BACKGROUND The aim of the present systematic review and meta-analysis was to assess the efficacy of antimicrobial photodynamic therapy (aPDT) as a therapeutic protocol for oral decontamination. METHODS In order to address the focused question: Is aPDT a useful therapeutic protocol for oral decontamination?, an electronic search without time or language restrictions was conducted up to July 20...

Reusing filtering facepiece respirators (FFRs) has been suggested as a strategy to conserve available supplies for home and healthcare environments during an influenza pandemic. For reuse to be possible, used FFRs must be decontaminated before redonning to reduce the risk of virus transmission; however, there are no approved methods for FFR decontamination. An effective method must reduce the m...

We investigated the presence of antibiotics in cryopreserved cardiovascular tissues and cryopreservation media, after tissue decontamination with antibiotic cocktails, and the impact of antibiotic residues on standard tissue bank microbiological analyses. Sixteen cardiovascular tissues were decontaminated with bank-prepared cocktails and cryopreserved by two different tissue banks according to ...

Strict planetary protection practices are implemented during spacecraft assembly to prevent inadvertent transfer of earth microorganisms to other planetary bodies. Therefore, spacecraft are assembled in cleanrooms, which undergo strict cleaning and decontamination procedures to reduce total microbial bioburden. We wanted to evaluate if these practices selectively favor survival and growth of ha...

Cumin seeds may have been exposed to a high level of bacterial contamination and presence of pathogenic organisms could potentially create a public health risk. Apart from the public health, heavy microbial contamination is also a crucial problem in exportation. Most microorganisms contaminating the cumin seeds reside on the surface, and generally inner parts of the seeds are free from the micr...

Spices and aromatic herbs are widely used in different food branches and recently, industrialists from the agro-food field have started paying attention to the microbiological quality of these products. Microbial contaminants susceptible to be present at the surface of spices can potentially induce various pathologies in humans. The most frequent are bacterial or viral gastroenteritis. Today, t...

INTRODUCTION During hygienic-microbiological monitoring of the water quality in dental units, the total bacterial colony count was found to exceed the limits for drinking water quality; in addition, mold contamination was detected. The presumed cause was irregular decontamination of the units through purging and intensive decontamination. METHODS To decontaminate the units, the manufacturer's...

This work was aimed at identifying microbials and determining the biokinetic parameters for bio-decontamination of oilfield produced water. An extant physical treatment unit water re-engineered retrofit with a discontinuous aerobic bioreactor (Bio-Unit) system. The Bio-Unit operated in fill-and-draw sequence rates total organic carbon (TOC) removal biomass growth were monitored. isolated microb...
