Cultures were performed according to the working protocol of the Bacteriology Laboratory of SCJUPBT. All isolates were first identified using the VITEK® 2 GN, VITEK® 2 GP ID cards (BioMérieux, Marcy l’Etoile, France). Antimicrobial susceptibility tests (AST) were performed using the VITEK 2 GN AST-N222 and VITEK 2 AST GP 67 cards (BioMérieux, Marcy l’Etoile, France) by determination of the minimum inhibitory concentration (MIC) and classification into resistance phenotypes, according to the Clinical Laboratory and Standards Institute (CLSI) 2020/2021 criteria. The reference strains used were: Escherichia coli ATCC 25922 and Klebsiella pneumoniae ATCC 1705, Pseudomonas aeruginosa ATCC 27853, Staphylococcus aureus ATCC 25923. Clostridioides difficile enterocolitis was diagnosed by determining the A and/or B toxin from the spontaneously emitted feces by using the LIAISON® Analyzer through an automatic immunoassay testing.

Expectorate sputum was selected as the sampling technique and routine microbiological investigations were conducted at the medical microbiology laboratory using standard bacteriology. All isolates were first identified using the VITEK® 2 GN and VITEK® 2 GP ID cards (BioMérieux, Marcy, l’Etoile, France). Antimicrobial susceptibility tests were performed using the VITEK 2 GN AST-N222 and VITEK 2 AST GP 67 cards (BioMérieux, Marcy, l’Etoile, France).
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.
