From: Persistence of viral RNA in North American elk experimentally infected with an ancestral strain of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)

Figure 2

SARS-CoV-2 RNA detected via in situ hybridization (ISH) in the germinal centers of medial retropharyngeal lymph nodes of infected elk calves and cows. Medial retropharyngeal lymph nodes (mRPLN) from elk calves (a–c) and elk cows (d–f) experimentally infected with SARS-CoV-2. In both elk calves and cows, labeling was observed on 2 (a,d), 5 (b,e), and 21 (c,f) days post inoculation (p.i). Red labeling indicates presence of viral RNA within germinal centers (GC) or follicles (F). At days 2 and 5 p.i., this labeling is observed primarily within the marginal zone, while at day 21, labeling for SARS-CoV-2 RNA is seen within the GC.
