Different result from blast hit

[MonicaSteffi]

Dear Developer,

Thank you so much for Kaiju. I performed spade assembly (for the virus) and performed kaiju on assembled contigs. For the reference database, I downloaded the viral database from the kaiju web server and completed the taxonomic assignment (with default options).

I got one characterized contig belonging to "Gordonia phage Gustav". I blasted the same contigs using blastn option and I got the best hit as "Podoviridae sp". They both belong to the same class though.

How do I confirm these results at the species or genus level?

Any help would be appreciated

Thank you in advance

Regards Monica
