Minimizing the Workup of Blood Culture Contaminants: Implementation and Evaluation of a Laboratory-Based Algorithm
An algorithm was implemented in the clinical microbiology laboratory to assess the clinical significance of organisms that are often considered contaminants when isolated from blood cultures and provided an acceptably accurate means for assessing theclinical significance of potential contaminants recovered fromBlood cultures.

Comparison of the Quantum II, API Yeast Ident, and AutoMicrobic systems for identification of clinical yeast isolates
The overall accuracy of the Quantum II, AMS-YBC, and API Yeast Ident systems was not sufficient to recommend any of these systems for routine use in the clinical microbiology laboratory without substantial expansion of the respective data bases. Expand
The importance of positive bacterial cultures of specimens obtained during clean orthopaedic operations.
None of the bacteria that grew on culture were Staphylococcus aureus or the less common pathogenic gram-negative bacteria, such as Escherichia coli, Pseudomonas, or Klebsiella. Expand
Comparison of the Quantum II Bacterial Identification System and the AutoMicrobic System for the identification of gram-negative bacilli
The Quantum II Bacterial Identification System (BID; Abbott Laboratories) is a microprocessor-based spectrophotometric system for identification within 4 to 5 h of both enteric and nonentericExpand
Vancomycin resistance in Staphylococcus haemolyticus causing colonization and bloodstream infection
It is concluded that colonization with a vancomycin-susceptible strain of S. haemolyticus was subsequently linked to a nosocomial bloodstream infection with an apparently identical strain with intermediate levels of vancomYcin resistance. Expand
Histologic chorioamnionitis, microbial infection, and prematurity
The results suggest that histologic chorioamnionitis is not synonymous with infection, especially in the second trimester, and that cases of histologic Chlamydia in the third trimester were associated with positive cultures, compared with 54% in thesecond trimester. Expand
Laboratory evaluation of leukocyte esterase and nitrite tests for the detection of bacteriuria
The sensitivity of the 1-min leukocyte esterase-nitrite combination was too low to allow its use as the only screening test for bacteriuria, but it may serve as a useful adjunct to culturing and other urine-processing systems in the microbiology laboratory. Expand
The usefulness of screening tests for pyuria in combination with culture in the diagnosis of urinary tract infection.
A prospective study to examine the usefulness of screening tests for pyuria in combination with culture in the diagnosis of urinary tract infection in outpatients found pyuria detection by either the chamber count method or the LE test to be extremely useful in directing subsequent culture efforts.

Multicenter comparison of the high volume (10 ml) NR BACTEC PLUS system and the standard (5 ml) NR BACTEC system.
The new system detected positivity at least one reading sooner than twice as often as the converse, and confirmed septic episodes significantly more often, and has distinct advantages over its low blood volume, nonresin counterpart. Expand
Bacterial scleral abscesses after retinal buckling operations. Pathogenesis, management, and laboratory investigations.
A laboratory investigation showed that a cell-free millipore filtrate of Staphylococcus aureus culture in trypticase soy broth caused prominent but self-limited inflammation when injected intravitreally, which could be the cause of the prominent vitreous inflammation in most patients with scleral abscesses.
