Eighty group G streptococcal stains were collected from Chinese children. Susceptibility testing was done by a double-dilution and a disk diffusion method. PCR was used to test drug-resistant genes, and the χ(2) test and definite probability methods were used to test for statistically significant differences among the three groups. Thirty-four isolates (42.5%) showed resistance to erythromycin....

Regardless of the supremacy of relational database management systems (RDBMS) in the databases, object-oriented database management systems (OODBMS) continue to play crucial role in the management of data. Generally, the complex data are often found in telecommunications, business, engineering and web based applications. The most common approach of accessing such data is navigation. However, th...

Massive young stellar objects (YSOs) are powerful infrared H I line emitters. It has been suggested that these lines form in a outflow from a disk surrounding the YSO. Here, new two-dimensional Monte Carlo radiative transfer calculations are described which test this hypothesis. Infrared spectra are synthesised for a YSO disk wind model based on earlier hydrodynamical calculations. The model sp...

OBJECTIVES The objective of this study was to determine the occurrence of chromosomal and plasmid-mediated β-lactamases (AmpC) genes in a collection of Malaysian isolates of Enterobacter species. Several phenotypic tests for detection of AmpC production of Enterobacter spp. were evaluated and the agreements between tests were determined. METHODS Antimicrobial susceptibility profiles for 117 E...

background and aim: the double dichotic digit test (ddt) is a simple test for assessing and screening auditory processing system. the purpose of this study was to develope a double ddt, in persian language and find its basic norm values in girls aged 7 to 11 years. methods: the persian version of double ddt is composed of 3 different 25 numerical lists. numbers in each list were recorded dichot...

background : the emergence and increase in the incidence of extended-spectrum beta lactamase (esbl) producing escherichia coli has become an emerging challenge especially in hospitalized patients with uti. the aim of the present study was to survey the frequency of bla ctx-m genotype in esbl producing e. coli isolated from hospitalized patients with uti and determination of their antibiotic res...
