A total of 329 selective enrichment broth cultures were tested for detection of Clostridium difficile by latex particle agglutination (LPA), gas-liquid chromatography, and bacterial culture. Of 53 broths positive by LPA, 36 were positive by gas-liquid chromatography, and 42 were positive by bacterial culture. The sensitivity and specificity of LPA relative to bacterial culture was 95.6% and 96....
گیاهان دارویی در طول تاریخ بشر در درمان بیماریها استفاده می شدند.از این رو ما در این پایان نامه اثر آنتی باکتریال عصاره تام و فراکسیون های اتردوپترولی و آبی حاصل از گیاه calotropis procera را بررسی کردیم.در این مطالعه روش ما برای عصاره گیری روش liquid-liquid fraction بودوعصاره تامو فراکسیون های اتر دوپترولی وآبی تهیه شد.برای روش میکروبی از روش انتشار در محیط آگار استفاده کردیمو به روش چاهک پلیت...
BACKGROUND Active tuberculosis (TB) must be excluded before initiating isoniazid preventive therapy (IPT) in persons infected with human immunodeficiency virus (HIV), but currently used screening strategies have poor sensitivity and specificity and high patient attrition rates. Liquid TB culture is now recommended for the detection of Mycobacterium tuberculosis in individuals suspected of havin...
We describe a novel protocol for three-dimensional culturing of olfactory ensheathing cells (OECs), which can be used to understand how OECs interact with other cells in three dimensions. Transplantation of OECs is being trialled for repair of the paralysed spinal cord, with promising but variable results and thus the therapy needs improving. To date, studies of OEC behaviour in a multicellular...
Acid phosphatase activities in a culture liquid and mycelial extract were studied in submerged cultures of the filamentous fungus Humicola lutea 120-5 in casein-containingmedia with and without inorganic phosphate (Pi). The Pi-repressible influence on the phosphatase formation was demonstrated. Significant changes in the distribution of acid phosphatase between the mycelial extract and culture ...
The removal of bacterial populations from large volumes of liquid culture media may be accomplished readily using a centrifuge, but the usual efficient continuous-feed type of centrifuge is often large and expensive. In this laboratory, during the past 2 years, bacterial cells have been removed from liquid culture with considerable success, using a small, inexpensive, continuously fed centrifug...
