Prolonged incubation and extensive subculturing do not increase recovery of clinically significant microorganisms from standard automated blood cultures.
An extensive blood culture protocol, including prolonged incubation of cultures, for 215 patients believed to have had endocarditis yielded only 3 clinically relevant results. Twenty-four Haemophilus, Actinobacillus, Cardiobacterium, Eikenella, and Kingella (i.e., HACEK) organisms were recovered from standard 5-day blood cultures during the same time period. Specialized methods and not extended...
متن کاملIs incidental recovery of yeast from enteric pathogen stool cultures obtained from hospitalized patients clinically significant?
A matched case-control study was conducted to investigate gastrointestinal colonization with yeast as a predictor of invasive candidiasis (IC) in patients who underwent an enteric pathogen test. No significant association was detected between gastrointestinal colonization and IC. However, gastrointestinal colonization with yeast was associated with increased antimicrobial exposure and median le...
متن کاملRoutine testing for anaerobic bacteria in cerebrospinal fluid cultures improves recovery of clinically significant pathogens.
In North America, the widespread use of vaccines targeting Haemophilus influenzae type b and Streptococcus pneumoniae have dramatically altered the epidemiology of bacterial meningitis, while the methodology for culturing cerebrospinal fluid (CSF) specimens has remained largely unchanged. The aims of this study were 2-fold: to document the current epidemiology of bacterial meningitis at a terti...
متن کاملRapid detection of positive blood cultures with the BACTEC NR-660 does not require first-day subculturing.
An analysis of blood culture data was performed to determine whether subculturing within the first 24 h of incubation decreased the time to detection of positive blood cultures when compared with the routine use of the BACTEC NR-660 system (Johnston Laboratories, Inc., Towson, Md.). During a 9-month period (June 1985 to February 1986), 17,913 blood cultures were received in our laboratory, of w...
متن کاملEvaluation of anaerobic incubation for recovery of group A streptococci from throat cultures.
No statistical differences were found in the recovery of group A streptococci from throat culture specimens after overnight incubation of blood agar plates in 5% CO2 compared with anaerobiosis. Anaerobic incubation required many more subcultures and resulted in considerably greater technical time and expense.
