background : microbial monitoring of aquatic sources is essential in the correct management of these vital sources. multiple tube fermentation (mtf) technique is currently used for assessment of the microbial quality of water sources. however, today enzymatic assay has been presented as an alternative approach for detecting indicator bacteria. the purpose of this study was to compare enzymatic ...

Objective This study aimed at validating the method for sterility testing of the corneal culture medium, TISSUE-C, and the transport/deswelling medium, CARRY-C, according to the method suitability test, as defined by the European Pharmacopoeia (EP), using RESEP, which is a new medical device for removal of antimicrobial agents and an automated culture system. Methods and analysis The six EP r...

this study was performed to detect cultivable canine gastric helicobacter-like organisms (ghlo’s) and to evaluate their sensitivity to common antibiotics in two groups of naturally infected dogs (pets and stray dogs). gastric samples were taken from the body and antrum of 30 pets and 30 stray dogs. from each part of canine gastric mucosa, four gastroscopic samples were used for impression smear...

Here we present details on the WFC3/IR spatial sensitivity test. The aim of the test is to observe a standard star in a grid pattern covering the IR detector to investigate spatial variations in the measured photometry. Any deviations from a uniform response could be due to errors in the flat field calibration file. We find that the current pipe-line IR flat-fields, which are a combination of a...

Soils are a sink for sulfidised-silver nanoparticles (Ag2S-NPs), yet there are limited ecotoxicity data for their effects on microbial communities. Conventional toxicity tests typically target a single test species or function, which does not reflect the broader community response. Using a combination of quantitative PCR, 16S rRNA amplicon sequencing and species sensitivity distribution (SSD) m...

A newly developed rapid microbial ATP bioluminescence test (R-mATP) was shown to be an adequate means to assay the microbial load of poultry carcasses. This assay utilizes differential extraction and filtration to separate somatic from microbial ATP in a very rapid timeframe. The assay requires approximately 5 min to complete; approximately 3.5 min to sample and 90 s analytical time. Correlatio...
