Fig. 5: Relative viral fitness of BA.2.75 and BA.5 in wild-type hamsters.
From: Characterization of SARS-CoV-2 Omicron BA.2.75 clinical isolates
BA.2.75 (TY41-716) and BA.5 (TY41-702) were mixed at a 1:1 (a), 1:3 (b), 1:19 (c), or 1:199 (d) ratio on the basis of their infectious titers, and the virus mixture (total 2 × 105 PFU in 60 µL) was intranasally inoculated into wild-type hamsters (n = 5). Nasal turbinates and lungs were collected from the infected animals at 4 dpi and analyzed using next-generation sequencing (NGS). Shown are the relative proportions of BA.5 and BA.2.75 in the infected wild-type animals. Data are from one experiment.
