Microbial pollution in aquatic environments is one of the crucial issues with regard to the sanitary state of water bodies used for drinking water supply, recreational activities and harvesting seafood due to a potential contamination by pathogenic bacteria, protozoa or viruses. To address this risk, microbial contamination monitoring is usually assessed by turbidity measurements performed at d...

BACKGROUND Infection control is a key issue in podiatry as it is in all forms of clinical practice. Airborne contamination may be particularly important in podiatry due to the generation of particulates during treatment. Consequently, technologies that prevent contamination in podiatry settings may have a useful role. The aims of this investigation were twofold, firstly to determine the ability...

Aims: To clarify the usefulness of preservative-free ophthalmic preparations equipped with a filter. Methods: A total of 1,615 samples of in-use ophthalmic preparations were examined for microbial contamination. Results: Of 1,094 samples of preservative-containing ophthalmic preparations, 31 (2.8%) showed microbial contamination. Of 289 samples of preservative-free ophthalmic preparations witho...

this study was conducted to investigate the bacterial contamination of small ruminant carcasses in traditional slaughterhouses of tehran province, in summer and winter seasons. 30 sheep and goat carcasses from slaughterhouses of rey, shahreyar and eslamshahr were evaluated. در انتهای خط کشتار و قبل از مرحله توزیع، از لاشه دامها نمونه برداری شد. randomly samples were taken at the end of the slau...

OBJECTIVES Intravenous therapy is a complex procedure usually requiring the preparation of the medication in the clinical area before administration to the patient. Breaches in aseptic technique may result in microbial contaminations of vials which is a potential cause of different avoidable infections. We aimed to investigate the prevalence and pattern of microbial contamination of single- and...

Introduction. Data regarding methicillin-resistant Staphylococcus aureus, Legionella pneumophila, Hepatitis B virus suggest that the environment plays an important role in infection transmission in dental healthcare settings. The Centres for Disease Control and Prevention suggest covering clinical contact surfaces with disposal barriers or disinfecting them between patients. Both methods have d...

A novel approach based on headspace solid-phase microextraction (HS-SPME) combined with comprehensive two-dimensional gas chromatography-time-of-flight mass spectrometry (GC×GC-ToFMS) was developed for the simultaneous screening of microbial and mite contamination level in cereals and coffee beans. The proposed approach emerges as a powerful tool for the rapid assessment of the microbial contam...

Protocols for microbial source tracking of fecal contamination generally are able to identify when a source of contamination is present, but thus far have been unable to evaluate what portion of fecal-indicator bacteria (FIB) came from various sources. A mathematical approach to estimate relative amounts of FIB, such as Escherichia coli, from various sources based on the concentration and distr...
