^aATI phenotypes were counted in 50 infected cell sections at random. Values without parenthesis are actual numbers of ATI bodies and the values with the parenthesis are percentage of each phenotype relative to the total number of ATI phenotypes. ATIs have three phenotypes; the V⁺ ATI in which virions are embedded inside the ATI matrix, the V⁻ ATI lacks virions within and on the surface of the ATI matrix, and the V^+/ ATI in which the virions are not internalized within the inclusion but are encrusted on their surface[32].
