in the present study a new economic and rapid bacterial micro-assay for simultaneous detection and quantitative measurement of serum galactose was developed. analysis of the standard curve showed a linearity range for galactose from 2 mg/dl to 180 mg/dl with a regression equation of y = 0.013x ? 0.083; r² = 0.962. the advantage of the method is its ability to measure serum galactose quantitativ...

BACKGROUND The aim of this study was to confirm recent results from a previous study focussing on the development of a method to measure the bacterial translocation through puncture holes in surgical gloves under real surgical conditions. METHODS An established method was applied to detect bacterial migration from the operating site through the punctured glove. Biogel double-gloving surgical ...

Aggregates play a key role in protecting soil organic carbon (SOC) from microbial decomposition. The objectives of this study were to investigate the influence of pore geometry on the organic carbon decomposition rate and bacterial diversity in both macro- (250-2000 μm) and micro-aggregates (53-250 μm) using field samples. Four sites of contrasting land use on Alfisols (i.e. native pasture, cro...

Our objective in this study was to characterize prokaryotic sulphide production within the oxygenic, predominantly eukaryotic algal mat in an acidic stream, Nymph Creek, in Yellowstone National Park (YNP). We used microsensors to examine fluctuations in H2S and O2 concentrations over time through the vertical aspect of the approximately 3 mm mat in a 46-48 degrees C region of the creek. We also...

Soil is known to be heterogeneous for different activities at several spatial scales. Most studies have focused on macro- and meso-scales but micro-scales are rarely addressed. Hence, the spatial structure of NH(4)(+)- and NO(2)(-)-oxidizers and of various serotypes of the latter was studied along two transects of approximately 10 cm, with two micro-samples taken from each millimeter. The prese...

Bacterial meningitis, a world-wide disease, has to be reviewed periodically because the specific micro-organisms responsible for the infection vary with time, geography and patient age. To determine its incidence and clinical features in Taiwan, we reviewed the microbiological records for cerebrospinal fluid (CSF) and blood cultures, and the medical records of patients with bacterial meningitis...

background :   this study aimed to evaluate antibacterial effect of allium sativum, garlic extract on erythromycin and methicillin resistant bacteria isolated from an operating room in a teaching hospital in tehran, i.r. iran.   methods :   the antibacterial effect of garlic extract was investigated on 70 bacterial strains. the selected isolates were resistant to erythromycin and or methicillin...
