چکیده

It has been recommended that routine microbiological processing of urine specimens include quantitative plating onto blood agar medium along with a selective and differential agar such as MacConkey agar for gram-negative organisms. Few data have been published to justify this combination. To evaluate the validity of this recommendation 2,553 midstream, clean-voided urine samples were quantitatively plated onto blood agar, MacConkey agar, and colistin-nalidixic acid agar, which is a selective medium for gram-positive organisms. The amounts of growth on each of the three media were compared. Results indicated that the best medium combination was colistin-nalidixic acid agar and MacConkey agar. The use of colistin-nalidixic acid agar instead of blood agar increased the detection of significant growth of enterococci, lactobacilli, and Torulopsis glabrata.

Comparison of CPS ID 3 and CHROMagar Orientation chromogenic agars with standard biplate technique for culture of clinical urine samples.

BACKGROUND AND PURPOSE Chromogenic agars have been developed to recognize frequently occurring microorganisms directly on primary cultures, thus reducing the daily workload in a clinical microbiology laboratory. We compare two chromogenic agars, CHROMagar Orientation (CO) and CPS ID 3 (CPS3), with routine media (biplate technique using trypticase soy blood agar and eosin methylene blue agar) fo...

Laboratory diagnosis of fungal infections

Selection of appropriate specimens for culture and microscopic examination is based on the results of clinical and radiographic examination and consideration of the most likely fungal pathogen that may cause such an infection. Specimens should be collected under aseptic conditions or after appropriate cleaning and decontamination of the collection site and rapidly transported to the clinical my...

Anaerobic infections of the urinary tract: are they being missed?

Routine anaerobic culture of urine identified the urinary tract as the primary focus of sepsis in a postoperative patient with Bacteroides fragilis septicaemia. Specimens of urine from six other symptomatic patients grew > 10(8) cfu/litre of a Bacteroides species in pure growth. The significance of these isolates is discussed. Multipoint technology and the availability of anaerobic work station...

Evaluation of the Chromogenic Medium (CPS) in the Isolation and Identification of Urinary Tract Pathogens

Urinary tract infection, Chromogenic media Background: Urine cultures constitute the majority of the workload for a microbiology laboratory with only 20%-30% of urine sample resulting in significant growth. Chromogenic media (CM) are available for urine specimens to enable rapid identification of common pathogens and also has been reported to increase mixed culture detection, reducing unnecessa...

Culture of Urine Specimens by Use of chromID CPS Elite Medium Can Expedite Escherichia coli Identification and Reduce Hands-On Time in the Clinical Laboratory.

Urine is one of the most common specimen types submitted to the clinical microbiology laboratory; the use of chromogenic agar is one method by which the laboratory might expedite culture results and reduce hands-on time and materials required for urine culture analysis. The objective of our study was to compare chromID CPS Elite (bioMérieux), a chromogenic medium, to conventional primary cultur...
