Aim. The molecular identification of Pycnoporus sanguineus, a previously morphologically  mushroom, was done to see the antibacterial activity against pathogenic bacteria Staphylococcus aureus and Salmonella typhi.

Methods. A fragment of the D2 region of 28S rDNA was amplified by PCR, sequenced, and BLAST was performed using the consensus sequence. The maximum identity score was used to build a phylogenetic tree. Agar well diffusion was used to study the antibacterial activity.

Results. Sequencing of a 700 base pair PCR amplicon was carried and a 616 base pair of D2 region of large subunit gene was generated. The 100 blast hits on the D2 region of LSU gene showed similarity to Trametes sanguineus voucher PRSC95 (GenBank Accession Number: JN164795.1) based on nucleotide homology and phylogenetic analysis. Antibacterial screening revealed that the crude extract had higher activity on Staphylococcus aureus, with a 3mm to 13mm zone of inhibition and a 100µg minimum inhibitory concentration, compared to Salmonella typhi. Salmonella typhi had a 5 mm to 15 mm zone of inhibition and a 200 µg minimum inhibitory concentration.

Conclusion. According to the obtained result, the morphologically identified mushroom Pycnoporus sanguies can be referred to as Trametes sanguine, and it can be used for producinig antibacterial agents.
