cell culture techniques. rapid detection of mycoplasma contamination in cell culture is an important part of quality control standards in related laboratories. the aim of this study was to evaluate the efficacy of pcr in detection of myroplasma as contaminants in cell cultures and othe...

Environmental contamination has become a serious problem to human and environmental health, as exposure to a wide range of possible contaminants continuously increases due to industrial and agricultural activities. Whole cell sensors have been proposed as a powerful tool to detect class-specific toxicants based upon their biological activity and bioavailability. We demonstrated a robust toxican...

A quantitative TaqMn Real-Time PCR assay was developed and its diagnostic value on human serum and livestock samples were evaluated. Brucella species could be distributed through communities as a biological agent. Rapid detection of biological threat agents is critical for timely therapeutic administration. Quantitative real-time PCR provides a rapid, sensitive and specific tool for molecular i...
