Comparative Genomics Reveals Intra and Inter Species Variation in the Pathogenic Fungus Batrachochytrium dendrobatidis.
Article in Genome biology and evolution, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The Global Panzootic Lineage (GPL) of Batrachochytrium dendrobatidis (Bd) has been described as a main driver of amphibian extinctions. Pathogen studies have benefited from three Bd-GPL strain genomes, but identifying the genetic and molecular features that distinguish the B. dendrobatidis lineages requires additional high-quality genomes from diverse lineages. We sequenced and assembled genomes with Oxford Nanopore Technologies to produce assemblies of three Bd-BRAZIL isolates and one nonpathogen outgroup species Polyrhizophydium stewartii. The Bd-BRAZIL assembly sizes ranged between 22.0 and 26.1 Mb with 8,495 to 8,620 predicted protein-coding genes. We sought to categorize the pangenome of the species by identifying homologous genes across the sampled genomes as either being core and present in all strains, or accessory and shared among strains in a lineage, an analysis that has not yet been conducted on B. dendrobatidis and its lineages. We identified a core genome consisting of 6,278 gene families, and an accessory genome of 202 Bd-BRAZIL and 172 Bd-GPL specific gene families. We discovered copy number differences in pathogenicity gene families: M36 Peptidases, Crinkler Necrosis genes, Aspartyl Peptidases, Carbohydrate-Binding Module-18 genes, and S41 Proteases, between Bd-BRAZIL and Bd-GPL strains. Comparison of B. dendrobatidis and two closely related saprophytic species identified differences in protein sequence and domain counts for M36 and CBM18 families respectively. Our pangenome analysis of lineage-specific gene content led us to explore how the selection of the reference genome affects recovery of RNAseq transcripts when comparing different strains. We tested the hypothesis that genomic variation among Bd-GPL and Bd-BRAZIL lineages can impact transcript count data by comparing results with our new Bd-BRAZIL genomes as the reference genomes. Our analysis examines the genomic variation between strains in Bd-BRAZIL and Bd-GPL and offers insights into the application of these high-quality reference genomes resources for future studies.
