Over five years the Bactec radiometric blood culture method yielded Salmonella typhi in 41 of 45 confirmed cases of typhoid fever, 90% of which were from the first culture set taken. Blood clot culture was positive in 18 (41%) of 44 confirmed cases and stool culture in 24 (59%) of 41. The yield from 2189 Widal clot cultures was only 0.03%. There were 68 positive results in 2258 unpaired Widal t...

The BACTEC MGIT 960 instrument is a fully automated system that exploits the fluorescence of an oxygen sensor to detect growth of mycobacteria in culture. Its performance was compared to those of the radiometric BACTEC 460 instrument and egg-based Lowenstein-Jensen medium. An identical volume of sample was inoculated in different media, and incubation was carried out for 6 weeks with the automa...

The BACTEC resin-containing blood culture bottle (16B; Johnston Laboratories) was designed to bind antibiotics and to support bacterial growth. However, only modest increases in the recovery rates of pathogens have been found in clinical studies. This in vitro study evaluated the ability of the 16B to recover organisms from human serum containing clinically achievable concentrations of antibiot...

BACKGROUND Brucellosis is a zoonosis disease which is widespread across the world. OBJECTIVES The aim of the present study is the evaluation of culture-negative blood samples. MATERIALS AND METHODS A total of 100 patients with suspected brucellosis were included in this experimental study and given positive serological tests.

Methods We studied the role of these biomarkers with clustered gram-positive and gram-negative bacteremia in patients hospitalized in Intensive care Unit over a period of 2 years (2011-2013), they were measured within the 24 hours after the onset of severe sepsis or septic shock. The PCT was analyzed by immunoassay (Vidas, Brahms), lactate and CRP was measured in DIMENSION RXL SIEMENS and blood...
