Currently, phenotypic characterization is routinely used in diagnostic laboratories for antibiotic resistance measurement due to its cost-effectiveness. With the advent of molecular diagnostic technologies that offer shorter turnaround times and more comprehensive data on antibiotic resistance, is there any chance that they will replace phenotyping and become standardized in practice?
The forecast for the employment of molecular-based methods in monitoring antibiotic resistance is quite promising. These methods, which include techniques like polymerase chain reaction (PCR), whole-genome sequencing, and microarray analysis, offer rapid and accurate detection of antibiotic resistance genes in bacterial populations.As antibiotic resistance continues to pose a significant global health threat, there's a growing recognition of the need for more efficient and precise methods for monitoring and tracking resistance patterns. Molecular-based methods provide several advantages over traditional culture-based techniques, including faster turnaround times, higher sensitivity and specificity, and the ability to detect resistance genes even in non-culturable bacteria.
Hello Rianna May Kwan,
Molecular characterization of the genetic mechanism underlying a given phenotypic result which is obtained by traditional phenotypic testing, is now turning to be an integral part of many clinical investigations in relation to bacterial infections.
When phenotypic results become too time-consuming, non-conclusive, or unavailable, it is the molecular- based analysis that is used to investigate the presence of a given gene or point mutation, thereby giving direct support to ensure that an optimal treatment or control strategy is undertaken in a timely manner.
For instance, molecular-basis methods may be used to aid in epidemiological investigations following an outbreak, when phenotypic data is not sufficiently detailed to control possible outbreaks involving resistant bacteria.
The traditional phenotypic testing may not be replaced due to it's cost- effectiveness. But at the same time molecular-based techniques may be used for genotypic detection of antimicrobial resistance genes.
Best.
The forecast for the employment of molecular-based methods in the monitoring of antibiotic resistance is promising. These methods, such as PCR (Polymerase Chain Reaction) and next-generation sequencing, offer rapid and accurate detection of resistance genes in pathogens. As technology continues to advance, these molecular techniques are likely to become standard procedures in clinical settings and public health laboratories for monitoring antibiotic resistance. Additionally, the integration of bioinformatics tools and data analytics will enhance the interpretation of molecular data, facilitating more informed decisions in antibiotic prescribing and surveillance efforts. Overall, the future outlook suggests an increasing reliance on molecular-based methods for monitoring and combating antibiotic resistance.
The forecast suggests that molecular-based methods will increasingly become standard procedures in monitoring antibiotic resistance. These methods offer advantages such as speed, accuracy, and the ability to detect multiple resistance genes simultaneously. As technology advances and becomes more accessible, these methods are likely to become more widely adopted in clinical and public health settings for monitoring antibiotic resistance trends and guiding treatment decisions.
