Thanks again for collaborating with us! We had a lot of fun working together with you! Hopefully we can raise awareness of antibiotic resistances and the difficulties that come with diagnosing and treating diseases caused by them. We‘re big fans of your channel, keep up the good work! 🙂
Thank you very much for the video! 😊 In modern medical microbiological diagnostics, PCR methods are also used to detect known resistance genes. These methods are faster than culture-based MIC methods, but also have their limitations, as the resistance mechanisms are still unknown in many bacteria and, moreover, the genotype does not directly correspond to the phenotype of the bacteria. It is also worth mentioning EUCAST, the European Committee on Antimicrobial Susceptibility Testing, which sets clinically relevant thresholds for the MIC of the antibiotic in question to classify its efficacy as S, I, or R. Resistance tests, such as the E-test or the disc diffusion method, can also be used on samples from critically ill patients (e.g., patients with sepsis) to provide initial clues for more targeted antimicrobial treatment (within 24 hours). This is important as definitive identification of the responsible pathogens of an infection can often take several days with standard culture- and MALDI-based methods. A modern facility for MIC determination is the VITEK method: The key element is the VITEK cassette with 64 wells containing multiple different antibiotics and test substances. After inoculation of the isolated bacterial colony for several hours, the respective MIC for every antibiotic can be detected by optical turbidimetry.
