To determine optimal clinical laboratory techniques for detecting pediatric bacteremia, we studied 7,768 consecutive blood cultures in a 1-year period. Blood was inoculated into one vented 50-ml bottle of brucella broth with 0.05% sodium polyanetholsulfonate and one unvented 50-ml bottle of Columbia broth with 0.05% sodium polyanetholsulfonate and 0.05% cysteine. Bottles were visually examined ...

Congenital leukemia is a rare disease which in clinically evident at birth or apparent within the first few weeks of life; The disease is more common in infants with downs syndrome.  We present a case of combined mongolism and congenital leukemia and reviewe some aspect of the disease. 

conclusions the remarkable rates of biofilm production ability among clinically isolated staphylococci emphasize the necessity of more effective infections control policies to prevent biofilm formation on medical devices and hospital environmental surfaces. background biofilm formation capacity is recognized as an important virulence factor in staphylococci that makes the organisms more resista...

The accuracy of Vitek MS mass spectrometric identifications was assessed for 206 clinically significant isolates of aerobic Gram-positive bacilli representing 20 genera and 38 species. The Vitek MS identifications were correct for 85% of the isolates (56.3% to the species level, 28.6% limited to the genus level), with misidentifications occurring for 7.3% of the isolates.

nosocomial infections of multidrug-resistant pseudomonas aeruginosa (mdrpa) are a growing concern in hospitalized patients in burn centers. the aim of this study was to investigate the flagellin profiling and antibiotic susceptibility of p. aeruginosa isolated from burn wound infections. during 8 month study, 73 clinically p. aeruginosa isolates collected from patients hospitalized in burn ward...

Genetic markers previously reported to occur at significantly different frequencies in isolates of Escherichia coli O157:H7 obtained from cattle and from clinically affected humans concordantly delineate at least five genetic groups. Isolates in three of these groups consistently carry one or more markers rarely found among clinical isolates.

Background: Enterococci faecalis are predominating species of Enterococci causing nosocomial infections. Acquisition of resistance to antibacterial agents, and ability to transfer the resistant genes made them clinically important. This study was performed to determine the frequency of isolation of different species of Enterococci, and the antibacterial resistance pattern of the isolated specie...
