Amplicon Sequencing for Drug Resistance Surveillance

Amplicon Sequencing for Drug Resistance Surveillance

Amplicon sequencing, a focused approach utilizing next-generation sequencing (NGS) technologies, has become an indispensable tool in the surveillance of drug resistance, especially in infectious diseases such as malaria. This method allows researchers to selectively amplify and sequence specific regions of the genome, facilitating the detailed study of genetic mutations associated with resistance to drugs.

Why Targeted Next-Generation Sequencing (tNGS) is Important for Malaria Research

While traditional methods have laid the groundwork for understanding malaria, they often don’t provide the necessary detail to fully explore the genetic complexities of the Plasmodium parasite. The CleanPlex Malaria Research NGS Panel from Paragon Genomics marks a significant advancement by enhancing the scope and depth of malaria research through targeted next-generation sequencing (tNGS):

• Deep Genetic Insights: Provides details into the intricate genetic landscape of the malaria parasite, exposing biological details and interactions that are pivotal for developing targeted therapies.
• Speed in Scientific Discovery: tNGS accelerates the identification process for genetic markers of drug resistance and pathogenicity. This rapid profiling helps in quicker formulation of responses and therapies.
• Precision in Public Health Interventions: With its ability to produce precise and high-resolution genetic data, tNGS refines the accuracy of epidemiological tracking and the crafting of intervention strategies.

How Amplicon Sequencing Helps Researchers Learn More About Malaria

Amplicon sequencing has not only revolutionized antimalarial drug resistance surveillance but has also shed light on the complexities of malaria infections, particularly through its ability to investigate Plasmodium falciparum and its genetic diversity. Specifically, it helps with:

• Tracking Plasmodium Falciparum Asymptomatic Infections: Asymptomatic infections pose significant challenges in malaria control because they often go undetected yet serve as reservoirs for transmission. Amplicon sequencing enables the detection of P. falciparum in asymptomatic individuals.
• Exploring Genetic Diversity: The genetic diversity of P. falciparum is a major determinant of its virulence and drug resistance. By analyzing variations within drug resistance markers and across the genome, researchers can gain insights into the evolution of resistance and virulence traits in different geographical regions.
• Molecular Epidemiology Insights: Amplicon sequencing contributes to malaria molecular epidemiology by providing detailed data that can link genetic variations of P. falciparum with specific clinical outcomes, such as the occurrence of febrile infections.
• Revealing Febrile Infections: Often, febrile infections in endemic areas are presumptively treated as malaria without laboratory confirmation. Amplicon sequencing can confirm the presence of P. falciparum in febrile patients, helping to differentiate malaria from other causes of fever and ensuring appropriate treatment.

Challenges of Using Amplicon Sequencing for Drug Resistance Surveillance

Despite its many advantages, amplicon sequencing faces some challenges when it comes to drug resistance surveillance:

• Sample Quality and Preparation: The quality of DNA extracted from samples can impact the sequencing results, with degraded or contaminated samples leading to inaccurate data.
• Complexity in Data Analysis: Interpreting the massive amounts of data generated by NGS can be daunting and requires sophisticated bioinformatics tools and expertise.

Despite these challenges, amplicon sequencing remains a cornerstone in the fight against drug-resistant pathogens due to its precision and efficiency.
