Fig. 3

The heat map represents the distribution of reads for viral families. The figure displays the viral families that were detected and reads that could not be classified into families, such as Caudovirales. The quantity of reads is shown using a color gradient ranging from red, indicating the highest quantity, to blue for families with the lowest quantity. Myoviridae, Podoviridae, and Siphoviridae, which are among the eight phage families detected, as well as Mimiviridae that infects protists, had a significant number of reads. The Melgaço 1 sample exhibited the highest read counts for Siphoviridae and Myoviridae, as depicted by the red rectangles in the bottom right corner of the heatmap. On the other hand, RNA viruses were predominantly represented by the Retroviridae family across all samples
