^aMacrophage infectivity as a percent of infectivity recorded on HeLa TZM-BL cells. Most of this data is derived from that presented in Peters et al. [27] with the addition of SQ43 380.4.

^bBolded percentages indicate envelopes that were designated as macrophage-tropic i.e. >0.5% of infectivity for HeLa TZM-BL cells.
