BACKGROUND Human Rhinovirus infection is an important precursor to asthma and chronic obstructive pulmonary disease exacerbations and the Human Viral Challenge model may provide a powerful tool in studying these and other chronic respiratory diseases. In this study we have reported the production and human characterisation of a new Wild-Type HRV-16 challenge virus produced specifically for this...

The bitter gourd is bringing health benefits to human; however bitterness of the fruit limits its therapeutic effects. Fermentation processes have been reported be able reduce gourd. In this study, effects fermentation factors including time (0, 12, 24, 36, 48, 60 and 72h), temperature (20, 25, 30, 35 40℃) inoculum volume (v/w) 1, 5, 10, 15 20%) Lactobacillus plantarum on pH, total soluble soli...

We studied six methods for preparation of inoculum to use in susceptibility tests of anaerobic bacteria to determine viable counts of 15 different species of anaerobes. We counted viable bacteria for each method-organism combination. Methods studied included those used for the more routine tests (broth microdilution and broth-disk elution) and for the National Committee for Clinical Laboratory ...

Production of single cell protein (SCP) from natural gas in a one liter bubble column reactor and optimization of the process parameters were investigated. The medium specifications, nitrogen sources, initial inoculum volume, and inlet ratio of gas to air were considered as process parameters to be optimized. The optimum condition for highest biomass production in which the maximum quantity of ...

Knowledge of host resistance, inoculum levels, and weather conditions favorable for disease development is necessary to optimize a disease forecaster. A group of plant pathologists from five land-grant universities (North Dakota, Ohio, Pennsylvania, Purdue, and South Dakota) have collaborated to develop and improve performance of a disease forecasting system for Fusarium Head Blight (FHB). The ...

Sir, We read with great interest the article by Udekwu et al. on the relationship between bacterial cell density and antibiotic efficacy. These authors have nicely shown by using in vitro time–kill, MIC estimation and antibiotic bioassay experiments modest or substantial inoculum effects on the efficacy of six antibiotics against Staphylococcus aureus. Using a sophisticated mathematical model, ...

Biochar (BC) recently gained attention as an additive for anaerobic digestion (AD). This work aims at a critical analysis of the effect six BCs, with different physical and chemical properties, on AD mixed wastewater sludge 37 °C, comparing their influence methane production kinetics. batch tests were performed laboratory scale operating 48 reactors (0.25 L working volume) 28 days addition 10 g...

Abstract Background Rifaximin, a semi-synthetic antimicrobial, does not present microbiological method described in official compendia, and there is lack of literature on this topic. The quality control antimicrobials extremely important to evaluate the real potency pharmaceutical products. Objective A miniaturized turbidimetric for determining rifaximin tablets was developed validated by turbi...
