Surveillance of colonization by MDRO

Swabs were performed using sterile transport swab (ref. 139C) on specific media (liquid Stuart, Venturi Transystem® by COPAN Italia, Brescia, Italy).
Each swab was cultivated on specific selective media (chromID® VRE and chromID® CARBA SMART by bioMérieux, Marcy l’Etoile, France), and on regular MDRO agar plates according to manufacturer. No enrichment cultures were used.
Moreover, at admission colonization was systematically confirmed by PCR testing (PCR Xpert CarbaR and Xpert VanA/VanB by Cepheid, Maurens-Scopont®, France) and during follow-up in case of negative culture on the demand of physician.

Skin Infection: Microbial Identification and Antibiotic Susceptibility

Check if the same lab product or an alternative is used in the 5 most similar protocols

Skin swab cultures (sterile transport swab on Stuart agar gel medium, Copan Venturi Transystem®; Copan, Murrieta, CA, USA) were performed at suspected sites of skin infection and then inoculated on blood agar plates followed by McConkey agar plates. They were subsequently incubated in a carbon dioxide (CO₂) incubator set at 35℃ and 5% CO₂ for 1 day (Thermo Scientific Inc., Waltham, MA, USA). Gram staining was performed in the presence of colonies on inoculated culture medium. Gram-positive bacteria were judged to be S. aureus when their catalase and coagulase tests were positive, and CoNS was determined according to negative catalase and coagulase results. Subsequently, the specimens were inoculated on Mueller-Hinton agar and tested for susceptibility to antibiotics by disk diffusion method.
For other species, automation equipment, including VITEK 2 (bioMerieux Inc., Hazelwood, MO, USA) and MicroScan (Beckman Coulter Inc., Brea, CA, USA), was used for microbial identification and antibiotic susceptibility tests.

Demographic and Risk Factors Survey

Check if the same lab product or an alternative is used in the 5 most similar protocols

After informed consent and assent (when appropriate) were obtained, participants and legal guardians were administered a survey pertaining to their demographic, personal and household members’ risk factors (Table 1). Two swabs were then collected, one each from the anterior nares and axillae. For the nares, a cotton-tipped swab (Copan Venturi Transystem® with Liquid Stuart Medium) was rotated three times in the anterior portion of each naris. For the axilla, three to five brush strokes under each axillary area were taken. Moistened swabs were then transported immediately to the clinical microbiology laboratory for plating on selective and non-selective media. The institutional review boards of participating institutions approved this study.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
