Comparing Microsporidia-targeting primers for environmental DNA sequencing.

ABSTRACT: Metabarcoding is a powerful tool to detect classical, and well-known "long-branch" Microsporidia in environmental samples. Several primer pairs were developed to target these unique microbial parasites, the majority of which remain undetected when using general metabarcoding primers. Most of these Microsporidia-targeting primer pairs amplify fragments of different length of the small subunit ribosomal RNA (SSU-rRNA) gene. However, we lack a broad comparison of the efficacy of those primers. Here, we conducted in silico PCRs with three short-read (which amplify a few-hundred base pairs) and two long-read (which amplify over a thousand base pairs) metabarcoding primer pairs on a variety of publicly available Microsporidia sensu lato SSU-rRNA gene sequences to test which primers capture most
