That's just wow
From my collegiate/med courses such as immunology, virology, and pathogenic micro... My professors have always emphasized bacterium sizes in relation to viral counterparts that produce similar pathogenicity/virulence..perhaps through integrations/IGG mimics to induce competitive inhibitions and cofactors this novel virus can prove to be useful in human applications. Otherwise, this curiously denotes types of basal/rudimentary immune complexes(which is in due nature due to depth atrophy of lymphatic/ganglionic structures) that host such a large virus. This type of virus probably has many intermed hosts with a final stage of maturity at a parasitic amoeba/protozoan, similar to many nana/capsular bacterium that are water borne.
At least one can study cell cycles easily with even a basic lab. Good textbook case study.
