subtype

According to a 2015 study published in the Journal of Virology, which studied the virus when it was still new to science, H5N9 forms as a reassortment of other subtypes of the virus.

When she first went to the hospital she tested positive for influenza A — but not the seasonal subtype.

In finding her diagnosis, researchers say that she initially tested positive for influenza A, but not the seasonal subtype.

The results shows that PET did not pick up the metabolic differences between different tumour subtypes, so could not predict the type of tumour present.

It is particularly striking that the distribution of these subtypes changes with increasing aggressive of tumors.
