Detection of methicillin-resistant Staphylococcus aureus in clinical specimens from cystic fibrosis patients by use of chromogenic selective agar.
We evaluated the use of a chromogenic selective medium (MRSA ID) as a useful tool for the detection of methicillin-resistant Staphylococcus aureus (MRSA) in cystic fibrosis (CF) patient samples. Fifty-four MRSA isolates were detected by MRSA ID, while only 24/54 (44%) (odds ratio [OR], 2.79; 95% confidence interval [CI], 1.63 to 4.76) were detected by conventional methods. A chromogenic selecti...
متن کاملEvaluation of a new selective medium, BD BBL CHROMagar MRSA II, for detection of methicillin-resistant Staphylococcus aureus in stool specimens.
We compared the recovery of methicillin-resistant Staphylococcus aureus (MRSA) on a new selective chromogenic agar, BD BBL CHROMagar MRSA II (CMRSAII), to that on traditional culture media with 293 stool specimens. The recovery of MRSA was greater on the CMRSAII agar. Screening of stool samples can identify patients who were previously unknown carriers of MRSA.
متن کاملInfluence of Broth Enrichment as well as Storage and Transport Time on the Sensitivity of MRSA Surveillance in the Tropics
Direct growth on blood and screening agar for methicillin-resistant Staphylococcus aureus (MRSA) at a tropical surveillance site was compared with broth enrichment and subsequent growth on selective MRSA agar after international sample transport. In Madagascar, 1548 swabs from an MRSA surveillance study were assessed for growth on Columbia blood agar enriched with 5% sheep blood and MRSA screen...
متن کاملModelling the Costs and Effects of Selective and Universal Hospital Admission Screening for Methicillin-Resistant Staphylococcus aureus
BACKGROUND Screening at hospital admission for carriage of methicillin-resistant Staphylococcus aureus (MRSA) has been proposed as a strategy to reduce nosocomial infections. The objective of this study was to determine the long-term costs and health benefits of selective and universal screening for MRSA at hospital admission, using both PCR-based and chromogenic media-based tests in various se...
متن کاملCULTURES FOR METHICILLIN - RESISTANT STAPHYLOCOCCUS AUREUS FROM 29 COLONIZED PATIENTS Site Samples Nose
Ceftazidime proved an excellent selective antibiotic for this MRSA in subcultures from the enrichment medium; interference from contaminating flora was noted only sporadically. MRSA was clearly visible after 24 hours of incubation. Moreover, no MRSA could be detected after 48 hours of incubation if it was not already visible after 24 hours on this medium. Overall, MRSA colonies were larger with...
متن کاملUse of a primary isolation medium for recovery of methicillin-resistant Staphylococcus aureus.
Clinical specimens frequently contain methicillin-resistant Staphylococcus aureus (MRSA) isolates in low numbers or mixed with methicillin-susceptible staphylococci, which can obscure MRSA on nonselective media. By using an oxacillin-containing mannitol-salt-based selective and differential medium on 936 respiratory specimens, we recovered 45% more MRSA isolates (29 versus 20) than on nonselect...
